Add Env and SetEnv methods to command.Meta to retrieve the current
environment name inside any command.
Make sure all calls to Backend.State contain an environment name, and
make the package compile against the update backend package.
Destroying a terraform state can't always create an empty state, as
outputs and the root module may remain. Use HasResources to warn about
deleting an environment with resources.
In order to operate in parity with other commands, the env command
should take a path argument to locate the configuration.
This however introduces the issue of a possible name conflict between a
path and subcommand, or printing an incorrect current environment for
the bare `env` command. In favor of simplicity this removes the current
env output and only prints usage when no subcommand is provided.
I made this interface way back with the original backend work and I
guess I forgot to hook it up! This is becoming an issue as I'm working
on our 2nd enhanced backend that requires this information and I
realized it was hardcoded before.
This propertly uses the CLIInit interface allowing any backend to gain
access to this data.
Module resource were being sorted lexically by name by the state filter.
If there are 10 or more resources, the order won't match the index
order, and resources will have different indexes in their new location.
Sort the FilterResults by index numerically when the names match.
Clean up the module String output for visual inspection by sorting
Resource name parts numerically when they are an integer value.

Fixes#12154
The "-backup" flag before for "state *" CLI had some REALLY bizarre behavior:
it would change the _destination_ state and actually not create any
additional backup at all (the original state was unchanged and the
normal timestamped backup still are written). Really weird.
This PR makes the -backup flag work as you'd expect with one caveat:
we'll _still_ create the timestamped backup file. The timestamped backup
file helps make sure that you always get a backup history when using
these commands. We don't want to make it easy for you to overwrite a
state with the `-backup` flag.
We need to initialize the backend even if the config has no backend set.
This allows `init` to work when unsetting a previously set backend.
Without this, there was no way to unset a backend.
Gove LockInfo a Marshal method for easy serialization, and a String
method for more readable output.
Have the state.Locker implementations use LockError when possible to
return LockInfo and an error.
During backend initialization, especially during a migration, there is a
chance that an existing state could be overwritten.
Attempt to get a locks when writing the new state. It would be nice to
always have a lock when reading the states, but the recursive structure
of the Meta.Backend config functions makes that quite complex.
Remove the lock command for now to avoid confusion about the behavior of
locks. Rename lock to force-unlock to make it more aparent what it does.
Add a success message, and chose red because it can be a dangerous
operation.
Add confirmation akin to `destroy`, and a `-force` option for
automation and testing.
The new test pattern is to chdir into a temp location for the test, but
the prevents us from locating the testdata directory in the source. Add
a source path to testLockState so we can find the statelocker.go source.
Previously when runnign a plan with no exitsing state, the plan would be
written out and then backed up on the next WriteState by another
BackupState instance. Since we now maintain a single State instance
thoughout an operation, the backup happens before any state exists so no
backup file is created.
This is OK, as the backup state the tests were checking for is from the
plan file, which already exists separate from the state.
Terraform can't tell the difference between an empty output and an
undefined output. This is often confusing for folks using interpolation.
As much as it would be great to fix upstream, changing this error
message to be a bit more helpful is a good stop-gap to avoid
frustration.
The old behavior in this situation was to simply delete the file. Since
we now have a lock on this file we don't want to close or delete it, so
instead truncate the file at offset 0.
Fix a number of related tests
Having the state files always created for locking breaks a lot of tests.
Most can be fixed by simple checking for state within a file, but a few
still might be writing state when they shouldn't.

Putting metas inside single-item lists. This is clunky, but I couldn't

know a better way?
Inside the meta struct, all fields are always written to the state; I
can't figure out how to omit fields that aren't used. This is not just
verbose, it actually causes issues because you can't have both "up" and
"up_feed" set).

* "external" provider for gluing in external logic
This provider will become a bit of glue to help people interface external
programs with Terraform without writing a full Terraform provider.
It will be nowhere near as capable as a first-class provider, but is
intended as a light-touch way to integrate some pre-existing or custom
system into Terraform.
* Unit test for the "resourceProvider" utility function
This small function determines the dependable name of a provider for
a given resource name and optional provider alias. It's simple but it's
a key part of how resource nodes get connected to provider nodes so
worth specifying the intended behavior in the form of a test.
* Allow a provider to export a resource with the provider's name
If a provider only implements one resource of each type (managed vs. data)
then it can be reasonable for the resource names to exactly match the
provider name, if the provider name is descriptive enough for the
purpose of the each resource to be obvious.
* provider/external: data source
A data source that executes a child process, expecting it to support a
particular gateway protocol, and exports its result. This can be used as
a straightforward way to retrieve data from sources that Terraform
doesn't natively support..

Fixes#10412
The context wasn't properly adding variable values to the Interpolator
instance which made it so that the `console` command couldn't access
variables set via tfvars and the CLI.
This also adds better test coverage in command itself for this.
Fixes#10337
The `reset_bold` escape code (21) causes the text on Windows command
prompts to just become invisible. `reset` does the same job for us in
this scenario so do that.
Add `terraform debug json2dot` to convert debug log graphs to dot
format. This is not meant to be in place of more advanced debug
visualization, but may continue to be a useful way to work with the
debug output.
The dot format generation was done with a mix of code from the terraform
package and the dot package. Unify the dot generation code, and it into
the dag package.
Use an intermediate structure to allow a dag.Graph to marshal itself
directly. This structure will be ablt to marshal directly to JSON, or be
translated to dot format. This was we can record more information about
the graph in the debug logs, and provide a way to translate those logged
structures to dot, which is convenient for viewing the graphs.
This turns the new graphs on by default and puts the old graphs behind a
flag `-Xlegacy-graph`. This effectively inverts the current 0.7.x
behavior with the new graphs.
We've incubated most of these for a few weeks now. We've found issues
and we've fixed them and we've been using these graphs internally for
awhile without any major issue. Its time to default them on and get them
part of a beta.
Fixes#7774
This modifies the `import` command to load configuration files from the
pwd. This also augments the configuration loading section for the CLI to
have a new option (default false, same as old behavior) to
allow directories with no Terraform configurations.
For import, we allow directories with no Terraform configurations so
this option is set to true.
Implement debugInfo and the DebugGraph
DebugInfo will be a global variable through which graph debug
information can we written to a compressed archive. The DebugInfo
methods are all safe for concurrent use, and noop with a nil receiver.
The API outside of the terraform package will be to call SetDebugInfo
to create the archive, and CloseDebugInfo() to properly close the file.
Each write to the archive will be flushed and sync'ed individually, so
in the event of a crash or a missing call to Close, the archive can
still be recovered.
The DebugGraph is a representation of a terraform Graph to be written to
the debug archive, currently in dot format. The DebugGraph also contains
an internal buffer with Printf and Write methods to add to this buffer.
The buffer will be written to an accompanying file in the debug archive
along with the graph.
This also adds a GraphNodeDebugger interface. Any node implementing
`NodeDebug() string` can output information to annotate the debug graph
node, and add the data to the log. This interface may change or be
removed to provide richer options for debugging graph nodes.
The new graph builders all delegate the build to the BasicGraphBuilder.
Having a Name field lets us differentiate the actual builder
implementation in the debug graphs.
Fixes#7975
This changes the InputMode for the CLI to always be:
InputModeProvider | InputModeVar | InputModeVarUnset
Which means:
* Ask for provider variables
* Ask for user variables _that are not already set_
The change is the latter point. Before, we'd only ask for variables if
zero were given. This forces the user to either have no variables set
via the CLI, env vars, tfvars or ALL variables, but no in between. As
reported in #7975, this isn't expected behavior.
The new change makes is so that unset variables are always asked for.
Users can retain the previous behavior by setting `-input=false`. This
would ensure that variables set by external sources cover all cases.
To reduce the risk of secret exposure via Terraform state and log output,
we default to creating a relatively-short-lived token (20 minutes) such
that Vault can, where possible, automatically revoke any retrieved
secrets shortly after Terraform has finished running.
This has some implications for usage of this provider that will be spelled
out in more detail in the docs that will be added in a later commit, but
the most significant implication is that a plan created by "terraform plan"
that includes secrets leased from Vault must be *applied* before the
lease period expires to ensure that the issued secrets remain valid.
No resources yet. They will follow in subsequent commits.
Fixes#5409
I didn't expect this to be such a rabbit hole!
Based on git history, it appears that for "historical reasons"(tm),
setting up the various `state.State` structures for a plan were
_completely different logic_ than a normal `terraform apply`. This meant
that it was skipping things like disabling backups with `-backup="-"`.
This PR unifies loading from a plan to the normal state setup mechanism.
A few tests that were failing prior to this PR were added, no existing
tests were changed.
When passing a bool type to a variable such as `-var foo=true`, the CLI
would parse this as a `bool` type which Terraform core cannot handle.
It would then error with an invalid type error.
This changes the handling to convert the bool to its literally string
value given on the command-line.
This creates a standard package and interface for defining, querying,
setting experiments (`-X` flags).
I expect we'll want to continue to introduce various features behind
experimental flags. I want to make doing this as easy as possible and I
want to make _removing_ experiments as easy as possible as well.
The goal with this packge has been to rely on the compiler enforcing our
experiment references as much as possible. This means that every
experiment is a global variable that must be referenced directly, so
when it is removed you'll get compiler errors where the experiment is
referenced.
This also unifies and makes it easy to grab CLI flags to enable/disable
experiments as well as env vars! This way defining an experiment is just
a couple lines of code (documented on the package).
Since it is still very much possible for this to cause problems, this
can be used to disable the shadow graph. We'll purposely not document
this since the goal is to remove this flag as we become more confident
with it.
Wait for our expected number of goroutines to be staged and ready, then
allow Run() to complete. Use a high-water-mark counter to ensure we
never exceeded the max expected concurrent goroutines at any point
during the run.
When we parse a map from HCL, it's decoded into a list of maps because
HCL allows declaring a key multiple times to implicitly add it to a
list. Since there's no terraform variable configuration that supports
this structure, we can always flatten a []map[string]interface{} value
to a map[string]interface{} and remove any type rrors trying to apply
that value.
Don't try to parse a varibale as HCL if the value can be parse as a
single number. HCL will always attempt to convert the value to a number,
even if we later find the configured variable's type to be a string.
This commit adds the `state rm` command for removing an address from
state. It is the result of a rebase from pull-request #5953 which was
lost at some point during the Terraform 0.7 feature branch merges.
Fix checksum issue with remote state
If we read a state file with "null" objects in a module and they become
initialized to an empty map the state file may be written out with empty
objects rather than "null", changing the checksum. If we can detect
this, increment the serial number to prevent a conflict in atlas.
Our fakeAtlas test server now needs to decode the state directly rather
than using the ReadState function, so as to be able to read the state
unaltered.
The terraform.State data structures have initialization spread out
throughout the package. More thoroughly initialize State during
ReadState, and add a call to init() during WriteState as another
normalization safeguard.
Expose State.init through an exported Init() method, so that a new State
can be completely realized outside of the terraform package.
Additionally, the internal init now completely walks all internal state
structures ensuring that all maps and slices are initialized. While it
was mentioned before that the `init()` methods are problematic with too
many call sites, expanding this out better exposes the entry points that
will need to be refactored later for improved concurrency handling.
The State structures had a mix of `omitempty` fields. Remove omitempty
for all maps and slices as part of this normalization process. Make
Lineage mandatory, which is now explicitly set in some tests.
Some Atlas usage patterns expect to be able to override a variable set
in Atlas, even if it's not seen in the local context. This allows
overwriting a variable that is returned from atlas, and sends it back.
Also use a unique sential value in the context where we have variables
from atlas. This way atals variables aren't combined with the local
variables, and we don't do something like inadvertantly change the type,
double encode/escape, etc.
If we have a number value in our config variables, format it as a
string, and send it with the HCL=true flag just in case.
Also use %g for for float encoding, as the output is a generally a
little friendlier.
Set the default log package output to iotuil.Discard during tests if the
`-v` flag isn't set. If we are verbose, then apply the filter according
to the TF_LOG env variable.
The behaviour whereby outputs for a particular nested module can be
output was broken by the changes for lists and maps. This commit
restores the previous behaviour by passing the module path into the
outputsAsString function.
We also add a new test of this since the code path for indivdual output
vs all outputs for a module has diverged.
The handling of remote variables was completely disabled for push.
We still need to fetch variables from atlas for push, because if the
variable is only set remotely the Input walk will still prompt the user
for a value. We add the missing remote variables to the context
to disable input.
We now only handle remote variables as atlas.TFVar and explicitly pass
around that type rather than an `interface{}`.
Shorten the text fixture slightly to make the output a little more
readable on failures.
The strings we have in the variables may contain escaped double-quotes,
which have already been parsed and had the `\`s removed. We need to
re-escape these, but only if we are in the outer string and not inside an
interpolation.
Add tf_vars to the data structures sent in terraform push.
This takes any value of type []interface{} or map[string]interface{} and
marshals it as a string representation of the equivalent HCL. This
prevents ambiguity in atlas between a string that looks like a json
structure, and an actual json structure.
For the time being we will need a way to serialize data as HCL, so the
command package has an internal encodeHCL function to do so. We can
remove this if we get complete package for marshaling HCL.
Terraform 0.7 introduces lists and maps as first-class values for
variables, in addition to string values which were previously available.
However, there was previously no way to override the default value of a
list or map, and the functionality for overriding specific map keys was
broken.
Using the environment variable method for setting variable values, there
was previously no way to give a variable a value of a list or map. These
now support HCL for individual values - specifying:
TF_VAR_test='["Hello", "World"]'
will set the variable `test` to a two-element list containing "Hello"
and "World". Specifying
TF_VAR_test_map='{"Hello = "World", "Foo" = "bar"}'
will set the variable `test_map` to a two-element map with keys "Hello"
and "Foo", and values "World" and "bar" respectively.
The same logic is applied to `-var` flags, and the file parsed by
`-var-files` ("autoVariables").
Note that care must be taken to not run into shell expansion for `-var-`
flags and environment variables.
We also merge map keys where appropriate. The override syntax has
changed (to be noted in CHANGELOG as a breaking change), so several
tests needed their syntax updating from the old `amis.us-east-1 =
"newValue"` style to `amis = "{ "us-east-1" = "newValue"}"` style as
defined in TF-002.
In order to continue supporting the `-var "foo=bar"` type of variable
flag (which is not valid HCL), a special case error is checked after HCL
parsing fails, and the old code path runs instead.
This is the first step in allowing overrides of map and list variables.
We convert Context.variables to map[string]interface{} from
map[string]string and fix up all the call sites.

This commit removes the ability to index into complex output types using
`terraform output a_list 1` (for example), and adds a `-json` flag to
the `terraform output` command, such that the output can be piped
through a post-processor such as jq or json. This removes the need to
allow arbitrary traversal of nested structures.
It also adds tests of human readable ("normal") output with nested lists
and maps, and of the new JSON output.
When working from an existing plan, we weren't setting the PathOut field
for a LocalState. This required adding an outPath argument to the
StateFromPlan function to avoid having to introspect the returned
state.State interface to find the appropriate field.
To test we run a plan first and provide the new plan to apply with
`-state-out` set.
Data sources are given a special plan output when the diff would show it
creating a new resource, to indicate that there is only a logical data
resource being read. Data sources nested in modules weren't formatted in
the plan output in the same way.
This checks for the "data." part of the path in nested modules, and adds
acceptance tests for the plan output.
In cases where we construct state directly rather than reading it via
the usual methods, we need to ensure that the necessary maps are
initialized correctly.
This commit fixes a crash in `terraform show` where there is no primary
resource, but there is a tainted resource, because of the changes made
to tainted resource handling in 0.7.
This an effort to address hashicorp/terraform#516.
Adding the Sensitive attribute to the resource schema, opening up the
ability for resource maintainers to mark some fields as sensitive.
Sensitive fields are hidden in the output, and, possibly in the future,
could be encrypted.
This means it’s shown correctly in a plan and takes into account any
actions that are dependant on the tainted resource and, vice verse, any
actions that the tainted resource depends on.
So this changes the behaviour from saying this resource is tainted so
just forget about it and make sure it gets deleted in the background,
to saying I want that resource to be recreated (taking into account the
existing resource and it’s place in the graph).
This commit forward ports the changes made for 0.6.17, in order to store
the type and sensitive flag against outputs.
It also refactors the logic of the import for V0 to V1 state, and
fixes up the call sites of the new format for outputs in V2 state.
Finally we fix up tests which did not previously set a state version
where one is required.
This provider will have logical resources that allow Terraform to "manage"
randomness as a resource, producing random numbers on create and then
retaining the outcome in the state so that it will remain consistent
until something explicitly triggers generating new values.
Managing randomness in this way allows configurations to do things like
random distributions and ids without causing "perma-diffs".
Internally a data source read is represented as a creation diff for the
resource, but in the UI we'll show it as a distinct icon and color so that
the user can more easily understand that these operations won't affect
any real infrastructure.
Unfortunately by the time we get to formatting the plan in the UI we
only have the resource names to work with, and can't get at the original
resource mode. Thus we're forced to infer the resource mode by exploiting
knowledge of the naming scheme.
New resources logically don't have "old values" for their attributes, so
showing them as updates from the empty string is misleading and confusing.
Instead, we'll skip showing the old value in a creation diff.
Data resources don't have ids when they refresh, so we'll skip showing the
"(ID: ...)" indicator for these. Showing it with no id makes it look
like something is broken.
Since the data resource lifecycle contains no steps to deal with tainted
instances, we must make sure that they never get created.
Doing this out in the command layer is not the best, but this is currently
the only layer that has enough information to make this decision and so
this simple solution was preferred over a more disruptive refactoring,
under the assumption that this taint functionality eventually gets
reworked in terms of StateFilter anyway.
- Fix sensitive outputs for lists and maps
- Fix test prelude which was missed during conflict resolution
- Fix `terraform output` to match old behaviour and not have outputs
header and colouring
- Bump timeout on TestAtlasClient_UnresolvableConflict
This introduces the terraform state list command to list the resources
within a state. This is the first of many state management commands to
come into 0.7.
This is the first command of many to come that is considered a
"plumbing" command within Terraform (see "plumbing vs porcelain":
http://git.661346.n2.nabble.com/what-are-plumbing-and-porcelain-td2190639.html).
As such, this PR also introduces a bunch of groundwork to support
plumbing commands.
The main changes:
- Main command output is changed to split "common" and "uncommon"
commands.
- mitchellh/cli is updated to support nested subcommands, since
terraform state list is a nested subcommand.
- terraform.StateFilter is introduced as a way in core to filter/search
the state files. This is very basic currently but I expect to make it
more advanced as time goes on.
- terraform state list command is introduced to list resources in a
state. This can take a series of arguments to filter this down.
Known issues, or things that aren't done in this PR on purpose:
- Unit tests for terraform state list are on the way. Unit tests for the
core changes are all there.
This changes the representation of maps in the interpolator from the
dotted flatmap form of a string variable named "var.variablename.key"
per map element to use native HIL maps instead.
This involves porting some of the interpolation functions in order to
keep the tests green, and adding support for map outputs.
There is one backwards incompatibility: as a result of an implementation
detail of maps, one could access an indexed map variable using the
syntax "${var.variablename.key}".
This is no longer possible - instead HIL native syntax -
"${var.variablename["key"]}" must be used. This was previously
documented, (though not heavily used) so it must be noted as a backward
compatibility issue for Terraform 0.7.
This commit adds the groundwork for supporting module outputs of types
other than string. In order to do so, the state version is increased
from 1 to 2 (though the "public-facing" state version is actually as the
first state file was binary).
Tests are added to ensure that V2 (1) state is upgraded to V3 (2) state,
though no separate read path is required since the V2 JSON will
unmarshal correctly into the V3 structure.
Outputs in a ModuleState are now of type map[string]interface{}, and a
test covers round-tripping string, []string and map[string]string, which
should cover all of the types in question.
Type switches have been added where necessary to deal with the
interface{} value, but they currently default to panicking when the input
is not a string.
This adds a field terraform_version to the state that represents the
Terraform version that wrote that state. If Terraform encounters a state
written by a future version, it will error. You must use at least the
version that wrote that state.
Internally we have fields to override this behavior (StateFutureAllowed),
but I chose not to expose them as CLI flags, since the user can just
modify the state directly. This is tricky, but should be tricky to
represent the horrible disaster that can happen by enabling it.
We didn't have to bump the state format version since the absense of the
field means it was written by version "0.0.0" which will always be
older. In effect though this change will always apply to version 2 of
the state since it appears in 0.7 which bumped the version for other
purposes.

* core: Add support for marking outputs as sensitive
This commit allows an output to be marked "sensitive", in which case the
value is redacted in the post-refresh and post-apply list of outputs.
For example, the configuration:
```
variable "input" {
default = "Hello world"
}
output "notsensitive" {
value = "${var.input}"
}
output "sensitive" {
sensitive = true
value = "${var.input}"
}
```
Would result in the output:
```
terraform apply
Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
Outputs:
notsensitive = Hello world
sensitive = <sensitive>
```
The `terraform output` command continues to display the value as before.
Limitations: Note that sensitivity is not tracked internally, so if the
output is interpolated in another module into a resource, the value will
be displayed. The value is still present in the state.
* command/fmt: Document -diff doesn't disable -write
As noted in hashicorp/terraform#6343, this description misleadingly
suggested that the `-diff` option disables the `-write` option.
This isn't the case and because of the default options (described in
c753390) the behaviour of `terraform fmt -diff` is actually the same as
`terraform fmt -write -list -diff`.
Replace the "instead of rewriting" description to clarify that.
Documentation in hcl/fmtcmd is corrected in hashicorp/hcl#117 but it's not
really necessary to bump the dependency version.
* command/fmt: Show flag defaults in help text
These were documented on the website but not in the `-help` text. This
should help to clarify that you need to pass `-list=false -write=false
-diff` if you only want to see diffs.
Accordingly I've replaced the word "disabled" with "always false" in the
STDIN special cases so that it matches the terminology used in the defaults
and better indicates that it is overridden.
NB: The 3x duplicated defaults and documentation makes me feel uneasy once
again. I'm not sure how to solve that, though.
These options don't make sense when passing STDIN. `-write` will raise an
error because there is no file to write to. `-list` will always say
`<standard input>`. So disable whenever using STDIN, making the command
much simpler:
cat main.tf | terraform fmt -
So that you can do automatic formatting from an editor. You probably want to
disable the `-write` and `-list` options so that you just get the
re-formatted content, e.g.
cat main.tf | terraform fmt -write=false -list=false -
I've added a non-exported field called `input` so that we can override this
for the tests. If not specified, like in `commands.go`, then it will default
to `os.Stdin` which works on the command line.
The most common usage usage will be enabling the `-write` and `-list`
options so that files are updated in place and a list of any modified files
is printed. This matches the default behaviour of `go fmt` (not `gofmt`). So
enable these options by default.
This does mean that you will have to explicitly disable these if you want to
generate valid patches, e.g. `terraform fmt -diff -write=false -list=false`
This uses the `fmtcmd` package which has recently been merged into HCL. Per
the usage text, this rewrites Terraform config files to their canonical
formatting and style.
Some notes about the implementation for this initial commit:
- all of the fmtcmd options are exposed as CLI flags
- it operates on all files that have a `.tf` suffix
- it currently only operates on the working directory and doesn't accept a
directory argument, but I'll extend this in subsequent commits
- output is proxied through `cli.UiWriter` so that we write in the same way
as other commands and we can capture the output during tests
- the test uses a very simple fixture just to ensure that it is working
correctly end-to-end; the fmtcmd package has more exhaustive tests
- we have to write the fixture to a file in a temporary directory because it
will be modified and for this reason it was easier to define the fixture
contents as a raw string
This means that terraform commands like `plan`, `apply`, `show`, and
`graph` will expand all modules by default.
While modules-as-black-boxes is still very true in the conceptual design
of modules, feedback on this behavior has consistently suggested that
users would prefer to see more verbose output by default.
The `-module-depth` flag and env var are retained to allow output to be
optionally limited / summarized by these commands.
