This commit adds the ability to provision files locally.
This is useful for cases where TerraForm generates assets
such as TLS certificates or templated documents that need
to be saved locally.
- While output variables can be used to return values to
the user, it is not extremly suitable for large content or
when many of these are generated, nor is it practical for
operators to manually save them on disk.
- While `local-exec` could be used with an `echo`, this
provider works across platforms and do not require any
convoluted escaping.
A couple commits got rebased together here, and it's easier to enumerate
them in a single commit.
Skip copying of states during migration if they are the same state. This
can happen when trying to reconfigure a backend's options, or if the
state was manually transferred. This can fail unexpectedly with locking
enabled.
Honor the `-input` flag for all confirmations (the new test hit some
more). Also unify where we reference the Meta.forceInitCopy and transfer
the value to the existing backendMigrateOpts.force field.
Add the -lock-timeout flag to the appropriate commands.
Add the -lock flag to `init` and `import` which were missing it.
Set both stateLock and stateLockTimeout in Meta.flagsSet, and remove the
extra references for clarity.
Add fields required to create an appropriate context for all calls to
clistate.Lock.
Add missing checks for Meta.stateLock, where we would attempt to lock,
even if locking should be skipped.
- Have the ui Lock helper use state.LockWithContext.
- Rename the message package to clistate, since that's how it's imported
everywhere.
- Use a more idiomatic placement of the Context in the LockWithContext
args.
Don't erase local state during backend migration if the new and old
paths are the same. Skipping the confirmation and copy are handled in
another patch, but the local state was always erased by default, even
when it was our new state.
It's possible to not change the backend config, but require updating the
stored backend state by moving init options from the config file to the
`-backend-config` flag. If the config is the same, but the hash doesn't
match, update the stored state.
This method mirrors that of config.Backend, so we can compare the
configration of a backend read from a config vs that of a backend read
from a state. This will prevent init from reinitializing when using
`-backend-config` options that match the existing state.
The variable validator assumes that any AST node it gets from an
interpolation walk is an indicator of an interpolation. Unfortunately,
back in f223be15 we changed the interpolation walker to emit a LiteralNode
as a way to signal that the result is a literal but not identical to the
input due to escapes.
The existence of this issue suggests a bit of a design smell in that the
interpolation walker interface at first glance appears to skip over all
literals, but it actually emits them in this one situation. In the long
run we should perhaps think about whether the abstraction is right here,
but this is a shallow, tactical change that fixes#13001.
golang/tools commit 23ca8a263 changed the format of the leading comment
to comply with some new standards discussed here:

This is the result of running generate with the latest version of
stringer. Everyone working on Terraform will need to update stringer
after this is merged, to avoid reverting this:
go get -u golang.org/x/tools/cmd/stringer
Environment names can be used in a number of contexts, and should be
properly escaped for safety. Since most state names are store in path
structures, and often in a URL, use `url.PathEscape` to check for
disallowed characters
The plan file should contain all data required to execute the apply
operation. Validation requires interpolation, and the `file()`
interpolation function may fail if the module files are not present.
This is the case currently with how TFE executes plans.
The `-force-copy` option will suppress confirmation for copying state
data.
Modify some tests to use the option, making sure to leave coverage of
the Input code path.
Fixes#12871
We were forgetting to remove the legacy remote state from the actual
state value when migrating. This only causes an issue when saving a plan
since the plan contains the state itself and causes an error where both
a backend + legacy state exist.
If saved plans aren't used this causes no noticable issue.
Due to buggy upgrades already existing in the wild, I also added code to
clear the remote section if it exists in a standard unchanged backend
Fixes#12806
This should've been part of 2c19aa69d9
This is the same issue, just missed a spot. Tests are hard to cover for
this since we're removing the legacy backends one by one, eventually
it'll be gone. A good sign is that we don't import backendlegacy at all
anymore in command/
This augments backend-config to also accept key=value pairs.
This should make Terraform easier to script rather than having to
generate a JSON file.
You must still specify the backend type as a minimal amount in
configurations, example:
```
terraform { backend "consul" {} }
```
This is required because Terraform needs to be able to detect the
_absense_ of that value for unsetting, if that is necessary at some
point.
Plans were properly encoding backend configuration but the apply was
reading it from the wrong field. :( This meant that every apply from a
plan was applying it locally with backends.
This needs to get released ASAP.
When migrating from a multi-state backend to a single-state backend, we
have to ensure that our locally configured environment is changed back
to "default", or we won't be able to access the new backend.
This allows a refresh on a non-existent or empty state file. We changed
this in 0.9.0 to error which seemed reasonable but it turns out this
complicates automation that runs refresh since it now needed to
determine if the state file was empty before running.
Its easier to just revert this into a warning with exit code zero.
The reason this changed is because in 0.8.x and earlier, the output
would be simply empty with exit code zero which seemed odd.
Fixes#12749
If we merge in an extra partial config we need to recompute the hash to
compare with the old value to detect that change.
This hash needs to NOT be stored and just used as a temporary. We want
to keep the original hash in the state so that we don't detect a change
from the config (since the config will always be partial).
