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.
* Add scaleway provider
this PR allows the entire scaleway stack to be managed with terraform
example usage looks like this:
```
provider "scaleway" {
api_key = "snap"
organization = "snip"
}
resource "scaleway_ip" "base" {
server = "${scaleway_server.base.id}"
}
resource "scaleway_server" "base" {
name = "test"
# ubuntu 14.04
image = "aecaed73-51a5-4439-a127-6d8229847145"
type = "C2S"
}
resource "scaleway_volume" "test" {
name = "test"
size_in_gb = 20
type = "l_ssd"
}
resource "scaleway_volume_attachment" "test" {
server = "${scaleway_server.base.id}"
volume = "${scaleway_volume.test.id}"
}
resource "scaleway_security_group" "base" {
name = "public"
description = "public gateway"
}
resource "scaleway_security_group_rule" "http-ingress" {
security_group = "${scaleway_security_group.base.id}"
action = "accept"
direction = "inbound"
ip_range = "0.0.0.0/0"
protocol = "TCP"
port = 80
}
resource "scaleway_security_group_rule" "http-egress" {
security_group = "${scaleway_security_group.base.id}"
action = "accept"
direction = "outbound"
ip_range = "0.0.0.0/0"
protocol = "TCP"
port = 80
}
```
Note that volume attachments require the server to be stopped, which can lead to
downtimes of you attach new volumes to already used servers
* Update IP read to handle 404 gracefully
* Read back resource on update
* Ensure IP detachment works as expected
Sadly this is not part of the official scaleway api just yet
* Adjust detachIP helper
based on feedback from @QuentinPerez in
https://github.com/scaleway/scaleway-cli/pull/378
* Cleanup documentation
* Rename api_key to access_key
following @stack72 suggestion and rename the provider api_key for more clarity
* Make tests less chatty by using custom logger
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.
