This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.
If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.
The remote API this talks to will be going away very soon, before our next
major release, and so we'll remove the command altogether in that release.
This also removes the "encodeHCL" function, which was used only for
adding a .tfvars-formatted file to the uploaded archive.
The state locking improvements for the regular command had the side
effect of locking the state in the console, import, graph and push
commands. Those commands had been updated to get a state via the
Backend.Context method, which locks the state whenever possible, and now
need to call Unlock directly.
Add Unlock calls to all commands that call Context directly.
Previously we required callers to separately call .Validate on the root
module to determine if there were any value errors, but we did that
inconsistently and would thus see crashes in some cases where later code
would try to use invalid configuration as if it were valid.
Now we run .Validate automatically after config loading, returning the
resulting diagnostics. Since we return a diagnostics here, it's possible
to return both warnings and errors.
We return the loaded module even if it's invalid, so callers are free to
ignore returned errors and try to work with the config anyway, though they
will need to be defensive against invalid configuration themselves in
that case.
As a result of this, all of the commands that load configuration now need
to use diagnostic printing to signal errors. For the moment this just
allows us to return potentially-multiple config errors/warnings in full
fidelity, but also sets us up for later when more subsystems are able
to produce rich diagnostics so we can show them all together.
Finally, this commit also removes some stale, commented-out code for the
"legacy" (pre-0.8) graph implementation, which has not been available
for some time.
Update all references to the version values to use the new package.
The VersionString function was left in the terraform package
specifically for the aws provider, which is vendored. We can remove that
last call once the provider is updated.
Feedback after 0.9 was that the term "environment" was confusing due to
it colliding with several other concepts, such as OS environment
variables, a non-aligned Terraform Enterprise concept, and differing ideas
of "environment" within various organizations.
This new term "workspace" is intended to ease some of that confusion. This
term is not used anywhere else in Terraform today, and we expect it to not
be used in a manner that would be confusing within user organizations.
This begins a deprecation cycle for the "terraform env" family of commands,
instead moving to an equivalent set of "terraform workspace" commands.
There are some remaining references to the old "environment" concept in
the code, which will be cleaned up in a separate change. This change is
instead focused on text visible in the UI and wording within code comments
for the benefit of human maintainers of the code.
Instead of providing the a path in BackendOpts, provide a loaded
*config.Config instead. This reduces the number of places where
configuration is loaded.
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.
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.
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.
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.
