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.
If users run "terraform import" in a directory with no Terraform
configuration files, it's likely that they've made a mistake either by
being in the wrong directory or forgetting to use the -config option
on the command line.
To help users find their mistake in this case, we'll now produce a
specialized error message for this situation:
Error: No Terraform configuration files
The directory /home/user/example does not contain any Terraform
configuration files (.tf or .tf.json). To specify a different
configuration directory, use the -config="..." command line option.
While here, this also converts some of the other existing messages to
diagnostics so that we can show any configuration warnings along with
the error message, and move towards the new standard error presentation.
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.
This new option allows importing without configuration present.
Configuration is required by default as a confirmation that the provided resource name is correct, but it can be useful to override this in tools that wrap Terraform to do more involved operations.
Fix the -state and -state-out wording to be consistent with other
commands. Remove the erroneous reference to remote state in the website
version of the flag description.
While the `local.Local` backend is the only implementation of
`backend.Local`, creating the backend with `ForceLocal` bypasses the
`backend.Backend` in the `local.Local` causing a local state to be
implicitly created rather than using the configured state backend.
Add a test that imports into a configured backend (using the "local"
backend as a remote state proxy). This further confirms the confusing
nature of ForceLocal, as the backend _is_ local, but not from the
viewpoint of meta.Backend.
The import command wasn't loading the plugin path at all, relying on the
local directory for binaries.
Load the plugin dir into Meta, and pass in ForceLocal for consistency.
The Backend returned was going to be a Local anyway, so the added check
wasn't ensuring anything.
Previously we encouraged users to import a resource and _then_ write the
configuration block for it. This ordering creates lots of risk, since
for various reasons users can end up subsequently running Terraform
without any configuration in place, which then causes Terraform to want
to destroy the resource that was imported.
Now we invert this and require a minimal configuration block be written
first. This helps ensure that the user ends up with a correlated resource
config and state, protecting against any inconsistency caused by typos.
This addresses #11835.
Previously we deferred validation of the resource address on the import
command until we were in the core guts, which caused the error responses
to be rather unhelpful.
By validating these things early we can give better feedback to the user.
Instead of providing the a path in BackendOpts, provide a loaded
*config.Config instead. This reduces the number of places where
configuration is loaded.
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.
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.
