This command serves as an alternative to the human-oriented list of workspaces for scripting use-cases where it's useful to know the _current_ workspace name.
Skips checksum validation if the `TF_SKIP_PROVIDER_VERIFY` environment variable is set. Undocumented variable, as the primary goal is to significantly improve the local provider development workflow.
We need to release the lock just before deleting the state, in case the backend
can't remove the resource while holding the lock. This is currently true for
Windows local files.
TODO: While there is little safety in locking while deleting the state, it
might be nice to be able to coordinate processes around state deletion, i.e. in
a CI environment. Adding Delete() as a required method of States would allow
the removal of the resource to be delegated from the Backend to the State
itself.
A common reason to want to use `terraform plan` is to have a chance to
review and confirm a plan before running it. If in fact that is the
only reason you are running plan, this new `terraform apply -auto-approve=false`
flag provides an easier alternative to
P=$(mktemp -t plan)
terraform refresh
terraform plan -refresh=false -out=$P
terraform apply $P
rm $P
The flag defaults to true for now, but in a future version of Terraform it will
default to false.
The import command wasn't loading the full plugin path for discovery.
Run a basic plugin init sequence, and verify we can find a plugin (even
though the plugin is invalid and will fail).
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.
The "confirm" method was directly checking the meta struct's input field,
but that only represents the -input command line flag, and doesn't
respect the TF_INPUT environment variable.
By calling the Input method instead, we check both.
This fixes#15338.
When using a `state` command, if the `-state` flag is provided we do not
want to modify the Backend state. In this case we should always create a
local state instance.
The backup flag was also being ignored, and some tests were relying on
that, which have been fixed.
If we provide a -state flag to a state command, we do not want terraform
to modify the backend state. This test fails since the state specified
in the backend doesn't exist
Remove "checksum" from the error, and only indicate that the plugin has
changed.
Always show requested versions even if it's "any", and found versions of
plugins.
This change makes various minor adjustments to the rendering of plans
in the output of "terraform plan":
- Resources are identified using the standard resource address syntax,
rather than exposing the legacy internal representation used in the
module diff resource keys. This fixes#8713.
- Subjectively, having square brackets in the addresses made it look more
visually "off" when the same name but with different indices were
shown together with differing-length "symbols", so the symbols are now
all padded and right-aligned to three characters for consistent layout
across all operations.
- The -/+ action is now more visually distinct, using several different
colors to help communicate what it will do and including a more obvious
"(new resource required)" marker to help draw attention to this not
being just an update diff. This fixes#15350.
- The resources are now sorted in a manner that sorts index [10] after
index [9], rather than after index [1] as we did before. This makes it
easier to scan the list and avoids the common confusion where it seems
that there are only 10 items when in fact there are 11-20 items with
all the tens hiding further up in the list.
Previously init would crash if given these options:
-backend=false -get-plugins=true
This is because the state is used as a source of provider dependency
information, and we need to instantiate the backend to get the state.
To avoid the crash, we now use the following adjusted behavior:
- if -backend=true, we behave as before
- if -backend=false, we instead try to instantiate the backend the same
way any other command would, without modifying its configuration
- if we're able to instantiate the backend, we use it to fetch state
for dependency resolution purposes
- if the backend is not instantiable then we assume it's not yet
configured and proceed with a nil state, which may cause us to see an
incomplete picture of the dependencies but still allows the install
to succeed. Subsequently running "terraform plan" will not work until
the backend is (re-)initialized, so the incomplete picture of required
plugins is safe.
This takes care of a few dangling cases where we were still stringifying
empty version constraints, which creates confusing error messages due to
it stringing as the empty string.
For the "no suitable versions available" message, we fall back on the
"provider not found" message if no versions were found even though it's
unconstrained. This should only happen in an edge case where the
provider's index page exists on the releases server but no versions are
yet present.
For the message about plugin protocol versions, this again is an edge
case since with no constraints this should happen only if we release
an incompatible Terraform version but don't release a new version of the
plugin that's compatible. In this case we just show the constraint as
"(any version)" to make sure we always show _something_.
Previously we only did this when _upgrading_, but that's unnecessarily
specific and confusing since e.g. plugins can get upgraded implicitly by
constraint changes, which would not then trigger the purge process.
Instead, we'll assume that the user is able to easily re-download plugins
that were purged here, or if they need more specific guarantees they will
manage manually a plugin directory and disable the auto-install behavior
using `-plugin-dir`.
Now we are able to recognize and handle a few special error situations
from plugin installation with more verbose error messages that give the
user better feedback on how to proceed.
The -plugin-dir option lets the user specify custom search paths for
plugins. This overrides all other plugin search paths, and prevents the
auto-installation of plugins.
We also make sure that the availability of plugins is always checked
during init, even if -get-plugins=false or -plugin-dir is set.
init should always write intternal data to the current directory, even
when a path is provided. The inherited behavior no longer applies to the
new use of init.
Now that init can take a directory for configuration, the old behavior
of writing the .terraform data directory into the target path no longer
makes sense. Don't change the dataDir field during init, and write to
the default location.
Clean up all references to Meta.dataDir, and only use the getter method
in case we chose to dynamically override this at some point.
Now when -upgrade is provided to "terraform init" (and plugin installation
isn't disabled) it will:
- ignore the contents of the auto-install plugin directory when deciding
what is "available", thus causing anything there to be reinstalled,
possibly at a newer version.
- if installation completes successfully, purge from the auto-install
plugin directory any plugin-looking files that aren't in the set of
chosen plugins.
As before, plugins outside of the auto-install directory are able to
take precedence over the auto-install ones, and these will never be
upgraded nor purged.
The thinking here is that the auto-install directory is an implementation
detail directly managed by Terraform, and so it's Terraform's
responsibility to automatically keep it clean as plugins are upgraded.
We don't yet have the -plugin-dir option implemented, but once it is it
should circumvent all of this behavior and just expect providers to be
already available in the given directory, meaning that nothing will be
auto-installed, -upgraded or -purged.
Previously we had a "getProvider" function type used to implement plugin
fetching. Here we replace that with an interface type, initially with
just a "Get" function.
For now this just simplifies the interface by allowing the target
directory and protocol version to be members of the struct rather than
passed as arguments.
A later change will extend this interface to also include a method to
purge unused plugins, so that upgrading frequently doesn't leave behind
a trail of unused executable files.
As of this commit this just upgrades modules, but this option will also
later upgrade plugins and indeed anything else that's being downloaded and
installed as part of the init.
Since there is little left that isn't core, remove the distinction for
now to reduce confusion, since a "core" binary will mostly work except
for provisioners.
We're shifting terminology from "environment" to "workspace". This takes
care of some of the main internal API surface that was using the old
terminology, though is not intended to be entirely comprehensive and is
mainly just to minimize the amount of confusion for maintainers as we
continue moving towards eliminating the old terminology.
