* hcl2template: use && for chaining conditions
For deciding if we need to run an error provisioner block, we checked
using a nested if that we didn't need to avoid running it.
This is unnecessary, and adds a superfluous level of inbrication to the
code, so we chain both conditions with &&.
* hcl2: don't warn on excluded post-processor
When a post-processor is excluded through the -except command-line
argument for packer build, we used to print a warning on HCL2 templates
if this except statement did not match a build.
However, since we can use the except option to avoid running
post-processors, we should account for this as well when printing out a
warning that there were no matches.
This commit adds this counter to the except checks for the
post-processors as well.
This commit irons out one of the pain points of the HCP rework by
introducing a HCPPublisher interface, implemented both by the JSON Core,
and the HCL2 PackerConfig, which keeps a map of the build names used by
Packer to the build names pushed on HCP.
This in turn lets us go back to the old implementation of the GetBuilds
function, which returns a list of (filtered) builds, and eventually an
error if something went wrong while processing.
* Update validation options for undeclared variables
In an effort to help users move from JSON to HCL2 templates the support for
variable definitions files are being updated to ignore undeclared
variable warnings on build execution. For legacy JSON templates builds no
warnings are displayed when var-files contain undeclared variables.
Since preferred mode HCL2 templates is to be explicit with variable
declarations - they must be declared to be used - validation for
undeclared variables still warns when running `packer validate`. A new
flag has been added to the validate command that can be used to disable
undeclared variable warnings.
* Update validation test for unused variables
Example Run
```
~> go run . validate -no-warn-undeclared-var -var-file
command/test-fixtures/validate/var-file-tests/undeclared.pkrvars.hcl
command/test-fixtures/validate/var-file-tests/basic.pkr.hcl
The configuration is valid.
~> go run . validate -var-file
command/test-fixtures/validate/var-file-tests/undeclared.pkrvars.hcl
command/test-fixtures/validate/var-file-tests/basic.pkr.hcl
Warning: Undefined variable
The variable "unused" was set but was not declared as an input variable.
To declare variable "unused" place this block in one of your .pkr.hcl
files,
such as variables.pkr.hcl
variable "unused" {
type = string
default = null
}
The configuration is valid.
~> go run . build -var-file
command/test-fixtures/validate/var-file-tests/undeclared.pkrvars.hcl
command/test-fixtures/validate/var-file-tests/basic.pkr.hcl
file.chocolate: output will be in this color.
Build 'file.chocolate' finished after 744 microseconds.
==> Wait completed after 798 microseconds
==> Builds finished. The artifacts of successful builds are:
--> file.chocolate: Stored file: chocolate.txt
```
* Rename Strict field to WarnOnUndeclaredVar
The field name Strict is a bit vague since it is only used for
checking against undeclared variables within a var-file definition.
To mitigate against potential overloading of this field it is
being renamed to be more explicit on its usage.
* command/build: Add warn-on-undeclared-var flag
Now that the default behaviour is to not display warnings for undeclared variables
an optional flag has been added to toggle the old behaviour.
```
~> go run . build -warn-on-undeclared-var -var-file command/test-fixtures/validate/var-file-tests/undeclared.pkrvars.hcl command/test-fixtures/validate/var-file-tests/basic.pkr.hcl
Warning: Undefined variable
The variable "unused" was set but was not declared as an input variable.
To declare variable "unused" place this block in one of your .pkr.hcl files,
such as variables.pkr.hcl
variable "unused" {
type = string
default = null
}
file.chocolate: output will be in this color.
Build 'file.chocolate' finished after 762 microseconds.
==> Wait completed after 799 microseconds
==> Builds finished. The artifacts of successful builds are:
--> file.chocolate: Stored file: chocolate.txt
```
When a template describes a build block without a source reference, the
build should be considered invalid as we won't have a CoreBuild produced
as a result of the need to have both.
In current versions of Packer, this will produce an error message
hinting that nothing will happen because of the lack of either build or
source block.
This commit takes the defined block, and points out to it as missing a
source block as being the reason why nothing is happening, making it
clearer what is required for an HCL2 build to be processed.
When a variable is set in a pkrvars file, but isn't defined, an error
message is output, but does not deliver an example of what is expected
by Packer in order to complete a build.
To remedy that, we improve the error message by giving an example of
variable block to include in the build template.
When a template with some builds to run ends its GetBuilds with an
error, and no builds produced, we can exit immediately without printing
more errors.
This commit replaces `os.Setenv` with `t.Setenv` in tests. The
environment variable is automatically restored to its original value
when the test and all its subtests complete.

When a `packer build' is run on a config that does not define anything
to be built, the process would run normally, and only state that no
artifacts were produced after builds were run successfully.
This is misleading as we reach the end of the command without having a
proper warning that nothing was even attempted to be built.
This commit adds a warning when that happens, and leaves immediately
after.
* allowing to set shell env vars from a key/value map.
* tests
This new map will work alongside the `environment_vars` but it allows using a
datasource value seamlessly. At validation, and because `environment_vars` was
an array of strings containing `KEY=value`, using datsources would not work,
because these values are not known yet and would evaluate to `<unknown>`. With
this, the value and the key can be unknown and will validate correctly for
datasources.
* evaluateLocalVariables: modify code for readability and some (not benchmarked) perfs
* Make default input variable type the DynamicPseudoType
This should be the default, and avoids a panic. This type can represent situations where a type is not yet known. Its meaning is undefined in cty.
* do not take Empty types from default value
* Update types.variables.go

* Add variable interpolation support to hcp_packer_registry block
* Add tests for variable interpolation in hcp_packer_registry block
* Add variable interpolation support to the build block (#11425)
* Add simple test to build command
* add test for crash
* fix
* show more precise error message when parse of a provisioner fails
* Revert "fix"
This reverts commit fc88e89fbb.
* add better severity
This :
* allows to have a `build.dynamic` block
* add tests
* makes sure to show a correct message when a source was not found
* display only name of source (instead of a weird map printout)
* use a "Did you mean %q" feature where possible
Because dynamic blocks need all variables to be evaluated and available, I moved parsing of everything that is not a variable to "after" variables are extrapolated. Meaning that dynamic block get expanded in the `init` phase and then only we start interpreting HCL2 content.
After #10819fix#10657
This adds the new `required_plugins` block to be nested under the packer block.
Example:
```hcl
packer {
required_plugins {
aws = {
version = ">= 2.7.0"
source = "azr/aws"
}
azure = ">= 2.7.0"
}
}
```
For example on darwin_amd64 Packer will install those under :
* "${PACKER_HOME_DIR}/plugin/github.com/azr/amazon/packer-plugin-amazon_2.7.0_x5.0_darwin_amd64"
* "${PACKER_HOME_DIR}/plugin/github.com/hashicorp/azure/packer-plugin-azure_2.7.0_x5.0_darwin_amd64_x5"
+ docs
+ tests
* move maps of plugins back in core
* go mod vendor
* more fixes
* fix imports
* Update core_test.go
* fix build
* more fixes
* more fixes
* up vendors after fixing sdk
* Update post_processor_mock.hcl2spec.go
* Leave implementatino of MapOf in the sdk for plugi tests
Other wise use the interface
* go mod tidy
* add MapOfDatasource type too
