With the changes coming up for 1.11.0, we update the Packer
configuration docs so they describe the one way to load plugins, and the
two environment variables which can be set to change this behaviour.
Packer checks a number of directories for plugins upon initialization,
with the introduction of multi-component plugins and underlying changes
to the Packer SDK the ordering changed slightly. These changes update
the related documentation to reflect the new ordering, and adds a plugin
loading ordering section to the docs to help users discover how plugin
loading works.
Include in this change are updates to the PACKER_CONFIG_DIR environment
variables to reflect the XDG base directory specification used as the
default Packer configuration directory layout.
* Update website/content/docs/configure.mdx
This change updates the multi-component name to reflect the name
generated by the goreleaser configuration in packer-plugin-scaffolding.
It also adds a small call out about the SHA256SUM file that needs to be
present for binaries installed via `packer init` in case maintainers
want to test packer init locally without having to call out to GitHub.
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
