Packer Plugin Sdk

[](https://pkg.go.dev/github.com/hashicorp/packer-plugin-sdk/)

Packer Plugin SDK

This SDK enables building Packer plugins. This allows Packer's users to use both the officially-supported builders, provisioners, and post-processors, and custom in-house solutions.

Packer itself is a tool for building identical machine images for multiple platforms from a single source configuration. You can find more about Packer on its [website](https://www.packer.io) and [its GitHub repository](https://github.com/hashicorp/packer).

Packer CLI Compatibility

Packer v1.7.0 or later is needed for this SDK. Versions of Packer prior to that release are still compatible with third-party plugins, but the plugins should use the plugin tooling from inside earlier versions of Packer to ensure complete API compatibility.

Go Compatibility

The Packer Plugin SDK follows Go’s official [support policy](https://go.dev/doc/devel/release#policy). Refer to [`go.mod`](go.mod) for the minimum required Go version.

Getting Started

See the [Extending Packer](https://www.packer.io/docs/plugins/creation#extending-packer) docs for a guided tour of plugin development.

Documentation

See the [Extending Packer](https://www.packer.io/docs/plugins/creation#extending-packer) section on the Packer website.

Testing

The SDK embeds tests to ensure we don't introduce a regression in the future. Up to version 0.5.0 of the SDK, tests would be runnable with `make test` on their own but since we removed the `replace` statement for `go-cty` tests won't work out-of-the-box. Contributors will need to invoke `packer-sdc fix .` in order to fix the `go.mod` and `go.sum` files before running tests.

Please do not commit these changes, as adding this `replace` section to the `go.mod` file will make it impossible for dependents to run `go install` for `packer-sdc` afterwards.
