This is an opinionated go project template to use as a starting point for new projects.

• Builds with GoReleaser
  • Automated with GitHub Actions
  • Signed with Cosign (providing you generate a private key)
• Linting with golangci-lint
  • Automated with GitHub Actions
• Builds with Docker
  • While designed to use goreleaser, you can still just run docker build
• Apple Notary Signing Support
• Opinionated Layout
  • Never use internal/ folder
  • Everything is under pkg/ folder
• Commits must meet Conventional Commits
  • Automated with GitHub Actions (commit-lint)
• Automatic Dependency Management with Renovate
• Automatic Semantic Releases
• Documentation with Material for MkDocs
• API Server Example
  • Uses Gorilla Mux (yes it's been archived, still the best option)
• Stubbed out Go Tests (note: they are not comprehensive)

• Uses init functions for registering commands globally.
  • This allows for multiple main package files to be written and include different commands.
  • Allows the command code to remain isolated from each other and a simple import to include the command.

This project is designed to build for multiple platforms, including macOS, Linux, and Windows. It also supports multiple architectures including amd64 and arm64.

The goreleaser configuration is set up to build for all platforms and architectures by default. It even supports pushing multi-architecture docker manifests by default. Some knowledge about GoReleaser's configuration is required should you want to remove these capabilities.

This makes use of a tool called quill. To make use of this feature you will need to have an Apple Developer account and be able to create an Developer ID certificate.

The workflow is designed to pull the necessary secrets from 1Password. This is done to keep the secrets out of the GitHub Actions logs. The secrets are pulled from 1Password if the event triggering the workflow is a tag AND the actor is the owner of the repository. This is to prevent forks from being able to pull the secrets and is an extra guard to help prevent theft.

GoReleaser is configured to always sign and notarize for macOS. However, it will not notarize if the build is a snapshot.

If configured properly, the binaries located within the archives produced by GoReleaser will be signed and notarized by the Apple Notary Service and will automatically run on any macOS system without having to approve it under System Preferences.

If you do not wish to use 1Password simply export the same environment variables using secrets to populate them. The QUILL_SIGN_P12 and QUILL_NOTARY_KEY need to be base64 encoded or paths to the actual files.

The following will build binaries in snapshot order.

goreleaser --clean --snapshot --skip sign

Note: we are skipping signing because this project uses cosign's keyless signing with GitHub Actions OIDC provider.

You can opt to generate a cosign keypair locally and set the following environment variables, and then you can run goreleaser --clean --snapshot without the --skip sign flag to get signed artifacts.

• COSIGN_PASSWORD
• COSIGN_KEY (path to the key file) (recommend cosign.key, it is git ignored already)

cosign generate-key-pair

1. Rename Repository
2. Generate Cosign Keys (optional if you want to run with signing locally, see above)
3. Update .goreleaser.yml, search/replace go-project-template with new project name, adjust GitHub owner
4. Update main.go,
5. Update go.mod, rename go project (using IDE is best so renames happen across all files)

The Dockerfile is set up to build the project and then copy the artifacts from the build into the final image. It is also configured to allow you to just run docker build directly if you do not want to use GoReleaser.

To make things easier and faster, the Dockerfile has a default build argument set to go-project-template. GoReleaser will pass the new project name down (if you update the .goreleaser.yml file) and the Dockerfile will use that instead.

However, it would be better longer term to update this argument in the file or remove it all together.

Signing happens via cosign's keyless features using the GitHub Actions OIDC provider.

In order for Semantic Releases and GoReleaser to work properly you have to create a PAT to run Semantic Release so it's actions against the repository can trigger other workflows. Unfortunately there is no way to trigger a workflow from a workflow if both are run by the automatically generated GitHub Actions secret.

1. Create PAT that has content write permissions to the repository
2. Create GitHub Action Secret
   • SEMANTIC_GITHUB_TOKEN -> populated with PAT from step 1
3. Done

The project is built to have the documentation right alongside the code in the docs/ directory leveraging Mkdocs Material.

In the root of the project exists mkdocs.yml which drives the configuration for the documentation.

This README.md is currently copied to docs/index.md and the documentation is automatically published to the GitHub pages location for this repository using a GitHub Action workflow. It does not use the gh-pages branch.

make docs-serve

OR (if you have docker)

docker run --rm -it -p 8000:8000 -v ${PWD}:/docs squidfunk/mkdocs-material
