gopack

Build and publish a Go binary as a minimal OCI image

gopack uses your locally installed version of Go to cross-compile your application, building an OCI image with the resulting binary, and pushing your image to a remote repository or a locally running daemon. Docker not required.

Install

gopack can be installed using the command:

go install github.com/ryanfowler/gopack/cmd/gopack@latest

Go 1.18+ is required.

Usage

Use the gopack run command to build and publish an image. Although all flags are optional, some notable flags are:

• --base: image to use as the base (default: gcr.io/distroless/static:nonroot)
• --repository: repository to push the final image to (default: Go binary name)
• --platform: platform(s) to build the image(s) for (default: linux/amd64)
• --tag: tag(s) to push the image with (default: latest)
• --daemon: push the final image to a local daemon, instead of the remote repository (e.g. docker)

Using a custom base image

gopack run ./cmd/gopack -b myimage:tag

Pushing to a specific remote respository

gopack run ./cmd/gopack -r ghcr.io/OWNER/gopack

Building for multiple platforms

gopack run ./cmd/gopack -p linux/amd64 -p linux/arm64

Specifying tags

gopack run ./cmd/gopack -t latest -t 12345678

Push to a local daemon

gopack run ./cmd/gopack --daemon docker

Please run gopack run -h for more information about the available options.
