Building multi architecture and multiplatform binaries with GoReleaser and Github Actions

github action GoReleaser multiarch multiplatform build

In order to build binaries for multiple architectures, we can use GoReleaser together with Github Actions so that they get built automatically when we create a release.

We are going to use as an example how binaries are built for kubectl's searchrule plugin. First we need to configure GoReleaser using the .goreleaser.yaml file:

project_name: kubectl-searchrule builds:  - goos:  - linux  - windows  - darwin  goarch:  - amd64  - arm64  main: ./rule-lookup.go  binary: kubectl-searchrule  env:  - CGO_ENABLED=0  - >-  {{- if eq .Os "darwin" }}  {{- if eq .Arch "amd64"}}CC=o64-clang{{- end }}  {{- if eq .Arch "arm64"}}CC=aarch64-apple-darwin20.2-clang{{- end }}  {{- end }}  {{- if eq .Os "windows" }}  {{- if eq .Arch "amd64" }}CC=x86_64-w64-mingw32-gcc{{- end }}  {{- end }}  {{- if eq .Os "linux" }}  {{- if eq .Arch "arm64" }}CC=aarch64-linux-gnu-gcc{{- end }}  {{- end }}  ignore:  - goos: darwin  goarch: 386  - goos: linux  goarch: arm  goarm: 7  - goarm: mips64  - gomips: hardfloat  - goamd64: v4

While this file instructs GoReleaser what to do, we'll need to create a Github Action workflow to tell it when to do it.

Using the folowing file in .github/workflows/releaser.yaml we are telling it how to build it using GoReleaser when a tag is pushed that matches the configured regex:

name: Release CLI on:  push:  tags:  - 'v[0-9]+.[0-9]+'  jobs:  release-cli:  name: Release CLI  runs-on: ubuntu-latest  steps:  - name: Checkout repository  uses: actions/checkout@v3  - name: Set up Go  uses: actions/setup-go@v4  with:  go-version: 1.19.x  - name: Run GoReleaser  uses: goreleaser/goreleaser-action@v4  with:  distribution: goreleaser  version: latest  args: -f .goreleaser.yaml release --clean  env:  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}  - name: Upload assets  uses: actions/upload-artifact@v3  with:  name: kubectl-searchrule  path: dist/*  if-no-files-found: error

Since we are using the actions/upload-artifact action, the resulting files will be uploaded as an asset in the releases page.
