GoReleaser

GoReleaser builds Go binaries for several platforms, creates a github release and then push a homebrew formulae to a repository. All that wrapped in your favorite CI.

This project adheres to the Contributor Covenant code of conduct. By participating, you are expected to uphold this code. Please report unacceptable behavior to root@carlosbecker.com.

How it works?

The idea started with a simple shell script, but it quickly became more complex and I also wanted to publish binaries via homebrew.

So, the all-new goreleaser was born.

Usage

Create a goreleaser.yml file in the root of your repository. A minimal config would look like this:

repo: user/repo
binary_name: my-binary

You may then run releaser at the root of your repository:

curl -s https://raw.githubusercontent.com/goreleaser/get/master/latest | bash

For that to work, you need to export a GITHUB_TOKEN environment variable with the repo scope selected. You can create one here.

GoReleaser uses the latest Git tag of your repository, so you need to create a tag first.

This will build main.go as my-binary, for Darwin and Linux (amd64 and i386), archive the binary and common files as .tar.gz, and finally, publish a new github release in the user/repo repository with archives uploaded.

Homebrew

To push a basic formulae a homebrew tap repo, just add a brew section:

repo: user/repo
binary_name: my-binary
brew:
  repo: user/homebrew-tap
  folder: optional/subfolder/inside/the/repo
  caveats: "Optional caveats to add to the formulae"

Build customization

Just add a build section

repo: user/repo
binary_name: my-binary
build:
  main: ./cmd/main.go
  ldflags: -s -w
  oses:
    - darwin
    - freebsd
  arches:
    - amd64

• oses and arches should be in GOOS/GOARCH-compatible format.
• -s -w is the default value for ldflags.

Archive customization

You can customize the name and format of the archive adding an archive section:

repo: user/repo
binary_name: my-binary
archive:
  name_template: "{{.BinaryName}}_{{.Version}}_{{.Os}}_{{.Arch}}"
  format: zip
  replacements:
    amd64: 64-bit
    386: 32-bit
    darwin: macOS
    linux: Tux

• Default name_template is {{.BinaryName}}_{{.Os}}_{{.Arch}}
• Valid formats are tar.gz and zip, default is tar.gz
• By default, replacements replace GOOS with uname -s values and GOARCH with uname -m values. They keys should always be in the GOOS and GOARCH form.

Add more files

You might also want to change the files that are packaged by adding a files section:

repo: user/repo
binary_name: my-binary
files:
  - LICENSE.txt
  - README.md
  - CHANGELOG.md

By default GoReleaser adds the binary itself, LICENCE*, LICENSE*, README* and CHANGELOG*.

ldflags (main.version)

GoReleaser already sets a main.version ldflag, so, in you main.go program, you can:

package main

var version = "master"

func main() {
  println(version)
}

And this version will always be the tag name.

Wire it with travis-ci

You may want to wire this to auto-deploy your new tags on travis, for example:

after_success:
  test -n "$TRAVIS_TAG" && curl -s https://raw.githubusercontent.com/goreleaser/get/master/latest | bash

What the end result looks like

The release on github looks pretty much like this:

And the homebrew formulae would look like:

class Release < Formula
  desc "Deliver Go binaries as fast and easily as possible"
  homepage "https://github.com/goreleaser/releaser"
  url "https://github.com/goreleaser/releaser/releases/download/v0.2.8/release_Darwin_x86_64.tar.gz"
  version "v0.2.8"
  sha256 "9ee30fc358fae8d248a2d7538957089885da321dca3f09e3296fe2058e7fff74"

  def install
    bin.install "release"
  end
end
