CircleCIでgolang1.6を使いたい際の設定

Circle CIでgolang1.6がまだ対応してないっぽいので超適当に書いた設定を晒す

dependencies:
  cache_directories:
    - ~/cache

  override:
    - |
      mkdir -p ~/cache/gopath
      cd ~/cache
      file=go1.6.linux-amd64.tar.gz
      if [ ! -e $file ]; then
        wget https://storage.googleapis.com/golang/$file
        tar xf $file
      fi

test:
  override:
    - |
      export GOPATH=$HOME/cache/gopath
      export GOROOT=$HOME/cache/go
      export PATH=$GOROOT/bin:$PATH
      export workdir=$GOPATH/src/github.com/user/project
      mkdir -p `dirname $workdir`
      ln -s $PWD $workdir 2> /dev/null || true
      cd $workdir
      go get ./...
      go test ./...
      # そのたもろもろ
