circleci-go

CircleCI builder image for Go projects. Now for Go module projects only. Reference driveclutch/circleci-go:glide in your project's Dockerfile to continue using a Glide-compatible version.

To migrate to Go modules:

• move work outside of $GOPATH if needed (Go modules deprecate $GOPATH)

• run go mod init github.com/DriveClutch/project-name to create a go.mod file (commit this)

• remove the glide.yaml / glide.lock files

• in your project's .circleci/config.yml file reference driveclutch/circleci-go:latest as the builder image and update the working directory to simply be /project-name (instead of being relative to the go path eg, go/src/github.com/DriveClutch/project-name)

• go build should download the dependencies and generate a go.sum file (also commit this)

• see more: https://blog.golang.org/migrating-to-go-modules

• to enable caching, add a step like this before the build step

  - restore_cache:
      keys:
        - some-prefix-{{ .Branch }}-{{ checksum "go.sum" }}
  

  and add a step like this after the build and test steps

  - save_cache:
      key: some-prefix-{{ .Branch }}-{{ checksum "go.sum" }}
      paths:
        - /go/pkg/mod/cache
  

• modify the working directory step to not be in the $GOPATH anymore

    working_directory: /src/<project name>

• add support for Go private repos as dependencies
