Golang和Gitlab持续集成

Question

I am close to achieve a complete (without testing stage) continuous integration in Gitlab with a Golang software.

It fails when I am trying to build the Docker image at the docker login step.

Here is my .gitlab-ci.yml :

stages:
  - build

variables:
  REGISTRY: registry.gitlab.com
  GO_PROJECT: mysoftware

build_golang_binary:
  image: golang:latest
  stage: build
  before_script:
    - mkdir -p ${GOPATH}/src/${GO_PROJECT}
    - cp -r ${CI_PROJECT_DIR}/* ${GOPATH}/src/${GO_PROJECT}/
    - cd ${GOPATH}/src/${GO_PROJECT}
    - go get
  script:
    - cd ${GOPATH}/src/${GO_PROJECT}
    - go build

build_docker_image:
  image: docker:latest
  stage: build
  script:
    - docker login $REGISTRY
    - docker build --no-cache -t ${REGISTRY}/me/${GO_PROJECT} .
    - docker push ${REGISTRY}/me/${GO_PROJECT}

Here is the error I am getting : $ docker login $REGISTRY Error: Cannot perform an interactive login from a non TTY device

I thought that the credentials would be provided into this CI process.. Apparently, they are not.

What is the best option to solve this ?

Answer 1

My answer assumes you're using GitLab.com for both the CI and Registry (based on registry.gitlab.com being in your .gitlab-ci.yml example above.

You can utilize several environment variables available in the GitLab CI job to authenticate to the GitLab Registry:

• docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY

The $CI_REGISTRY_PASSWORD is an ephemeral token that is only valid for the duration of your job. You can learn more in Authenticating to the Container Registry documentation.
