GitlabCI

How it works (CI/CD process overview)

• Ensure you have runners available to run your jobs. GitLab SaaS provides runners, so if you’re using GitLab.com, you can skip this step.

If you don’t have a runner, install GitLab Runner and register a runner for your instance, project, or group.

• Create a .gitlab-ci.yml file at the root of your repository. This file is where you define your CI/CD jobs.

FAQ

1. Git Submodule - Permission Denied

• 错误描述(类似如下)：

$ git submodule update --init --recursive
Submodule 'lib/urlgrabber' (git@gitlab.colynn.com:linux/urlgrabber.git) registered for path 'lib/urlgrabber'
Cloning into 'lib/urlgrabber'...
Host key verification failed.
fatal: Could not read from remote repository.

• 解决方案： 方案1）使用相对路径：I had to change the paths in .gitmodules to relative

[submodule "lib/urlgrabber"]
        path = lib/urlgrabber
-       url = git@gitlab.deif.com:linux/urlgrabber.git
+       url = ../../linux/urlgrabber.git

方案2）通过前置脚本修改git config 替换掉git@gitlab.colynn.com:linux/urlgrabber.git

a. 通过为gitlab-ci.yml添加before_script的方式实现替换

before_script:
  - git config --global --add url."https://${GITLAB_USERNAME}:${GITLAB_TOKEN}@gitlab.colynn.com/linux/urlgrabber.git".insteadOf "git@gitlab.colynn.com:linux/urlgrabber.git"

b. 通过runner的配置文件，添加pre_clone_script的方式实现替换

  pre_clone_script="git config --global --add url.\"https://${GITLAB_USERNAME}:${GITLAB_TOKEN}@gitlab.colynn.com/linux/urlgrabber.git\".insteadOf \"git@gitlab.colynn.com:linux/urlgrabber.git\"\n"
