在一个 gitlab-ci 中使用多个跑步者

Question

我想用 2 个作业运行 CI 管道：

1. 作业将使用 docker-runner 启动 docker 映像并在 docker 内运行测试
2. 将在 ssh runner 下运行并在远程服务器上拉取代码。

有可能吗？

Answer 1

是的，这是可能的。您需要：

1. 向所需的 executor 注册两个 GitLab Runners（docker 和 shell），每个都有不同的标签（或者，至少其中一个带有构建标签)。
2. 在您的.gitlab-ci.yml 中为给定的job 声明一个特定的标签。

Shell runner 注册：

[root@jsc00mca ~]# gitlab-runner register
Running in system-mode.                            

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
https://example.com/
Please enter the gitlab-ci token for this runner:
1a2b3c
Please enter the gitlab-ci description for this runner:
[jsc00mca.example.com]: my-shell-runner
Please enter the gitlab-ci tags for this runner (comma separated):
shell
Whether to run untagged builds [true/false]:
[false]: 
Whether to lock the Runner to current project [true/false]:
[true]:
Registering runner... succeeded                     runner=ajgHxcNz
Please enter the executor: virtualbox, docker+machine, kubernetes, docker, shell, ssh, docker-ssh+machine, docker-ssh, parallels:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

Docker 跑步者注册：

[root@jsc00mca ~]# gitlab-runner register
Running in system-mode.                            

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
https://example.com/
Please enter the gitlab-ci token for this runner:
1a2b3c
Please enter the gitlab-ci description for this runner:
[jsc00mca.example.com]: my-docker-runner
Please enter the gitlab-ci tags for this runner (comma separated):
docker
Whether to run untagged builds [true/false]:
[false]: 
Whether to lock the Runner to current project [true/false]:
[true]:
Registering runner... succeeded                     runner=ajgHxcNz
Please enter the executor: virtualbox, docker+machine, kubernetes, docker, shell, ssh, docker-ssh+machine, docker-ssh, parallels:
docker
Please enter the default Docker image (e.g. ruby:2.1):
alpine:latest
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!

.gitlab-ci.yml

buildWithShell:
  stage: build
  tags:
  - shell
  script:
  - echo 'Building with the shell executor...'

buildWithDocker:
  image: alpine:latest
  stage: build
  tags:
  - docker
  script:
  - echo 'Building with the docker executor...'

Answer 2

是的，您可以从单个 gitlab-ci 管道触发不同/混合的运行器。

首先你应该在目标主机上注册一个shell runner并给它一个标签（截断）：

$ gitlab-runner register
...

Please enter the gitlab-ci tags for this runner (comma separated):
my_shell_runner
...
Please enter the executor: virtualbox, docker+machine, docker-ssh+machine, docker, docker-ssh, parallels, shell, ssh:
shell

在你的 gitlab-ci.yaml 中，这样的东西应该可以工作。 “测试”作业基于图像 NAME_OF_IMAGE 在 docker 容器中运行您的测试命令。

如果成功，“部署”作业会根据标签“my_shell_runner”选择您的 shell 运行器，并将执行运行器主机上脚本标签内的所有命令（截断）：

 test:
   stage: test
   services:
     - docker:dind
   tags:
     - docker-executor
   script:
     - docker run --rm NAME_OF_IMAGE sh -c "TEST_COMMAND_TO_RUN"

 deploy:
   stage: deploy
   tags:
     - my_shell_runner
   script:
     - COMMAND_TO_RUN
     - COMMAND_TO_RUN
     - COMMAND_TO_RUN
