1.创建runner容器

mk@mk-pc:~/桌面$ docker run -di --name my-runner --net my-gitlab-net gitlab/gitlab-runner:latest
addc6e08521a6f707494c7a05e63670331c76baaf261282bdd17e2e24268583b

2.配置runner和gitlab做一个关联

root@addc6e08521a:/# gitlab-runner register
Runtime platform                                    arch=amd64 os=linux pid=262 revision=4b9e985a version=14.4.0
Running in system-mode.                            
                                                   
Enter the GitLab instance URL (for example, https://gitlab.com/):
http://192.168.88.2/
Enter the registration token:
mqL7CpxduBkV55pEwo7A
Enter a description for the runner:
[addc6e08521a]: my first runner
Enter tags for the runner (comma-separated):
dockercicd
Registering runner... succeeded                     runner=mqL7Cpxd
Enter an executor: docker, parallels, ssh, custom, shell, virtualbox, docker+machine, docker-ssh+machine, kubernetes, docker-ssh:
docker
Enter the default Docker image (for example, ruby:2.6):
app
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 
root@addc6e08521a:/# 

3.编写流水线文件

.gitlab-ci.yml

stages:
  - build
  - deploy

build:
  stage: build
  tags:
    - build
  only:
    - dev
  script:
    - echo "mvn clean"
    - echo "mvn install"

deploy:
  stage: deploy
  tags:
    - deploy
  only:
    - dev
  script:
    - echo "java -jar  dxxx"

运行流水线
