首先安装gitlab runner

 

查看安装说明

sudo curl -L --output /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

# Give it permission to execute
sudo chmod +x /usr/local/bin/gitlab-runner

# Create a GitLab Runner user
sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

# Install and run as a service
sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
sudo gitlab-runner start

注册runner

sudo gitlab-runner register --url $GITLABURL --registration-token $REGISTRATION_TOKEN

[root@gitlab ~]# gitlab-runner register --url http://192.168.55.11/ --registration-token GR1348941iEsdsdq12f:%wea
Runtime platform                                    arch=amd64 os=linux pid=221844 revision=bd40e3da version=14.9.1
Running in system-mode.                            
                                                   
Enter the GitLab instance URL (for example, https://gitlab.com/):
[http://192.168.55.11/]: 
Enter the registration token:
[GR1348941iEsdsdq12f:%wea]: 
Enter a description for the runner:
[gitlab]: k8s                                  #任意输入
Enter tags for the runner (comma-separated):
k8s-git                                        #任意输入
Enter optional maintenance note for the runner:

Registering runner... succeeded                     runner=GR134894
Enter an executor: kubernetes, custom, parallels, shell, ssh, virtualbox, docker+machine, docker-ssh+machine, docker, docker-ssh:
shell                                           #此处可根据自己情况进行选择docker
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 

注册完成后可看到新创建的Runner

 完成runner创建后可进行cicd编辑

在使用shell模式时，需要在gitlab服务器上安装git及maven，在代码库的pom.xml上添加私有仓库地址，需要和maven下settings.xml相对应

<distributionManagement>

        <!--正式版本-->
        <repository>
            <!-- nexus服务器中用户名：在settings.xml中<server>的id-->
            <id>maven-releases</id>
            <!-- 这个名称自己定义 -->
            <name>Releases</name>
            <url>http://192.168.55.22/repository/maven-releases/</url>
        </repository>

        <!--快照版本 -->
        <snapshotRepository>
            <id>maven-snapshots</id>
            <name>Snapshot</name>
            <url>http://192.168.55.22/repository/maven-snapshots/</url>
        </snapshotRepository>

settingx.xml配置

gitlab-ci.yml配置内容，仅master分支触发

stages:
  - build

job_build:
  stage: build
  script:
    - echo "start mvn build!!!"
    - echo $CI_COMMIT_TAG
    - mvn versions:set -DnewVersion=$CI_COMMIT_TAG
    - mvn clean deploy 
  only:
    - master
  tags:
    - mvn              #此处为Runner的tag，可用于指定Runner
