k8s Gitlab CI/CD 之自动编译Docker镜像并推送到指定的Registry

环境介绍：

说明	节点	ip	系统
Gitlab Server	git.ds.com	10.0.1.179	CentOS 7.5.1804
Gitlab Runner		10.0.1.178	CentOS 7.5.1804
Docker Registry Harbor	harbor.ds.com	10.0.1.183	CentOS 7.5.1804

关于 gitlab server和Harbor的安装这里就表述了。

一、gitlab runner的安装 (gitlab 10版本的)

1、根据具体的系统环境下载对应的二进制执行文件

1 2 3 4 5 6 7 8

# Linux x86-64 sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64   # Linux x86 sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-386   # Linux arm sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-arm

通过下面的地址你可以找到左右版本的二进制文件

https://docs.gitlab.com/runner/install/bleeding-edge.html#download-any-other-tagged-release

2、给刚下载的二进制执行文件添加执行权限

1	sudo chmod +x /usr/local/bin/gitlab-runner

3、安装docker

1	curl -sSL https://get.docker.com/ | sh

4、创建一个gitlab ci用户

1	useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

5、将gitlab ci用户添加到docker运行用户的组里面

1	usermod -aG root gitlab-runner

由于我的docker是用root用户运行的所以我这边将gitlab-runner用户加到root的组里面了。

 

6、开始运行GitLab-Runner

1 2	gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner gitlab-runner start

二、注册Runners

1、打开gitlab页面找到runners的注册令牌

 

2、去gitlab runner的节点上做注册动作

1	gitlab-runner register

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20

[root@DS-VM-Node_10_0_1_178 ~]$ gitlab-runner register Running in system-mode.   Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/): http://git.ds.com Please enter the gitlab-ci token for this runner: Fx1jQzBW5ZJoxz157KEU Please enter the gitlab-ci description for this runner: [DS-VM-Node_10_0_1_178.dwhd.org]: Please enter the gitlab-ci tags for this runner (comma separated): myrunner_10_0_1_178_2 Whether to run untagged builds [true/false]: [false]: true Whether to lock the Runner to current project [true/false]: [true]: true Registering runner... succeeded                     runner=Fx1jQzBW Please enter the executor: docker-ssh+machine, kubernetes, docker-ssh, shell, virtualbox, docker+machine, docker, parallels, ssh: shell Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! [root@DS-VM-Node_10_0_1_178 ~]$

 

 

3、重启一下runner使之生效

1	gitlab-runner restart

4、去gitlab上检查
能发现到一个刚注册的runner

5、将这个runner指定到指定项目上去

 

三、测试

新建了一个gitlab项目。
