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

环境介绍：

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

# 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

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

3、安装docker

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

4、创建一个gitlab ci用户

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

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

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

gitlab-runner register

[[email protected]_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!
[[email protected]_10_0_1_178 ~]$

3、重启一下runner使之生效

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

为了写文章我这次新建了一个gitlab项目。

[[email protected]_10_0_1_178 /data]$ git clone http://git.ds.com/lookback/docker-nginx.git
正克隆到 'docker-nginx'...

2、配置项目runner的变量

3、配置.gitlab-ci.yml文件

[[email protected]_10_0_1_178 /data/docker-nginx]$ cat .gitlab-ci.yml
# This file is a template, and might need editing before it works on your project.
# Official docker image.

stages:
  - build_image
  - push_image

before_script:
  - docker info
  - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY

build_image:
  stage: build_image
  script:
    - docker build --pull -t "$CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG" .

push_image:
  stage: push_image
  script:
    - docker push "$CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG"
    - docker rmi "$CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG"

[[email protected]_10_0_1_178 /data/docker-nginx]$ git add .
