Docker(三) 通过gitlab部署CICD「建议收藏」

# gitlab-ce为稳定版本，后面不填写版本则默认pull最新latest版本
# 注意需要配置镜像加速器，不然会非常慢
docker pull gitlab/gitlab-ce

docker run -d -p 443:443 -p 80:80 -p 222:22 --name gitlab --restart always -v /opt/gitlab/config:/etc/gitlab -v /opt/gitlab/log:/var/log/gitlab -v /opt/gitlab/data:/var/opt/gitlab gitlab/gitlab-ce

# -d：后台运行
# -p：将容器内部端口向外映射
# --name：命名容器名称
# -v：将容器内数据文件夹或者日志、配置等文件夹挂载到宿主机指定目录

# gitlab.rb文件内容默认全是注释
vim /opt/gitlab/config/gitlab.rb

# 配置内容如下：

# 配置http协议所使用的访问地址,不加端口号默认为80
external_url 'http://192.168.6.21'

# 配置ssh协议所使用的访问地址和端口
gitlab_rails['gitlab_ssh_host'] = '192.168.6.21'
gitlab_rails['gitlab_shell_ssh_port'] = 222 # 此端口是run时22端口映射的222端口

# 重启gitlab容器
docker restart gitlab

docker exec -it gitlab bash # 进入容器内部
gitlab-ctl restart sidekiq
gitlab-ctl hup unicorn

#1.为了方便操作，请先进入到root权限
sudo su

#2.下载安装包文件
curl -L --output /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

#3.添加权限
chmod +x /usr/local/bin/gitlab-runner

#4.新建一个操作用户
useradd --comment 'gitlab-runner' --create-home gitlab-runner --shell /bin/bash

#5.安装
#注意： --working-directory 是runner实际执行目录，所有从service端发起的请求命令，都会到该目录下进行执行。
gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner

#6.启动
gitlab-runner start

yum install java-1.8.0-openjdk* -y

yum install git

# 安装docker略
usermod -aG docker gitlab-runner  # 保证可以使用docker
sudo -u gitlab-runner -H docker info # 验证是否有效

# 安装docker-compose  略

# 安装maven
yum -y install maven 
mvn -v  #查看maven版本

# 配置aliyun镜像
vim /etc/maven/settings.xml
# mirrors节点下添加（注意不能有tab键）
