使用docker配置Jenkins,gitlab

安装docker-ce

如果你之前安装过 docker，请先删掉:

yum remove docker docker-common docker-selinux docker-engine

下载repo文件:

wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo

把软件仓库地址替换为 TUNA:

sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

最后安装:

yum makecache fast
yum install docker-ce

查看docker版本:

docker version

安装docker-compose

下载docker-compose执行文件：

curl -L https://github.com/docker/compose/releases/download/1.17.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

验证安装结果：

docker-compose -v
docker-compose version 1.17.1, build 6d101fb

下载镜像文件

下载gitlab-ce:

docker pull gitlab/gitlab-ce:latest

下载sonarqube：

docker pull sonarqube:latest

下载jenkins:

docker pull jenkins:latest

查看下载的镜像:

docker images

sonarqube           latest              c1637bd4502f        2 weeks ago         934MB
jenkins             latest              3f08dc4f3f5d        3 weeks ago         809MB

启动容器

编写docker-compose.yml文件:

version: '2'

services:
  gitlab:
      image: gitlab/gitlab-ce:latest
      ports:
          - "443:443"
          - "80:80"
          - "2222:22"
      networks:
          - devops
      volumes:
          - /data/gitlab/config:/etc/gitlab
          - /data/gitlab/logs:/var/log/gitlab
          - /data/gitlab/data:/var/opt/gitlab

  jenkins:
      image: jenkins:latest
      ports:
          - "8080:8080"
          - "50000:50000"
      networks:
          - devops
      volumes:
          - /data/jenkins:/var/jenkins_home
          - /var/run/docker.sock:/var/run/docker.sock

  sonarqube:
      image: sonarqube:latest
      ports:
          - "9000:9000"
          - "9092:9092"
      networks:
          - devops

networks:
  devops:
    driver: bridge

创建gitlab容器挂载的目录结构,如果不是root权限启动,需要修改权限为777：

mkdir /data/gitlab/{config,logs,data} -p

创建jenkins容器挂载的目录:

 mkdir  /data/jenkins
 chmod 777 /data/jenkins

在docker-compose.yml相同目录下，启动gitlab：

docker-compose up -d gitlab

gitlab容器的启动时间较长，大概需要5分钟容器才能处于正常状态：

 docker ps
CONTAINER ID        IMAGE                     COMMAND             CREATED             STATUS                    PORTS                                                            NAMES
8b7d4085ee8b        gitlab/gitlab-ce:latest   "/assets/wrapper"   22 minutes ago      Up 22 minutes (healthy)   0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp, 0.0.0.0:2222->22/tcp   devops_gitlab_1

启动后，登录web界面，设置密码，默认用户名为root.
启动jenkins:

docker-compose up -d jenkins

查看启动状态：

 docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS                       PORTS                                                            NAMES
d919b9c60882        jenkins:latest            "/bin/tini -- /usr..."   5 minutes ago       Up 5 minutes                 0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp                 devops_jenkins_1

查看密码文件:

docker logs devops_jenkins_1

启动sonarqube:

docker-compose up -d sonarqube

查看启动状态：

docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS                       PORTS                                                            NAMES
