1. 安装 docker 和 docker-compose

首先是安装 docker:

# 在ubuntu内sudo apt install docker.io

复制代码

执行`sudo docker version`，查看 docker 的版本信息

Client: Version:           19.03.6 API version:       1.40 Go version:        go1.12.17 Git commit:        369ce74a3c Built:             Fri Dec 18 12:21:44 2020 OS/Arch:           linux/amd64 Experimental:      false
Server: Engine:  Version:          19.03.6  API version:      1.40 (minimum version 1.12)  Go version:       go1.12.17  Git commit:       369ce74a3c  Built:            Thu Dec 10 13:23:49 2020  OS/Arch:          linux/amd64  Experimental:     false containerd:  Version:          1.3.3-0ubuntu1~18.04.4  GitCommit:         runc:  Version:          spec: 1.0.1-dev  GitCommit:         docker-init:  Version:          0.18.0  GitCommit:

复制代码

然后配置 docker 的镜像源为国内，加速镜像下载。我这边用的是腾讯云内部的镜像源:

执行`sudo vim /etc/docker/daemon.json`，内容如下：

{   "registry-mirrors": [       "https://mirror.ccs.tencentyun.com"  ]}

复制代码

保存，然后重启 docker：

sudo systemctl daemon-reloadsudo systemctl restart dockersudo docker info

复制代码

然后安装 docker-compose:

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-composesudo chmod +x /usr/local/bin/docker-composesudo docker-compose version

复制代码

如果看到如下的返回，说明安装成功

docker-compose version 1.25.4, build 8d51620adocker-py version: 4.1.0CPython version: 3.7.5OpenSSL version: OpenSSL 1.1.0l  10 Sep 2019

复制代码

下一步是将当前用户加入到 docker 用户组里面，方便后续操作:

sudo gpasswd -a ${USER} docker

复制代码

退出当前连接，重新登录系统，执行`docker info`。如果能够正常输出，说明当前用户加入 docker 用户组成功。

Server: Containers: 0  Running: 0  Paused: 0  Stopped: 0 Images: 0 Server Version: 19.03.6 Storage Driver: overlay2  Backing Filesystem: extfs  Supports d_type: true  ......

复制代码

2. 启动 jenkins

首先是创建好 jenkins 的目录

mkdir app/jenkins/jenkins-data -pcd app/jenkins

复制代码

创建`docker-compose.yml`这个文件，内容如下：

version: '3'services:  jenkins-master:    #privileged: true    container_name: jenkins-master    image: jenkinsci/blueocean:1.23.0    restart: always    user: root    ports:      - '8080:8080'      - '50000:50000'    volumes:      - $PWD/jenkins-data:/var/jenkins_home      - /var/run/docker.sock:/var/run/docker.sock      - /etc/localtime:/etc/localtime:ro

复制代码

执行`docker-compose up -d`

复制代码

查看进程是否正常`docker ps`

CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                                              NAMES1ff69690f759        jenkinsci/blueocean:1.23.0   "/sbin/tini -- /usr/…"   27 seconds ago      Up 22 seconds       0.0.0.0:8080->8080/tcp, 0.0.0.0:50000->50000/tcp   jenkins-master

复制代码

此时,执行`docker logs -f jenkins-master`,查看 jenkins 私钥:
