Docker 发布Jenkins

K_Unicode / 2023-08-01 / 原文

更新系统：
```
sudo apt update
sudo apt upgrade
```

安装必要的依赖：

sudo apt install apt-transport-https ca-certificates curl software-properties-common

添加Docker官方的GPG密钥：

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

添加Docker的APT源：

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian bullseye stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

更新APT软件包索引：
```
sudo apt update
```

安装Docker引擎：

sudo apt install docker-ce docker-ce-cli containerd.io

验证Docker是否成功安装：
```
sudo docker run hello-world
```
如果一切顺利，将会输出"Hello from Docker!"的信息。

如果出现apt update 失败需将apt源换成阿里源
文件在 /etc/apt/下

备份原来的文件

cp  /etc/apt/source.list /etc/apt/source.list_bk

2.将以下内容进行替换

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

运行以下 docker 命令安装Jenkins

sudo docker run \
  -u root \
  -it \
  -d \
  --name jenkins \
  -p 9000:8080 \
  -v /opt/docker/jenkins_home:/var/jenkins_home \
  -v /var/run/docker.sock:/var/run/docker.sock \
  jenkins/jenkins

将jenkins文件挂载在宿主机/opt/docker/jenkins_home目录下,将hudson.model.UpdateCenter.xml中的url换成 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json，并重启jenkins

cd /opt/docker/jenkins_home
sudo vim hudson.model.UpdateCenter.xml
替换 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
sudo docker restart jenkins

sudo docker exec -it jenkins bash
jenkins 容器中需要安装docker，按照以上安装docker 的命令安装，设置docker的daemon

vim /etc/docker/daemon.json

粘贴以下内容
{
  "registry-mirrors": [
    "https://registry.docker-cn.com"
  ],
  "insecure-registries": [
    "你的dockerhub-Ip:5000"
  ]
}

重启jenkins容器内的docker
