Docker部署jenkins

先删除系统docker相关的依赖

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

安装docker相关依赖

yum install -y yum-utils

配置docker镜像地址

yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7  containerd.io-1.4.6

创建docker目录，并配置

mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://w6rlizew.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF

启动和关闭docker命令：

systemctl start docker
systemctl enable docker

修改主机名，关闭和启动防火墙

hostnamectl set-hostname k8s-master && bash #修改主机名
systemctl stop firewalld
systemctl disable firewalld

配置JDK和Maven

cd /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_371
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
export MAVEN_HOME=/usr/local/maven/apache-maven-3.6.3
export PATH=${MAVEN_HOME}/bin:${JAVA_PATH}:${PATH}

## 执行命令
source /etc/profile

使用docker操作jenkins

docker start jenkins  ## 开启jenkins
docker stop jenkins  ## 停止jenkins
docker rm jenkins ## 删除jenkins镜像
## 运行jenkins
docker run -d -uroot -p 8080:8080 -p 50000:50000 -p 8888:8888 --name jenkins -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):/usr/bin/docker -v /data/jenkins/jenkins:/var/jenkins -v /data/jenkins/jenkins_home:/var/jenkins_home -v /etc/localtime:/etc/localtime -v /usr/local/jdk-11.0.19:/usr/local/jdk-11.0.19 -v /usr/local/maven/apache-maven-3.6.3:/usr/local/maven/apache-maven-3.6.3 -v /etc/profile:/etc/profile jenkins/jenkins
