1.2 docker-compose.yml

version: '3'

services:
  jenkins:
    image: jenkins-jdk-maven:latest
    restart: unless-stopped
    container_name: jenkins
    user: root
    ports:
      - "8080:8080"
      - "5000:5000"
    volumes:

      - /root/.ssh/id_ed25519.pub:/root/.ssh/id_ed25519.pub

1.3 start_jenkins_server.sh

# 启动 jenkins 服务

# 构建
docker build -t jenkins-jdk-maven .

# jenkin 数据路径
JENKINS_HOME="/data/jenkins_home"

if [ ! -d "$JENKINS_HOME" ]; then
  echo "目录不存在: $JENKINS_HOME"
  mkdir -p "$JENKINS_HOME"
  echo "创建目录完成"
else
  echo "目录存在: $JENKINS_HOME"
fi

# 赋予权限
chown -R 1000:1000 "$JENKINS_HOME"

# 启动
docker compose up -d

二、启动

[root@localhost jenkins_script]# chmod +x start_jenkins_server.sh

[root@localhost jenkins_script]# ./start_jenkins_server.sh

三、查看密码

[root@localhost jenkins_script]# cat /data/jenkins_home/secrets/initialAdminPassword 
118b816e6ee74f689fcb5756a6ca69eb
[root@localhost jenkins_script]# 

四、检查jdk

[root@localhost jenkins_script]# docker exec -it jenkins /bin/bash
root@46c72f8cecb5:/# java -version
openjdk version "17.0.12" 2024-07-16
OpenJDK Runtime Environment Temurin-17.0.12+7 (build 17.0.12+7)
