使用docker部署jenkins

1. 使用docker:dind镜像启动容器

docker network create jenkins

docker run --name jenkins-docker --detach \
  --privileged --network jenkins --network-alias docker \
  --env DOCKER_TLS_CERTDIR=/certs \
  --volume jenkins-docker-certs:/certs/client \
  --volume jenkins-data:/var/jenkins_home \
  --publish 2376:2376 \
  docker:dind --storage-driver overlay2

2. 构建jenkins docker镜像

2.1 jenkins Dockerfile

FROM jenkins/jenkins:2.409
USER root
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
  https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
  signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
  https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean docker-workflow"

2.2 根据Dockerfile构建镜像

docker build -t myjenkins-blueocean:2.409-1 .

3. 启动jenkins

docker run --name jenkins-blueocean --restart=on-failure --detach \
  --network jenkins --env DOCKER_HOST=tcp://docker:2376 \
  --env DOCKER_CERT_PATH=/certs/client --env DOCKER_TLS_VERIFY=1 \
  --publish 8080:8080 --publish 50000:50000 \
  --volume jenkins-data:/var/jenkins_home \
  --volume jenkins-docker-certs:/certs/client:ro \
  myjenkins-blueocean:2.409-1

获取密码

docker exec jenkins-blueocean  cat /var/jenkins_home/secrets/initialAdminPassword 

输出

17969ad0647c4b359fec026818a0a80e

4. 登录jenkins

打开浏览器 输入 http://${YOUR_SERVER_IP}:8080
