【Jenkins】持续集成和部署-蒲公英云

1.生成安全证书，放到/usr/local/jenkins/data里面

mkdir -p /opt/cert/docker
cd /opt/cert/docker
#逐行执行下面的脚本($HOST替换成你的域名)
openssl genrsa -aes256 -out ca-key.pem 4096
openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
openssl genrsa -out server-key.pem 4096
openssl req -subj "/CN=$HOST" -sha256 -new -key server-key.pem -out server.csr
# 配置白名单，推荐配置0.0.0.0，允许所有IP连接但只有证书才可以连接成功
echo subjectAltName = DNS:$HOST,IP:0.0.0.0 > extfile.cnf
openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out server-cert.pem -extfile extfile.cnf
openssl genrsa -out key.pem 4096
openssl req -subj '/CN=client' -new -key key.pem -out client.csr
echo extendedKeyUsage = clientAuth > extfile.cnf
openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem -extfile extfile.cnf
rm -v client.csr server.csr
chmod -v 0400 ca-key.pem key.pem server-key.pem
chmod -v 0444 ca.pem server-cert.pem cert.pem

2.安装docker

apt update
apt install docker.io

3.修改配置

vi /usr/lib/systemd/system/docker.service
# 注释掉其中的ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
# 添加如下
ExecStart=/usr/bin/dockerd \
--tlsverify --tlscacert=/opt/cert/docker/ca.pem  \
--tlscert=/opt/cert/docker/server-cert.pem \
--tlskey=/opt/cert/docker/server-key.pem \
-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
# 重启docker
systemctl daemon-reload && systemctl restart docker
# 测试2375端口，直接访问报错
curl https://域名:2375/info
# 指定证书访问成功
curl --insecure https://域名:2375/info --cert /opt/cert/docker/cert.pem --key /opt/cert/docker/key.pem --cacert /opt/cert/docker/ca.pem

4.安装gogs

docker pull gogs/gogs
docker run -d -p 10022:22 -p 3000:3000 --name=gogs --restart=always gogs/gogs

3000端口访问：

localhost换成公网ip:

接着登录注册、上传仓库：

5.安装jenkins

mkdir -p /usr/local/jenkins/data
chmod -R a+w /usr/local/jenkins/data/
docker pull jenkins/jenkins
docker run --privileged=true -u=root -itd --name jenkins -v /usr/local/jenkins/data:/var/jenkins_home/ -p 8080:8080 -p 50000:50000 --restart=always jenkins/jenkins

docker logs jenkins
# 输入密码

6.安装java和maven

# ca.pem cert.pem key.pem也移到这里来

7.配置jenkins（这块非常难）

先添加插件publish over ssh，不会可以百度，很简单。

1.项目根目录添加jenkins.sh

#!/bin/bash
    if docker ps | grep gateway; then
        docker stop gateway
        docker rm gateway
        docker rmi flow/gateway:latest
    fi
    if docker ps | grep auth; then
        docker stop auth
        docker rm auth
        docker rmi flow/auth:latest
    fi
    if docker ps | grep video; then
        docker stop video
        docker rm video
        docker rmi flow/video:latest
    fi
    if docker ps | grep userinfo; then
        docker stop userinfo
        docker rm userinfo
        docker rmi flow/userinfo:latest
    fi
    if docker ps | grep comment; then
        docker stop comment
        docker rm comment
        docker rmi flow/comment:latest
    fi

2.安装插件Publish Over SSH并全局配置

3.第一步当然是拷贝jenkins.sh到根目录下，并执行，目的是清除镜像和容器

4.执行打包镜像的命令

4.2023.4.3修改如下

mvn clean install
echo "开始构建Las Vegas的微服务群"
cd gateway
mvn docker:build
cd ../auth
mvn docker:build
cd ../video
mvn docker:build
cd ../userInfo
mvn docker:build
cd ../comment
mvn docker:build
echo "Las Vegas的微服务群构建完毕！"
cd ..
echo "开始更改文件"
cd gateway
