完成微服务多服务器远程发布
1）配置远程部署服务器
从Jenkins服务器拷贝公钥到docker2远程服务器
ssh-copy-id 192.168.195.182

系统配置->添加远程服务器

2）修改Docker配置信任Harbor私服地址

点击查看代码

{
  "registry-mirrors": ["https://zydiol88.mirror.aliyuncs.com"], 
  "insecure-registries": ["192.168.195.183:85"]
}

重启Docker

3）添加参数
多选框：部署服务器

最终效果：

4）修改Jenkinsﬁle构建脚本

        }

}

推送上传gitlab

5）编写deployCluster.sh部署脚本，放到两台生产服务器中
路径：/opt/jenkins_shell/deployCluster.sh

点击查看代码

#! /bin/sh
#接收外部参数
harbor_url=$1
harbor_project_name=$2
project_name=$3
tag=$4
port=$5
profile=$6

imageName=$harbor_url/$harbor_project_name/$project_name:$tag

echo "$imageName"

#查询容器是否存在，存在则删除
containerId=`docker ps -a | grep -w ${project_name}:${tag}  | awk '{print $1}'`

if [ "$containerId" !=  "" ] ; then
    #停掉容器
    docker stop $containerId

    #删除容器
    docker rm $containerId
 
 echo "成功删除容器"
fi

#查询镜像是否存在，存在则删除
imageId=`docker images | grep -w $project_name  | awk '{print $3}'`

if [ "$imageId" !=  "" ] ; then
      
    #删除镜像
    docker rmi -f $imageId
 
 echo "成功删除镜像"
fi


# 登录Harbor
docker login -u tom -p Abcd1234 $harbor_url

# 下载镜像
docker pull $imageName

# 启动容器
docker run -di -p $port:$port $imageName $profile

echo "容器启动成功"
