# 对外端口
EXPOSE 10140

Build

clean package -Dmaven.test.skip=true

Post Steps

IMAGE_NAME="inner.meeno.net:5000/chemical:1.0"

# 进入项目
echo $PWD
cd /var/lib/jenkins/workspace/chemical_test/


# docker build
sudo docker build -t $IMAGE_NAME .

# push docker registry
sudo docker push $IMAGE_NAME

# success
echo 'push docker registry success'

目标服务器上配置可以使用 docker私有仓库

    echo '{ "insecure-registries":["xxx.xxx.xxx.xxx:5000"] }' > /etc/docker/daemon.json
    systemctl restart docker

构建后操作

Post Steps -> Execute shell script on remote host using ssh

command:

docker pull inner.meeno.net:5000/chemical:1.0

docker rm -f chemical_server

docker run -d -p 10140:10140 --name chemical_server inner.meeno.net:5000/chemical:1.0

查看是否部署成功

docker logs -f --tail 100 chemical_server
