A simple docker demo with Spring Boot Project .

• cd docker

• docker build -t nginx:my .

• docker run -d -p 92:80 nginx:my

• docker ps . (find the container id , assume is d066ddb91228)

• docker stop d066ddb91228 .

• docker rm d066ddb91228

• docker rmi nginx:my (to rm all container , just use : docker rm -f $(docker ps -a -q))

• cd docker-webc

• mvn clean package

• docker build -t liumapp/docker-webc:v1.0.0 .

• docker run -d -p 8082:8082 liumapp/docker-webc:v1.0.0

• docker login (maybe you need my account access , but sorry for can not offerd)

• docker push liumapp/docker-webc:v1.0.0

• you can search liumapp/docker-webc on http://hub.docker.com

• first of all , you need have a ecs server(CentOS) & install docker .

  for how to install and use docker in centos :

   yum install docker
    
   systemctl start docker
       
   docker run hello-world
  

• install registry2(named distribution in Github)

    docker run -d -p 5000:5000 --restart=always --name registry2 registry:2
  

• change tag of local image :

    docker images (find your image , for me , it is liumapp/docker-webc)
    
    docker tag liumapp/docker-webc:v1.0.0 ${your server ip}:5000/liumapp/docker-webc:v1.0.0
  

• config the daemon.js , if you are using mac , you need config it in docker->preferences->daemon . and the info below :

      "insecure-registries" : [
        "${your-server-ip}:5000"
      ],        
  

• push project to private repository :

    docker push ${your server ip}:5000/liumapp/docker-webc:v1.0.0
  

• add maven-docker-plugin in docker-webc's pom (it should already have).

• cd docker-webc & mvn clean package docker:build

• first of all , you need download and install Docker Compose (for more details , plz read : https://docs.docker.com/compose/install/ )

  or you can just run ./docker/install-compose.sh , but you may get the "Operation timed out" exception .

  in this case , you need go to https://github.com/docker/compose/releases and check the latest version of docker-compose.

• use commond :

    docker-compose --version
  

  to check is installed .

• build docker-webd by docker-compose :

  cd docker-webd
  
  docker-compose up
  

• kill webd :

  docker-compose kill webd
  

• run install-docker.sh (this shell will build multy images in docker)

• docker-compose up

  or use docker-compose up -d to run as daemon .

• maybe you need restart weba & webb

• open your browser , and visit : http://localhost:2333/docker-webb/b or http://localhost:2333/docker-weba/a
