Idea one-click remote deployment springboot to Docker

Idea is a Java development tool, springboot Java ecosystem is the most popular micro-services framework, docker is among the most fire container technology, they combine what would be the chemistry of it?

First, the development of the former ready

1. Docker installation can refer https://docs.docker.com/install/

2. Configure docker remote connection port

  vi /usr/lib/systemd/system/docker.service
复制代码

Found ExecStart , the last position -H TCP: //0.0.0.0: 2375 , as shown in FIG.

3. Restart docker

 systemctl daemon-reload
 systemctl start docker
复制代码

4. open ports

firewall-cmd --zone=public --add-port=2375/tcp --permanent  
复制代码

5. Idea install the plug, reboot

6. Connect remote docker

(1) Edit Configuration

(2) Fill remote docker address

(3) successful connection, the container will be listed and remote mirroring docker

Second, new projects

1. Create a project springboot

Program structure.

(1) pom configuration file

(2) Create a docker directory under src / main directory, file and create Dockerfile

FROM openjdk:8-jdk-alpine
ADD *.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
复制代码

(3) create a file in the resource directory application.properties

logging.config=classpath:logback.xml
logging.path=/home/developer/app/logs/
server.port=8990
复制代码

(4) Create a file DockerApplication

@SpringBootApplication
public class DockerApplication {
    public static void main(String[] args) {
        SpringApplication.run(DockerApplication.class, args);
    }
}
复制代码

(5) create DockerController file

@RestController
public class DockerController {
    static Log log = LogFactory.getLog(DockerController.class);

    @RequestMapping("/")
    public String index() {
        log.info("Hello Docker!");
        return "Hello Docker!";
    }
}
复制代码

(6) increase the allocation

Command interpreter
Image tag: Specifies the image name and Tag , image name Docker-Demo , Tag is 1.1
the Bind the ports: Binding host port to the interior of the container port. Format [host port]: [vessel internal port]
the Bind mounts: The host directory linked to the interior of the container into the directory. Format [host Catalog]: [vessel internal directory]. This project will log springboot print container / home / developer / app / logs / after the directory, will host directory is mounted to the container internal directory, the log will persist outside of the container host directory.
