Environment ready for Docker installation startup

Check whether the system kernel meets version 3.10 or above:

Uname-r

Upgrade the kernel package:

Yum update

Install Docker using yum:

Yum install docker

Start Docker:

Systemctl start docker

View the Docker version:

Docker-vJava environment installation

Use Docker to install the environment for Java 8:

Docker pull java:8Docker remote access configuration

Open the docker.service file:

Vim / lib/systemd/system/docker.service

Add a listening port:

ExecStart=/usr/bin/dockerd-current-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sockDocker restart

Reload the configuration file for Docker:

Systemctl daemon-reload

Restart Docker:

Systemctl restart docker

Check to see if there is a dockerd-current process:

Netstat-tulp

Use curl to see if the configuration of Docker takes effect:

Curl http://127.0.0.1:2375/infoIDEA configuration Docker

Open Docker under the path File- > Settings:

Configure the path address of Docker:

Project configuration

Configure the pom.xml file

Add the following configuration to the pom.xml file of the project:

Com.spotify docker-maven-plugin 1.0.0 build-image package build ${project.artifactId} latest ${project.baseDir} / src/main/resources http://192.168.6.66 : 2375 / ${project.build.directory} $ {project.build.finalName} .jar configuration Dockerfile file FROM java:8# mount directory VOLUME / tmpADD * .jar app.jar# exposes the port number EXPOSE 8083ENTRYPOINT ["java" "- Djava.security.egd=file:/dev/./urandom", "- jar", "/ app.jar"] Docker configures Maven packaging to generate Docker images

Use the clean and package commands in the Maven toolbar to package the project to generate a Docker image

Right-click on the generated Docker image and select Create Container to configure the Docker image. After the configuration is completed, click Run to start the Docker container:

The effect of launching the Docker container is as follows:

Access the project based on port name 8083 and project name oxford:

Http://127.0.0.1:8083/oxford Summary Linux Operation Command

View the status of the Linux firewall:

Service firewalld status

Turn off the Linux Firewall:

Service firewalld stopDocker operation command

Configure Docker Boot self-boot:

Systemctl enable docker

Stop the Docker service:

Systemctl stop docker

Start the Docker service:

Systemctl start docker

View all mirrors:

Docker images

Pull the image with the specified name:

#: tag is optional. Represents a label. Usually the version of the mirroring software. The default is latestdocker pull image name: tag

Delete the specified mirror:

Docker rmi image-id

View the running Docker container:

Docker ps

View all Docker containers, including running Docker containers and unrunning Docker containers:

Docker ps-a

Start the container:

Docker start container name / container ID

Stop the container:

Docker stop container name / container ID

Delete the container:

Docker rm Container ID

View the container log:

Docker logs container name / container ID

Runs the specified image in the specified Docker container:

#-- name means custom container name.-d means running docker run in the background-- name custom container name-d image name #-p indicates the container internal port docker run to which the host port is mapped-- name custom container name-d image name-p 8088 is above the name of the container.
