Editor to share with you how to deploy the springboot project to docker based on idea. I hope you will get something after reading this article. Let's discuss it together.

Idea installs the docker plug-in

1. Installation

2. Configuration

Note: for docker to be accessible through port 2375, you need to configure docker

Vim / lib/systemd/system/docker.service

Modify as follows

3. Configure the container

Dockerfile file (for convenience here, put the Dockerfile file under the root directory)

FROM java:8VOLUME / tmpADD / target/sso_test-0.0.1-SNAPSHOT.jar sso_test.jarEXPOSE 9999ENTRYPOINT ["java", "- Djava.security.egd=file:/dev/./urandom", "- jar", "/ sso_test.jar"]

The format is FROM or FROM:.

The first instruction must be a FROM instruction. Also, if you create multiple mirrors in the same Dockerfile, you can use multiple FROM instructions (one for each mirror).

VOLUME

The format is VOLUME ["/ data"].

Create a mount point that can be mounted from a local host or other container, which is generally used to store databases, data that needs to be maintained, and so on.

ADD

The format is ADD.

This command copies the specified to the container. It can be a relative path to the directory where Dockerfile is located, a URL; or a tar file (which is automatically extracted to a directory).

EXPOSE

The format is EXPOSE [...].

Tell the port number exposed by the Docker server container for use by the interconnected system. When starting the container, the host will automatically assign a port to be forwarded to the specified port through-P _ ~ ~ Docker.

ENTRYPOINT

There are two formats:

ENTRYPOINT ["executable", "param1", "param2"] ENTRYPOINT command param1 param2 (executed in shell)

Configure the commands that are executed after the container starts and cannot be overridden by the parameters provided by docker run.

There can be only one ENTRYPOINT per Dockerfile, and when more than one is specified, only the last one takes effect.
