Today, I will talk to you about how to mirror the war package in Dockerfile. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

1. Install the tomcat image

Docker search tomcat, querying various image names of tomcat

Docker pull tomcat:8.5.43, install the image using docker pull, we want to download version 8.5.43 here.

two。 Write the Dockerfile file FROM tomcat:8.5.43WORKDIR / usr/local/tomcat/webapps/RUN rm-rf * ADD web/ .EXPOSE 8080CMD ["/ usr/local/tomcat/bin/catalina.sh", "run"]

FROM specifies the base image

WORKDIR specifies the working directory in the container

RUN rm-rf * delete the contents under webapps in the container

ADD web/. There is a war package in the web directory. Copy the war package to the working directory of the container.

EXPOSE declares that the runtime container provides a service port

CMD specifies the default startup command for the container main process

3. Build an image

Docker build-t cosmos_service.

Build the image from the Dockerfile file with the name cosmos_service

At this point, execute docker images, and you can see the image you just built.

4. Start the container

Docker run-d-name webapp-p 8088 purl 8080 cosmos_service:latest

-d indicates that the container runs in the background and returns the container ID-- name gives the container a name-p p1:p2 p1 means external access port p2 indicates that the last parameter of the port in the container is the name of the image and tag

Enter the container

Docker exec-it 5c9da02e552587d9b52883a4fa612854b919303222f5ad5af0eac3a61e372381 / bin/bash

The container ID returned by 5c9da02e552587d9b52883a4fa612854b919303222f5ad5af0eac3a61e372381 for run-d

After entering the container, you can view the war package deployment of tomcat.

5. Some general commands use the

Docker stop webapp stops running Container webapp

Docker start webapp starts the container webapp that has been stopped

Docker rm webapp delete container

Docker images view all mirrors

Docker rmi 5a4980b77ef4 deletes a mirror whose ID is 5a4980b77ef4
