How docker runs a project

1. Enter the directory where your project war is stored

Edit the Dockerfile file

vim Dockerfile

The content is as follows:

rom registry.docker-cn.com/library/tomcat

MAINTAINER heihezi heihezi@foxmail.com

COPY myproject.war /usr/local/tomcat/webapps

2. Build your own image

docker build -t myproject:latest .

As expected, the steps to build the image will be displayed. The last line is

Successfully built b3f6ac3157ae

and the last string is the image id. a part of.

You can run docker images at this time to view your own image information

3. Run your own docker container

docker run -d -p 8888:8080 myproject

Here -d is running in the background. -p is the specified port, and the following 8888:8080 is to map the 8888 port of the host to the 8080 port of docker. If the operation is successful, an id will be printed out

4. Access your own project

Check whether tomcat starts successfully

192.168.1.178:8888

Access the project (add project name)

192.168.1.178:8888/myproject
