How does the host access the program in docker

Requirements:

1: Access the application in docker locally

2: Other machines access the application in docker

3: DockerB access the application in dockerA

Known environment:

Host IP: 192.168.220.123
Container A has been started, IP: 172.17.0.2, Tomcat has been started, and the port is 8080.

Access the application in dockerA:

curl http://localhost:8080/ #当前docker curl http://172.17.0.2:8080/ #当前docker和docker所在的主机

There are two problems here:

1: Other hosts How to access this application?

2: What should I do if the ip changes after restarting docker? (IP is automatically assigned after docker is started)

Docker provides port mapping function, add the -p parameter when starting docker, map port: container application port

docker run -d -p 58080:8080 aa79

Access the application in dockerA:

curl http://localhost:8080/ #当前docker curl http://172.17.0.2:8080/ #当前docker和docker所在的主机 curl http://192.168.220.123:58080 #其他主机/其他docker
