How do I start a docker container? There are usually two ways for docker to add mapped ports to a running container.

Method one

Docker commit docker run-p containerid

Use the above command to create a new image file, and the run-p parameter opens the new port, which is not convenient to use in practice.

Method two

Modify the iptables rules on the host (host) to open the response port of the container; refer to the commands on the network

Iptables-t nat-A DOCKER-p tcp-dport 8080-j DNAT-- to-destination 172.17.0.2 DOCKER 8080

When we create a nginx image and start nginx, we can only access the nginx URL in the inner area of the container. Therefore, in order to be accessible outside the container, the port needs to be exposed, and the port inside the container needs to be mapped out.

There are four forms of docker container exposure ports:

1.-p

Maps the specified container port to a random port of all host addresses

2.-p:

Map the container port to the specified host port

3.-p::

Map the container port to the random port of the host-specified ip

4.-p:

Map the container port to the specified port of the specified host ip

The above is how to start the docker container. Have you learned the knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
