Starting the container.
Containers are instances or images and hence many containers can be made from one image. To create and run a container,a run command is given. Ps command shows the currently running containers while ps –a shows all the containers.
To view the container IP:
docker inspect
List of containers
The container are stored on the host at /var/lib/docker/container. If you list that location, you can get the list of all the container ids.
Port addressing
When a container is run, the application usually runs on the default port(80 for apache, for example). To run it on a particular port say, 700 we can write –p 700:80
Some of the other useful container commands are:
docker ps
lists all currently running containers.
docker ps -a
lists all containers
docker run --name cont_name -it <img_name> bash
Start a container interactively and make bash the entrypoint.
Example of starting an apache server container
Note that you should an index.html file at public-html already.Otherwise, there is nothing to show and while serving on browse, 404 error is thrown.
Output is something like(depending on your dockerfile)
