How to see docker image id
This article describes why latest is bad. For me, in this theoretical example. An image I was using introduced breaking changes. This is fine, since they tagged the new releases as version 2. But, only if I was actually using a specific image version and not latest would this be okay. Latest is latest. So the latest that was version 1, now turned into version 2. And everything broke. Now that you will never use latest again, you could still have a problem.
All those docker containers you have running are using images with the :latest tag. How do you find what version latest was?
Trick 1 Check the labels on your image. This is is used for the most of the container operations like stop, clone, connect etc. IMAGE column show the base image used to create related container. PORTS columns shows the redirected ports and related network configuration. NAME column shows the human readable name of the container. If it is not given explicitly docker engine assign random name. List Images As we know docker containers are created from previously pulled and stored images.
Images contains file system of the containers. We can list locally avaible images with the -image sub command.
Show Containers Logs Container will create docker engine related logs while running and operations. These log can be seen without searching them in directories with simple logs command.
Docker network explained First, let's understand how the Docker network works. For that we are going to focus on the default bridge network.

External access is granted by exposing ports to how to see docker image id. Bridge networks are used when your applications run in standalone containers that need to communicate. In the picture above db and web can communicate with each other on a user created bridge network called mybridge. We will ignore the other two, and use the bridge network when we get to the examples. And each network is created with a default subnet mask, using it as a pool later on to give away the IP addresses.
