Docker Communication With Networking Components Failed How To Properly Deal
Docker Communication With Networking Components Failed Update Inside Of

The docker ps command only shows running containers, not all containers.

You may encounter typos, issues with runtime libraries and modules, naming collisions, or issues when communicating with other containers.

Before we dive in, lets clarify the difference between images and containers.

Its what you ship and share through Docker Hub or your private registry.

This generally means that if you got to a certain step, then all of the previous steps completed successfully.

Create a dockerimage directory in your home directory, and use nano or your favorite editor to create a Dockerfile in that folder.

Can you spot it Try to build an image from this file to see how Docker handles a bad command.

In this case it was our intentional typo: we have aapt-get instead of apt-get.

But that also meant that the previous step executed correctly.

The base image comes with cached metadata, such as repositories and lists of available packages.

You may occasionally experience some cache issues when the live repositories youre pulling data from have changed.

The process also completes much more quickly because the previous steps were cached.

After this operation, 10.4 MB of additional disk space will be used.

If you run into issues installing or updating packages inside the container, run apt-get clean apt-get update inside of the container.

Now lets look at problems that may arise when running containers from those images.

A naming collision is where you try to create a container that has the same name as a container that already exists on your system.

Docker Communication With Networking Components Failed How To Properly Deal

Lets explore how to properly deal with naming, renaming, and deleting containers in order to avoid collisions.

You can see all of the running containers and their corresponding names by running the docker ps command on the Docker host, outside of the running container.

Letting Docker assign a name to your container is fine in very simple cases, but can present significant problems; when we deploy we need to name containers consistently so we can reference them and automate them easily.

The name pythonbox is already in use by container 80a0ca58d6ecc80b305463aff2a68c4cbe36f7bda15e680651830fc5f9dda772.

You have to remove (or rename) that container to be able to reuse that name.

Containers are a little more complicated because you cant overwrite a container that already exists.

Its not running, but its still available in case you want to start it up again.
