The term “docker prune kubernetes” describes running the Docker prune inside a Kubernetes cluster. Bobcares, as a part of our Kubernetes Support offers solutions to every query that comes our way.

The “DOCKER PRUNE KUBERNETES”

We can use the command “docker prune” to clean up and remove certain Docker resources that are not in use. Over time, as networks, disks, and other resources are used with Docker, unwanted objects may gather and take up storage space on the system. We can recover this space by deleting these unnecessary resources with the docker prune.

Using the “docker prune kubernetes,” one can clean up any unnecessary Docker resources in a Kubernetes cluster. Here’s an overview of how it will function:

1. Initially, get access to the Kubernetes nodes that host Docker. The engine is usually present on each node.

2. Run the Docker prune on every node separately. Ansible or Kubernetes controllers are two examples of config management tools that can be used to run the code directly on the nodes.

3. In order to show the kinds of resources to prune, set up the Docker prune code with the necessary parameters. For e.g., we can get rid of any volumes, dangling images, networks, as well as the containers.

4. On each Kubernetes node, this command will locate and get rid off the designated kinds of unnecessary resources from the Docker runtime.

Conclusion

Our Tech team can routinely clear out unnecessary resources from all of the cluster’s nodes by using the Docker prune inside a Kubernetes cluster. This aids in maintaining an effective Kubernetes environment.
