Cleaning up exited Docker containers which will free up disk space

Products

• Rally On-Premise

Issue/Introduction

When a docker container exits, it leaves behind its old files in the event that it is necessary to access the logs from that container

Over time, these containers will contribute to disk space usage.  As a maintenance task, one should periodically remove exited containers that are no longer needed.

This process may also be necessary if a support bundle is not being generated properly, for example if the support bundle is incomplete with only a README.md, or if the support bundle is not being generated in a timely manner.

Environment

Release : 2.0+

Component :  Docker

Resolution

Log into the services VM as ops

Run the following command:

$ sudo docker ps -a | grep Exited
