If you have installed the Nova applications successfully in the past, subsequent reinstallation may result in one or more error messages. Simple steps for resolving these errors are described below:
Error: failed to remove one or more images
This issue occurs when one or more Docker containers reference the image being removed. To address this issue:
- Find out which containers reference the image by running: docker ps – a
- Remove the Docker containers one by one using this command: docker rm value
…where value is the either the “Container ID” or the “Name” in the table resulting from Step 1.
The following table contains a list of the two Docker commands used to resolve the issue above, as well as other useful commands.
|docker images||To view a list of installed Docker images.|
|docker rmi value||To remove a particular Docker image, where value is the “Image ID.”|
|docker ps K/font>||To view a list of Docker containers that are currently running.|
|docker ps -a||To view a complete list of Docker containers.|
|docker rm value||To remove a particular Docker container, where value is the “Container ID” or the “Name.”|
