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.
| Script | Definition |
|---|---|
| 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.” |
