zim-tools | Various ZIM command line tools | Continuous Deployment library

You are trying to execute the zimDump in a container that has stopped. You can see that the container is stopped from the status Exited 0. The reasons is that the container doesn't initiate a daemon as it's entry point, rather it only provide the tools, so better approach would be to use run with --rm to run instance of the container during the execution of the command, and to delete the container when the execution has finished. Depending on the nature of the commands executed, you might need to mount local folders as volumes to the image so the commands in the image have access to the files you want to process.
