1. Bad image name or label: You need to specify the correct image name and label when running the Docker container. If the specified picture name or label is wrong, Docker cannot find the corresponding picture, resulting in the error "No picture found". At this point, you need to check whether the mirror name and label are correct.
2. Image does not exist or is not downloaded: If the specified image does not exist or is not downloaded, Docker will also get an "image not found" error. At this time, you need to use the "dockerpull" command to download the corresponding image.
3.Docker daemon is not started: If Docker daemon is not started, Docker cannot find the mirror, resulting in the error "Mirror not found". At this point, you need to start the Docker daemon.
4. Access rights of the Docker mirror warehouse: If the Docker mirror warehouse needs to log in or has limited access rights, you need to provide correct login information or access rights when running the Docker container.
