Fix how to get image ID on offline deployment (#7808)
Previously IDs of container images were gotten from tar files of container
images but that way was wrong. If multiple json files are contained in a
tar file, the script got multiple IDs and tried to pass these IDs on
`docker tag` command. Then the command was failed.

This updates the script to get image IDs from `docker image inspect` command
to fix this issue.
In addition, this adds a check a registry container exists already or not
before deploying registry container to avoid a container conflict failure.

manage-offline-container-images.sh

Container image collecting script for offline deployment

This script has two features: (1) Get container images from an environment which is deployed online. (2) Deploy local container registry and register the container images to the registry.

Step(1) should be done online site as a preparation, then we bring the gotten images to the target offline environment. Then we will run step(2) for registering the images to local registry.

Step(1) can be operated with:

manage-offline-container-images.sh   create

Step(2) can be operated with:

manage-offline-container-images.sh   register

generate_list.sh

This script generates the list of downloaded files and the list of container images by roles/download/defaults/main.yml file.

Run this script will generates three files, all downloaded files url in files.list, all container images in images.list, all component version in generate.sh.

bash generate_list.sh
tree temp
temp
├── files.list
├── generate.sh
└── images.list
0 directories, 3 files

In some cases you may want to update some component version, you can edit generate.sh file, then run bash generate.sh | grep 'https' > files.list to update file.list or run bash generate.sh | grep -v 'https'> images.list to update images.list.
