Fix how to get image ID on offline deployment ()
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.

Offline deployment

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.
