Container image collecting script for offline deployment
This script has two features:
(1) Get container images from an environment which is deployed online.
@ -19,3 +23,21 @@ Step(2) can be operated with:
```shell
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.
```shell
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.
