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.
Run this script will execute `generate_list.yml` playbook in kubespray root directory and generate four files,
all downloaded files url in files.list, all container images in images.list, jinja2 templates in *.template.
```shell
bash generate_list.sh
./generate_list.sh
tree temp
temp
├── files.list
├── generate.sh
└── images.list
0 directories, 3 files
├── files.list.template
├── images.list
└── images.list.template
0 directories, 5 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.
In some cases you may want to update some component version, you can declare version variables in ansible inventory file or group_vars,
then run `./generate_list.sh -i [inventory_file]` to update file.list and images.list.
