{"version":"1.0","type":"rich","title":"Backup/Save all Docker Images to a compressed file","description":"This visualization example shows a shell script that backs up every Docker image on the system to a compressed file. It demonstrates a practical workflow for system administration rather than a graphical chart. The script uses the `docker images` command to list images, filters out lines with \"none\" tags, and extracts image names with `awk`. It then loops through each image, transforms the name into a filename by replacing slashes and colons with hyphens, and saves the image using `docker save` piped through `pigz` for gzip compression with best quality. The process runs in real time as each image is processed sequentially.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-328426c0380fd9a5a7476c1a3e22c02f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
