Batch Update Docker Images
Usecase?
I have a number of Docker Images that I like to keep updated. This is a simple script which checks for updates with registry-1.docker.io/v2 & issues a docker pull if an update is found.
- Clone the repo
❯ git clone https://github.com/frost19k/BUDI- Install BUDI
❯ cd BUDI/
❯ pip3 install .❯ budi -f imageList.txt| Parameter | Description |
|---|---|
| -f --file | Input file containing docker image names (required) |
| -t --threads | Number of concurrent threads (default: 2) |
| -d --delete | Delete existing image after update (default: false) |
| -F --force | Froce remove image after update (default: false) |
| -v --version | Display version information |
- BUDI accepts a simple text file as input
- Each line must be an docker image of the form
repo/name:tag repo&tagare optional- For e.g.
❯ cat imageList.txt
bitnami/wordpress:6-debian-11
golang:1.17-alpine
kalilinux/kali-last-release
nginx:stable-alpine-perl
