dockcheck
A script checking updates for docker images without the need of pulling - then optionally auto-update chosen containers.
With the help of regctl. This is just a concept for inspiration, use with care.
Dependencies:
Running docker (duh) and compose, either standalone or plugin.
regctl by regclient (will ask to download regctl if not in PATH or PWD)

🪲 Squashed Bugs:
No options for running without updates or auto update.No filter to check only specific containers.Faulty registry checkups stopped the updates completely.No clear checks to skip containers producing errors.Multi-digest images didn't correctly check with registry, giving false positives on updates.Not working with filenames other thandocker-compose.ymlLists are not alphabetically sorted (due to stacks and other parameters)
🔨 Known issues
No granular choice of what to update (except initial name filter).- No detailed error feedback (just skip + list what's skipped) .
dockcheck_docker-run_ver.sh
Wont auto-update the containers, only their images. (compose is recommended)
Alternative version for people who use docker run and no composes.
docker run dont support using new images just by restarting a container.
Containers need to be stopped, removed and created again to run on the new image.
dupc_function.sh
Function to quickly check for updates on a single contianer or list of containers by name. Without the need of pulling.
Preferably placed in .bashrc or similar.
Example:
$ dupc ng
Updates available for local_nginx.
nginx_reverse is already latest.
Updates available for paperless-ng.
