What are you using to update your Docker images?
You must log in or # to comment.
All my docker images are in code in Github.
Renovate makes a PR when there are image or helm chart updates.
ArgoCD sees the PR merge and applies to Kubernetes.
For a few special cases I use ArgoCD-image-updater.
Im using Komodo for deployong and auto updates.
I am really liking komodo so far. I need to understand how the builder works and I think it will be perfect for what I need.
After too many wild rides with Watchtower auto-nuking services, thanks to breaking changes (migrations, DB updates, deployment changes, etc), I switched to What’s Up Docker and pin the version for all of my containers.
WUD lets me know when something has an update, so I periodically go through their release notes and do the update(s) manually. Usually as simple as read the notes, changes version in compose, down (or pull), then “up -d”. But this approach has saved my bacon multiple times.
I’ve seen there are other solutions - of varying degrees of promises vs delivery - but most of my stuff is long term and stable. My approach maintains all that.
I generally don’t update automatically, I currently use WUD. It works fine for image checking and notifications and had no need to change it for now, but I am thinking of trying dockhand too.
In reality for me it’s German CERT sending me emails that my n8n is again out of date with tons of CVEs.
I’m thinking of using Dockcheck. It’s not a drop-in replacement for Watchtower, but you probably can wip up a quick systemd service to run it.
Never used it, but TugTainer. I use the fork of Watchtower and run it with
'--run-once' '--cleanup'. You can run it and let it update your containers as soon as an update is available, but I just like to run it manually.I use dockwatch, but not for automatic updates. I just update after reviewing the changelog and user reports.
Komodo.
A corn job that run pull on then up -d on my docker compose file.
