Hi 👋 to all my new followers 😇
I will try to give Bluesky a new chance and noticed a lot of new people following me. Thanks for that 😇
Most of the stuff that I post will be about Java and CNCF-related technologies (and conferences around it).
Looking forward to interact!

You deploy across clouds like it’s second nature. Docker listens, Kubernetes obeys, and somehow it all just works.

Since I was called out in person during the talk I should probably share it, too :-)
Jokes aside. This talk is an excellent reference for @graalvm.org and you all should watch it!

I had so much fun doing this @graalvm.org deep dive at @amsterdam.voxxeddays.com!
It covers everything you need to know to use Native Image:
✅ Migration
✅ Using libraries
✅ Performance
✅ Containerization
✅ Security
✅ Monitoring
✅ Future projects

Very interesting talk if you're building container images - especially for the JVM. I had not really explored buildpacks for this. Definitely gave me some things to think about
Here is my updated YT video about Java Container Builds: www.youtube.com/watch?v=HFhI...
Thanks a lot @cschuszter.bsky.social for providing an instant fix :-)

Good luck to the team - it’s a neat project!
I haven’t used other CI/CD/orchestrators in a long while, save for basic GH actions. I wonder if the CI world has caught up to the good ideas Concourse brought to the table.
