Naming Docker Swarm Services after their respective node name

As you said, swarm nodes get host's hostname as swarm node name (internally). That's perfectly correct for me.
After deploying some services with default setting, ps shows something like:
37bbf2b56dbf serviceBar.1.ngneetjtxwhm2eijfs1gvt60t

Grafana Cat Panel

Grafana Cat Panel

Recent studies have shown that a steady flow of cute kitten pictures can increase work productivity by up to 100% and boost general morale. Therefore every dashboard should provide a cat panel.

Paste this code in a "Text" Panel with html mode and enjoy.

nginx basic auth with different users for read/write

This nginx configuration allows to restrict access via different methods to separate users.

This is very useful for private docker registries, where you want every member of your team to be able to fetch Docker images, but only some users (admins and CI users) to push new images to the registry.


  • User write can use GET, POST, PUT, DELETE and everything else.
  • User read can only use GET and HEAD.
  • Anonymous users are denied access entirely.
