How is Dozzle deployed?

Standalone Deployment

📦 Dozzle version

v8.7.3

✅ Command used to run Dozzle

docker run \
  --name dozzle-log-viewer \
  --restart unless-stopped \
  -d \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -p 8080:8080 \
  --pull always \
  amir20/dozzle

🐛 Describe the bug / provide steps to reproduce it

We want to use Dozzle to monitor logs from containers managed by Dokku. When a Dokku app is deployed, it is started inside a container with a temporary name, must pass a health check, and then the container is renamed to the desired name.

Dozzle picks up the initial temporary container name as part of ContainerStart() but does not handle ContainerRename(), so after the Dokku app deployment is complete the Dozzle container name does not match the Docker name.

Please add support for ContainerRename() to stay in sync with Docker.

Today I learned there is such a thing as docker rename. If docker rename triggers an event then I can do this. I'll have to investigate.

Implemented and it is currently in master. Can be tested with amir20/dozzle:master. Give it a try. I plan to release something tomorrow if 👍🏼

Works great, thanks for the fast turnaround!
