Does it support multi-container Docker Compose setups?

Absolutely. The skill is specifically designed to work with Docker Compose, allowing it to inspect logs, networks, and configurations across multiple interdependent services.

How does it handle container health check failures?

It inspects the detailed health state metadata and suggests optimizations for intervals, timeouts, and start periods to ensure services have enough time to stabilize before checks begin.

How does this skill help with port conflicts?

It uses commands like lsof and netstat to identify the specific process blocking a port and suggests either terminating the process or remapping the service ports in your Docker Compose configuration.

Can it help with disk space issues caused by Docker?

Yes, it includes diagnostics for checking disk usage and provides safe commands to prune unused containers, images, and volumes to reclaim system space.

Can it fix permission denied errors in volumes?

Yes, it provides automated solutions for adjusting the user and group IDs in the compose file or executing ownership changes within the container to match host permissions.
