Not sure it's working?

docker ps | grep mcp
937c97964e92   mcpgateway/mcpgateway:latest   "./run-gunicorn.sh"      53 seconds ago   Up 52 seconds (health: starting)                                               mcpgateway

Hm, always getting healthy on my side. Will investigate further

e23b192f19a2   mcpgateway/mcpgateway:latest   "./run-gunicorn.sh"   12 seconds ago   Up 12 seconds (healthy)   0.0.0.0:4444->4444/tcp, :::4444->4444/tcp   mcpgateway

Tested in VM as well and logs show healthy. Ran make docker and make docker-run

docker ps --filter name=mcpgateway --format "table {{.Names}}\t{{.Status}}"
NAMES        STATUS
mcpgateway   Up About a minute (healthy)
