health

Quick health check across all services: container states + endpoint reachability, in a single compact table.

Arguments

None. Ignore $ARGUMENTS.

Steps

1. Run two checks in parallel (a SINGLE turn with multiple Bash calls):

   • Container states. Get a clean tabular list of all compose services and their current state:

     docker-compose ps --format "table {{.Service}}\t{{.State}}\t{{.Status}}"
     

   • Endpoint probes. Hit each public-facing endpoint with a short timeout and capture only the HTTP status. Run them concurrently in one shell:

     for url in <ENDPOINT_1> <ENDPOINT_2> <ENDPOINT_3> <ENDPOINT_4>; do
       code=$(curl -s -o /dev/null -w "%{http_code}" --max-time 3 "$url" || echo "TIMEOUT")
       echo "$url $code"
     done
     

2. Format a single combined report. Render two compact tables — containers first, endpoints second:

   containers:
     SERVICE          STATE    STATUS
     backend          running  Up 2 hours
     frontend         running  Up 2 hours
     mysql            running  Up 2 hours (healthy)
   
   endpoints:
     URL                                  CODE   NOTE
     http://localhost:3000                200    frontend ok
     http://localhost:8000                200    backend ok
     http://localhost:8000/api/health     200    api ok
   
   ✓ all green
   

3. Flag problems clearly. If anything is unhealthy:

   • Container in Exit, Restarting, or Created (but not running) → mark with ✗ and put it at the top of the containers table.
   • Endpoint returned TIMEOUT, 000, or any 5xx → mark with ✗.
   • Endpoint returned 4xx → mark with ⚠ (might be expected, e.g. 404 on root or unauthenticated 401).
