docker cleaning

Perfect — this output tells us exactly where your disk space is stuck 👍

🔍 What’s going on

• Images: 36.28 GB total → 33.66 GB reclaimable (92%)
• Build cache: 33.96 GB total → 31.51 GB reclaimable
• Containers: all active ❌ (don’t touch)
• Volumes: all in use ❌ (don’t touch)

👉 You can safely free ~65 GB without breaking running containers.

✅ SAFE cleanup (recommended for your state)

1️⃣ Clear Docker build cache (BIGGEST win)

docker builder prune -a -f

🧹 Frees ~31.5 GB

2️⃣ Remove unused images (not used by running containers)

docker image prune -a -f

🧹 Frees ~33.6 GB

✔ Running containers will NOT be affected
✔ Images used by active containers are kept

❌ DO NOT run these (for now)

docker container prune   # all containers are active
docker volume prune      # all volumes are in use

📊 Verify space freed

docker system df
df -h

You should see Docker usage drop dramatically.

🛡️ Extra safety check (optional)

See which images are actually in use:

docker ps --format "table {{.Image}}\t{{.Names}}"

🔁 Prevent this from happening again

Add a weekly cleanup cron (safe)

crontab -e

Add:

0 3 * * 0 docker builder prune -a -f && docker image prune -a -f

🧠 Pro tip (important for Tamashani)

Since you deploy often:

• Use multi-stage Docker builds
• Avoid latest tags
• Clean build cache after CI/CD deploys

If you want, paste:

docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}"

I’ll tell you which images are bloated and how to slim them down 🚀
