Migrate Docker Containers to a New Server

Migration · 03.02.2025

Method 1: docker save / docker load

docker save myapp:latest | gzip > myapp.tar.gz
scp myapp.tar.gz root@NEW_SERVER:/tmp/
docker load < /tmp/myapp.tar.gz

docker run --rm -v myapp_data:/data -v $(pwd):/backup   alpine tar czf /backup/vol.tar.gz -C /data .

💡 For production, use a Docker Registry to push/pull images instead of save/load.
