Docker Storage Mounts and Best Practices

Short summary

This article covers three Docker storage mount types: volumes, bind mounts, and tmpfs mounts. Volumes are Docker-managed and best for persistent data; bind mounts map host directories directly into containers for development; tmpfs stores data in RAM for temporary or sensitive information. Choosing the right mount type keeps images lightweight and improves data management and security.

• •Docker volumes are the recommended approach for persistent, portable data managed by Docker
• •Bind mounts map host directories into containers, useful for development and live code updates
• •tmpfs mounts store data in RAM for temporary or sensitive data like credentials and cryptographic keys
