tags: learning linux docker

content

• volume is a way to persist and share container data across lifecycles
• it’s basically a way to store data outside of containers

Example:

• docker run -v /mnt/data:/data my-image
• this command run a container from my-image, mounting /data in the container to /mnt/data on the host machine
• whatever the container writes to /data is written to /mnt/data on host machine
