Docker tmpfs mount

  • It is one of the 3 options available for user to store data. unlike volume & mountfs, the data stored under tmpfs mount is not persistent, it is stored in the host memory.
  • This is used when we don't want to write sensitive data or data that relates to non-persistent application state in the container layer or on the host FS.

  • usage:

1st Method:

docker run -itd --name temp_alpine --tmpfs /u01/temp alpine

2nd Method:

docker run -itd --name temp_alpine --mount
type=tmpfs,destination=/u01/temp alpine
