have an application running inside docker container. the application writes log messages into local log files. how can i make the log file persistent in case the docker container stops or crashes?
Since the container are run time entity ,when i stop the image my logs/data is gone.
Thanks, Sohan
You can do this using docker volumes:
https://docs.docker.com/userguide/dockervolumes/
For example:
docker run -v /var/log/docker:/var/log your-image
will mount the log directory on your local file system. You can also get much fancier, creating containers just for data. It's all explained in the above link.
