I am currently reading https://docs.docker.com/storage/volumes/ which talks about docker volume.
And my situation is: I have a rasa_nlu container which has a /app directory inside, and my host has an empty directory called
My goal is to map/bind/connect
/root/rasa_nlu in my host machine to
/app in my rasa NLU container.
So I first run
docker volume create rasa_nlu_vol
And I run
docker run -d -p 5001:5000 --mount type=volume,source=rasa_nlu_vol,target=/app --name rasa_nlu_test rasa/rasa_nlu:latest
While I can successfully run the container, the data in container is now in
/var/lib/docker/volumes/rasa_nlu_vol/_data, which I don’t want to.
Yes I know I can simply use
ln -s to solve this problem, but I want a much clever solution, which is to specific both the source and target absolute path directory.
Can it be done?
By the way, below are my suggestion:
I don’t know why I need to run
docker volume create <some_name> before running
docker run, can it be simplified by automatically create a volume for us when we use
--mount type=volume,name=my_fancy_name_about_my_vol,src=/another_fancy/my_source,target=/final_fancy/my_dst? It is much simpler!
