Docker mounts and empty volume

Question

I am running docker on ubuntu server 16.04 and I am running a container trying to mount a volume with my let's encrypt certificates..

I am doing:

docker run  ....  -v /etc/letsencrypt/live/mysite:/certs ....  

on mysite folder I have my .pem files, but inside my container i find the folder certs created but it is empty!! I don't know why it is not mounting the files that are inside mysite folder...

Initially mysite folder had belongs to root but I change ownership to the current user with 'chown'.. I am also running docker run with 'sudo' but it is still not coping my folder.

I have no idea what to do :(

Answer 1

Try the mount flag.

docker run -it \
--mount src=/etc/letsencrypt/live/mysite,target=/certs,type=bind ubuntu

Or move your certs to a named volume.

You'll have to move your certs into that directory given under "Mountpoint"
