First mount the volume on the server that runs docker.I tried mounting the shares read-only, but this (unsurprisingly) also failed.Īm I correct in understanding that Docker prevents any use of mount inside containers?Ĭan anyone think of another way to accomplish this without mounting a CIFS share on the host and then mounting the host folder in the Docker container?ĭo not make your containers less secure by exposing many ports just to mount a share. If I'm reading this correctly, it appears that Docker explicitly denies the ability to mount filesystems within a container. I get mount error(13): Permission denied.Ī little research online led me to this article about Docker security. So I tried to add the appropriate entries to the /etc/fstab file in the container & mounting them with mount -a. Now I'm trying to put together a production container which will be run on a different server and which doesn't rely on the CIFS share being mounted on the host. On my development machine I have the appropriate folders mounted via entries in /etc/fstab and the host mount points are mounted in the Docker container via the -volume argument. The files I'm trying to access are image files created for our clients and the web application displays them as part of the client's portfolio. This application needs to access some files on our corporate file server (Windows Server with an Active Directory domain controller). I have a web application running in a Docker container.
