I have an issue to create a service with image that internally mounts cifs share. This is how I map the cifs share inside the container: COPY nas-credentials /path/credentials RUN mkdir /Data RUN echo “//nas-ip/share /Data cifs credentials=/path/credentials,dir_mode=0777,file_mode=0777,nounix,se…

What’s wrong with using named volumes backed by cifs (apart from that they don’t accept a credentials file)? No one with long term docker experiences mounts networks shares inside a container, instead they use nfsv4 backed named volumes.

Thank you Meyay, I have tried with a volume created on the swarm leader, but it looks like the volume was not populated across the workers . In this case , when I create the service, the container that is starting on one of the workers is not mapping the already created one. In addition this share…

Did you declare your volumes like shown in this post: Store Volumes on a CIFS NAS - #6 by meyay ? Furthermore, volumes are locally managed, and immutable by design. If the volume declaration in a compose file is changed, the change will not be propagated to the volume configuration on the node. It …

Thank you Meyay, I have red the thread that you shared and I took care of your advice to try to switch to NFS. Unfortunately I am getting again an issue with mapping the volume. Here is the docker-compose.yml: version: '3.7' services: app: image: image volumes: - nfs-volume:/Data…

I apologize for the inconvenience. I edited the previous post.

Thank you for reformatting your post. It makes it way easier to read and to see if indentation is applied correctly. I never saw nfs mounts with credentials. Did you enable kerberos? I can see three things that could prevent the volume to be used: nfs-utils is not installed on the nodes the nfs …

Thank you for the reply. I have removed the authentication for the NFS folder and I the result is the same. When I try to mount the the NFS directly on the host with the following command , it is working: mount -t nfs -o mountvers=4 nasIP:/volume1/folder /local-folder I have the feeling that the …

It worked!!! Thank you very much for the support! I have rebooted all the nodes from the swarm cluster and now mapping and container is powering on. Thank you again!
