I Declare Defeat - Mount NFS in Docker

Today I've tried to mount a NFS into a docker volume via the following means:

1. Mount the NFS on the host and create a docker volume using the absolute path
2. Create a docker volume via NFS

Both variants have failed miserably, in hte sense that I could get the docker container to "see" it, but read-only.

I've used the following sources:

• Ansible docker module
• Samba in docker
• bind propagation
• Making an NFS mount on the host visible and read-write inside Docker container
• Docker the ansible way
• Docker NFS volume using Ansible
• Docker sdk for python
• Mapping UID and GID of local user to the mounted NFS share
• How to properly set permissions for NFS folder? Permission denied on mounting end.
• Ansible mount module

For the time being, I'll fall back to a different strategy:

1. Mount the NFS share
2. Create a local folder
3. Unpack an archive form the NFS share to the local folder
4. Create a docker volume pointing to the local folder
5. Start the docker module
6. Create a job to archive the content of the local folder into a tarball and copy it to the NFS share

This way, I'll have a backup on the NAS, in case I need to redeploy the docker image somewhere else.

HTH,
