Docker Swarm data not persisting in Local

Users

Hi Team,

I am posting here as a last resort after I was unable to figure out, how to persist whatever data I put into Dgraph.

For the last 3 days, I have been re-inserting data into the Dgraph after reinitializing the Docker Swarm cluster.

I have tried searching, but always end up with results like Gluster, Ceph, MinIO.

What am I doing wrong?

P.S. I use a slightly modified Docker Compose file from Dgraph GitHub repo.

Hi @abhijit-kar Can you show us your modified docker-compose file.

docker-compose.yaml (780 Bytes)

I just removed high availability constraints from it!

Referenced it from: dgraph/contrib/config/docker/docker-compose-ha.yml at master Ā· dgraph-io/dgraph Ā· GitHub

Hi @abhijit-kar

You need to put a volume mount at the /dgraph location within the docker container. Add a volume for alpha and a separate volume for zero, and mount them both at /dgraph in the respective container.

I see a /honeycomb, but Iā€™m not sure what that is used for. If this is the data directory, you have to ensure that you pass options to dgraph to start with that data directory.

I was learning Docker Swarm, and just assumed I could change volume mount to any name.

In this case, from /dgraph to /honeycomb.

Thank you for clearing that up.
