vod2pod cannot connect to redis on podman

issue description:

The vod2pod cannot connect to the Redis server started using the same docker compose script. The only thing I changed in the docker-compose.yml is the host port to 9001.

I use podman-compose up to start the containers.

Log:

The problem seems to be that podman does not populate the internal dns with "redis", did you change the name of the redis container inside the compose?

[madiele]

You could also play around with the hostname field to see if it helps

[madiele]

Based on this stackoverflow answers you might also be missing the dns plugin for podman

https://stackoverflow.com/questions/66895304/unable-to-resolve-hostname-with-docker-compose-and-podman

Give it a check

Thanks a lot for coming back to this issue. I will take a look later today to see if the missing plug-in is the problem.

The compose config is not changed from the one provided in the repo.

I checked my setup, indeed the dnsname plugin was missing for cni. I would also need to enable the plugin for the existing network configs.

However, it was suggested to move to netavark for future podman networking, so I will try that instead (plus the aardvark-dns plugin)

Ok feel free to close the issue when you tested that it works ✌️
