Ah. I see. We’re running [discourse\_docker](https://github.com/discourse/discourse_docker/) with [linked web and data containers](https://meta.discourse.org/t/linking-containers-for-a-multiple-container-setup/20867), so Redis is running within our data container.

Within our data container:

```plaintext
# redis-server --version
Redis server v=5.0.5

```

So, that explains it. It looks like we need to upgrade our data container as well. That makes me more nervous. When was that requirement added? Maybe I could revert to a previous version of the web container until my reinforcements (in Australia) are awake & available. 😉
