limit redis to 1gb

[davidbeig]

Following the documentation of the deploy configuration in docker-compose, we can limit resources to a specific container.

In this case we are limiting the redis database to only 1Gb of memory.

https://docs.docker.com/reference/compose-file/deploy/#resources

To test if you can do:

docker compose up redis -d
docker stats # to see that the memory has been limited to 1Gb
```

Also check for redis maxmemory and maxmemory-policy

```bash
redis-cli CONFIG get maxmemory
redis-cli CONFIG get maxmemory-policy
```
