this makes the dashboard domain resolve internally to nginx
can test with `getent ahosts my.domain.com` inside the container.
Currently, we allocate 50% as RAM and 50% as swap. The manifest is
usually quite conservative on memory values. This means that we set
up a system where the app is applying memory pressure almost immediately.
This then swaps things randomly and increases cpu usage (kswapd shows
up in the profile).
To rethink the whole situation: we should not cap apps with a swap limit at all.
The memory hard limit is what is important. By redefining memoryLimit , we are
doubling every container's memory and it's good that we over allocate this.
docker is using a extra udp port for every container. when there is
a lot of containers, a lot of random udp ports get used up. this causes
problems when installing apps that require contiguous port ranges
we used:
psql -Uroot --dbname=postgres --command="ALTER SYSTEM SET shared_preload_libraries = 'vectors.so'"
the above wrote to the auto config file and required a reboot. this resulted in

ADVICE: If you encounter this error for your first use of pgvecto.rs, please read `https://docs.pgvecto.rs/getting-started/installation.html`. You should edit `shared_preload_libraries` in `postgresql.conf` to include `vectors.so`, or simply run the command `psql -U postgres -c 'ALTER SYSTEM SET shared_preload_libraries = "vectors.so"'`.
