docker-compose-standalone-nlu.yaml not working as expected

[pavelsr]

Describe the bug

Seems like docker-compose-standalone-nlu.yaml from examples/docker-compose doesn't work as expected - it doesn't use standalone NLU server that is running in a separate container botpress-nlu

⚠️ File docker-compose-standalone-nlu.yaml was last updated 3 years ago, but it's still in master brach, that's why I decided to draw attention to this problem.

To Reproduce

Steps to reproduce the behavior:

git clone https://github.com/botpress/v12.git
cd v12/examples/docker-compose
mkdir -m 777 botpress/data botpress/language
sed -i 's/GET_LATEST_FROM_DOCKERHUB/latest/' botpress/Dockerfile
docker compose -f docker-compose-standalone-nlu.yaml up -d

In the output of docker top botpress-server you will see:

$ docker top botpress-server
UID PID PPID C STIME TTY TIME CMD

999 1757585 1757205 1 04:17 ? 00:00:06 /botpress/bin/studio

In the output of docker logs botpress-server you will see something like:

Expected behavior

The output of docker top botpress-server shouldn't contain /botpress/bin/nlu

The output of docker logs botpress-server shouldn't contain url=https://lang-01.botpress.io, lang server must be http://botpress_nlu:3200
