[BUG] MONGO_HOST variable do not works

[amigthea]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I already have a production environment, with a mongo database. I need to change the database host and I need to pinpoint it to a ipv4 address, but when I try to change the docker MONGO_HOST variable value, application fails to start because it tries to reach the old value, the container hostname unifi_db, instead of the new ip address

Caused by: com.mongodb.MongoTimeoutException: Timed out while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}. Client view of cluster state is {type=UNKNOWN, servers=[{address=unifi_db:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketException: unifi_db}, caused by {java.net.UnknownHostException: unifi_db}}]

how can I fix that?

Expected Behavior

changing variable should reflect the changes in the application configuration

Steps To Reproduce

1. change docker compose MONGO_HOST variable

solved, the file system.properties in the container persistent volume was not being written, I deleted it and now the application is using the variable value
