Can't use environment variable settings

[jagauthier]

When starting a confluence docker, there is a stack dump when setting ATL_JDBC_URL:

docker run --network net --name jira -e ATL_JDBC_USER=confluence -e ATL_JDBC_PASSWORD=password -e ATL_DB_DRIVER=org.postgresql.Driver -e ATL_JDBC_URL=jdbc:postgresql://postgres:5432/confluence -p 8090:8090 -p 8091:8091 -i -t --rm docker.io/atlassian/confluence-server:7.8.1-jdk11

Not sure what is happening here. This is my first introduction to confluence.

Finally, got this. ATL_DB_TYPE needs to be set.
