Nextcloud setup with env-file not working

[kitkittia]

I have this env file:

MYSQL_ROOT_PASSWORD=mysql_root_password
MYSQL_DATABASE=nextcloud
MYSQL_USER=nc_admin
MYSQL_PASSWORD=mysql_nc_password
MYSQL_ALLOW_EMPTY_PASSWORD=no
#MYSQL_HOST=127.0.0.1
NEXTCLOUD_ADMIN_USER=nc_admin
NEXTCLOUD_ADMIN_PASSWORD=nc_password

If I omit MYSQL_HOST nextcloud appears to ignore all the other MYSQL_* environment variables and assumes I chose a sqlite database. If I however enable M̀YSQL_HOST, nextcloud registers that I want a mysql database.

Comment #1201 (comment) mentions this explicitly.

Is this a bug, or is the documentation lacking?

This behavior is expected:

docker/docker-entrypoint.sh

Line 137 in d7ea12f

elif [ -n "${MYSQL_DATABASE+x}" ] && [ -n "${MYSQL_USER+x}" ] && [ -n "${MYSQL_PASSWORD+x}" ] && [ -n "${MYSQL_HOST+x}" ]; then

Then this must be fixed in the README

Fixed in #1361
