[keycloak-user] Adding alwaysHttps to Hostname SPI in Docker

I'm trying to figure out how to add the "alwaysHttps=true" to the Hostname Provider in Keycloak running under Docker. I've tried the following: 1) Modifying the standalone.xml and adding with sed: name=properties.alwaysHttps,value="true" 2) Adding a CLI to the startup-scripts directory, but this fails since the server isn't running and the connect doesn't happen. 3) Modifying the tools/cli/hostname.cli file and adding: /subsystem=keycloak-server/spi=hostname/provider=fixed:write-attribute(name=properties.alwaysHttps,value="true") What is the correct approach to adding the alwaysHttps when overriding the default Dockerfile ?
