[wildfly-dev] How to use environment variables with WildFly and OpenShift

Hi Experts, I had a couple of tries with OpenShift and WildFly to spin up a simple application (the EAP quickstart `cmt`). I installed `crc` [1] to run OpenShift locally and `oc` [2] to control it. What I tried so far: * Employ wildfly-centos7 [3] directly and then spin up a new-app with the command `oc new-app https://github.com/wildfly/quickstart.git --context-dir=cmt --image=quay.io/wildfly/wildfly-centos7 --env SERVER_CONFIGURATION=standalone-full.xml` * Build the WFLY image from "scratch" and then spin up a new-app with the env variable `--env SERVER_CONFIGURATION=standalone-full.xml`...more or less what it is suggested in [4] but adding the env variable, i.e. `oc new-app wildfly-quickstart/cmt -e SERVER_CONFIGURATION=standalone-full.xml` (where wildfly-quickstart is the OpenShift project I am using) In both cases, I get very close to success but what does not work is `--env SERVER_CONFIGURATION=standalone-full.xml`. My WildFly server gets set up with standalone.xml, which is not enough for my quickstart. As a side note, I can see `SERVER_CONFIGURATION=standalone-full.xml` among the environment variables of the WFLY pod. I also ran a couple of experiments playing with JAVA_OPTS_APPEND (e.g. `JAVA_OPTS_APPEND=-Djboss.server.default.config=standalone-full.xml`) but it did not help. So my questions would be: * Is there a different way to pass env variables when applications are created? If that is the case, would it be worth mentioning it here [5]? * Have I missed something else?
