Hi @markdrew I just noticed your comment. I don’t know if you figured it out, but the env var LUCEE_EXTENSIONS is not what Lucee proper looks for. I believe that name is specifically something looked for in the official lucee image that gets passed through to an env var or JVM prop of the name Lucee is actually looking for which is either lucee-extensions (deprecated) or lucee.extensions
The CommandBox image doesn’t provide a passthrough env var called LUCEE_EXTENSIONS. We could, but I’m not sure what the point would be since it’s almost exactly named as the built in env var, just non-standard. With the CommandBox image, just provide the environment variable in the format Lucee itself is looking for and everything should work.
Also, FWIW, since these links are so hard to find, I’ll leave them here as well. Here’s the docs for that env var (which seriously needs some love since it doesn’t even cover specific versions!):
http://docs.lucee.org/guides/running-lucee/configuring-lucee/system-properties.html
And here is the “living” Google Doc that lists all possible env vars and system props. The one in question is on line 5.
