Solved Greenlight - A simple front-end interface for your BigBlueButton server
I've given the app package a spin and it generally looks good. At least seems to work well with the default demo BBB backend instance!
One thing I noticed is, that there is a
/app/data/being created. Is that required? Note that
/tmpwould be purged of old data on a schedule, while
/runis not, but both are useful for temporary files depending on use-case. Not sure what
/app/data/tmpis for in that picture.
Still have to see how I can test this with some non demo BBB instance.
I will fork your package project into the cloudron namespace on gitlab and add you as a contributor there if that is ok?
Then we can finish up the rest (tests, metadata, ...) if even required
@nebulon I will look into
/app/data/tmpagain. There was a reason why I did that instead of using the normal
Also yes I will maintain this app as the contributor.
Still have to see how I can test this with some non demo BBB instance.
Using the file manager you need to set
BIGBLUEBUTTON_SECRETand restart the app. But I think your intention was more like "I don't want to setup a BBB instance to test it" or "I need a BBB instance to test it."
We just had a call using the default demo BBB server and it was good enough. So I think we can release this frontend app in the next days. Maybe you can try to figure the
/tmpfolder issue or at least that we know why it is as you have packaged it and I will do the meta info and then publish it.
The required env variables to be set are already well documented by you
This happens if I do not symlink

With a symlink to
/app/data/tmp/seems to be no Problem.
Tests running clean.
@BrutalBirdie maybe symlink it to /tmp/bbb/tmp instead? Anything under /app/data will be backed up.
@girish already changed it to
/tmp/only and it's working fine.
Would you recommend an extra folder in
Would you recommend an extra folder in /tmp/?
Just a convention we follow since it helps in chow'ing more easily. For example, we could create
/tmp/greenlight/cacheetc. To keep all the tmp stuff of an app "isolated". Then, we can do "chown -R xx /tmp/greenlight" somwhere in the script and not chown the whole tmp. Also, helps when we have multiple processes running with different permissions etc. But really, just a convention across packages.
BTW, one more thing is that files under
/tmpare cleaned up automatically by Cloudron periodically. Things under
/runaren't. Some apps don't work properly if files go missing randomly under them. Just a heads up in case we get reports like "greenlight suddenly stopped working after 3 weeks". The fix for those is to use something like
Will close this here and create a new section in the forum, because I've just pushed out the app package as unstable! Thanks a lot @BrutalBirdie for all the work
