Web pod crashes on startup — session_cookie_key error with default chart config

[VPLEV23]

Problem

The web pod crashes immediately on every fresh deployment:

Error while loading /home/netdisco/perl5/bin/netdisco-web-fg: The setting session_cookie_key must be defined at /home/netdisco/perl5/lib/perl5/Dancer/Session/Cookie.pm line
38.
Compilation failed in require at /home/netdisco/perl5/bin/netdisco-web-fg line 59.
BEGIN failed--compilation aborted at /home/netdisco/perl5/bin/netdisco-web-fg line 59.

Root cause

After some debugging I found the chart never sets DANCER_APPDIR or DANCER_ENVIRONMENT — confirmed with grep -r "DANCER" charts/netdisco/ which returns zero results.

Without these, the web process cannot find session_cookie_key from the mounted ConfigMap and crashes before starting.

Same problem over here too.
I've been trying to deploy in our PRE environment considering the great experience we've had with the docker images and sadly I've encountered this.

hey @VPLEV23 @Andalu30 sorry for the delay, I missed that.

I think the real cause is almost certainly the web pod starting before db-init seeds the dancer_session_cookie_key row in the database. The pre/post hooks were messed in the previous versions. It should be fixed in 0.5.3.

in case you using ArgoCD you should override the h with an annotation:

dbInit:
  annotations:
    argocd.argoproj.io/hook: PostSync

can you try again and give me a update? again sorry for the delay

No worries! Our cluster still needed some love so the team has been happily working with the docker deployment.

I'll try to get it running if I have time and report back.
Thanks for the help!
