[calibre-web] Pod does does terminate with [s6-finish] sending all processes the TERM signal. about charts

[somerandow]

Could you provide your values.yaml?
My thought here is that the pod may be taking to long to bring up the webui.
I say this as there are other steps that should run after 30-config.

Typically I have seen this run slow on certain types of persistent volumes. (Namely NFS)
As a quick test, have you tried increasing initialDelaySeconds for both the readiness and liveness probes?
Also, I would try disabling persistence and seeing if the pod initializes properly.

I use kadalu as storage backend

No, but I can try

I've doubled the thresholds of the liveness-probe but the result is still the same

[somerandow]

Thanks for the info!

I used to use kadalu, can't remember if I had issues of this sort with it.

Can you try disabling persistence for the config pvc? Wondering if that narrows things down.

[papanito]

Good hint, now it looks like this

[cont-init.d] 10-adduser: exited 0.
[cont-init.d] 30-config: executing... 
cp: cannot stat '/app/calibre-web/gdrive.db': No such file or directory

Awesome! So I'm a bit fuzzy on gluster and its configuration options, but here's my 2 cents.
Even testing this just now on NFS, which I would expect to perform worse, I am able to get the pod to initialize in <5 sec.

I would chalk this up to a storage related issue unfortunately. Are you seeing this issue with other pods/charts?
Unfortunately, I don't see many configuration options documented by Kadalu either.

[papanito]

No I have not seen such issues yet. I've updated kadalu anyway maybe this helps. I will further look into it

[papanito]

Mhh I will check with the kadalu guys, maybe they have a clue...

[papanito]

@WojoInc thanks for your help.

Talked to the kadalu folks and the referred me to issue kadalu/kadalu#295. I've updated my kadalu csi to the latest version and it seed that already helped. At least pods are running. I will close this issue for now.
