Expected script sucessfully executed, since it is provided and expected to be tested.

Hi @mou , I would suspect you have setup a specific volume for the cache or similar but I can confirm to you 1.344.3 work well on all our dedicated EE instances which are all on kubernetes using our official helm charts

Thank you, @rubenf for quick reply. Most likely. I just followed helm chart setup. Should I add an emptyDir volume for cache and mount it in expected location?

rubenf•5mo ago

If you used the stock helm chart without modification, then it must be your kube flavor which doesn't grant write permission by default or similar you can try with minikube for instance, it will work fine we are ourselves on EKS

Indeed. Looks like container is intended to be run as root. But i found my values has a non-root security context DId not know why i set up it this way or from where i copy pasted this security context @rubenf removing securityContext solved my issue. Sorry for bothering.
