ntopng pod crashes after login screen #1

Closed gdha closed 1 year ago

gdha commented 1 year ago

The docker image works fine (no crash), but when we try the same after the kubernetes helm did run successfully we get a nice admin login screen, but the log from the pod shows that it got killed immediately as seen from below output:

/tmp/run.sh: line 3:    17 Killed                  ntopng "$@"

The container image showed netstat executable not found and why was the ntopng process killed (perhaps lack of resources?)

gdha commented 1 year ago 
$ apt-file search /usr/bin/netstat
netstat-nat: /usr/bin/netstat-nat
gdha commented 1 year ago

We did rebuild the container (version v1.5) including netstat-nat (1.4.10-3build1). After commenting out the resources in the values.yaml file the pod does not crash anymore.
