node-problem-detector-operator's Issues

image pull error when installed from operator hub

I just installed this operator from operato hub and I'm getting this error:

Failed to pull image "openshift/ose-node-problem-detector:v4.0": rpc error: code = Unknown desc = Error reading manifest v4.0 in docker.io/openshift/ose-node-problem-detector: errors: denied: requested access to the resource is denied unauthorized: authentication required

on the daemon set image.

image not pullable

latest version of operator uses an invalid image:

Back-off pulling image "registry.svc.ci.openshift.org/openshift/origin-v4.0:node-problem-detector-operator"

docker pull registry.svc.ci.openshift.org/openshift/origin-v4.0:node-problem-detector-operator
Error response from daemon: received unexpected HTTP status: 503 Service Unavailable

missing rbac

After installing operator 0.0.1 it logs:

node-problem-detector-2200398493\" is forbidden: user \"system:serviceaccount:openshift-node-problem-detector:node-problem-detector-operator\" (groups=[\"system:serviceaccounts\" \"system:serviceaccounts:openshift-node-problem-detector\" \"system:authenticated\"]) is attempting to grant RBAC permissions not currently held:\n{APIGroups:[\"events.k8s.io\"], Resources:[\"events\"], Verbs:[\"create\" \"patch\" \"update\"]}"

and it is not able to create a ds for the actual NPDs

kubelet-health.sh is not working inside the container

I am unable to get KubeletProblem status in API server, the status is always showing Unknown.
I tried to run the script manually on host and it is working fine.

#!/usr/bin/env bash

set -eou pipefail

data=$(curl \
  -s \
  http://127.0.0.1:10250/healthz
)

if [[ "$data" != "ok" ]]; then
  exit 20
fi

exit 0

origin@master1:/home/origin>./kubelet-health.sh
origin@master1:/home/origin>echo $?
20
origin@master1:/home/origin>v

But it is not working inside the container
