Image not updated after pushed to Docker Hub

[bensch98]

I'm running a Kubernetes Cluster (version: 1.19.12) locally on my PC and installed keel via helm (version 3.5) with following steps:

helm repo add keel https://charts.keel.sh
helm repo update
helm install keel keel/keel --set helmProvider.version="v3"

The keel pod is now running along with an nginx example deployment.

NAME                    READY   STATUS    RESTARTS   AGE
keel-855d5498f8-cp9fd   1/1     Running   0          47m
nginx-97c944f68-z6fft   1/1     Running   0          54m

My Deployment looks like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: default
  labels:
    app: nginx
  annotations:
    keel.sh/policy: all
    #keel.sh/trigger: poll
    #keel.sh/pollSchedule: "@every 30s"
spec:
  selector:
    matchLabels:
      run: nginx
  replicas: 1
  template:
    metadata:
      labels:
        run: nginx
    spec: 
      hostNetwork: true
      containers:
      - name: nginx
        image: bensch98/nginx-test:latest
        imagePullPolicy: Always

If I uncomment and apply this:

#keel.sh/trigger: poll
#keel.sh/pollSchedule: "@every 30s"

the pod crashes can not restart. But even when the pod is running and I push a new image to my repo with tag :latest (or any other tag) the pod is not being restarted. What am I missing, or does keel not support helm v3? Issue #567 seems to describe the same or a similar bug. Is there a solution to this?

The keel-pod logs look like this:
kubectl logs keel-855d5498f8-cp9fd

I have a similar issue, but at least you need "latest" keel and debug to see more:

helm install keel keel/keel --set helmProvider.version="v3" --set image.tag=latest --set debug=true

@derjohn sorry for my late response. Didn't manage to get it to work .. Ended up writing a Python script on my own, that I'm running as a CronJob in K8s. It checks every specified amount of time if there is a new image available and updates it if necessary.

@bensch98 , me too. I used "imago" to keep track on the sha of "latest" images. https://github.com/philpep/imago
