I'm using helm chart of falco and here are the commands
helm repo add falcosecurity https://falcosecurity.github.io/charts
helm repo update
helm install falco falcosecurity/falco
Here's the output
NAME READY STATUS RESTARTS AGE
falco-6hlvx 0/1 Init:ImagePullBackOff 0 4m19
Once I type describe pod to know the reason behind this status, I find these events

Whenever this happens, try to pull the image directly using minikube ssh docker pull to obtain a better error message. Be aware that Docker Hub applies a download rate limit and you might have just hit it.

I'm new to Kubernetes and learning it these days. I'm trying to create a deployment with the help of kubectl and every time I create a deployment, the container is not running and I get ErrImagePull or ImagePullBackOff.
I have tried on two machines, both have the same problem.
kubectl create deployment nginx-depl --image=nginx
Following is the description of one of the deployments I was creating

Looks like you dont have internet connectivity from the cluster nodes. kubelet on the node is trying to pull the docker image from https://registry-1.docker.io/v2/ but connectivity is not established and was timed out. hence you are getting ImagePullBackOff Error

The above error is what I am seeing, when trying to install Jenkins on a minikube cluster. I am using this link and following along: https://www.jenkins.io/doc/book/installing/kubernetes/
appreciate any ideas.
I tried with minikube with virtualbox and that worked out of the box.
But, wanted to get docker working, which I wasn't able to.
Finally, I deleted everything (even reinstalled ubuntu) and re-setup k8s cluster with latest k8s version (before i tried with --version=1.19.0 of k8s)
I used: minikube start --driver=docker. and then followed the official jenkins install with helm3, that too latest, lts –
Trying to run container in microk8s.
According to https://docs.docker.com/get-started/part3/ , after deploy the service.
microk8s.kubectl get services shows:
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
bb-entrypoint NodePort 10.152.183.182 <none> 8080:30001/TCP 5m51s

microbot-service NodePort 10.152.183.80 <none> 80:31223/TCP 19
But, I can't access the bb-entrypoint service via any of following address:
localhost:30001
10.152.183.182:8080
The os is mint mate based on (ubuntu), and I have disabled ufw.
Any idea?
You have to ensure whether endpoints are created for this service or not by running kubectl get ep
In this case i'm seeing endpoints are not created because the pod was having issues in pulling the image from docker and so it i not in ready status
[root#master tmp]# kubectl get ep

bb-entrypoint 9m24s
[root#master tmp]# kubectl get po

Please help!!
The nginx plus dockerfile you referenced cannot be used for the nginx ingress controller.
You should use the nginx plus ingress controller docker image instead.
