QUESTION
I am trying to start up a couple of containers locally using k8s but container creation is stopped cause of ImagePullBackOff, ErrImagePull. The yaml is fine, tested it on another workstation. And i can pull images using regular docker. But it fails in k8s/minikube environment
Error container logs is
...ANSWER
Answered 2022-Apr-02 at 13:06It is a kind of workaround for the problem, if you can pull image using docker pull then do it on all the worker nodes and then add an
ImagePullPolicy:IfNotPresent
inside the yamls where you are mentioning image name, then k8s will first check whether it is present inside the machine and if yes then directly use it

I'm following a tutorial https://docs.openfaas.com/tutorials/first-python-function/,
currently, I have the right image
...ANSWER
Answered 2022-Mar-16 at 08:10If your image has a latest
tag, the Pod's ImagePullPolicy
will be automatically set to Always
. Each time the pod is created, Kubernetes tries to pull the newest image.
Try not tagging the image as latest
or manually setting the Pod's ImagePullPolicy
to Never
.
If you're using static manifest to create a Pod, the setting will be like the following:

trying to follow the Getting Started instructions for Deploying a Cloud Run service with Cloud Code in Intellij (deploying HelloWorld Flask app container with Cloud Run: Deploy
) but getting the following error, any idea why this might be happening
it worked initially i.e. deployed the app on Cloud Run service using the same steps, and then started throwing this error after a week or so when trying to redeploy, there was no change in project settings.
intellij and docker versions are the latest.
authenticated to google cloud project with gcloud auth login --update-adc
The local run works fine (Cloud Run: Run Locally

but running the Cloud Run: Deploy
throws this "code 89" error

You can access http://localhost:8000 with kubectl port-forward 8000:8000
. You can also expose as NodePort or LoadBalancer where port-forward will not be required.

I'm having a strange behavior, which I'm afraid is not easily reproducible. Maybe you can give me a hint..
On a Ubuntu 18.04 machine and inside a venv I'm running pytest --doctest-modules
using Python 3.8.0 on a module which uses __future__.annotations
ANSWER
Answered 2021-Aug-24 at 20:29this maybe shouldn't have been backported in cpython 3.8 -- https://github.com/python/cpython/pull/19835
the flags changed in incompatible ways between 3.8.2 and 3.8.3, meaning if you have a pyc file from a newer version it will not work properly with the older version (despite being marked as compatible for cpython 3.8)
the patch linked above adjusted the flags to avoid collisions with other compiler flags

I've got a fluentd.conf file and I'm trying to use (copy) it in my minikube cluster (works fine in a docker container). The steps are the following:
- Ill build (in my minikube docker-env) the docker image with the following commands Dockerfile:
ANSWER
Answered 2021-Jul-20 at 07:11This happens because you are mounting a volume in the same folder.
Inside your image, the config file is placed in /fluentd/etc/fluent.conf
.
In your pod, you mount the fluentd-claim0
volume into /fluentd/etc/

QUESTION
I am trying to use Ingress in minikube by minikube addons enable ingress
. However, currently Ingress cannot be used with minikube when the driver is docker
on macOS based on this issue ticket.
So I turn to use hyperkit
or virtualbox
as driver. One image that need to be pulled when enabling Ingress is k8s.gcr.io/ingress-nginx/controller:v0.44.0
. However, k8s.gcr.io is blocked in my current location.
So I try to use a VPN in global mode for my computer. However, I met this issue that hyperkit is unable to access k8s.gcr.io when the VPN is in use.
Then I found this document https://minikube.sigs.k8s.io/docs/handbook/vpn_and_proxy/
My VPN is listening at 127.0.0.1:1087, I set

Answered 2021-Jul-16 at 07:14Downloading this image using docker, exporting it to file, transfering it to minikube VM and importing it to local docker registry, like in this thread has solved the problem.

QUESTION
I have been getting more and more into k8s and I am trying some stuff on a personal VPS I have. I have created a Deployment of a POD that uses another Service internally. I would love to validate that these two services are being somewhat loadbalanced.
Here was my attempt to create this: I have a simple service which I called metric-test which only has one endpoint that counts how many times it was called, logs it and returns this information. For this I used the microframework jooby since I had familiarity with it and could get a fast start.
The code of this simple app can be found on github
Also on the repository I have added the deployment.yaml file with which I use to push it to my local version of minikube (which simulates my k8s env).
Steps taken:
- Use this cmd to compile docker image into minikube repo:
eval $(minikube docker-env)
- I now build the project's docker image with
docker build . -t metric-test1
- I then apply the deployment file with
kubectl apply -f deployment.yaml
(the file is also on the github link
This gives me a Service of type ClusterIP (which is what I want since it should not be accessible from outside) and 2 PODS containing the jooby code. Here is the deployment.yaml
file:
ANSWER
Answered 2021-Jul-02 at 19:13If I remember correctly, TCP load balancing was not working when using port forwarding. Try to run the script from a container inside k8s instead of doing port forwarding.
