Kubernetes executor on Gitlab ERROR: Job failed: image pull failed - docker

I tried to setup Kubernetes executor on Gitlab, but I have this error:
ERROR: Job failed: image pull failed: image pull failed for
someprivateimage:latest,
this may be because there are no credentials on this request. details:
(Error response from daemon: {"message":"Get
https://someprivateimage/latest: denied: access forbidden"})
Anyone have idea why?

You need to either:
Have the docker daemon on your node login to the docker registry. Have a look at the docker login docs
Have the pod definition pull from a private registry. Take a look at these kubernetes docs
If you're going to be doing this often, I recommend the first one.

Unable to pull image from JFrog docker registery

I'm using JFrog repository as my private jfog repo. And I have specified the secret in order to authenticate it. The pod fails with an ImagePullBackOff error, when I describe the pod I see
Failed to pull image "private_registry/image_name": rpc error: code =
Unknown desc = failed to pull and unpack image
"private_registry/image_name": failed to do request: Head
https://xx.xx.xx.xx:port-number/v2/<docker-registryname>/<application-name>/manifests/<tag>:
http: server gave HTTP response to HTTPS client Warning Failed
23m (x4 over 24m) kubelet, worker01 Error: ErrImagePull
when I pull the same image using docker pull , the image get pulled successfully
While having the HTTP server communicating with the HTTPS server (probably due to the usage of a self-signed certificate) being the private registry, registering the concerned registry as an insecure registry with the docker client could resolve the docker error.
{ "insecure-registries":["IP:PORT"] }
An entry similar to the above need to be included in the /etc/docker/daemon.json file and considering the environment to be in K8s, it needs to be configured on all the nodes.

Unable to pull image from the Gitlab container registry

I have created some images in the Gitlab Container Registry. I am unable to pull them using docker on my local system. The login command succeeds but when I type the following command:
docker pull reg-gitlab-project.company.com/services/palimited/integrationservices/springbootproject/springbootproject:latest
I am getting the following error
Error response from daemon: Head "https://reg-gitlab-project.company.com/v2/services/palimited/integrationservices/springbootproject/springbootproject/manifests/latest": denied: access forbidden
I am unable to figure out why this error is occuring? Can anyone guide me.
You need to authenticate with the container registry at reg-gitlab-project.company.com before issuing a docker pull command.
See, GitLab Docs: Authenticate with the Container Registry.

Error while deploying local python-based docker image on minikube kubernetes cluster

I am trying to deploy a Python flask based application container on minikube locally in an attempt to learn kubernetes. But when I try the below command:
minikube kubectl -- create deployment hello-1 --image=mini-images
I get following error:
Failed to pull image "mini-images": rpc error: code = Unknown desc = Error
response from daemon: pull access denied for mini-images, repository does not
exist or may require 'docker login': denied: requested access to the resource
is denied
I also tried to build the docker image directly following instructions for this page, but the results are same.
What am I doing wrong?
Please consider using the flag "--image-pull-policy" set to "never" when trying to use locally imported images:
minikube kubectl -- create deployment hello-1 --image=mini-images --image-pull-policy='never'

Fixing Docker "build from" failure on repo (insufficient_scope: authorization failed) where "docker pull" (of JBPM) succeeds

Trying my first-ever "docker build" I am seeing:
failed to solve with frontend dockerfile.v0: failed to create LLB definition: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed
I can get the image with docker pull:

I am logged in to Docker Hub so how do I correct this - the only non-commented out line in my - Dockerfile - from failing (and why)?

K8S on Docker Desktop cannot pull private repo - pull access denied

I have logged in to the Docker hub using the CLI command: docker login. Entered username and password and I can pull and push images to Docker hub.
However, my K8S can't. I am trying to apply a deployment that should pull those images into its pods but I got the following error when running kubectl describe pod POD_NAME:
Warning Failed 9s kubelet Failed to pull image "myprivate/repo:tag": rpc error: code = Unknown desc = Error response from daemon: pull access denied for myprivate/repo, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
How to make the docker run in the pods to also be logged to the docker hub as well as doing it from my terminal?
Create "image pull secret" and define on your deployment. Here is how you can do https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
