Kubernetes deployment with docker image

I am running Kubernetes(Minikube) on my local mac.

I am trying to setup a deployment with docker image and getting the below error. But, the hello-world deployment with the docker image "gcr.io/google-samples/node-hello:1.0" works as expected.

I am able to pull the image from a console on my local machine. Am i missing any setting here?

"Failed to pull image "docker.XYZ.com/dpace/dev/docker-service": rpc error: code = Unknown desc = Error response from daemon: Get https:/docker.XYZ.com/v2/: dial tcp: lookup docker.XYZ.com on 10.0.2.3:53: read udp 10.0.2.15:59292->10.0.2.3:53: i/o timeout"

I am able to pull the image using "docker pull docker.XYZ.com/dpace/dev/docker-service" in my local machine without any auth issue. It doesnt need auth for pulling images.

I tried loggin into minikube VM and docker images returns the following.

$ docker images REPOSITORY TAG

Though the images are there, when i try to pull the exising image, it fails with the below error.

$ docker pull gcr.io/google-samples/node-hello:1.0 Error response from daemon: Get https://gcr.io/v2/: dial tcp: lookup gcr.io on 10.0.2.3:53: read udp 10.0.2.15:44023->10.0.2.3:53: i/o timeout

When i try "docker login docker.XYZ.com", it prompts me to enter the credential. It throws the below error after entering the password. Same error while trying to pull the image also.

"Error response from daemon: Get https://docker.XYZ.com/v2/: dial tcp: lookup docker.XYZ.com on 10.0.2.3:53: read udp 10.0.2.15:41849->10.0.2.3:53: i/o timeout"

The command "curl google.com" also not working. "Could not resolve host: google.com"

Any setting to be done inside minikube vm. I use virtual box.

Does this question help? – Pace
You're likely missing the required authentication/docker login credentials to pull that image. Double check if the image you're trying use is public. Then check that the registry you're trying to hit is accessible from inside the minkube virtual machine. – ffledgling

Looks like DNS in your minikube is broken, that's why you cannot pull anything.

Here is an Issue on Github with the similar problem.

Try to update your minikube and your hypervisor (in most of cases it is Virtualbox) to the last version (check here) and recreate a cluster, it should help.
