Hi all,

Since few days, I try to install a K8s cluster with kubadm but when I run the command kubeadmin init I’m experiencing image pull issues…

sudo kubeadm init --pod-network-cidr=172.16.0.0/16

[ERROR ImagePull]: failed to pull image k8s.gcr.io/kube-apiserver:v1.15.1: output: Error response from daemon: Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)**
…
…

I tried to manually download the image with noluck

docker pull k8s.gcr.io/kube-apiserver:v1.15.1

Error response from daemon: Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)**

Last week, the same command worked like a charm … I don’t have any proxy or firewall rules configured in my network.

Any ideas?

Thanks

Hi all,

Just to add some news to this thread. In fact, my home internet connection seems to have issues when downloading K8s images. I tried this morning from my customer’s connection and it worked like a charm.

I will investigate what’s wrong with home network.
