kubernetes installed by kind can't pull container images

I've installed k8s with kind using the instructions from the course. When I started with the first lab with consul, I found that my kubelet running inside consul-control-plane container fails to pull images of the emojivoto applications:
[email protected]:~/lab3.2$ kubectl get po -n emojivoto NAME READY STATUS RESTARTS AGE emoji-65df4d68f7-9nhqf 0/1 ImagePullBackOff 0 19m vote-bot-7c59767698-dk5pc 0/1 ImagePullBackOff 0 29m voting-768f496cd8-8xlrd 0/1 ErrImagePull 0 29m web-545f869fc4-6z5g8 0/1 ImagePullBackOff 0 29m
in order to exclude any problems with name resolving I've changed nameserver in /etc/resolve.cof to google dns and I can see that name resolution works from within the consul-control-plane container.
[email protected]:~/lab3.2$ docker exec -it consul-control-plane bash [email protected]:/# cat /etc/resolv.conf nameserver 8.8.8.8 [email protected]:/# curl -v google.com * Trying 172.217.23.142:80... * TCP_NODELAY set * Connected to google.com (172.217.23.142) port 80 (#0) GET / HTTP/1.1
But at the same time in journal for kubelet that is running inside that container I still see that it fails to pull the image
[email protected]:/# journalctl -fu kubelet.service -- Logs begin at Tue 2021-01-26 20:44:41 UTC. -- Jan 26 21:24:51 consul-control-plane kubelet[4620]: E0126 21:24:51.745867 4620 pod_workers.go:191] Error syncing pod 5896010f-a7b1-41d4-92ff-4460b862a146 ("voting-768f496cd8-8xlrd_emojivoto(5896010f-a7b1-41d4-92ff-4460b862a146)"), skipping: failed to "StartContainer" for "voting-svc" with ImagePullBackOff: "Back-off pulling image \"docker.l5d.io/buoyantio/emojivoto-voting-svc:v11\"" Jan 26 21:24:53 consul-control-plane kubelet[4620]: E0126 21:24:53.745825 4620 pod_workers.go:191] Error syncing pod 40b8f63d-c56c-4916-a07a-5c6ef05f3b1c ("vote-bot-7c59767698-dk5pc_emojivoto(40b8f63d-c56c-4916-a07a-5c6ef05f3b1c)"), skipping: failed to "StartContainer" for "vote-bot" with ImagePullBackOff: "Back-off pulling image \"docker.l5d.io/buoyantio/emojivoto-web:v11\"" Jan 26 21:25:01 consul-control-plane kubelet[4620]: E0126 21:25:01.746200 4620 pod_workers.go:191] Error syncing pod 053f9fe8-ab56-4653-a23d-1584c4a1a0f0 ("web-545f869fc4-6z5g8_emojivoto(053f9fe8-ab56-4653-a23d-1584c4a1a0f0)"), skipping: failed to "StartContainer" for "web-svc" with ImagePullBackOff: "Back-off pulling image \"docker.l5d.io/buoyantio/emojivoto-web:v11\""
I tried to restart it, but it didn't help. Any ideas how I can troubleshoot this further?

One addition. When I changed registry from docker.l5d.io to just docker hub (default one) it worked:
[email protected]:~/lab3.2$ kubectl get po -n emojivoto NAME READY STATUS RESTARTS AGE emoji-5fcc588b77-m7kdd 1/1 Running 0 44s vote-bot-658cb85b6-xj4zz 1/1 Running 0 44s voting-5858f494d-cx2dp 1/1 Running 0 44s web-7ddc6b67d6-zcxps 1/1 Running 0 43s
