I'm trying to use Kubernetes with Docker. My image runs with Docker. I have one master-node and two worker-nodes. I also created a local registry like this $ docker run -d -p 5000:5000 --restart=always --name registry registry:2 and pushed my image into it. Everything worked fine so far.

I added { "insecure-registries":["xxx.xxx.xxx.xxx:5000"] } to the daemon.json file at /etc/docker. And I also changed the content of the docker-file at /etc/default/to DOCKER_OPTS="--config-file=/etc/docker/daemon.json". I made the changes on all nodes and I restarted the docker daemon afterwards.

I am able to pull my image from every node with the following command:

sudo docker pull xxx.xxx.xxx.xxx:5000/helloworldimage

I try to create my container from the master node with the command bellow:

sudo kubectl run test --image xxx.xxx.xxx.xxx:5000/helloworldimage

Than I get the following error:
