'Kubernetes pull from insecure docker registry
I have stacked in this phase:
- Have local docker insecure registry and some images in it, e.g. 192.168.1.161:5000/kafka:latest
- Have kubernetes cloud cluster, for which I can access only via ~/.kube/config file, e,g. token.
Need to deploy below deployment, but kubernetes cannot pull images, error message:
Failed to pull image "192.168.1.161:5000/kafka:latest": rpc error: code = Unknown desc = Error response from daemon: Get https://192.168.1.161:5000/v2/: http: server gave HTTP response to HTTPS client

ON Kubernetes cluster I have created secret file "regsec" with this command:
kubectl create secret docker-registry regsec --docker-server=192.168.1.161 --docker-username=<name from config file> --docker-password=<token value from config file>
cat ~/.docker/config.json
{
"auths": {},
"HttpHeaders": {
"User-Agent": "Docker-Client/18.06.0-ce (linux)"
}
cat /etc/docker/daemon.json
{
"insecure-registries":["192.168.1.161:5000"]
}

You need to go to each of your nodes, edit the file /etc/default/docker.json
and add the following in it:
{
"insecure-registries": ["192.168.1.161:5000"]
}

I used minikube
for my Kubernetes cluster.
When I tried to apply
a Pod with an image from my private docker registry (that is local, without authentication), the Pod didn't run and describe
had a message indicating the repository wasn't reached (paraphrasing).
To fix this, I had to configure insecure-registry
for the Docker daemon. According to the Docker docs, this can be done in two ways: as a flag passed to the dockerd
command, or by modifying /etc/docker/daemon.json
(on Linux).
However, as I used minikube
to create and configure the cluster and daemon, I instead followed the minikube
docs to set the flag --insecure-registry
. The complete command is:
minikube start --insecure-registry "DOMAIN_DOCKER_REGISTRY:PORT_DOCKER_REGISTRY"
