It is this daemon we talk to when we want to upload images. This is done by marking the registry endpoint in /etc/docker/daemon.json: Restart the Docker daemon on the host to load the new configuration: …should succeed in uploading the image to the registry. Note that this is an insecure registry and you may need to take extra steps to limit access to it. MicroK8s contains a reference to this registry called 'local.insecure-registry.io'. Instead of diving into the specifics of each setup we provide here two pointers on how you can approach the integration with Kubernetes. 18.2.5.3. We recently released MicroK8s and noticed that some of our users were not comfortable with configuring containerd with image registries. As a result the first thing we need to do is to tag the image we are building on the host with the right registry endpoint: If we immediately try to push the mynginx image we will fail because the local Docker does not trust the in-VM registry. As described here, users should be aware of the secure registry and the credentials needed to access it. You can install the registry with: microk8s enable registry To achieve this, imagePullSecrets is used as part of the container spec. There are a lot of ways to setup a private secure registry that may slightly change the way you interact with it. Working with an insecure registry Without additional configuration, the registry started in the step above is insecure. The container images are found either locally, or fetched from a remote registry. Kubernetes manages containerised applications. Enable local registry for microk2s: microk8s.enable registry Checking: watch microk8s.kubectl get all --all-namespaces container-registry pod/registry-577986746b-v8xqc 1/1 Running 0 36m. The Docker daemon sees (on /etc/docker/daemon.json) that it trusts the registry and proceeds with uploading the image. "io.containerd.grpc.v1.cri".registry] -> [plugins. The docker daemon used by microk8s is configured to trust this insecure registry. Add the registry endpoint in Note: these instructions can easily be adapted to expose a docker private registry container running on any kubernetes cluster – not just microk8s. This will start a registry on port 32000 that can be accessed by other nodes in the cluster via 10.0.0.1:32000. The full story with the registry. host: myapp.192-168-0-1.nip.io, where 192.168.0.1 is the ip address of your microk8s node. container-registry pod/registry-577986746b-v8xqc 1/1 Run Working with MicroK8s’ built-in registry. MicroK8s contains a reference to this registry called ' local.insecure-registry.io '. This post takes you through the steps involved in getting MicroK8s up and running on an Ubuntu … Let’s assume the private insecure registry is at 10.141.241.175 on port 32000. Tool for setting microk8s on Ubuntu VPS over SSH. It is an insecure registry because, let’s be honest, who cares about security when doing local development :) .
