The lifecycle service then starts pulling all the images of the Kubernetes internal components from Docker Hub. The request contains the required certificates (Kubernetes PKI) for the setup.

Once the Kubernetes certificates and configuration have been generated, a request is made to the Lifecycle service to install and start Kubernetes. Inside the Docker Desktop VM, a management process named Lifecycle service takes care of deploying and starting services such as Docker daemon and notifying their state change.

Download and installation of Kubernetes components Docker Desktop forwards this port on the host which facilitates the communication with the control plane as it would be installed directly on the host. Port 6443 is the default port the Kubernetes control plane is bound to. The current-context, user and cluster names are always set to docker-desktop while the global endpoint of the cluster is using the DNS name. It uses Docker Desktop-specific naming and is not customizable by the user. This includes configuration for the cluster’s network topology, certificates, control plane endpoint etc. Docker Desktop takes care of generating these server and client certificates for the main internal services: kubelet (node manager), service account management, frontproxy, api server, and etcd components.ĭocker Desktop installs Kubernetes using kubeadm, therefore it needs to create the kubeadm runtime and cluster-wide configuration. Kubernetes requires certificates and keys for authenticated connections between its internal components, and with the outside. Generating cluster certs, keys and config files The diagram below shows the interactions between the internal components of Docker Desktop for the cluster setup. Installation of additional controllers for networking and storage.

Download and installation of Kubernetes internal components.Generation of certificates and cluster configuration.Internally, the following actions are triggered in the Docker Desktop Backend and VM: What exactly is happening under the hood? Kubernetes can be enabled from the Kubernetes settings panel as shown below.Ĭhecking the Enable Kubernetes box and then pressing Apply & Restart triggers the installation of a single-node Kubernetes cluster. We analyze how Kubernetes is set up to facilitate the deployment of applications, whether they are built locally or not, and the ease of access to deployed applications. This blog post covers development use cases and what happens under the hood for each one of them. Developers can focus entirely on their work rather than dealing with the Kubernetes setup details. It provides a smooth Kubernetes setup experience by hiding the complexity of the installation and wiring with the host. Docker Desktop makes developing applications for Kubernetes easy.
