Output: NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE hello-node 1 1 1 1 23h This is good since we haven’t pushed it there! kubectl run hello-node -image=hello-node:v1 -port=8080 -image-pull-policy=Never Set the -image-pull-policy flag to Never this will mean that it will always use the local image, rather than pulling it from your Docker registry. The Pod runs a Container based on your hello-node:v1 Docker image. We can use the kubectl run command to create a Deployment that manages a Pod.
Deployments are the recommended way to manage the creation and scaling of Pods. The Pod in this tutorial has only one Container.Ī Kubernetes deployment runs a health check on of your Pod and restarts the Pod’s Container if it terminates for any reason. Now the Minikube VM can run the docker image you have built.Ī Kubernetes pod is a group of one or more Containers joined together for networking. Note: Later, when you no longer wish to use the Minikube host, you can undo this change by running: eval $(minikube docker-env -u).īuild your Docker image, using the Minikube Docker daemon (mind the trailing dot): docker build -t hello-node:v1. To do this we need to make sure we are using the Minikube Docker daemon, you can do this by running the following: eval $(minikube docker-env ) This Dockerfile image starts by using the necessary Node.js image found in the Dockerhub registry, it then exposes port 8080, copies your server.js file to the image and runs the command that starts the Node.js server.īecause this tutorial uses Minikube, instead of pushing your Docker image to a registry, you can simply build the image using the same Docker host as the Minikube VM, so that the images are automatically present. FROM node:6.9.2 EXPOSE 8080 COPY server.js. In this file, we shall then paste the following commands for our Dockerfile image. To create your Dockerfile we will stay in the hellonode folder, and create a file named “Dockerfile” using your favourite text editor. The image in this tutorial extends an existing Node.js image which we have just built. You can build a Docker container image by extending an existing image. A Dockerfile describes the image that you want to build such as language version, ports being used etc. To do this we will first need to create a Dockerfile. The next step we can do is to package your application in a Docker container for easy distribution. Now that we have correctly configured Minikube to run Kubernetes locally we can open the Kubernetes dashboard in a browser using the following command which will open a browser window with your dashboard: minikube dashboard This will output the following if correctly running: Kubernetes master is running at KubeDNS is running at :8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
We should then verify that kubectl is configured to communicate with your cluster: kubectl cluster-info To set the context to use minikube we will use the following command: kubectl config use-context minikube You can see all your available contexts in the ~/.kube/config file. The context is what determines which cluster kubectl is interacting with. Now we will need to set the Minikube context.

The default VM driver for Minikube is VirtualBox.
The -vm-driver=hyperkitflag specifies that you are using Docker for Mac. if you are blocked by a corporate network etc, you can use the following method to start Minikube cluster with proxy setting: minikube start - vm-driver=hyperkit - docker-env HTTP_PROXY= - docker-env HTTPS_PROXY=http(s)://your-https-proxy-host:your-https-proxy-port If NO proxy is required, start the Minikube cluster: minikube start - vm-driver=hyperkit You can determine if docker is running by using a command such as: docker images We then make sure that the Docker daemon is started.

Use Homeb rew to download the kubectl command-line tool, which you can use to interact with Kubernetes clusters: brew install kubernetes-cliĭetermine whether you can access sites like directly without a proxy, by opening a new terminal and using: curl -proxy “” Now that we have our prerequisites complete lets get started with Minikube.įirst, we use Homebrew to install the latest Minikube release: brew cask install minikube If you don’ t have docker installed you can easily install it using the install package provided by Docker here: If you are on a different platform like Linux or using VirtualBox instead of Docker for Mac, the instructions to install Minikube may be slightly different. This tutorial uses Docker for Mac as the host of Minikube. This tutorial uses Minikube to create a local kubernetes cluster.
