  • If you don’t want to always open Boot2Docker to interact with Docker, just run the following commands: – – That’s gonna make Docker download the hello-world image from Docker Hub and start a container based on it.
  • In this case, we said, Docker, start a container based on the image hello-world, no extra commands.
  • Then it downloaded the image from Docker Hub and started a container inside the VirtualBox VM based on that image.
  • In the description for the hello-world image, you can find a link to its Dockerfile which only has 3 lines: – – Dockerfiles are just text files containing instructions for Docker on how to build a container image.
  • Let’s remove our old container: – – And let’s run a container based on our new image, connect to it using the -i -t flags, and expose port 8080 of the host (VirtualBox) as the port 3000 of the container (VM): – – Let’s use the express-generator we installed to…

  • Connect your kubectl client to your cluster by running: – – gcloud container clusters get-credentials hello-world-cluster –zone us-east1-b – – So, now we have a docker image and a cluster.
  • Upload Docker Image to Google Container Image Registry – The Google container image registry is a cloud registry where you can push your images and these images automatically become available to your container engine cluster.
  • Lets create one for our first apps/v1beta1 – kind: Deployment – metadata: – name: hello-world-deployment – spec: – replicas: 2 – template: – metadata: – labels: # labels to select/identify the deployment – app: hello-world – spec: # pod spec – containers: – – name: hello-world – image: hello-world-image:v1 #…
  • $ kubectl expose deployment hello-world-deployment –type=LoadBalancer – – Behind the scenes, it creates a service object (a service is a Kubernetes resource, like a Deployment) and also creates a Google Cloud load balancer.
