Building an image in kubernetes using Kompose

Question

I have installed Kompose which is the conversion tool for translating the docker compose file to kubernetes resource. How do i build and push docker images? Please help.

Kompose supports both building and pushing Docker images. 

When using the build key within your Docker Compose file, your image will:

• Automatically be built with Docker using the image key specified within your file
• Be pushed to the correct Docker repository using local credentials (located at .docker/config)

Using a sample docker-compose file:

version: "2"

services:
    foo:
        build: "./build"
        image: docker.io/foo/bar

Using kompose up with a build key:

$ kompose up
INFO Build key detected. Attempting to build and push image 'docker.io/foo/bar'
INFO Building image 'docker.io/foo/bar' from directory 'build'
INFO Image 'docker.io/foo/bar' from directory 'build' built successfully
INFO Pushing image 'foo/bar:latest' to registry 'docker.io'
INFO Attempting authentication credentials 'https://index.docker.io/v1/
INFO Successfully pushed image 'foo/bar:latest' to registry 'docker.io'
INFO We are going to create Kubernetes Deployments, Services and PersistentVolumeClaims for your Dockerized application. If you need different kind of resources, use the 'kompose convert' and 'kubectl apply -f' commands instead.

INFO Deploying application in "default" namespace
INFO Successfully created Service: foo            
INFO Successfully created Deployment: foo         

Your application has been deployed to Kubernetes. You can run 'kubectl get deployment,svc,pods,pvc' for details.
