The web service builds from the Dockerfile in the current directory. Next when docker ps was run. A Dockerfile and a context.

To allow external access to Docker containers you would have to expose their ports by mapping a containers port to an external port in the host. Forwards the containers exposed port 5000 to port 5000 on the host Mounts the project directory on the host to code inside the container allowing you to modify the code without having to rebuild the image. After successfully building the image the next step is to run an instance of the image.

Two Kubernetes services will also be created for us to access the deployed application. We can access the application using the command below. When that container was created the -P flag was used to automatically map any network port inside it to a random high port within an ephemeral port range on your Docker host.

Now all we have to do is to tell Docker what command we want to run when our image is executed inside a container. Docker run -p 50005000 -d flask_docker. Docker build --tag flask-test-applatest.
