Great blog and site, thanks for all the time spent on these!! Summary Now I have two running network services inside the Kubernetes cluster.

Export strips fields that a user can not specify. Useful when you want to manage related manifests organized within the same directory. We assume you have read the , and understand what the different components of a Dotmesh cluster are.

Kubernetes deployment specification

In this tutorial, I aim to simplify things a bit for you by using the basic idea of building a Python application with Docker and deploying kubernetes yaml reference to a Kubernetes service. In one line, we will have a base Ubuntu image with Python 2. There are tons of images on DockerHub, but if you would like to start off with a fresh Ubuntu image and build on top of it, you could do that. Thus, if you want to clone your git repository instead of copying it from your local repository for staging and production purposesyou can use that. Show more Show more icon Build an image from the Dockerfile Open the terminal and type this command to build an image from your Dockerfile: docker build -t : Run your container locally and test After you build your image succesfully, type: docker run -d -p 5000:5000 app This command will create a container that contains all the application code and dependencies from the image and runs it locally. In this case, we simply select on one label defined in the Pod template app: flasknode. However, more sophisticated selection rules are possible, as long as the Pod template itself satisfies the rule. Explanation and breakdown of the service. By default the targetPort will be set to the same value as the port field. Perhaps kubernetes yaml reference interesting is that targetPort can be a string, referring to the name of a port in the backend Pods. The actual port number assigned to that name can be different in each backend Pod. This offers a lot of flexibility for deploying and evolving your Services. For example, you can change the port number that pods expose in the next version of your backend software, without breaking clients.

For all those who used docker-compose and similar tools, sometimes having environment files is crucial to keep docker-compose. Pulumi is different, in that it lets you use your favorite languages. Export strips fields that a user can not specify. I think the term service is an unfortunate but probably unavoidable terminology overload. Pods created by a ReplicationController. Exact export maintains cluster-specific fields like 'Namespace' false boolean PathParameter namespace object name and auth scope, such as for teams and projects true string PathParameter name name of the ServiceAccount true string Parameters Type Name Description Required Schema Default QueryParameter pretty If 'true', then the output is pretty printed. Useful when you want to manage related manifests organized within the same directory. If set to true, record the command.
