![]() Tip: minikube is a cheap and easy way to set up a single node Kubernetes cluster Proceed by installing the helm command line tool and execute the helm init command to initialize Helm. In the next section we’ll create a chart to deploy our application image on a Kubernetes cluster.īefore continuing, create a Kubernetes cluster using the solution of your choice. A package in Helm is referred to as a chart. Helm is a package manager for Kubernetes. It is quickly becoming the de facto standard for deploying and managing containerized applications at scale. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Unlike the docker-compose.yaml file used during the application development, the does not mount a volume at /app as the application source is copied into the image during the image build.ĭeploy the application using the command docker-compose -f up and access the application at Create a Helm Chart ![]() A Dockerfile is also generated which can be used to build a application image for production deployments. The container sees that the /app directory is empty and uses express-generator to bootstrap a new express application. The compose spec mounts the current working directory as a volume ( at the /app path) of the express container. $ curl -o docker-compose.yaml $ docker-compose up -d Next, use the VSCode shortcut Command+` to open a terminal and execute the following commands to download and launch the docker-compose.yaml. To bootstrap a Express application create a directory named myapp and open it in VSCode. For our application we will use MongoDB for the application database. The GitHub repository provides a few Docker Compose files, pre-configured to get you started developing applications with the database backend of your choice. ![]() The Bitnami Express development container is engineered to provide a highly reproducible Node.js + Express runtime for development and production environments. We will make use of the Docker and vs-helm extensions, please ensure you have these installed. Open-sourced by Microsoft VSCode is a free and extensible text editor with a thriving marketplace for third party extensions. We use the Visual Studio Code (or VSCode) text editor for developing the application. The Introduction to Express tutorial is a good resource to familiarize yourself with Express. The post requires that the reader has basic knowledge of developing applications with Express and Node.js. We’ll conclude by creating a Helm chart and deploy the application image to a Kubernetes cluster. In this post we’ll look at the workflow for developing an Express application using the Bitnami Express development container and Visual Studio Code. It’s a free and open-source framework released under the MIT License and is developed and maintained by the Node.js foundation. Application development with Bitnami Express container and VScode IntroductionĮxpress is a minimalist web application framework for Node.js.
