Replace the DOCKER-USERNAME placeholder in the command below with your Docker account username.ĭocker build -t DOCKER-USERNAME/myapp:1.0. In this case, the npm start will start the application.īuild the image using the command below. The CMD instruction specifies the command to run when the image starts.Learn more about Bitnami's non-root containers. For security reasons, it's recommended to always run your application using a non-root user account. The RUN commands create a non-root user account that the application will run under.

The COPY instruction copies the source code and installs dependencies from the first stage to the /app directory in the image.

Bitnami production images can be identified by the suffix prod in the image tag.

Since the target here is a minimal, secure image, the FROM instruction specifies Bitnami's Node.js production container as the base image.

Here is what happens in the second build stage:

The WORKDIR instructions set the working directory for the image.

It's used to run npm install to install the application dependencies.

The RUN instruction executes a shell command.

The COPY instruction copies the source code from the current directory on the host to the /app directory in the image.

The NODE_ENV environment variable is defined so that npm install only installs the application modules that are required in production environments.

Since the example application used in this guide is a Node.js application, Bitnami's Node.js development container is the best choice for the base image. Bitnami offers several container images for Docker which can be used as base images.

The FROM instruction kicks off the Dockerfile and specifies the base image to use.

Let's take a closer look at the steps in the first build stage: It is therefore lighter and smaller in size than the development image and is commonly used in multi-stage builds as the final target image.

The production image (tagged with the suffix prod) is based on minideb and does not include additional development dependencies. Tip: Bitnami's Node.js production image is different from its Node.js development image.

The second stage uses the Bitnami Node.js 14.x production image and creates a minimal Docker image that only consists of the application source, modules, and Node.js runtime.

The first stage uses the Bitnami Node.js 14.x development image to copy the application source and install the required application modules using npm install.

This Dockerfile consists of two build stages: Follow the steps below:īegin by creating a directory for your application and making it the current working directory:Ĭreate a package.json file listing the dependencies for the project: The first step is to create a simple Express application. If you are using a MEAN application, you may need to adapt the MongoDB connection string in the application source code as explained in our MEAN tutorial. Tip: If you already have an Express application, you can use that instead and skip to Step 2. Learn more about getting started with Kubernetes and Helm using different cloud providers.

You have a Kubernetes cluster running with Helm v3.x and kubectl installed.

You have a Docker environment installed and configured.

This guide makes the following assumptions: This article walks you through the process of developing a basic Node.js/Express application, deploying it on Kubernetes with Bitnami's Node.js container image and Helm chart, and monitoring errors thrown by it in real-time with Sentry.

Together, this combination gives enterprise developers all the tooling they need to create and publish applications consistently, monitor and debug errors in those running applications, and release new and improved versions on an iterative basis. Bitnami offers a curated catalog of secure, optimized, and up-to-date containers and Helm charts for enterprises to build and deploy applications across platforms and cloud vendors. Sentry is a popular cloud-based framework that helps developers diagnose and fix application errors in real-time. These tools also need to enable the swift deployment of patches and updates to your applications. That's why tools that quickly identify and debug errors are critical in a continuous deployment environment.

No matter the size of your development team or the scale at which it operates, bugs are inevitable in software development.
