Docker allows you to package Node.js applications along with their dependencies into lightweight containers, ensuring consistency across development, testing, and production environments. This guide covers creating a Dockerized Node.js application, writing a Dockerfile, running the container, and sharing ...
We introduced the Node Docker Official Image (DOI) due to Node.js’ popularity and to solve some common development challenges. The Node.js Foundation describes Node as“an open-source, cross-platform JavaScript runtime environment.” Developers use it to create performant, scalable server and ...
In this tutorial, you will create an application image for a static website that uses theExpressframework andBootstrap. You will then build a container using that image and push it toDocker Hubfor future use. Finally, you will pull the stored image from your Docker Hub repository and build ...
Because the Node.js barcode reader app relies onlibDynamsoftBarcodeReaderx64.so, you need to use the Docker instruction “**COPY**" to add the shared library to the filesystem of the container: COPYlibDynamsoftBarcodeReaderx64.so /usr/lib/libDynamsoftBarcodeReaderx64.so ...
This uses Express to set up a server with some endpoints as well as the winston logger that forwards the logs to the console. We’ll use the following Dockerfile for this application: Dockerfile FROM node:14-alpine ENV HOST='0.0.0.0' ENV PORT=8080 RUN addgroup app && adduser -S -G...

Usingfnm, we can create a Dockerfile that gives rise to a Node.js image. But first, what isfnm?fnm(short for Fast Node Manager) is a tool for installing and managing Node.js. We’ll start withubuntu:24.04(a random choice) as our base image: ...

In this post, we will design a Node.js client that could be used to safely store select fields as part of a medical application. The Requirements There are a few requirements that must be met prior to attempting to use Client-Side Field Level Encryption (CSFLE) with the No...
Installing Docker now gives you not just the Docker service (daemon) but also thedockercommand line utility, or the Docker client. We’ll explore how to use thedockercommand later in this tutorial. Step 2 — Executing the Docker Command Without Sudo (Optional) ...
