This instructs docker to start building our image from an existing node image based on Alpine Linux. Alpine distribution is the smallest Linux distribution which allows building lightweight images.

Official docker image for node is built from Alpine or Debian [1]

Forgive me if I don't believe that running a full OS on a host OS to run a single node command doesn't amount to running a VM.

This is Node's Docker image.

Since the project is written in Node.js, we need to find a Node.js environment on Docker Hub. We can find the official Node image on Docker Hub by searching for "Node.js".

This node image is just one of a range published by the Node.js team (https://hub.docker.com/_/node), and they also have the Dockerfile for their build available

do you mean container image? npm comes in the "node" container image https://hub.docker.com/_/node

I'm trying to setup a docker container for running a node js app. I'm a bit of a newbie when it comes to docker, but from what I've read all I need to do is "Launch docker image" and enter the image name from the docker repo. In this case: https://hub.docker.com/_/node My config looks like this. After that the UI just says deploying forever. I must be missing something obvious, any ideas?

PostgreSQL

The LMS Moodle Operator serves as a meta-operator, orchestrating the deployment and management of Moodle instances in Kubernetes. It handles the entire stack required to run Moodle, including components like Postgres, Keydb, NFS-Ganesha, and Moodle itself. Each of these components has its own Kubernetes Operator, ensuring seamless integration and management.

Another key feature of txtai is being able to quickly move from prototyping to production. This article will demonstrate how txtai can integrate with Postgres, a powerful, production-ready and open source object-relational database system. After txtai persists content to Postgres, we'll show it can be directly queried with SQL from any Postgres client

SQL (Structured Query Language) databases are relational databases. They organize data into tables with rows and columns, and they use SQL for querying and managing data. Examples include MySQL, PostgreSQL, and SQLite.

Node.js, MySQL and PostgreSQL servers installed on your machine

Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).

I've used MySQL for years. But recently, I found myself working PostgreSQL and simple things like dumping and restoring a database are different enough that I decided to document the process. It's straightforward enough once I knew how.

A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:
