Docker Swarm VS ama

Docker - A containerization platform that allows developers to package applications and their dependencies into containers. Docker Compose can be used to define multi-container application stacks, including web servers, databases, and other services. Features powerful portability and consistency, supports rapid building, sharing, and container management, suitable for complex application architectures, and requires a learning curve.

This article wanted to be a brief and gentle introduction to the container and docker world, there is a lot more to learn so don’t hesitate to check the docker documentation.

It appears they have since reverted the decision but it used to require logging in:

Docker Documentation

Docker is a tool that can help the developer to run each dependency in containers. Find more about Docker at Docker Official.

According to Docker Docs, a Dockerfile is a text document that contains all the instructions a user could call on the command line to assemble an image. These instructions include actions like installing software, copying files, setting environment variables, and defining how an application should run.

Hello reader, it's Sourab here. Recently in one of my projects I used Docker and Nginx for deploying a React App to a front-end server. Let's see how I did it.

Composer is not meant to run in production. It is only meant for development or building images. Make sure to read Getting started with swarm mode and check this if you want to use run your build image on a proper environment. (recommended)

I don't know if I would call myself an expert, but worrying about security is a big concern of mine and my job. While there are some security benefits to running your app in a container, you're correct in thinking there are some things to keep in mind while writing your Dockerfiles and using Docker. Check out Bret Fisher's write up on security concerns using Docker. This is the second time that I've mentioned him. He's a Docker Captain and recognized by Docker as an expert. His advice is sound.

Only one host for production environment. What to use: docker-compose or single node swarm? · Issue #8 · BretFisher/ama (github.com)
