How to Dockerize a Go Application – Full Step-by-Step Walkthrough
Docker allows developers to package applications and their dependencies into containers, ensuring consistent behavior across different environments. This article provides a beginner-friendly guide to dockerizing a Go application using Docker and Docker Compose. It covers creating Dockerfiles, setting up containers for an app and database, and orchestrating multi-container applications.
- ▪Docker solves the 'it works on my machine' problem by containerizing applications with all their dependencies.
- ▪A Dockerfile contains instructions for building a Docker image, which can be used to create runnable containers.
- ▪Docker Compose enables managing multiple interdependent containers, such as an application, a database, and phpMyAdmin, through a single configuration file.
- ▪The article walks through setting up a Go application in a container, along with a database and phpMyAdmin container for development.
- ▪No prior Docker knowledge is required, though basic familiarity with Go is helpful for following the examples.
