Containerization of apps is a fast-growing practice as many companies are embracing the cloud and DevOps concepts. Docker packages an application, libraries, and its dependencies in a virtual container that can run on any server. Being that most applications do not run on one single component (even dinosaur apps 🦖 have frontend and backend components), we need a way to define and manage multi-container apps.
In this tutorial I will utilize Docker compose to get a blog up and running that consists of a Ghost Blog service and a MYSQL service; both services will use volumes for persistent storage. This tutorial assumes you have working knowledge of Docker and a server with Docker and Docker compose installed.
What is Docker Compose?
Compose is a file format for describing distributed Docker apps, and it’s a tool for managing them.
What is Ghost?
Let’s go! 🐳
Step 1 — Login to the server and become root
1. SSH into the server and become root
sudo su -
Step 2 — Create a Ghost Blog and MySQL service
2. Create a
docker-compose.yml file in the root directory
Add the following contents
Step 3 — Start up the Docker compose service and Bring up the Ghost Blog
docker-compose up -d
Congrats your blog is up and running! Validate via the public IP address of your Docker server.
