Often we don't want to run just one container at a time, but a set of containers that act together to provide a unit of functionality. Yet, docker run only starts one container at a time, with one command in each container at a time.
Docker Compose lets us overcome this limitation by allowing us to define a single file that describes multiple containers, their relationship to each other, and utilities to manage that set of containers as a single unit.
In this tutorial, we'll:
- Introduce Docker Compose
- Run multiple containers at once using Docker Compose
- Identify the purpose of docker-compose.yml
- Learn what resources a set of containers share
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
