Orchestrating with Docker Compose
Launching multiple containers manually can be a hassle, especially when the infrastructure goes increasingly complex. Dependencies, shared variables, and common networking can be easily handled with the orchestration tool named Docker Compose. In a simply YAML file, we can describe what services are needed to run our application (proxy, application, databases, and so on). In this section, we'll show how to create a simple LAMP docker-compose file, then we'll show how we can iterate from that to build some staging and production specific changes.
Getting ready
To step through this recipe, you will need the following:
- A working Docker installation
- A working Docker Compose installation
How to do it…
To orchestrate multiple containers together using Docker Compose, let's start with an easy WordPress example. The team at WordPress built a container that auto-configures to some extent through environment variables similar to what we saw earlier...
