Technical requirements

Throughout this chapter, we will use Docker to provision databases in containers. Using a database container is common when building scalable and resilient architectures – particularly when using a container orchestrator such as Kubernetes.

However, the main reason why we’ll be using Docker containers throughout this chapter is to save us from having to manually install each of the database command-line interfaces (CLIs) and servers onto our system. In this chapter, we will be using Docker to provision containerized MySQL, PostgreSQL, MongoDB, and Redis data stores.

It is recommended to install Docker Desktop from https://docs.docker.com/engine/install/.

If you are unable to install Docker, then you can still complete the recipes, but you will need to manually install the specific databases for each recipe or connect to a remote database service.

Note that this chapter will not cover how to enable persistent data storage from Docker...
