Docker Intro

• An image is a set of instructions, and the environment you get after running the instructions.
• A container is a command running in an image.

Analogy: an image is the Ikea instructions for building shelves, and the assembled shelves, before you start using them.

A container is the shelves in-use, with books on them etc.

GraphQL Intro

3 Core Concepts:

• Types: What kinds of things are returned by the API?
• Schema: How can the API be queried, and how are the types related to each other?
• Requests: What does a GraphQL API request look like?
• Resolvers: How does GraphQL get the data from the data source?
