This mind map serves as a comprehensive guide to Docker usage and commands, focusing on Docker Compose, volumes, and container management. It covers how to handle .env files, recreate specific containers, and manage data persistence with host volumes, anonymous volumes, and named volumes (recommended for production). The map also provides examples of Docker Compose configurations and details on running Nx with Docker. Key Docker commands are included for starting, stopping, building, and mon...

2.2. volumes
2.2.1. for data presistence
2.2.1.1. connectiong the host file system to a virtual directory of container file system
2.2.2. types
2.2.2.1. Host volume
2.2.2.1.1. we define the absolute path of host directory to the virtual path inside the container
2.2.2.2. Anonymous volume
2.2.2.2.1. docker create a volume for us and mount it the virtual path inside the container
2.2.2.3. named volumes
2.2.2.3.1. docker create a volume with a name which is given by us. Then it mounts this volume to the virtual path inside the container
2.2.2.3.2. This is the type that we should use the most in production
2.2.3. Docker compose example for named volumes
2.2.4. relative paths
2.2.4.1. the path that docker compose exist
2.3. Nx
