Addressing slow builds

[kaihendry]

Love devcontainers, but I find them really slow for the initial build! Any tips?

// For format details, see https://aka.ms/devcontainer.json. For config options, see the
// README at: https://github.com/devcontainers/templates/tree/main/src/universal
{
	"name": "Default Linux Universal",
	// Or use a Dockerfile or Docker Compose file. More info: https://containers.dev/guide/dockerfile
	"image": "mcr.microsoft.com/devcontainers/universal:2-linux",
	"features": {
		"ghcr.io/devcontainers/features/aws-cli:1": {},
        "ghcr.io/devcontainers-extra/features/aws-cdk:2": {}
	},

	// Features to add to the dev container. More info: https://containers.dev/features.
	// "features": {},

	// Use 'forwardPorts' to make a list of ports inside the container available locally.
	// "forwardPorts": [],

	// Use 'postCreateCommand' to run commands after the container is created.
	"postCreateCommand": ".devcontainer/create-command.sh",

	// Configure tool-specific properties.
	// "customizations": {},

	// Uncomment to connect as root instead. More info: https://aka.ms/dev-containers-non-root.
	// "remoteUser": "root"
}
