AWS SAM local commands without Docker Desktop

AWS SAM local commands check for the existance of DOCKER_HOST. If the variable is not present, it will fail with the following error message

Error: Running AWS SAM projects locally requires Docker. Have you got it installed and running?

Point DOCKER_HOST to unix socket of the Docker Daemon.

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

This guide assumes that you are using the following setup:

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

Partition system and assign responsibilities.
Decide trade-offs among quality attributes:
- Performance (response time)
- Scalability (annual growth)
- Availability
- Security

Set up a cross-account IAM role in the destination account

Add a new IAM role
For type of trusted entity select "another AWS account"
Specify the accountId of the account that will be using the resource in the destination account. You can find your AWS Account ID, which is available on the support homepage when you are logged in.
Create a policy that allows lambda:InvokeFunction for your function and attach it to this new role.

Create a lambda in the calling account.

To install the needed components you can use Homebrew
