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?

Replace it with Colima

Point DOCKER_HOST to unix socket of the Docker Daemon.

Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

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

Prerequisites

This guide assumes that you are using the following setup:

Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
Microsoft Windows 7 SP1 as the host OS
A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

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

Architecture principles

From Design It! From Programmer to Software Architect by Michael Keeling.

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.

Set up a role for your lambda that is allowed to assumeRole
Use the AWS SDK to assume the new role in the destination account.
Pass the credentials to the lambda object when you create it
