How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

  1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
  2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
  3. VPC with NAT, The best of both worlds, AWS services and web.

mervintankw / Using Github with Two Factor Authentication.md
Created April 26, 2020 09:22 — forked from trevorlinton/Using Github with Two Factor Authentication.md

Using Github with Two Factor Auth.

It's a fairly common complaint that after enabling github two factor authentication that command line utilities stop working. The underlying issue is command line utilities send your username and password with each request to github, using two factor authentication disables github from accepting just your username and password, so your command line utilities such as git appear to stop working. Github will still accept a personal access token instead of your password however.

Re-enabling your command line utilities (OSX)
