Launch_Alpine_Linux_3.3.x_on_AWS.md

Create a local VM of Alpine Linux, eg: https://gist.github.com/kennwhite/959d47a77070d365ad60

• On your workstation open a terminal and create a new ssh keypair:

  ssh-keygen -t rsa -b 4096 -C "alpine@example.com"

  • Set a meaningful keypair base file name when prompted, eg: alpine-test
