Ubuntu in a box (multipass)

Ubuntu in a Box using multipass

  1. Export the following variables
export GIT_USER_NAME=...
export GIT_USER_EMAIL=...
  1. Launch and configure the instance
multipass launch --name ubuntu --mem 2G

wget -qO- https://gist.githubusercontent.com/leandronsp/aa034b6bec7b24718ab915fec5e95512/raw/a33ada9c7b2a0bfdd025f3fb85d0d376b08f00be/configure | xargs -I{} multipass exec ubuntu -- bash -c {} 

multipass exec ubuntu -- bash -c "git config --global --replace-all user.email $GIT_USER_EMAIL"

multipass exec ubuntu -- bash -c "git config --global --replace-all user.name $GIT_USER_NAME"

multipass exec ubuntu -- bash -c "ssh-keygen -t rsa -b 4096 -C $GIT_USER_EMAIL -N '' -f ~/.ssh/github_rsa"

multipass exec ubuntu -- bash -c "cat ~/.ssh/github_rsa.pub"

Then copy the SSH key from the output (ssh-rsa...) and paste it to your Github SSH Keys settings.

  1. Configure dotfiles
multipass exec ubuntu -- bash -c 'echo "eval \$(ssh-agent -s)" >> ~/.bashrc'

multipass exec ubuntu -- bash -c 'echo "ssh-add ~/.ssh/github_rsa" >> ~/.bashrc'
