Customise AWS cloudshell or Amazon Linux 2 with nice utilities
# Note for Cloudshell, only stuff in your home directory is saved.
# But, Cloudshell already has git and zsh available. So we just install custom binaries to ~/bin and update our path.
# you can whoami == cloudshell-user or $AWS_EXECUTION_ENV==CloudShell to detect cloudshell
# Start zsh on startup. No chsh :(
[[ $AWS_EXECUTION_ENV == "CloudShell" ]] && echo "In CloudShell, no need to install git/zsh" || sudo yum -y install git zsh && echo zsh >> ~/.bashrc
echo 'alias l="ls -lash"' >> ~/.zshrc

`Failed to delete stack: Role <role> is invalid or cannot be assumed` Assume this role from the cli if your cloudformation stack can't delete

Create a role with a trust policy that can be assumed by Cloudformation. Trust policy looks like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
 "Effect": "Allow",
