PASSWORD=$(head -c18 /dev/urandom | base64)

# First, set up DNS for both relay.$SUBDOMAIN and $SUBDOMAIN, otherwise certbot will fail

# Add user
adduser $SUBDOMAIN
echo $SUBDOMAIN:$PASSWORD | chpasswd

# Create database
sudo -u postgres createdb $SUBDOMAIN;
sudo -u postgres psql -c "CREATE USER \"$SUBDOMAIN\" WITH PASSWORD '$PASSWORD';"

# Log in as user
SUBDOMAIN=$SUBDOMAIN PASSWORD=$PASSWORD PORT=$PORT su $SUBDOMAIN

# Go to home dir
cd ~

# Install nvm, yarn, clone repos
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
. ~/.bashrc

# Clone repos
git clone https://github.com/coracle-social/coracle.git
