# PhotoPrism Cloud Init Script
# ============================
#
# Put this script in
#
#   /var/lib/cloud/scripts/per-instance
#
# so that it runs once when the server is booting for the first time:
#
#   cd /var/lib/cloud/scripts/per-instance
#   curl -fsSL https://dl.photoprism.app/cloud/digitalocean/install_photoprism.sh > install_photoprism.sh
#   chmod 700 install_photoprism.sh
#
# To create a reusable image for DigitalOcean:
#
#   packer init digitalocean.pkr.hcl
#   packer build digitalocean.pkr.hcl
#
# Download packer from https://developer.hashicorp.com/packer/install if not installed yet.
#
# Enjoy!
