# Reload nginx every 6h so renewed certs are picked up without downtime.
command: '/bin/sh -c ''while :; do sleep 6h & wait $${!}; nginx -s reload; done & nginx -g "daemon off;"'''
# The nginx:alpine entrypoint only runs its init scripts (including
# template rendering via envsubst) when $1 is `nginx` or `nginx-debug`.
# We override CMD with /bin/sh, so we must render templates ourselves
# before starting nginx. We also keep a 6-hour reload loop so certbot's
# renewed Let's Encrypt certs are picked up without restarting.
