+# Nestybox's Drone system-container dockerfile.
+#
+# Description:
+#
+# Image's purpose is to provide a full-fledge Drone CI/CD system. Obtained image
+# will incorporate all the necessary Drone binaries, as well as the dockerd
+# binary required to instantiate 'inner' containers. Both daemons will be managed
+# through supervisord process manager.
+#
+# Requirements:
+#
+# A supervisord.conf file in charge of launching dockerd & drone-server daemons,
+# must be provided as part of this docker image compilation process. See example
+# below:
+#
+# ---
+# $ cat supervisord.conf
+# [supervisord]
+# stdout_logfile=/dev/stdout
+# stdout_logfile_maxbytes=0
+# nodaemon=true
+#
+# [program:dockerd]
+# command=/usr/bin/dockerd
+# priority=1
+# autostart=true
+# autorestart=true
+# startsecs=0
+#
+# [program:drone-server]
+# command=/bin/drone-server
+# priority=2
+# autostart=true
+# autorestart=true
+# startsecs=0
+# ---
+#
+# Container initialization:
+#
+# $ docker run --runtime=sysbox-runc \
+#  --env=DRONE_GITHUB_SERVER=https://github.com \
+#  --env=DRONE_GITHUB_CLIENT_ID=${DRONE_GITHUB_CLIENT_ID} \
+#  --env=DRONE_GITHUB_CLIENT_SECRET=${DRONE_GITHUB_CLIENT_ID} \
+#  --env=DRONE_RUNNER_CAPACITY=2 \
+#  --env=DRONE_SERVER_HOST=${DRONE_SERVER_HOST} \
+#  --env=DRONE_SERVER_PROTO=https \
+#  --env=DRONE_TLS_AUTOCERT=true \
+#  --env=DRONE_SERVER=http://${DRONE_SERVER_HOST} \
+#  --env=DRONE_TOKEN=${DRONE_TOKEN} \
+#  --env=DRONE_USER_CREATE=username:nestybox,admin:true,token:${DRONE_TOKEN} \
+#  --publish=80:80 --publish=443:443 \
+#  -d --rm --name=drone nestybox/ubuntu-bionic-docker-drone
