# ==== CREATING USERS AND LOGGING IN TO rollout ====
# https://github.com/rollout/rollout/wiki/Adding-users
#---------------------------------------------------------------------------------------------------------
# ==== FORGOT PASSWORD ====
# https://github.com/rollout/rollout/wiki/Forgot-Password
#---------------------------------------------------------------------------------------------------------
# ==== Upgrading rollout to new version =====
# NOTE: MongoDB has changed from 3.x to 4.x, in that case you need backup/restore with --noIndexRestore
#       see https://github.com/rollout/rollout/wiki/Backup
# 1) Stop rollout:
#      docker-compose stop
# 2) Download new version:
#      docker-compose pull rollout
# 3) If you have more networks for VPN etc as described at bottom of
#    this config, download for them too:
#      docker-compose pull rollout2
# 4) Start rollout:
#      docker-compose start
#----------------------------------------------------------------------------------
# ==== OPTIONAL: DEDICATED DOCKER USER ====
# 1) Optionally create a dedicated user for rollout, for example:
#      sudo useradd -d /home/rollout -m -s /bin/bash rollout
# 2) Add this user to the docker group, then logout+login or reboot:
#      sudo usermod -aG docker rollout
# 3) Then login as user rollout.
# 4) Create this file /home/rollout/docker-compose.yml with your modifications.
#----------------------------------------------------------------------------------
# ==== RUN DOCKER AS SERVICE ====
# 1a) Running Docker as service, on Systemd like Debian 9, Ubuntu 16.04, CentOS 7:
#      sudo systemctl enable docker
#      sudo systemctl start docker
# 1b) Running Docker as service, on init.d like Debian 8, Ubuntu 14.04, CentOS 6:
#      sudo update-rc.d docker defaults
#      sudo service docker start
# ----------------------------------------------------------------------------------
# ==== USAGE OF THIS docker-compose.yml ====
# 1) For seeing does rollout work, try this and check with your webbroser:
#      docker-compose up
# 2) Stop rollout and start rollout in background:
#     docker-compose stop
#     docker-compose up -d
# 3) See running Docker containers:
#     docker ps
# 4) Stop Docker containers:
#     docker-compose stop
# ----------------------------------------------------------------------------------
# ===== INSIDE DOCKER CONTAINERS, AND BACKUP/RESTORE ====
# https://github.com/rollout/rollout/wiki/Backup
# If really necessary, repair MongoDB: https://github.com/rollout/rollout-mongodb/issues/6#issuecomment-424004116
# 1) Going inside containers:
#    a) rollout app, does not contain data
#         docker exec -it rollout-app bash
#    b) MongoDB, contains all data
#         docker exec -it rollout-db bash
# 2) Copying database to outside of container:
#      docker exec -it rollout-db bash
#      cd /data
#      mongodump
#      exit
#      docker cp rollout-db:/data/dump .
# 3) Restoring database
#      # 1) Stop rollout
#             docker stop rollout-app
#      # 2) Go inside database container
#             docker exec -it rollout-db bash
#      # 3) and data directory
#             cd /data
#      # 4) Remove previos dump
#             rm -rf dump
#      # 5) Exit db container
#             exit
#      # 6) Copy dump to inside docker container
#             docker cp dump rollout-db:/data/
#      # 7) Go inside database container
#             docker exec -it rollout-db bash
#      # 8) and data directory
#             cd /data
#      # 9) Restore
#             mongorestore --drop
#      # 10) Exit db container
#             exit
#      # 11) Start rollout
#             docker start rollout-app
