Docker deployment#

Simple#

$ docker run --name snoozeweb -d -p <port>:5200 snoozeweb/snooze

Then the Web interface should be available at this URL:

http://<docker>:<port>

Snoozeweb docker image can be run without any backend database (will default to a file based DB) but if one is needed:

$ docker run --name snooze-db -d mongo

Then

$ export DATABASE_URL=mongodb://db:27017/snooze
$ docker run --name snoozeweb -e DATABASE_URL=$DATABASE_URL \
    --link snooze-db:db -d -p <port>:5200 snoozeweb/snooze

The web interface will listen locally on port 5200: http://localhost:5200

Advanced#

Requirements:

  • Docker (version >= 17.0.0)

  • Docker-Compose

The docker-compose.yaml recipe will create the following (Replace HOST1, HOST2 and HOST3 with swarm workers):

  • 3 nodes MongoDB Replica Set

  • 3 Snooze servers in cluster mode

  • 1 Nginx load balancer (manager node)

After initializing docker swarm and adding workers, run the command:

$ docker stack deploy -c docker-compose.yaml snoozeweb
# Wait until MongoDB containers are up
$ replicate="rs.initiate(); sleep(1000); cfg = rs.conf(); cfg.members[0].host = \"mongo1:27017\"; rs.reconfig(cfg); rs.add({ host: \"mongo2:27017\", priority: 0.5 }); rs.add({ host: \"mongo3:27017\", priority: 0.5 }); rs.status();"
$ docker exec -it $(docker ps -qf label=com.docker.swarm.service.name=snoozeweb_mongo1) /bin/bash -c "echo '${replicate}' | mongo"

The web interface will be available on the manager node on port 80
