Operations grimoire/Sentry

Sentry is deployed on docker-002 through the Docker PaaS.

The Sentry DSN or the humans UI can be reached at https://sentry.nasqueron.org

Command line

Sentry provides a command line interface.

To use it, log in to docker-002, then run sentry nasqueron <command>. It will then spawn a new container correctly linked to the database, SMTP server and PostgreSQL database to run it. TODO: update the sentry wrapper to use the sentry network and get the right environment instead.

If you've deployed another instance than for Nasqueron, replace it by the realm name.

Kafka and ZooKeeper

• Deployment pitfall: ZooKeeper wants a clean log if you initialise it, if not it will shutdown. Ensure it has always a data volume or an empty log when starting it.

• Kafka has a 20 seconds pause before initializing the topics, to let the cluster correctly start.

To reprovision Kafka and ZooKeeper from scratch, the following works fine:

$ rm -rf /srv/kafka/sentry_kafka /srv/zookeeper/sentry_zookeeper
$ deploy-container zookeeper
$ deploy-container kafka
