This week’s spotlight on CoreOS rkt, a secure container engine, explores how rkt can fetch and run Docker container images, and how you can take advantage of this to run containers from any Docker registry with rkt, without needing to rebuild or convert them manually.

Prometheus is an open source monitoring and alerting system. Its powerful query language used to retrieve time series data can also be employed when defining alerts. Alerts actively notify users of irregular system conditions, sending messages to a variety of integrations such as Slack or PagerDuty.
