In this part of the series, I’m going to add Sentry to the monitoring stack. For those who do not know, Sentry is an open-source cross-platform crash reporting and aggregation platform written in Python. I know about it for several years now, since the time it supported only a few languages. A lot has changed since my last use of it: new domain, new languages, new integrations. Today it has integrations with most of the modern languages and frameworks like Elixir, React, React-Native, Go.

Generation of sitemaps is usually not a problem, at least not until you have several millions of items in the database to iterate through. Currently, I have slightly more than 4M documents, so it takes time to regenerate. Previously all my sitemaps were stored on the disk and were served using simple Nginx container. It worked like this: Sitemap-related containers have nodeSelector to assign to particular node with hostPath volume sitemaps are served from /data/sitemaps folder periodic task generates new sitemaps to /data/sitemaps-temp on completion, folders is atomically switched It was fine in my previous VM-based cluster, which was on a single physical machine.
