A newsletter that started as a personal learning and getting-in-touch project by Ivan Krnic grew into a sociotechnical newsletter covering topics of technical excellence, organizational improvements, and productivity.
GitOps to the rescue
Years ago, we deployed an application to a cluster of several nodes. Deploying the application was easy, but applying the right configuration to all nodes was difficult. One server ended up with an old configuration, and soon problems started. Although we didn’t end up like Knight Capital Group, it caused us some trouble until we found the cause. That was when I first heard about the “desired state” and GitOps.
GitOps is a set of principles that guide how we manage the desired and actual state (configuration) of our applications. In a nutshell, applications and their state should be:
1. Managed declaratively
2. Versioned and immutable
3. Pulled automatically
4. Continuously reconciled with the desired state
Managing application state this way leads to more frequent deployments, fewer failures, faster recovery from failures, and a happier engineering organization.
And organizations finally have an answer to a million euro audit question: “What is supposed to be deployed and what really is deployed?”
With DORA regulation in place, organizations can’t afford not to use GitOps today.
Listen to my conversation with Dan Garfield on the benefits of GitOps.
