About Argo CD

Argo CD applies GitOps principles to continuous delivery on Kubernetes, in a declarative way. Its premise is that application definitions, configuration and environments should be declarative and version controlled, and that rolling out and managing applications should be automated, traceable and straightforward. It is written in Go, is part of the Argo project under the CNCF, and is released under the Apache-2.0 license.

Repository topics show support for Helm, Kustomize and Jsonnet as ways to describe applications, alongside a focus on continuous deployment pipelines. The project offers complete documentation and a live demo, and the community can be reached through GitHub Discussions, a Slack channel, contributor office hours and monthly user community meetings. Its README links to many blog posts and talks on combining Argo CD with tools such as Crossplane, Argo Workflows and preview environments for pull requests.
