About Argo CD​

Argo CD is a GitOps continuous delivery tool for Kubernetes, which continuously monitors all the running applications and compares the live state with the desired state specified in the Git repo. Argo CD automates the deployment of the desired application states in the specified target environments. Application deployments can track updates to branches, tags, or pinned to a specific version of manifests at a Git commit.

A deployed application whose live state deviates from the target state is considered OutOfSync.
