Project history

The cilium/tetragon repository was created in March 2022. Its README describes Tetragon as a Cilium component for real-time, eBPF-based security observability and runtime enforcement, with Kubernetes-aware event detection.

The official release list includes a Tetragon CLI release in May 2022, a v0.8.0 release shortly afterward, and v1.0.0 in November 2023. The tetra CLI became the local operator and developer interface for observing, managing, and troubleshooting Tetragon installations.

Adoption history

Tetragon adoption is centered in the cloud-native security and observability community. The official USERS.md invites production users to list themselves and includes adopters using Tetragon for runtime security, process/file/network observability, Kubernetes security, and artifact attestation use cases.

For package-manager users, the tetra formula is useful because it installs just the client binary needed to interact with Tetragon agents and releases, without requiring users to build the full eBPF project.

How it is used

The official tetra CLI installation docs provide binary downloads for Linux, macOS, and Windows, plus Homebrew installation. They also show tetra connecting to a TLS or mTLS-protected Tetragon gRPC API and running getevents.

In practice, tetra is used by operators who need to inspect Tetragon events, connect to agents, and troubleshoot runtime-security telemetry from a workstation or automation environment.

Why package nerds care

tetra is significant in package catalogs because it packages the user-facing control plane for an eBPF runtime-security system. It sits at the intersection of local CLI ergonomics, Kubernetes operations, and kernel-level observability.

The package is especially relevant on macOS and Linux admin machines: the heavy lifting happens in Linux or Kubernetes, while the packaged CLI gives maintainers a portable way to query and manage it.
