Install tetra CLI

To interact with Tetragon, install the Tetragon client CLI tetra

This guide presents various methods to install tetra in your environment.

Install the latest release

Autodetect your environment

This shell script autodetects the OS and the architecture, downloads the archive of the binary and its SHA 256 digest, compares that the actual digest with the supposed one, installs the binary, and removes the download artifacts.

Note This installation method requires a working Go toolchain, curl(1), and the sha256sum(1) utilities. For Go, see how to install the latest Go release and for the curl and checksum utility, it is usually distributed in common Linux distribution but you can usually find them respectively under the package curl and coreutils.

GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/tetragon/releases/latest/download/tetra-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check tetra-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf tetra-${GOOS}-${GOARCH}.tar.gz
rm tetra-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

Quick install for each environment

This installation method retrieves the adapted archived for your environment, extract it and install it in the /usr/local/bin directory.

Note This installation method requires only curl(1) that should be already installed in your environment, otherwise you can usually find it under the curl package.

Note The architecture amd64 is also referred to as x86_64 or Intel, and arm64 is also referred to as aarch64 or Apple Silicon for Mac computers.
