Installation

To build and install, use the install target:

make install

You may set the BINDIR environment variable to install the binary in a specific location instead of /usr/local/bin, e.g.

BINDIR=~/.local/bin make install

Alternatively, to install the latest binary release on Linux or macOS:

OS
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/latest/download/cilium-linux-amd64.tar.gz{,.sha256sum}
sha256sum --check cilium-linux-amd64.tar.gz.sha256sum
sudo tar xzvfC cilium-linux-amd64.tar.gz /usr/local/bin
rm cilium-linux-amd64.tar.gz{,.sha256sum}
