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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.

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:

CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
GOOS=$(go env GOOS)
GOARCH=$(go env GOARCH)
curl -L --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}
sha256sum --check cilium-${GOOS}-${GOARCH}.tar.gz.sha256sum
sudo tar -C /usr/local/bin -xzvf cilium-${GOOS}-${GOARCH}.tar.gz
rm cilium-${GOOS}-${GOARCH}.tar.gz{,.sha256sum}

See https://github.com/cilium/cilium-cli/releases for supported GOOS/GOARCH binary releases.
