Installing the Client Tools
In this lab you will install the command line utilities required to complete this tutorial: cfssl, cfssljson, and kubectl.
Install CFSSL
The cfssl and cfssljson command line utilities will be used to provision a PKI Infrastructure and generate TLS certificates.
Download and install cfssl and cfssljson from the cfssl repository:
OS X
curl -o cfssl https://pkg.cfssl.org/R1.2/cfssl_darwin-amd64
curl -o cfssljson https://pkg.cfssl.org/R1.2/cfssljson_darwin-amd64
chmod +x cfssl cfssljson
sudo mv cfssl cfssljson /usr/local/bin/
Linux
wget -q --show-progress --https-only --timestamping \
https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 \
https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
chmod +x cfssl_linux-amd64 cfssljson_linux-amd64
sudo mv cfssl_linux-amd64 /usr/local/bin/cfssl
sudo mv cfssljson_linux-amd64 /usr/local/bin/cfssljson
Verification
Verify cfssl version 1.2.0 or higher is installed:
cfssl version
output
Version: 1.2.0
Revision: dev
Runtime: go1.6
Verify cfssljson version 1.2.0 or higher is installed:
cfssljson -version
Install kubectl
The kubectl command line utility is used to interact with the Kubernetes API Server. Download and install kubectl from the official release binaries:
OS X
curl -o kubectl https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/darwin/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
Linux
wget https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/linux/amd64/kubectl
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
Verification
Verify kubectl version 1.9.0 or higher is installed:
kubectl version --client
output
