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/
Some OS X users may experience problems using the pre-built binaries in which case Homebrew might be a better option:
brew install cfssl
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: 1.3.4
Revision: dev
Runtime: go1.12.7
The cfssljson command line utility does not provide a way to print its version.
Install kubectl
The kubectl command line utility is used to interact with the Kubernetes API Server.
Download and install latest stable kubectl from the official release binaries:
OS X
curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/darwin/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
Linux
curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl"
chmod +x kubectl
sudo mv kubectl /usr/local/bin/
Verification
Verify kubectl version 1.14.0 or higher is installed:
kubectl version --client
output
Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.1", GitCommit:"4485c6f18cee9a5d3c3b4e523bd27972b1b53892", GitTreeState:"clean", BuildDate:"2019-07-18T09:18:22Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"darwin/amd64"}
