Installing the Client Tools
In this chapter, you will install the command line utilities to client-1, required to complete this tutorial: cfssl, cfssljson, and kubectl.
All procedures in this chapter should be done in client-1.
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:
$ 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
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 kubectl from the official release binaries:
$ wget https://storage.googleapis.com/kubernetes-release/release/v1.12.0/bin/linux/amd64/kubectl
$ chmod +x kubectl
$ sudo mv kubectl /usr/local/bin/
Verification
Verify kubectl version 1.12.0 or higher is installed:
$ kubectl version --client
output
