# Installing the Client Tools
|
|
|
|
In this lab you will install the command line utilities required to complete this tutorial: [cfssl](https://github.com/cloudflare/cfssl), [cfssljson](https://github.com/cloudflare/cfssl), and [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl).
|
|
|
|
|
|
## Install CFSSL
|
|
|
|
The `cfssl` and `cfssljson` command line utilities will be used to provision a [PKI Infrastructure](https://en.wikipedia.org/wiki/Public_key_infrastructure) and generate TLS certificates.
|
|
|
|
Download and install `cfssl` and `cfssljson`:
|
|
|
|
### OS X
|
|
|
|
```
|
|
curl -o cfssl https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/darwin/cfssl
|
|
curl -o cfssljson https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/darwin/cfssljson
|
|
```
|
|
|
|
```
|
|
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](https://brew.sh) might be a better option:
|
|
|
|
```
|
|
brew install cfssl
|
|
```
|
|
|
|
### Linux
|
|
|
|
```
|
|
wget -q --show-progress --https-only --timestamping \
|
|
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssl \
|
|
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssljson
|
|
```
|
|
|
|
```
|
|
chmod +x cfssl cfssljson
|
|
```
|
|
|
|
```
|
|
sudo mv cfssl cfssljson /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `cfssl` and `cfssljson` version 1.4.1 or higher is installed:
|
|
|
|
```
|
|
cfssl version
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
Version: 1.4.1
|
|
Runtime: go1.12.12
|
|
```
|
|
|
|
```
|
|
cfssljson --version
|
|
```
|
|
```
|
|
Version: 1.4.1
|
|
Runtime: go1.12.12
|
|
```
|
|
|
|
## 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/v1.18.6/bin/darwin/amd64/kubectl
|
|
```
|
|
|
|
```
|
|
chmod +x kubectl
|
|
```
|
|
|
|
```
|
|
sudo mv kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Linux
|
|
|
|
```
|
|
wget https://storage.googleapis.com/kubernetes-release/release/v1.18.6/bin/linux/amd64/kubectl
|
|
```
|
|
|
|
```
|
|
chmod +x kubectl
|
|
```
|
|
|
|
```
|
|
sudo mv kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `kubectl` version 1.18.6 or higher is installed:
|
|
|
|
```
|
|
kubectl version --client
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
