# Installing the Client Tools
|
|
|
|
In this lab you will install the command line utilities required to complete this tutorial: [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/darwin/cfssl
|
|
$ curl -o cfssljson https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/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/linux/cfssl \
|
|
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/linux/cfssljson
|
|
```
|
|
|
|
```
|
|
$ chmod +x cfssl cfssljson
|
|
```
|
|
|
|
```
|
|
$ sudo mv cfssl cfssljson /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `cfssl` and `cfssljson` version 1.3.4 or higher is installed:
|
|
|
|
```
|
|
$ cfssl version
|
|
Version: 1.3.4
|
|
Revision: dev
|
|
Runtime: go1.13
|
|
```
|
|
|
|
```
|
|
$ cfssljson --version
|
|
Version: 1.3.4
|
|
Revision: dev
|
|
Runtime: go1.13
|
|
```
|
|
|
|
## 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/v1.15.3/bin/darwin/amd64/kubectl
|
|
```
|
|
|
|
```
|
|
$ chmod +x kubectl
|
|
```
|
|
|
|
```
|
|
$ sudo mv kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Linux
|
|
|
|
```
|
|
$ wget https://storage.googleapis.com/kubernetes-release/release/v1.15.3/bin/linux/amd64/kubectl
|
|
```
|
|
|
|
```
|
|
$ chmod +x kubectl
|
|
```
|
|
|
|
```
|
|
$ sudo mv kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `kubectl` version 1.15.3 or higher is installed:
|
|
|
|
```
|
|
$ kubectl version --client
|
|
Client Version: version.Info{Major:"1", Minor:"17", GitVersion:"v1.17.0", GitCommit:"70132b0f130acc0bed193d9ba59dd186f0e634cf", GitTreeState:"clean", BuildDate:"2019-12-13T11:51:44Z", GoVersion:"go1.13.4", Compiler:"gc", Platform:"darwin/amd64"}
