# 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/#kubectl).
|
|
|
|
## Install CFSSL
|
|
|
|
The `cfssl` and `cfssljson` command line utilities will be used to provision a [public key infrastructure (PKI)](https://en.wikipedia.org/wiki/Public_key_infrastructure) and generate TLS certificates.
|
|
|
|
Download and install `cfssl` and `cfssljson`:
|
|
|
|
### OS X
|
|
|
|
```
|
|
ARCH='arm64' # replace arm64 with amd64 if needed
|
|
|
|
curl --location --output cfssl --time-cond cfssl \
|
|
"https://github.com/cloudflare/cfssl/releases/download/v1.6.4/cfssl_1.6.4_darwin_${ARCH}"
|
|
|
|
curl --location --output cfssljson --time-cond cfssljson \
|
|
"https://github.com/cloudflare/cfssl/releases/download/v1.6.4/cfssljson_1.6.4_linux_${ARCH}"
|
|
|
|
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://github.com/Homebrew/brew) might be a better option:
|
|
|
|
```
|
|
brew install cfssl
|
|
```
|
|
|
|
### Linux
|
|
|
|
```
|
|
curl --location --output cfssl --time-cond cfssl \
|
|
https://github.com/cloudflare/cfssl/releases/download/v1.6.4/cfssl_1.6.4_linux_amd64
|
|
|
|
curl --location --output cfssljson --time-cond cfssljson \
|
|
https://github.com/cloudflare/cfssl/releases/download/v1.6.4/cfssljson_1.6.4_linux_amd64
|
|
|
|
sudo install --mode 0755 cfssl cfssljson /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `cfssl` and `cfssljson` version 1.6.4 or higher is installed:
|
|
|
|
```
|
|
cfssl version
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
Version: 1.6.4
|
|
Runtime: go1.18
|
|
```
|
|
|
|
```
|
|
cfssljson --version
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
Version: 1.6.4
|
|
Runtime: go1.18
|
|
```
|
|
|
|
## 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 --location --remote-name --time-cond kubectl \
|
|
"https://dl.k8s.io/release/v1.27.4/bin/darwin/${ARCH}/kubectl"
|
|
|
|
chmod +x kubectl
|
|
|
|
sudo mv kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Linux
|
|
|
|
```
|
|
curl --location --remote-name --time-cond kubectl \
|
|
https://dl.k8s.io/release/v1.27.4/bin/linux/amd64/kubectl
|
|
|
|
sudo install --mode 0755 kubectl /usr/local/bin/
|
|
```
|
|
|
|
### Verification
|
|
|
|
Verify `kubectl` version 1.27.4 or higher is installed:
|
|
|
|
```
|
|
kubectl version --client --short
|
|
```
|
|
|
|
> output
|
|
|
|
```
|
|
Client Version: v1.27.4
|
|
Kustomize Version: v5.0.1
|
|
```
