Step 1: Unpack

Linux (amd64)
Linux (arm64)
macOS (arm64)
Windows (amd64)

tar -zxvf preq-0.1.31-linux-amd64.tar.gz

Example output

preq-0.1.31-linux_amd64/

preq-0.1.31-linux_amd64/preq
preq-0.1.31-linux_amd64/preq.sha256
preq-0.1.31-linux_amd64/preq.sig

tar -zxvf preq-0.1.31-linux-arm64.tar.gz

Example output

preq-0.1.31-linux_arm64/LICENSE
preq-0.1.31-linux_arm64/preq
preq-0.1.31-linux_arm64/preq.sha256
preq-0.1.31-linux_arm64/preq.sig

tar -zxvf preq-0.1.31-darwin-arm64.tar.gz

Example output

preq-0.1.31-darwin_arm64/
preq-0.1.31-darwin_arm64/LICENSE
preq-0.1.31-darwin_arm64/preq
preq-0.1.31-darwin_arm64/preq.sha256
preq-0.1.31-darwin_arm64/preq.sig

note

The macOS preq binary executable is also signed and notarized by Apple.

tar -zxvf preq-0.1.31-windows-amd64.tar.gz

Example output

preq-0.1.31-windows_amd64/
preq-0.1.31-windows_amd64/LICENSE
preq-0.1.31-windows_amd64/preq
preq-0.1.31-windows_amd64/preq.sha256
preq-0.1.31-windows_amd64/preq.sig

Step 2: Install

Install preq to a location of your choosing. We recommend ~/local/bin.

Linux (amd64)
Linux (arm64)
macOS (arm64)
Windows (amd64)

This command is written for bash. If you're using another shell, adjust as needed.

bash
mkdir -p ~/local/bin && cp ./preq-0.1.31-linux_amd64/preq ~/local/bin/preq
echo 'export PATH="$PATH:$HOME/local/bin"' >> ~/.bashrc

This command is written for bash. If you're using another shell, adjust as needed.

bash
mkdir -p ~/local/bin && cp ./preq-0.1.31-linux_arm64/preq ~/local/bin/preq
echo 'export PATH="$PATH:$HOME/local/bin"' >> ~/.bashrc

This command is written for zsh. If you're using another shell, adjust as needed.

zsh
mkdir -p ~/local/bin && cp ./preq-0.1.31-darwin_arm64/preq ~/local/bin/preq
echo 'export PATH="$PATH:$HOME/local/bin"' >> ~/.zshrc

powershell
New-Item -Path "C:\Program Files\Preq" -ItemType Directory -Force
Copy-Item ".\preq-0.1.31-windows_amd64\preq.exe" -Destination "C:\Program Files\Preq\preq.exe"

Add C:\Program Files\Preq to your PATH (how?).

powershell
$preqPath = "C:\Program Files\Preq"; if ($env:Path -notlike "*$preqPath*") { $env:Path += ";$preqPath" }; $machinePath = [Environment]::GetEnvironmentVariable("Path", "Machine"); if ($machinePath -notlike "*$preqPath*") { [Environment]::SetEnvironmentVariable("Path", "$machinePath;$preqPath", "Machine") }

Run preq to verify the correct version is installed.

Linux (amd64)

Optional Step: Verify

All preq binaries and community rule package updates are hashed and signed.

To validate the sha256 hash:

Linux (amd64)
Linux (arm64)
macOS (arm64)
Windows (amd64)

echo "$(cat preq-0.1.31-linux_amd64/preq.sha256)  preq-0.1.31-linux_amd64/preq" | sha256sum -c -

Example output

preq-0.1.31-linux_amd64/preq: OK

echo "$(cat preq-0.1.31-linux_arm64/preq.sha256)  preq-0.1.31-linux_arm64/preq" | sha256sum -c -

Example output

preq-0.1.31-linux_arm64/preq: OK

echo "$(cat preq-0.1.31-darwin_arm64/preq.sha256)  preq-0.1.31-darwin_arm64/preq" | sha256sum -c -

Example output

preq-0.1.31-darwin_arm64/preq: OK

Get-FileHash .\preq-0.1.31-windows_amd64\preq.exe -Algorithm SHA256

Example output

Path

C:\Users\user\Downloads\preq-0.1.31-windows_amd64\preq.exe

Algorithm : SHA256
Hash      : 4B8F2EAB0255686DAD8B5D9EC7329024A5CBFB06
Path      : C:\Users\user\Downloads\preq-0.1.31-windows_amd64\preq.exe

Compare the output to the sha256 hash in preq.sha256.

Kubernetes

Use the kubectl Krew plugin if you are detecting problems in Kubernetes clusters.

Step 1: Install

Krew is the package manager for Kubernetes kubectl plugins. With Krew installed run:

kubectl krew install preq

Example output:

Updated the local copy of plugin index.
Installing plugin: preq
Installed plugin: preq
\
 | Use this plugin:
 | 	kubectl preq
 | Documentation:
 | 	https://github.com/prequel-dev/preq
/
WARNING: You installed plugin "preq" from the krew-index plugin repository.
   These plugins are not audited for security by the Krew maintainers.
   Run them at your own risk.

This will install preq as a kubectl plugin on any of the above supported operating systems and architectures. As with standalone preq, all binaries hashed and signed. And macOS binaries are also notarized and signed by Apple.
