Installation

1. Make a new folder in /etc/ to hold all the files required for this module in one place:

   ## Linux
   mkdir -p /etc/rapdev-datadog
   
   ## Windows
   mkdir 'C:\Program Files\rapdev-datadog\'
   

2. Download the most recent version of the secret backend module by hitting the latest release endpoint from the rapdev-io repo by running one of the commands below:

   ## Linux (amd64)
   curl -L https://github.com/rapdev-io/datadog-secret-backend/releases/latest/download/datadog-secret-backend-linux-amd64.tar.gz \ 
   -o /tmp/datadog-secret-backend-linux-amd64.tar.gz
   
   ## Linux (386)
   curl -L https://github.com/rapdev-io/datadog-secret-backend/releases/latest/download/datadog-secret-backend-linux-386.tar.gz \ 
   -o /tmp/datadog-secret-backend-linux-386.tar.gz
   
   ## Windows (amd64)
   Invoke-WebRequest https://github.com/rapdev-io/datadog-secret-backend/releases/latest/download/datadog-secret-backend-windows-amd64.zip -OutFile 'C:\Program Files\rapdev-datadog\datadog-secret-backend-windows-amd64.zip'
   
   ## Windows (386)
   Invoke-WebRequest https://github.com/rapdev-io/datadog-secret-backend/releases/latest/download/datadog-secret-backend-windows-386.zip -OutFile 'C:\Program Files\rapdev-datadog\datadog-secret-backend-windows-386.zip'
   

3. Once you have the file from the github repo, you'll need to unzip it to get the executable:

   ## Linux (amd64, change end of filename to "386" if needed)
   tar -xvzf /tmp/datadog-secret-backend-linux-amd64.tar.gz \
   -C /etc/rapdev-datadog
   
   ## Windows (amd64, change end of filename to "386" if needed)
   Expand-Archive -LiteralPath 'C:\Program Files\rapdev-datadog\datadog-secret-backend-windows-amd64.zip' -DestinationPath 'C:\Program Files\rapdev-datadog\'
   

4. (Optional) Remove the old tar'd file:

   ## Linux
   rm /tmp/datadog-secret-backend-linux-amd64.tar.gz
   
   ## Windows
   Remove-Item 'C:\Program Files\rapdev-datadog\datadog-secret-backend-windows-amd64.zip'
   

5. Update the executable to have the required permissions. Datadog agent expects the executable to only be used by the dd-agent user for Linux and ddagentuser for Windows.

   ## Linux
   chown dd-agent:root /etc/rapdev-datadog/datadog-secret-backend
   chmod 500 /etc/rapdev-datadog/datadog-secret-backend
   
   ## Windows
   1) Right click on the "datadog-secret-backend.exe" and select "Properties".
   2) Click on the Security tab.
   3) Edit the permissions, disable permission inheritance, and then remove all existing permissions.
   4) Add full access to the "ddagentuser" and save your permissions. 
   

6. Provide an executable path to the datadog agent via the main datadog.yaml file using the secret_backend_command variable:

   ## datadog.yaml ##
   
   secret_backend_command: /etc/rapdev-datadog/datadog-secret-backend
   

7. Provide a configuration for the secrets executable. Documentation for each supported provider can be found here.
