ACS Ansible Notifier

This repo houses example playbooks to facilitate integration use cases between Advanced Cluster Security and an instance of Ansible Automation Controller using Event-Driven Ansible. It's useful in the event that you wish to run an Ansible job in response to an alert from ACS, such as a policy violation.

Deployment Guide

Configure Ansible Automation Controller

Create a Job Template

Ensure that you have a Job Template ready to roll on Automation Controller - we'll be invoking this upon policy violations using the REST API. You'll have access to contextual information in an extra variable called alert, so make sure your Template indicates Prompt on launch for extra variables.

Take a look at the samples directory for some example use cases and corresponding playbooks.

Configure your instance group

If you want your ansible job to perform actions in OpenShift with the k8s module to respond to the policy violation, and you have AAP deployed on OpenShift, you'll probably want to configure your runner Pod template with a service account that has the necessary privileges. In order to to this:

Go to Administration -> Instance Groups in Automation Controller, and edit the default group.
Under Options, select Customize pod specification

In the Custom pod spec, use a custom serviceAccountName and set automountServiceAccountToken to true:

apiVersion: v1
kind: Pod
metadata:
  namespace: ansible-automation-platform
spec:
  serviceAccountName: my-ansible-sa
  automountServiceAccountToken: true
  ...

Then create that ServiceAccount and grant it privileges to do whatever you need it to. For example:

oc -n ansible-automation-platform create serviceaccount my-ansible-sa
oc -n ansible-automation-platform adm policy add-cluster-role-to-user cluster-admin -z my-ansible-sa

Configure Event-Driven Ansible Controller

Next we'll fire up a Rulebook Activation on your Event-Driven Ansible controller to listen for incoming webhook requests.

Be sure to use this repository for the Project (https://github.com/andykrohg/acs-ansible-notifier)
Specify acs-webhook.yml as the Rulebook
Use a default Decision Environment (registry.redhat.io/ansible-automation-platform-24/de-supported-rhel8:latest)
Set a Variable for eda_token. We'll verify that incoming requests provide this token to protect access to the webhook. For example:
```
eda_token: abc123
```

Save the Rulebook Activation and create a route to the generated Kubernetes Service. Then collect the route's hostname:

oc expose $(oc get services -l app=eda -o name)
oc get $(oc get route -o name -l app=eda) --template='{{ .spec.host }}'

Create an Integration spec on ACS

In ACS, go to Platform Configuration -> Integrations
Select Notifier Integrations -> Generic Webhook, and click New Integration
Give your integration a name that matches the Job Template you want to run (e.g. Revoke User Privileges), and provide the route to your Rulebook Activation in the Endpoint
(Optional) Deselect Enable audit logging if all you want to do is respond to alerts
Under Headers, add one that looks like this:
- Key: Authorization
- Value: Bearer abc123 (the token value here should match the one you indicated in the Rulebook Activation)
Under Extra Fields, add one that looks like this:
- Key: template_name
- Value: <the name of your Ansible Job Template>
Then edit the Policy you want to notify on, and add this integration to the list of notifiers
