Two important points:

  1. webhook is missing. you may use something from updated charts with webhook jlk/terrascan#1

  2. the manifests and the helm chart have to be terrascan compliant

Incase the pod the dies down, the webhook will not allow even the new terrascan pod itself to be created. Thus, creating a deadlock.

Trying to remove myself as a blocker on this. Just pushed some more changes.

@dev-gaur - maybe during your day you can test this out and help with the docs? I haven't made any changes yet around the issue of what happens when the admission controller restarts - probably worth testing by killing the pod and seeing what happens.

If the admission controller webhook is deployed at same time as
terrascan service, there's sometimes a race condition where the
webhook starts before terrascan, and then blocks terrascan from
starting.  So users can read about admission controller in the docs,
and deploy that yaml manually.
