Expected Behavior

Validation passes

Actual Behavior

Validation fails

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform validate

Fix

Change this code:

    restart_policy              {
      condition                 = "on-failure"
      delay                     = "10s"
      max_attempts              = 5
      window                    = "10s"
    }

to this:

    restart_policy              = {
      condition                 = "on-failure"
      delay                     = "10s"
      max_attempts              = 5
      window                    = "10s"
    }

Important Factoids

This should be a quick documentation fix. Something along the lines of a note mentioning that Terraform 12 expects restart_policy to have an equal sign before the opening curly brace.
