- If so, calls `istio-iptables` with params to setup pod netns
        - If ambient, sets up the ambient logic.

- `istio-iptables`
    - sets up iptables to redirect a list of ports to the port envoy will listen
    - shared code with istio-init container
    - it will generate an iptables-save config, based on annotations/labels and other settings, and apply it.

### CmdAdd Sidecar Workflow

To use Remote debugging with IntelliJ, replace above step 2 with following:

1. From `./operator/cmd/operator` path run
`
dlv debug --headless --listen=:2345 --api-version=2 -- server
`.

1. In IntelliJ, create a new Go Remote debug configuration with default settings.

  // a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the webhook.
  //
  // - Equivalent: match a request if modifies a resource listed in rules, even via another API group or version.
  // For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1,

  // completedIndexes holds the completed indexes when .spec.completionMode =
  // "Indexed" in a text format. The indexes are represented as decimal integers
  // separated by commas. The numbers are listed in increasing order. Three or
  // more consecutive numbers are compressed and represented by the first and
  // last element of the series, separated by a hyphen.
