#### Check diffs of manifests

The following command takes two manifests and output the differences in a readable way. It can be used to compare between the manifests generated by operator API and helm directly:

```bash
istioctl manifest diff ./out/helm-template/manifest.yaml ./out/mesh-manifest/manifest.yaml
```

subdirectory as a Cobra command with the following subcommands:

- [manifest](../operator/cmd/mesh/manifest.go): the manifest subcommand is used to generate, install, diff or migrate Istio manifests, it has the following subcommands:
    - [install](../operator/cmd/mesh/install.go): the install subcommand is used to generate an Istio install manifest and apply it to a cluster.

  istioctl profile diff manifests/profiles/default.yaml manifests/profiles/demo.yaml

  # Profile diff by providing a profile name
  istioctl profile diff default demo`,

```console
helm install istio-base -n istio-system manifests/charts/base --set profile=openshift
```

2) `istio-cni` chart installs the CNI plugin. This should be installed after the `base` chart and prior to `istiod` chart. Need to add `--set pilot.cni.enabled=true` to the `istiod` install to enable its usage.

```console
helm install istio-cni -n kube-system manifests/charts/istio-cni --set profile=openshift
```

```bash
$ make operator-proto
```

This will regenerate the Go structs used for schema validation.

## Step 4. Update the generated manifests

Tests of istioctl use the auto-generated manifests to ensure that the istioctl binary has the correct version of the charts.
To regenerate the manifests, run:

```bash
$ make copy-templates update-golden
```
