profile defaults and user overlays, all expressed in Helm values.yaml format. This final values.yaml configuration
is passed to the Helm rendering library and used to render the charts. The rendered manifests are passed to the next
step.
1. Overlays in the user CR are applied to the rendered manifests. No values are ever defined in configuration profile
CRs at this layer, so no merge is performed in this step.

## CLI

or customize the ports to match the old defaults.

#### Other migrations

If you see errors like `rendered manifests contain a resource that already exists` during installation, you may need to forcibly take ownership.

The script below can handle this for you. Replace `RELEASE` and `NAMESPACE` with the name and namespace of the release:

# See the License for the specific language governing permissions and
# limitations under the License.

WD=$(dirname "$0")
WD=$(cd "$WD"; pwd)

set -eux

# This script sets up the plain text rendered deployments for addons
# See samples/addons/README.md for more information

ADDONS="${WD}/../../samples/addons"
DASHBOARDS="${WD}/dashboards"
mkdir -p "${ADDONS}"
TMP=$(mktemp -d)

Use `istioctl` to generate the manifests for the new configuration profile:

```bash
istioctl manifest generate -f manifests/profiles/minimal.yaml
```

After running the command, the Helm charts are rendered using `manifests/profiles/minimal.yaml`.

##### --set syntax

The CLI `--set` option can be used to override settings within the profile.

	match := f
	if match == nil {
