The resulting image should be available remotely, named `ghcr.io/kyverno/kyverno-cli` (by default, if `REGISTRY` environment variable was not set).
|
||||
|
||||
## Deploying a local build
|
||||
|
||||
After [building local images](#building-local-images), it is often useful to deploy those images in a local cluster.
|
||||
|
||||
We use [KinD](https://kind.sigs.k8s.io/) to create local clusters easily.
|
||||
|
||||
### Create a local cluster
|
||||
|
||||
If you already have a local KinD cluster running, you can skip this step.
|
||||
|
||||
To create a local KinD cluster, run:
|
||||
```console
|
||||
make kind-create-cluster
|
||||
```
|
||||
|
||||
You can override the k8s version by setting the `KIND_IMAGE` environment variable (default value is `kindest/node:v1.24.0`).
|
||||
|
||||
You can also override the KinD cluster name by setting the `KIND_NAME` environment variable (default value is `kind`).
|
||||
|
||||
### Build and load local images
|
||||
|
||||
To build local images and load them on a local KinD cluster, run:
|
||||
```console
|
||||
# build kyvernopre image and load it in KinD cluster
|
||||
make kind-load-kyvernopre
|
||||
```
|
||||
or
|
||||
```console
|
||||
# build kyverno image and load it in KinD cluster
|
||||
make kind-load-kyverno
|
||||
```
|
||||
or
|
||||
```console
|
||||
# build kyvernopre and kyverno images and load them in KinD cluster
|
||||
make kind-load-all
|
||||
```
|
||||
|
||||
You can override the KinD cluster name by setting the `KIND_NAME` environment variable (default value is `kind`).
|
||||
|
||||
### Deploy with helm
|
||||
|
||||
To build local images, load them on a local KinD cluster, and deploy helm charts, run:
|
||||
```console
|
||||
# build images, load them in KinD cluster and deploy kyverno helm chart
|
||||
make kind-deploy-kyverno
|
||||
```
|
||||
or
|
||||
```console
|
||||
# deploy kyverno-policies helm chart
|
||||
make kind-deploy-kyverno-policies
|
||||
```
|
||||
or
|
||||
```console
|
||||
# build images, load them in KinD cluster and deploy helm charts
|
||||
make kind-deploy-all
|
||||
```
|
||||
|
||||
This will build local images, load built images in every node of the KinD cluster, and deploy `kyverno` and/or `kyverno-policies` helm charts in the cluster (overriding image repositories and tags).
|
||||
|
||||
> **Note**: This actually uses `ko` to build local images.
|
||||
|
||||
You can override the KinD cluster name by setting the `KIND_NAME` environment variable (default value is `kind`).
|
||||
|
||||
## Building and publishing an image locally
|
||||
|
||||
First, make sure you [install `ko`](https://github.com/google/ko#install)
