## Example
|
|
|
|
To use your own dev image, such as via [Github Packages](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry), create `kustomization.yml` and alter the overlay to choose `role` or `cluster-role`. This example assumes that a docker image pull secret has been created and named `ghrc-pull`, [see below](#creating-image-pull-secret).
|
|
|
|
```yaml
|
|
apiVersion: kustomize.config.k8s.io/v1beta1
|
|
kind: Kustomization
|
|
resources:
|
|
- https://github.com/itzg/mc-router/kustomize/overlays/role
|
|
# OR
|
|
# - https://github.com/itzg/mc-router/kustomize/overlays/cluster-role
|
|
images:
|
|
- name: itzg/mc-router
|
|
# replace your-user-org with your Github user/org and/or replace ghcr.io with your Docker registry
|
|
newName: ghcr.io/your-user-org/mc-router-dev
|
|
patches:
|
|
- target:
|
|
name: mc-router
|
|
kind: Deployment
|
|
patch: |-
|
|
apiVersion: apps/v1
|
|
kind: Deployment
|
|
metadata:
|
|
name: _
|
|
spec:
|
|
template:
|
|
spec:
|
|
imagePullSecrets:
|
|
- name: ghcr-pull
|
|
containers:
|
|
- name: mc-router
|
|
imagePullPolicy: Always
|
|
```
|
|
|
|
### Creating image pull secret
|
|
|
|
The following is an example of [creating an image pull secret](https://kubernetes.io/docs/reference/kubectl/generated/kubectl_create/kubectl_create_secret_docker-registry/) named `ghrc-pull`. Be sure to replace `your-user-org` and the password will be a [personal access token](https://github.com/settings/tokens) with `read:packages` scope.
|
|
|
|
```shell
|
|
kubectl create secret docker-registry ghcr-pull --docker-server=ghcr.io --docker-username=your-user-org --docker-password=ghp_...
|
|
```
|
|
|
|
### Build and push your image
|
|
|
|
Be sure to replace `your-user-org`:
|
|
|
|
```shell
|
|
docker build -t ghcr.io/your-user-org/mc-router-dev
|
|
docker push ghcr.io/your-user-org/mc-router-dev
|
|
```
|
|
|
|
### Apply the kustomization
|
|
|
|
```shell
|
|
kubectl apply -k .
|
|
```
|
|
|
|
or if you want to preview what will be generated and applied:
|
|
|
|
```shell
|
|
kubectl kustomize
|
|
``` |
