| # Using a Local Docker Registry | ||
|
|
||
| `localregistry.yaml` is a copy of Kubernete's local registry addon, and is included to make it easier to test | ||
| Istio by allowing a developer to push docker images locally rather than to some remote registry. | ||
|
|
||
| ### Run the registry | ||
| To run the local registry in your kubernetes cluster: | ||
|
|
||
| ```shell | ||
| $ kubectl apply -f ./tests/util/localregistry/localregistry.yaml | ||
| ``` | ||
|
|
||
| ### Expose the Registry | ||
|
|
||
| After the registry server is running, expose it locally by executing: | ||
|
|
||
| ```shell | ||
| $ kubectl port-forward --namespace kube-system $POD 5000:5000 | ||
| ``` | ||
|
|
||
| If you're testing locally with minikube, `$POD` can be set with: | ||
|
|
||
| ```shell | ||
| $ POD=$(kubectl get pods --namespace kube-system -l k8s-app=kube-registry \ | ||
| -o template --template '{{range .items}}{{.metadata.name}} {{.status.phase}}{{"\n"}}{{end}}' \ | ||
| | grep Running | head -1 | cut -f1 -d' ') | ||
| ``` | ||
|
|
||
| ### Push Local Images | ||
|
|
||
| Build and push the Istio docker images to the local registry, by running: | ||
|
|
||
| ```shell | ||
| $ make docker push HUB=localhost:5000 TAG=latest | ||
| ``` | ||
|
|
||
| ### Run with Local Images | ||
|
|
||
| #### Running E2E Tests | ||
| If you're running e2e tests, you can set the test flags: | ||
|
|
||
| ```shell | ||
| $ go test <TEST_PATH> -hub=localhost:5000 -tag=latest | ||
| ``` | ||
|
|
||
| #### Hard-coding the Image URL | ||
|
|
||
| You can also modify the image URLs in your deployment yaml files directly: | ||
|
|
||
| ```yaml | ||
| image: localhost:5000/<APP_NAME>:latest | ||
| ``` | ||
