-# Deploy manifest action for Kubernetes
+# Deploy manifests action for Kubernetes
-Use this action to bake and deploy manifests to Kubernetes clusters.
+
-
+This action is used to deploy manifests to Kubernetes clusters. It requires that the cluster context be set earlier in the workflow by using either the [Azure/aks-set-context](https://github.com/Azure/aks-set-context/tree/releases/v1) action or the [Azure/k8s-set-context](https://github.com/Azure/k8s-set-context/tree/releases/v1) action. It also requires Kubectl to be installed (you can use the [Azure/setup-kubectl](https://github.com/Azure/setup-kubectl) action).
-Assumes that the deployment target K8s cluster context was set earlier in the workflow by using either [`Azure/aks-set-context`](https://github.com/Azure/aks-set-context/tree/releases/v1) or [`Azure/k8s-set-context`](https://github.com/Azure/k8s-set-context/tree/releases/v1)
+
-
+If you are looking to automate your workflows to deploy to [Azure Web Apps](https://azure.microsoft.com/en-us/services/app-service/web/) and [Azure Web App for Containers](https://azure.microsoft.com/en-us/services/app-service/containers/), consider using [`Azure/webapps-deploy`](https://github.com/Azure/webapps-deploy) action.
-#### Artifact substitution
+
-The deploy action takes as input a list of container images which can be specified along with their tags or digests. The same is substituted into the non-templatized version of manifest files before applying to the cluster to ensure that the right version of the image is pulled by the cluster nodes.
+## Action capabilities
-
+
-#### Manifest stability
+Following are the key capabilities of this action:
-Rollout status is checked for the Kubernetes objects deployed. This is done to incorporate stability checks while computing the task status as success/failure.
+
-
+-  **Artifact substitution**: Takes a list of container images which can be specified along with their tags or digests. They are substituted into the non-templatized version of manifest files before applying to the cluster to ensure that the right version of the image is pulled by the cluster nodes.
-#### Secret handling 
+
- The manifest files specfied as inputs are augmented with appropriate imagePullSecrets before deploying to the cluster.
+-  **Object stability checks**: Rollout status is checked for the Kubernetes objects deployed. This is done to incorporate stability checks while computing the action status as success/failure.
-
+
-
+-  **Secret handling**: The secret names specified as inputs in the action are used to augment the input manifest files with imagePullSecrets values before deploying to the cluster. Also, checkout the [Azure/k8s-create-secret](https://github.com/Azure/k8s-create-secret) action for creation of generic or docker-registry secrets in the cluster.
-
+
-```yaml
+-  **Deployment strategy** Supports both canary and blue-green deployment strategies
-- uses: Azure/k8s-deploy@v1
+
-  with:
+   -  **Canary strategy**: Workloads suffixed with '-baseline' and '-canary' are created. There are two methods of traffic splitting supported:
-    namespace: 'myapp' # optional
+      -  **Service Mesh Interface**: Service Mesh Interface abstraction allows for plug-and-play configuration with service mesh providers such as [Linkerd](https://linkerd.io/) and [Istio](https://istio.io/). Meanwhile, this action takes away the hard work of mapping SMI's TrafficSplit objects to the stable, baseline and canary services during the lifecycle of the deployment strategy. Service mesh based canary deployments using this action are more accurate as service mesh providers enable granular percentage traffic split (via service registry and sidecar containers injected into pods alongside application containers).
-    images: 'contoso.azurecr.io/myapp:${{ event.run_id }} '
+      -  **Only Kubernetes (no service mesh)**: In the absence of service mesh, while it may not be possible to achieve exact percentage split at the request level, it is still possible to perform canary deployments by deploying -baseline and -canary workload variants next to the stable variant. The service routes requests to pods of all three workload variants as the selector-label constraints are met (KubernetesManifest will honor these when creating -baseline and -canary variants). This achieves the intended effect of routing only a portion of total requests to the canary.
-    imagepullsecrets: |
+   -  **Blue-Green strategy**: Choosing blue-green strategy with this action leads to creation of workloads suffixed with '-green'. An identified service is one that is supplied as part of the input manifest(s) and targets a workload in the supplied manifest(s). There are three route-methods supported in the action:
-      image-pull-secret1
+
-      image-pull-secret2
+      -  **Service route-method**: Identified services are configured to target the green deployments.
-    manifests: '/manifests/*.*'
+      -  **Ingress route-method**: Along with deployments, new services are created with '-green' suffix (for identified services), and the ingresses are in turn updated to target the new services.
-    kubectl-version: 'latest' # optional
+      -  **SMI route-method**: A new [TrafficSplit](https://github.com/servicemeshinterface/smi-spec/blob/master/apis/traffic-split/v1alpha3/traffic-split.md) object is created for each identified service. The TrafficSplit object is updated to target the new deployments. This works only if SMI is set up in the cluster.
-```
+
-Refer to the action metadata file for details about all the inputs https://github.com/Azure/k8s-deploy/blob/master/action.yml
+      Traffic is routed to the new workloads only after the time provided as `version-switch-buffer` input has passed. The `promote` action creates workloads and services with new configurations but without any suffix. `reject` routes traffic back to the old workloads and deletes the '-green' workloads.

+
+## Traceability Fields Support
+
+-  Environment variable `HELM_CHART_PATHS` is a list of helmchart files expected by k8s-deploy - it will be populated automatically if you are using k8s-bake to generate the manifests.
+-  Use script to build image and add dockerfile-path label to it. The value expected is the link to the dockerfile: https://github.com/${{github.repo}}/blob/${{github.sha}}/Dockerfile. If your dockerfile is in the same repo and branch where the workflow is run, it can be a relative path and it will be converted to a link for traceability.
+-  Run docker login action for each image registry - in case image build and image deploy are two distinct jobs in the same or separate workflows.

+description: A Helm chart for Kubernetes
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+version: 0.1.0
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application.
+appVersion: 1.16.0
