-# Deploy manifests action for Kubernetes
-
-This action can be used to deploy manifests to Kubernetes clusters.
-
-This action 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.
-
-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.
-
-## Action capabilities
-
-Following are the key capabilities of this 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.
-
-- **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.
-
-- **Deployment strategy** The action supports canary and blue-green deployment strategies:
-	 - **Canary strategy**: Choosing canary strategy with this action leads to creation of workloads suffixed with '-baseline' and '-canary'. There are two methods of traffic splitting supported in the action:
-	    - **Service Mesh Interface**: Service Mesh Interface abstraction allows for plug-and-play configuration with service mesh providers such as Linkerd and Istio. 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).
-	    - **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.
-	- **Blue-Green strategy**: Choosing blue-green strategy with this action leads to creation of workloads suffixed with '-green'. There are three route-methods supported in the action:
-
-      *Terminolgy: An **identified** service is one that is supplied as part of the input manifest(s) and targets a workload in the supplied manifest(s).
-	    - **Service route-method**: **Identified** services are configured to target the green deployments.
-	    - **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.
-	    - **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. **Note** that this works only if SMI is set up in the cluster.
-	    
-      Traffic is routed to the new workloads only after the time provided as `version-switch-buffer` input has passed. `promote` action creates workloads and services with new configurations but without any suffix. `reject` action routes traffic back to the old workloads and deletes the '-green' workloads.

-## Sample workflows for new 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 2 distinct jobs in the same or separate workflows.

+# Deploy manifests action for Kubernetes
+
+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).
+
+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.
+
+## Action capabilities
+
+Following are the key capabilities of this action:
+
+-  **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.
+
+-  **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.
+
+-  **Deployment strategy** Supports both canary and blue-green deployment strategies
+
+   -  **Canary strategy**: Workloads suffixed with '-baseline' and '-canary' are created. There are two methods of traffic splitting supported:
+      -  **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).
+      -  **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.
+   -  **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:
+
+      -  **Service route-method**: Identified services are configured to target the green deployments.
+      -  **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.
+      -  **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.
+
+      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.

-        // 2) double-up quotes - i.e. " => ""
-        //
-        //    this is different from the libuv quoting rules. libuv replaces " with \", which unfortunately
-        //    doesn't work well with a cmd.exe command line.
-        //
-        //    note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
-        //    for example, the command line:
-        //          foo.exe "myarg:""my val"""
-        //    is parsed by a .NET console app into an arg array:
-        //          [ "myarg:\"my val\"" ]
-        //    which is the same end result when applying libuv quoting rules. although the actual
-        //    command line from libuv quoting rules would look like:
-        //          foo.exe "myarg:\"my val\""
-        //
-        // 3) double-up slashes that preceed a quote,
-        //    e.g.  hello \world    => "hello \world"
-        //          hello\"world    => "hello\\""world"
-        //          hello\\"world   => "hello\\\\""world"
-        //          hello world\    => "hello world\\"
-        //
-        //    technically this is not required for a cmd.exe command line, or the batch argument parser.
-        //    the reasons for including this as a .cmd quoting rule are:
-        //
-        //    a) this is optimized for the scenario where the argument is passed from the .cmd file to an
-        //       external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
-        //
-        //    b) it's what we've been doing previously (by deferring to node default behavior) and we
-        //       haven't heard any complaints about that aspect.
-        //
-        // note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
-        // escaped when used on the command line directly - even though within a .cmd file % can be escaped
-        // by using %%.
-        //
-        // the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
-        // the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
-        //
-        // one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
-        // often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
-        // variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
-        // to an external program.
-        //
-        // an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
