blue-green/README.md

+# Blue Green
+
+The blue green strategy is not supported by built-in Kubernetes Deployment but available via third-party Kubernetes controller.
+This example demonstrates how to implement blue-green deployment via [Argo Rollouts](https://github.com/argoproj/argo-rollouts):
+
+1. Install Argo Rollouts controller: https://github.com/argoproj/argo-rollouts#installation
+2. Create a sample application and sync it.
+
+```
+argocd app create --name blue-green --repo https://github.com/argoproj/argocd-example-apps --dest-server https://kubernetes.default.svc --dest-namespace default --path blue-green && argocd app sync blue-green
+```
+
+Once the application is synced you can access it using `blue-green-helm-guestbook` service.
+
+3. Change image version parameter to trigger blue-green deployment process:
+
+```
+argocd app set blue-green -p image.tag=0.2 && argocd app sync blue-green
+```
+
+Now application runs `ks-guestbook-demo:0.1` and `ks-guestbook-demo:0.2` images simultaneously.
+The `ks-guestbook-demo:0.2` is still considered `blue` available only via preview service `blue-green-helm-guestbook-preview`.
+
+4. Promote `ks-guestbook-demo:0.2` to `green` by patching `Rollout` resource:
+
+```
+argocd app patch-resource blue-green --kind Rollout --resource-name blue-green-helm-guestbook --patch '{ "status": { "verifyingPreview": false } }' --patch-type 'application/merge-patch+json'
+```
+
+This promotes `ks-guestbook-demo:0.2` to `green` status and `Rollout` deletes old replica which runs `ks-guestbook-demo:0.1`.

helm-dependency/README.md

+# Helm Dependencies
+
+This example application demonstrates how an OTS (off-the-shelf) helm chart can be retrieved and
+pinned to a specific helm sem version from an upstream helm repository, and customized using a custom
+values.yaml in the private git repository.
+
+In this example, the wordpress application is pulled from the stable helm repo, and pinned to v5.0.2:
+
+```yaml
+dependencies:
+- name: wordpress
+  version: 5.0.2
+  repository: https://charts.helm.sh/stable
+```
+
+A custom values.yaml is used to customize the parameters of the wordpress helm chart:
+
+```yaml
+wordpress:
+  wordpressPassword: foo
+  mariadb:
+    db:
+      password: bar
+    rootUser:
+      password: baz
+```
+
+### Subchart Note
+
+The wordpress chart referenced in this example contains a subchart for mariadb as specified in the requirements.yaml file of the wordpress chart:
+```yaml
+- name: mariadb
+  version: 5.x.x
+  repository: https://charts.helm.sh/stable
+  condition: mariadb.enabled
+  tags:
+    - wordpress-database
+```
+
+In order to disable this chart, you must set the value to false for both `mariadb.enabled` and `wordpress.mariadb.enabled`. The first is used by the mariadb subchart condition field, the second is used by the wordpress chart deployment template. An example demonstration is available in the values-nomaria.yaml file:
+```yaml
+mariadb:
+  enabled: false
+
+wordpress:
+  wordpressPassword: foo
+  mariadb:
+    enabled: false
+  externalDatabase:
+    host: localhost
+    user: bn_wordpress

plugins/kasane/README.md

+# Kasane
+
+[Kasane](https://github.com/google/kasane) is a layering tool for Kubernetes which utilises Jsonnet for deep object modification and patching.
+
+Use following steps to try the application:
+
+* Follow instructions from [custom_tools.md](https://github.com/argoproj/argo-cd/blob/master/docs/operator-manual/custom_tools.md) to make sure `kasane` binary is available in `argocd-repo-server` pod.
+* Register `kasane` plugin `argocd-cm` ConfigMap:
+
+```yaml
+apiVersion: v1
+data:
+  configManagementPlugins: |
+    - name: kasane
+      init:
+        command: [kasane, update]
+      generate:
+        command: [kasane, show]
+```
+* Create application using `kasane` as a config management plugin name.
+
+```
+argocd app create kasane \
+    --config-management-plugin kasane \
+    --repo https://github.com/argoproj/argocd-example-apps \
+    --path plugins/kasane \

+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.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+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. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.

+# Helm + Kustomize
+
+Sometimes Helm chart don't have all required parameters and additional customization is required. This example application demonstrates how to combine Helm and Kustomize and use it
+as a config management plugin in Argo CD.
+
+Use following steps to try the application:
+
+* configure `kustomized-helm` tool in `argocd-cm` ConfigMap:
+
+```yaml
+  configManagementPlugins: |
+    - name: kustomized-helm
+      init:
+        command: ["/bin/sh", "-c"]
+        args: ["helm dependency build"]
+      generate:
+        command: [sh, -c]
+        args: ["helm template --release-name release-name . > all.yaml && kustomize build"]
+```
+
+* create application using `kustomized-helm` as a config management plugin name:
+
+
+```
+argocd app create kustomized-helm \
+    --config-management-plugin kustomized-helm \
+    --repo https://github.com/argoproj/argocd-example-apps \
+    --path plugins/kustomized-helm \
+    --dest-server https://kubernetes.default.svc \
+    --dest-namespace default
