 This repo produces one helm chart available via helm repository https://ysoftdevs.github.io/imagepullsecret-injector. There are also 2 docker images:

 The main part is the deployment and the web hook configuration. The flow is as follows
-1. The MutatingWebhookConfiguration we create instructs k8s to pass all requests for creating/updating all ServiceAccounts to our webhook before finishing the request
-1. We check whether the SA has the correctly defined imagepullsecret configuration. if not, we create a patch for the resource
-1. We also check whether we have the secret we are using in the imagepullsecret in the SA's namespace. If not, we create it based on our source secret
-1. We return the patch to k8s, which applies the changes

 Of note is also a fact that the chart runs a lookup to the connected cluster to fetch the CA bundle for the MutatingWebhook. This means `helm template` won't work.

     ```bash
-    kubectl create ns imagepullsecret-injector

     ``` bash
     make build-image
-    helm upgrade -i imagepullsecret-injector \
-        -n imagepullsecret-injector \

     Alternatively, you can use the pre-built, publicly available helm chart and docker images:
     ```bash
-    helm repo add imagepullsecret-injector https://ysoftdevs.github.io/imagepullsecret-injector
+    helm repo add secret-replicator https://ysoftdevs.github.io/secret-replicator
     helm repo update
-    helm upgrade -i imagepullsecret-injector \
-        -n imagepullsecret-injector \
-        magepullsecret-injector/imagepullsecret-injector
+    helm upgrade -i secret-replicator \
+        -n secret-replicator \
+        secret-replicator/secret-replicator
     ```
 
 1. To test whether everything works, you can run
     ```bash
-    kubectl create ns yolo
-    kubectl get sa -n yolo default -ojsonpath='{.imagePullSecrets}'
+    kubectl create ns yolo    
     ```
     The `get` command should display _some_ non-empty result.
