 # linkerd-sp-swagger-sync
+
 Applying Linkerd ServiceProfiles generated from Swagger automatically
+
+### Goal
+
+Linkerd allows to create ServiceProfiles from a Swagger file. This is great when you can generate it locally, or include it somehow in your deployments (Helm, Flux, etc...)
+
+In my case, I want to reconfigure the ServiceProfile of my backends each time I deploy it in Kubernetes, without wondering if my routes have been updated this time or not. Obviously, several version live at the same time in different clusters, I just don't want to track that.
+
+This docker image aims at getting a Swagger documentation online, process it with linkerd commands to generate the ServiceProfile and apply it in cluster.
+
+In my case, I'll run it as a Helm post-upgrade hook.
+
+### Non Goals
+
+This fulfills a very specific use-case and yours may be different. If your contributions are welcomed, please note that this is a side project that I'll maintain on my free time on a best effort basis. 
+
+Of course, feel also free to fork the project: it's under the [MIT license](LICENSE).
+
+### How to run it ?
+
+Work In Progress
