migration of ingress do not work

[fragtom]

Promising tool for migration did not work on my ingresses. So, there we have a k8s distribution, where the previously used traefik 1.7~ version should be migrated.

docker run --rm -v ${PWD}:/data containous/traefik-migration-tool ingress --input /data/in --output /data/out 

Produces output, that is identically to input:

apiVersion: v1
items:
- apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    annotations:
      ingress.kubernetes.io/auth-secret: basic-auth-document-db
      ingress.kubernetes.io/auth-type: basic
      ingress.kubernetes.io/custom-request-headers: XYZ-My-Custom-Header:dev
      kubernetes.io/ingress.class: traefik
    creationTimestamp: "2018-02-27T10:03:59Z"
    generation: 9
    name: dev-protected
    namespace: dev
    resourceVersion: "277178439"
    selfLink: /apis/extensions/v1beta1/namespaces/dev/ingresses/dev-protected
    uid: 87d8d657-1ba5-11e8-a9cd-06fa2d724cac
  spec:
    rules:
    - host: svc.test.migrate.traefik.to.v2.com
      http:
        paths:
        - backend:
            serviceName: v2
            servicePort: 80

What could be the trick?

hello,

It's related to items, currently the migration tool don't support that.

If you extract your ingress into files with the following format, the migration will work.

apiVersion: extensions/v1beta1
kind: Ingress

#...

---
apiVersion: extensions/v1beta1
kind: Ingress

#...

When I try to use your file, I have an error:

error while decoding YAML object. Err was: Object 'Kind' is missing in 'apiVersion: v1
...
