several questions

hello

i have a yaml like this

ingress:
  # ingress.enabled -- Enable ingress resource.
  enabled: true
  albLogs: true
  # ingress.annotations -- Configures annotations for the ingress.
  annotations:
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/healthcheck-path: /v1/healthcheck
  hosts:
    # ingress.hosts[0].host -- Host name for routing traffic.
    - host: whatever
      http:
        paths:
          - path: "/*"
            backend: 
              serviceName: whatever
              servicePort: http
    - host: whatever
      http:
        paths:
          - path: "/*"
            backend: 
              serviceName: whatever
              servicePort: http

and I want to convert it to something like the one below. note the differences after backend:

ingress:
  # ingress.enabled -- Enable ingress resource.
  enabled: true
  albLogs: true
  # ingress.annotations -- Configures annotations for the ingress.
  annotations:
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/healthcheck-path: /v1/healthcheck
  hosts:
    # ingress.hosts[0].host -- Host name for routing traffic.
    - host: whatever
      http:
        paths:
          - path: "/*"
            backend: 
              service:
                name: whatever
                port: 
                  name: http
    - host: whatever
      http:
        paths:
          - path: "/*"
            backend: 
              service:
                name: whatever
                port: 
                  name: http

any hints?
so far i run yq eval '{"service": .ingress.hosts.[].http.paths.[].backend}' file.yaml and it does add the parent service: but i honestly dont know how to merge it?

[mikefarah]

yq e '.ingress.hosts.[].http.paths.[].backend |= {"service": {"name": .serviceName, "port": {"name": .servicePort}}}' file.yaml

• You got the LHS right - you need to update the backend element.
• |= updates the backend node relative to itself (so on the right hand side it's set as the root context).
• On the RHS create the desired 'service' map based on the 'backend' values.

Hope that makes sense!
