Rules are deleted by 1.1.6 when using redirect actions

[billputer]

I'm using a host-based redirect action as documented here. Specifically, I'm redirecting from one domain to another based on the host-header.

When I upgraded to 1.1.7, I found that all of the rules except for the redirect were deleted from my ALB. After some testing, I found that the rules are created correctly in 1.1.5 and previous versions, but not in 1.1.6+.

Here's the relevant excerpts from my config:

alb.ingress.kubernetes.io/actions.domain-redirect: '{"RedirectConfig":{"Host":"target-host.example.com","Port":"443","Protocol":"HTTPS","StatusCode":"HTTP_301"},"Type":"redirect"}'
alb.ingress.kubernetes.io/conditions.domain-redirect: '[{"Field":"host-header","HostHeaderConfig":{"Values":["test-redirect.example.com"]}}]'

spec:
  rules:
  - http:
      paths:
      - path: /*
        backend:
          serviceName: domain-redirect
          servicePort: use-annotation
      - path: /v1/*
        backend:
          serviceName: backend
          servicePort: 8080
      - path: /ws/*
        backend:
          serviceName: websocket
          servicePort: 8000
      - path: /*
        backend:
          serviceName: frontend
          servicePort: 80

Here's the resulting rules, before and after upgrading to 1.1.6.

Rules in 1.1.5:

Rules in 1.1.6

It's my belief that this is a bug introduced by #1162, which adds behavior to detect unconditional redirects and delete any rules after them.

In the meantime, I've been able to avoid this bug by adding a separate HTTP Ingress rule for that specific hostname, which works for our purposes, but might not be a valid workaround for everyone.

thanks for reporting this, indeed a bug 👍
fixed it in #1286, will cut a release soon.
