> Proposal to add the ability to set a WEB UI PATH for using AWS ALB INGRESS
> --------------------------------------------------------------------------
>
> Key: FLINK-32178
> URL: https://issues.apache.org/jira/browse/FLINK-32178
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator, Runtime / Web Frontend
> Reporter: Tan Kim
> Priority: Major
>
> Currently, the flink kubernetes operator only supports nginx ingress.
> [https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-release-1.5/docs/operations/ingress/]
> Many organizations already using the AWS cloud are using the ALB ingress
> controller and are reluctant to use an additional NGINX ingress controller
> due to the following issues.
> - Using multiple ingress controllers inherently creates the potential for a
> race condition.
> - May not match ALB firewall policy (inbound port range)
> - Each change to the EKS cluster needs to reflect the security groups added
> by ingress
> Using AWS Alb isn't impossible, but there is one problem.
> Those issues are
> If you use domain-based routing, you'll be fine, but it's not going to be
> popular in organizations with a lot of flink apps.
> So you'll want path-based routing, but alb ingress doesn't provide a
> rewrite-target feature, so if you specify a path based on the app name, you
> can't change the path to root(/ ) when routing to the service.
> In fact, this is a problem that would be solved if AWS ALB INGRESS provided
> that functionality on their side, but it hasn't happened in a long time.
> For more information, see:
> [https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/835]
> Therefore, I make the following suggestions.
> Add a setting that allows you to set the PATH of the FLINK WEB UI directly.
> For example, web-ui.path=/flink-app
> If we could specify this, then alb ingress would just route the path to the
> service as is, without using the rewrite-target feature.
