Sidekiq UI loading wrong assets path in Kubernetes path based routing

You can have a look at the thread I raised with sidekiq team "Sidekiq Route Mount doesn't rewrite URL in Rails API" that helped me understand how sidekiq mount "/sidekiq" works.

I have a simple work around for this problem and found it to be the best way to resolve my path based routing issue. You can do this using nginx.ingress.kubernetes.io/rewrite-target annotations in your Ingress configurations by writing 2 Ingress rules as shown below:

1. Routing the "/" path to the root path of the rails-app-service ( xyz.com/* -> rails-app-service/* )

2. Routing the "/sidekiq" path to the sidekiq web mount path of the rails-app-service ( xyz.com/sidekiq/* -> rails-app-service/sidekiq/* )

To know more about Nginx Ingress Controller rewrite target annotation check the official repository for details: https://github.com/kubernetes/ingress-nginx/tree/master/docs/examples/rewrite#rewrite-target

This is my final code snippet with the solution:

apiVersion: extensions/v1beta1kind: Ingressmetadata:  name: "rails-app-ingress"  annotations:    kubernetes.io/ingress.class: nginx    nginx.ingress.kubernetes.io/ssl-redirect: "false"    nginx.ingress.kubernetes.io/rewrite-target: /spec:  rules:  - host: xyz.com    http:      paths:      - path: /        backend:          serviceName: "rails-app-service"          servicePort: 80---apiVersion: extensions/v1beta1kind: Ingressmetadata:  name: "rails-sidekiq-ingress"  annotations:    kubernetes.io/ingress.class: nginx    nginx.ingress.kubernetes.io/ssl-redirect: "false"    nginx.ingress.kubernetes.io/rewrite-target: /sidekiqspec:  rules:  - host: xyz.com    http:      paths:       - path: /sidekiq        backend:          serviceName: "rails-app-service"          servicePort: 80
