SpringOne 2018: Gateway

Salaboy - Open Source Knowledge

I love working on Open Source projects around the Kubernetes ecosystem. I also enjoy sharing what I'm learning with others by talking at conferences and going to events. I am currently working for Diagrid in theDapr project.

I am currently also serving as a Steering Committee member in the Knative Project as well as working as the Co-Lead of the Knative Functions project.
I was elected as a Committee member for the Keptn project on Jan 2024.

I published a book titled Platform Engineering on Kubernetes for Manning.

Check the free tutorials and examples from the book in the Platforms on Kubernetes repository.

s1p_gateway's Issues

Discovery Service Filter not working

The gateway works fine when I don't add the discovery filter property, as it picks up all services in my cluster and creates routes to them. However, when I add the property:

spring:
    cloud:
        kubernetes:
            discovery:
                filter: "metadata.labels['s1p']"

and change my service that I want to picked up from the gateway to have a label in the metadata to have s1p: "true", nothing gets picked up and I get this error instead:

org.springframework.expression.spel.SpelEvaluationException: EL1012E: Cannot index into a null value

Any ideas on what I could be doing wrong?

spring-cloud-gateway in GKE

I was planning to install spring-cloud-gateway in gke. Can this be considered a template project ?
Is spring-cloud-gateway configured as an ingress controller ?
Will this automatically connect to other spring boot apps/services defined in gke
How to deploy this gateway in gke ?
Any tools needed ?
