QUESTION
I am having a problem using Kubernetes Ingress with a ASP.NET core web API.
Lets say I have a web API with three controllers (simplified code to demonstrate three routes /, /ep1, /ep2):

Answered 2021-Jun-14 at 18:57Routing within the app should be handled by the app. So, there should be no need to define dynamic paths. Try this.
QUESTION
I originally posted this question as an issue on the GitHub project for the AWS Load Balancer Controller here: https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/2069.
I'm seeing some odd behavior that I can't trace or explain when trying to get the loadBalacnerDnsName from an ALB created by the controller. I'm using v2.2.0 of the AWS Load Balancer Controller in a CDK project. The ingress that I deploy triggers the provisioning of an ALB, and that ALB can connect to my K8s workloads running in EKS.
Here's my problem: I'm trying to automate the creation of a Route53 A Record that points to the loadBalancerDnsName
of the load balancer, but the loadBalancerDnsName
that I get in my CDK script is not the same as the loadBalancerDnsName
that shows up in the AWS console once my stack has finished deploying. The value in the console is correct and I can get a response from that URL. My CDK script outputs the value of the DnsName as a CfnOutput value, but that URL does not point to anything.
In CDK, I have tried to use KubernetesObjectValue
to get the DNS name from the load balancer. This isn't working (see this related issue: https://github.com/aws/aws-cdk/issues/14933), so I'm trying to lookup the Load Balancer with CDK's .fromLookup
and using a tag that I added through my ingress annotation:
ANSWER
Answered 2021-Jun-13 at 20:23I think that the answer is to use external-dns.
ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way.

...ANSWER
Answered 2021-Jun-12 at 02:54I notice that you're connecting to https://mydomain.dev
, but passing a host header for a different domain. My guess would be that curl
is sending an SNI request for a mydomain.dev
cert; since networking-ns-cert
will acquire wildcard certs for *..my domain.dev
, it's possible that the server doesn't have a cert matching the SNI request, and closes the TCP connection.
Try using the -kvv
options to curl
(instead of -v
) to print more verbose debugging information and bypass some SSL errors. Since you have DNS and certs set up, I'd try:
curl -kvv https://helloworld-go.default.mydomain.dev

QUESTION
I am a little bit confused about my network setup at home.
This is the setup:
VLAN1 - 172.16.20.0/24 VLAN2 - 10.11.12.0/24
I am in the VLAN2 net (which is my WiFi), for the moment I allowed all traffic between both subnets.
My setup uses a KVM host for most of the services, my firewall lies on this machine and is virtualized (opnsense).
So the KVM network interfaces looks like this:

Answered 2021-Jun-11 at 17:32I fixed it by myself. The management interface itself was missing a route to the VLAN2 net. Works now :)

QUESTION
I'm trying to create an internal ingress for inter-cluster communication with gke. The service that I'm trying to expose is headless and points to a kafka-broker on the cluster.
However when I try to load up the ingress, it says it cannot find the service?
...ANSWER
Answered 2021-Jun-11 at 11:12Setting up ingress for internal load balancing requires you to configure a proxy-only subnet on the same VPC used by your GKE cluster. This subnet will be used for the load balancers proxies. You'll also need to create a fw rule to allow traffic as well.
Have a look at the prereqs for ingress and then look here for info on how to setup the proxy-only subnet for your VPC.

i'm working on a new idea for which I've created a setup as follows on Azure Kubernetes:
- 1 cluster
- 1 node pool in said cluster
- 1 deployment which creates 2 pods in the pool
- 1 load balancer service balancing requests between the 2 pods
I'm trying to submit a json request into the loadbalancer from outside the cluster with an AKS IP, to which i encounter 502 Bad Gateway issues.
This is my deployment file

QUESTION
I have a JBOSS server (7.0) running an application that uses ServiceWorkers, which requires an HTTPS connection. I was able to update the standalone.xml and Eclipse launch configuration to bind my JBOSS server to my local IP (I'll worry about port forwarding later). Connecting to http://192.168.0.197:8080/[application] works just fine, except that ServiceWorkers won't start because it isn't an HTTPS connection. If I try https://192.168.0.197:8080/[application], the connection fails with the browser reporting "unable to connect".
I've researched several documentation sources and can't figure out what needs to be updated. Please forgive any terminology errors - my background is with application programming and networking tends to be the bane of my existence.
This is the pertinent standalone.xml configuration:
