load-balancing

问题 I'm currently using Kubernetes on GKE to serve the various parts of my product on different subdomains with the Ingress resource. For example: api.mydomain.com , console.mydomain.com , etc. ingress.yml (current) : apiVersion: extensions/v1beta1 kind: Ingress metadata: name: ingress spec: rules: - host: api.mydomain.com http: paths: - backend: serviceName: api-service servicePort: 80 - host: console.mydomain.com http: paths: - backend: serviceName: console-service servicePort: 80 That works

问题 These are two phrases I hear about very often, mainly associated with Nginx. Can someone give me a laymans defintion? 回答1: Definitions are often difficult to understand.

问题 With AWS services we have the Web application running from the S3 bucket and accessing the data through the REST API from Load Balancer (which is set of Node.js applications running on EC2 instance). Currently we have specified URL's as following: API Load Balancer: api. somedomain.com Static Web App on S3: somedomain.com But having this setup brought us a set of problems since requests are CORS with this setup. We could workaround CORS with special headers, but that doesn't work with all

问题 If I deploy a web app (formerly known as an Azure WebSite) to an App Hosting Plan in Azure with a couple of instances (scale = 2) will the load balancer in front of the instances care if any of the instances is unhealthy? I'm troubleshooting an issue that sometimes causes my site to return an http 503 ~50% of the time. My thinking here is that one of two of my instances has failed but the load balancer hasn't noticed. If the load balancer does care , what does it look for? I can't find anyway

问题 I not sure if this is possible (it wasn't last year according to the internet), but i'm hoping its available now. Is there any way of using google load balancer to force https connection only, ie. get the load balancer to redirect http requests?

As far as I know, forcing HTTPS is not a managed feature of Google Cloud Load Balancer. It will not redirect HTTP to

问题 If I curl a POST request with file upload to my google compute load balancer (LB) I get a 502 error. If I do the same curl to the worker node behind the LB, it works . If I use a library like PHP Guzzle, it works either way. If I do a basic GET request on the LB, I get the correct response but the worker log does not acknowledge receiving the request as if the LB cached it. What is going on? FYI, google LB newb. Thanks Edit: I'm using GCE HTTP LB. The Curl command looks like this: curl http:/
