Only internal requests with the host .local will use the Which will activate the rules in the myapp VirtualService that routes to any endpoint of the helloworld service. The ingress requests are using the gateway host (e.g., ) Not be directed to subset v1 but instead will continue to use default round-robin routing. In this situation you will notice that requests to the helloworld service via the ingress gateway will You also have a VirtualService which routes traffic for the helloworld service to a particular subset: apiVersion: /v1beta1 "" # or maybe "*" if you are testing without DNS using the ingress-gateway IP (e.g., ) Let’s assume you are using an ingress Gateway and corresponding VirtualService to access an internal service.įor example, your VirtualService looks something like this: apiVersion: /v1beta1 Route rules have no effect on ingress gateway requests Whenever you apply a DestinationRule, ensure the trafficPolicy TLS mode matches the global server configuration. Thus, the requests conflict with the server proxy because the server proxy expects Otherwise, the mode defaults to DISABLE causing client proxy sidecars to make plain HTTP requests If requests to a service immediately start generating HTTP 503 errors after you applied a DestinationRuleĪnd the errors continue until you remove or revert the DestinationRule, then the DestinationRule is probablyįor example, if you configure mutual TLS in the cluster globally, the DestinationRule must include the following trafficPolicy: trafficPolicy: You should only see this error if you disabled automatic mutual TLS during install. 503 errors after setting destination rule Propagation will take longer and there may be a lag time on the A configuration change will take some time The Istio implementation on Kubernetes utilizes an eventually consistentĪlgorithm to ensure all Envoy sidecars have the correct configuration Refer to the Requirements for Pods and ServicesĪnother potential issue is that the route rules may simply be slow to take effect. Kubernetes services must adhere to certain restrictions in order to take advantage of Your Kubernetes services need to be changed slightly. If route rules are working perfectly for the Bookinfo sample,īut similar version routing rules have no effect on your own application, it may be that With the current Envoy sidecar implementation, up to 100 requests may be required for weighted

Route rules don’t seem to affect traffic flow UF: Failed to connect to upstream, if you’re using Istio authentication, check for a.UO: Upstream overflow with circuit breaking, check your circuit breaker configuration in DestinationRule.NR: No route configured, check your DestinationRule or VirtualService.If you are using a custom log format, make sure to include %RESPONSE_FLAGS%. In the default access log format, Envoy response flags are located after the response code, Run the following command to see the log: $ kubectl logs PODNAME -c istio-proxy -n NAMESPACE By default, access logs are output to the standard output of the container. The best way to understand why requests are being rejected isīy inspecting Envoy’s access logs. Requests may be rejected for various reasons. Configuring SNI routing when not sending SNI.404 errors occur when multiple gateways configured with same TLS certificate.Double TLS (TLS origination for a TLS request).Gateway to virtual service TLS mismatch.Envoy won’t connect to my HTTP/1.0 service.Route rules have no effect on ingress gateway requests.503 errors after setting destination rule.Route rules don’t seem to affect traffic flow.(I don’t know, maybe this is not the end of my adventures). Please check log file for more details: /home/letsencrypt/.acme.sh/acme.sh.log Well and finally I have a 404 error and i can not access to test file in acme directory: zzz.net:Verify error:Invalid response from :

(although how did it work for the first time without all this ?) I had to add a domain from www and add an A record to digital ocean. (http-01): urn:ietf:params:acme:error:dns :: DNS problem: NXDOMAIN looking up A for Skipping. My web server is (include version): nginx version: nginx/1.14.0 (Ubuntu) Further there was such an error: Attempting to renew cert (from /etc/letsencrypt/renewal/produced an unexpected error: Failed authorization procedure. The following certs could not be renewed: (You can set this with the -webroot-path flag). It produced this output: Attempting to renew cert (from /etc/letsencrypt/renewal/produced an unexpected error: Missing command line flag or config entry for this setting: I ran this command: sudo certbot renew -dry-run My hosting provider, if applicable, is: digital ocean

When trying to update, I got various errors. But not a single answer solved my problem.Three months ago, I successfully received a certificate.
