This is the first time I have been trying to install managed Anthos into one of the clusters in GKE. I admit I do not fully understand the full process of installation and troubleshooting I have already done.
It looks like a managed service has failed to install. When I run:...
ANSWERAnswered 2022-Mar-23 at 17:04
I created a new node pool with more CPU and more nodes as I was getting warning about not having enough CPU. Istio service mesh increases the need for CPU.
I migrated my deployment from old node pool to the new one.
istioctl analyze -Aand found a few warnings about
istio-injectionnot being enabled in a few namespaces. I fixed that.
I re run
asmcli installcommand without
./asmcli install --project_id my-app --cluster_name my-cluster --cluster_location europe-west1-b --fleet_id my-app --output_dir anthos-service-mesh --enable_all
All or some of the above did the trick.
I'm trying to access my ETCD database from a K8s controller, but getting rpc error/EOF when trying to open ETCD client.
- ETCD service is deployed in my K8s cluster and included in my Istio service mesh (its DNS record:
- I have a custom K8s controller developed with use of Kubebuilder framework and deployed in the same cluster, different namespace, but configured to be a part of the same Istio service mesh
- I'm trying to connect to ETCD database from the controller, using Go client SDK library for ETCD
Here's my affected Go code:...
ANSWERAnswered 2022-Mar-21 at 08:25
Turned out to be version mismatch - my ETCD db is v3.5.2 and the clientv3 library that I used was v3.5.0. As seen in ETCD changelog (https://github.com/etcd-io/etcd/blob/main/CHANGELOG/CHANGELOG-3.5.md):
I have a spring boot application running in a Nomad cluster with Consul Connect enabled....
ANSWERAnswered 2022-Feb-18 at 06:48
Finally found it. Nomad has an option to expose a particular endpoint via sidecar proxy without mTLS authentication. The use case of this option is specifically for health check or metrics.
expose stanza inside
connect stanza helps to achieve this.
I am trying to understand how we can create circuit breakers for cloud run services,Unlike in GKE we are using istio kind of service mesh how we implement same thing cloud Run ?...
ANSWERAnswered 2022-Jan-30 at 15:53
On GKE you'd set up a circuit breaker to prevent overloading your legacy backend systems from a surge in requests.
To accomplish the same on Cloud Run or Cloud Functions, you can set a maximum number of instances. From that documentation:
Specifying maximum instances in Cloud Run allows you to limit the scaling of your service in response to incoming requests, although this maximum setting can be exceeded for a brief period due to circumstances such as traffic spikes. Use this setting as a way to control your costs or to limit the number of connections to a backing service, such as to a database.
I'm just learning service mesh using istio and I found a strange behavior.
maxRequestsPerConnection of Istio
DestinationRule CRD, I write the below manifest and apply it.
ANSWERAnswered 2021-Nov-03 at 09:35
First things first: HTTP/1.1 does allow multiple request per connection with
Keep-Alive header. This is the default behavior (RFC 2616, Section 8.1).
The documentation is a bit unclear.
maxRequestsPerConnection description states:
Maximum number of requests per connection to a backend. Setting this parameter to 1 disables keep alive. Default 0, meaning “unlimited”, up to 2^29.
Keep-Alive. Setting it to any other value (value > 1) switches
Keep-Alive back on.
Setting this field to proper value (not too high, not too low) is the hard part of configuring Istio, and is dependent on your application needs and traffic.
I'm in the process of vetting a move to service mesh. While
Consul Connect are certainly still in the cards, I'm leaning towards building up from a bit lower level with
I want to build a 'hello world' mesh to test this architecture out. In this hello world mesh, I'd like to be able to issue certificates from
SPIFFE/SPIRE that encode some kind of role. As you can probably tell, I'm new to service meshes. How would I implement roles? Are there any guides out there to help get me started?
ANSWERAnswered 2021-Sep-23 at 16:25
So there isn't any kind of integration with Linkerd and SPIFFE/SPIRE. As of right now there isn't any particular plan for an integration but you can see the existing issue for more details. The next release of Linkerd, 2.11, will include the ability to create server side policy but current versions don't enforce any kind of policy settings.
curl: (56) response reading failed while trying to send email via smtp using curl. checked the isto-proxy logs of sidecar but don't see any
error logs related to this host. Tried the solution mentioned in How to access external SMTP server from within Kubernetes cluster with Istio Service Mesh as well but didn't work.
ANSWERAnswered 2021-Sep-14 at 10:38
Most probably port number is causing the error and if not, try deleting the mesh policies
Also please validate based on below points:
1.If you recently updated istio try downgrading it. 2.Look again in Sidecar logs for any conflicts or try disabling it. 3.When it comes to curl 56 error packet transmission; limit could be the problem.
Can someone help me to understand if service mesh itself is a type of ingress or if there is any difference between service mesh and ingress?...
ANSWERAnswered 2021-Aug-31 at 10:45
An "Ingress" is responsible for Routing Traffic into your Cluster (from the Docs: An API object that manages external access to the services in a cluster, typically HTTP.)
On the other side, a Service-Mesh is a tool that adds proxy-Containers as Sidecars to your Pods and Routs traffic between your Pods through those proxy-Containers.
use-Cases for Service-Meshes are i.E.
- distributed tracing
- secure (SSL) connections between pods
- resilience (service-mesh can reroute traffic from failed requests)
I deployed Istio using the operator and added a custom ingress gateway which is only accessible from a certain source range (our VPN)....
ANSWERAnswered 2021-Aug-19 at 07:33
You can create an ingress class that references the ingress controller that is deployed by default in the istio-system namespace. This configuration with ingress will work, however to my current knowledge, this is only used for backwards compatibility. If you want to use istio ingress controller functionality, you should use istio gateway and virtual service instead:
Using the Istio Gateway, rather than Ingress, is recommended to make use of the full feature set that Istio offers, such as rich traffic management and security features.
If this solution is not optimal for you, you should use e.g. nginx ingress controller and you can still bind it with annotations (deprecated) or using
IngressClass. To my present knowledge it is not possible to bind this ingress class with an additional ingress controller. If you need an explanation, documentation, you should create an issue on github.
Summary: The recommended option is to use the gateway with virtual service. Another possibility is to use nginx alone ingress with different classes and an ingress resource for them.

Apparently, it was a stupid mistake of missing out
serviceAccountName in the deployment template spec.
