I am trying to manually inject istio sidecar into an existing deployment according to the instructions here:
https://istio.io/docs/setup/kubernetes/additional-setup/sidecar-injection
I am getting the following error, however:
$ istioctl kube-inject -f k8s/prod/deployment.yaml
Error: missing configuration map key "values" in "istio-sidecar-injector"
This error occurs to me even why I try different kinds with different yaml files. Is this a bug or am I doing something wrong? How can I add "values" to the configuration map?
Check the version of your istioctl binary (istioctl version) versus istio installed on your cluster: if they differ, you may get such error message (or similar).

I'm getting this error when trying to run Logstash pipeline with a configuration that is using google_pubsub on a docker container running in my production env:
2021-09-16 19:13:25 FATAL runner:135 - The given configuration is invalid. Reason: Unable to configure plugins: (PluginLoadingError) Couldn't find any input plugin named 'google_pubsub'. Are you sure this is correct? Trying to load the google_pubsub input plugin resulted in this error: Problems loading the requested plugin named google_pubsub of type input. Error: RuntimeError
you might need to reinstall the gem which depends on the missing jar or in case there is Jars.lock then resolve the jars with `lock_jars` command
no such file to load -- com/google/cloud/google-cloud-pubsub/1.37.1/google-cloud-pubsub-1.37.1 (LoadError)
2021-09-16 19:13:25 ERROR Logstash:96 - java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit
This seems to randomly happen when re-installing the plugin. I thought it's a proxy issue but I have the google domain enabled in the whitelist. Might be the wrong one / missing something. Still, doesn't explain the random failures.
Also, when I run the pipeline in my machine I get GCP events, but when I do it on a VM - no Pubsub messages are being pulled. Could it be a firewall rule blocking them?
The error message suggests there is a problem in loading the ‘google_pubsub’ input plugin. This error generally occurs when the input Pub/Sub plugin is not installed properly. Kindly ensure that you are installing the Logstash Plugin for Pub/Sub correctly.
For example, installing Logstash Plugin for Pub/Sub in a VM :
sudo -u root sudo -u logstash bin/logstash-plugin install logstash-input-google_pubsub

I am getting below error while trying to inject istio sidecar container manually to pod.
Kubernetes version v1.21.0
Istio version : 1.8.0
Installation commands:-
kubectl create namespace istio-system
helm install --namespace istio-system istio-base istio/charts/base
helm install --namespace istio-system istiod istio/charts/istio-control/istio-discovery --set global.jwtPolicy=first-party-jwt
In kubectl get events, I can see below error:
Error creating: admission webhook "sidecar-injector.istio.io" denied the request: template: inject:443: function "appendMultusNetwork" not defined
In kube api server logs, below errors are observed:
W0505 02:05:30.750732 1 dispatcher.go:142] rejected by webhook "validation.istio.io": &errors.StatusError{ErrStatus:v1.Status{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, ListMeta:v1.ListMeta{SelfLink:"", ResourceVersion:"", Continue:"", RemainingItemCount:(*int64)(nil)}, Status:"Failure", Message:"admission webhook \"validation.istio.io\" denied the request: configuration is invalid: gateway must have at least one server", Reason:"", Details:(*v1.StatusDetails)(nil), Code:400}}
Please let me know if any clue on how to resolve this error.
I went over step-by-step installation with official documentation, and could not reproduce your problem.
Here are a few things worth checking:
Did you executed all the commands correctly?
Maybe you run a different version of Istio? You can check by issuing istioctl version command
Maybe you changed something in config files? If you did, what exactly?
Try the latest version of Istio (1.9)
Hi I am trying to deploy a node application from cloud 9 to ELB but I keep getting the below error.
Starting environment deployment via CodeCommit
--- Waiting for Application Versions to be pre-processed --- ERROR: Pre-processing of application version app-491a-200623_151654 has
failed. ERROR: Some application versions failed to process. Unable to
continue deployment.
I have attached an image of the IAM roles that I have. Any solutions?
Go to your console and open up your elastic beanstalk console. Go to both applications and environments and delete them. Then in your terminal hit
eb init #Follow instructions
eb create --single ##Follow instructions.
It would fix the error, which is due to some application states which are failed. If you want to check those do
aws elasticbeanstalk describe-application-versions
I was searching for this answer as a result of watching a YouTube tutorial for how to pass the AWS Certified Developer Associate exam. If anyone else gets this error as a result of that tutorial, delete the 002_node_command.config file created in the tutorial and commit that change, as that is causing the error to occur.
A failure within the pre-processing phase, may be caused by an invalid manifest, configuration or .ebextensions file.
If you deploy an (invalid) application version using eb deploy and you enable the preprocess option, The details of the error will not be revealed.
You can remove the --process flag and enable the verbose option to improve error output.
in my case I deploy using this command:
eb deploy -l "XXX" -p
And can return a failure when I mess around with .ebextensions:
ERROR: Pre-processing of application version xxx has failed.
ERROR: Some application versions failed to process. Unable to continue deployment.
With that result I can't figure up what is wrong,
but deploying without -p (or --process)and adding -v (verbose) flag:
eb deploy -l "$deployname" -v
It returns something more useful:
Uploading: [##################################################] 100% Done...
INFO: Creating AppVersion xxx
ERROR: InvalidParameterValueError - The configuration file .ebextensions/16-my_custom_config_file.config in application version xxx contains invalid YAML or JSON.
YAML exception: Invalid Yaml: while scanning a simple key
in 'reader', line 6, column 1:
(... details of the error ...)
, JSON exception: Invalid JSON: Unexpected character (#) at position 0.. Update the configuration file.
Now I can fix the problem.
I am running Knative on a GKE cluster. The sample images provided on the Knative website work but when I switch to some other images, it stops working. Only 2 containers work out of 3 and route's ready state remains 'unknown' and Reason shows as 'RevisionMissing'.
I tried with multiple images, k8s.gcr.io/hpa-example is one of them.
Edit: The cluster has a two-node of configuration of type n1-standard-4 (4 vCPUs, 15 GB memory). I created this cluster using the GCP console with the latest version of kubernetes, and checking the Enable Istio checkbox. I used following commands to install the Knative:
kubectl apply --selector knative.dev/crd-install=true \
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml \
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml \
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml
kubectl apply \
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml \
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml \
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml
Thanks
Ok, I found the problem. I tried posting custom images. All worked until I change the port (inside image) to 80. This image not only work as Knative service, but also, It did not work on Cloud run service as well.
Bottom line is, either pull port number from environment variable, or hard code it to any other port than 80.
Thanks for the precisions.
When you installed Knative you should see this kind of errors

You didn't have installed Istio. Do it, relaunch the knative installation (with and without CRD) to solve previous errors and enjoy!!!
I am doing chaos testing on all istio core components, pilot, mixer, citadel, and default objects/resources. It am manually deleting the components and document the behavior, which will help when it actually breaks in production.
I have deleted ingress-gateway service. It also deleted egress pods, which i didn't expect.
Since I am going to delete all the default objects one by one, Is there a better or more cleaner way to recreate core objects? For example, how would I recreate ingress and egress services?
In my opinion the best way to re-create lost/deleted components of Istio, is to do it by helm (package manager for Kubernetes).
helm upgrade <your-release-name> <repo-name>/<chart-name> --reuse-values --force
You can also keep track of changes of your istio installation (aka Istio release), and simply restore to its last working version using following commands:
helm history <release_name>
helm rollback --force [RELEASE] [REVISION]
Eventually you can always reach out back to Istio installation directory, and re-apply piece of manifest corresponding to deleted object, for example for istio v1.1.1, the istio-ingressgateway Service object is declared inside 'istio-1.1.1/install/kubernetes/istio-demo.yaml'. Additionally these manifest files can be generated by helm template command directly from source code repository.
