I'm trying to install the Eclipse-Che by following this blog : https://che.eclipseprojects.io/2022/07/25/#karatkep-installing-eclipse-che-on-aks.html,
yet following all the steps i'm not able to successfully install the Eclipse che.
1)
After running this command:
kubectl logs -l app.kubernetes.io/component=che-operator -n eclipse-che -f
these are the errors i'm facing:
logs: Waited for 1.034843163s due to client-side throttling, not priority and fairness, request: GET:https://10.1.0.1:443/apis/discovery.k8s.io/v1?timeout=32s
time="2022-09-12T14:08:29Z" level=info msg="Successfully reconciled."
2) the Che-gateway pod is failing:
che-gateway-7d54ccdd59-bblw6 3/4 CrashLoopBackOff 18 (2m51s ago) 70m

Im setting up a gitlab runner in my kubernets cluster.
The runner is properly deployed and running. When I trigger any pipeline, during the prepare stage it fails with an authentication error to pull from my private docker registry:

I already tried by adding in the runner deployment imagePullSecrets (kubernetes.io/dockerconfigjson) and also in the gitlab -> Settings -> CI/CD -> environment variable -> DOCKER_AUTH_CONFIG but no success for any of those.
Where is the correct place to add it? Im using helm chart.
my .gitlab-ci.yaml:
.base-terraform:
image:
name: myprivaterepo.com/terraform:light
In my DOCKER_AUTH_CONFIG I had a domain with different port than the actual one. gilab-ci used this project env variable automatically as it should be.
I am trying to follow this tutorial on deploying Hyperledger Fabric on Kubernetes. But instead of IBM Cloud, I'm doing it with Google Cloud. I encountered this same issue (see my logs below) and tried:
changing docker image to docker:18.09-dind in docker.yaml.
setting FABRIC_CFG_PATH=$PWD/configFiles instead of FABRIC_CFG_PATH=$PWD in create_channel.yaml according to another StackOverflow answer.
However, these workaround did not work for me and I still encounter the error.
How do I fix this to be able to successfully deploy the network?

FABRIC_CFG_PATH setting is wrong.
Currently, your error is a phrase that occurs when there is a problem with the syntax in the configtx.yaml file or when the file path is wrong and cannot be found.
For configtxgen, refer to the configtx.yaml file under FABRIC_CFG_PATH.
In the tutorial you provided, configtx.yaml is not found under configFiles directory and it exists under artifacts directory.
I'll suggest two of the easiest solutions out of many.
move artifacts/configtx.yaml to configFiles/configtx.yaml
mv ./artifacts/configtx.yaml configFiles/configtx.yaml
Or, set FABRIC_CFG_PATH to configFiles
export FABRIC_CFG_PATH=${PWD}/artifacts
I am trying to mount a volume to a Pod so that one deployment can write to it, and another deployment can read from it. I am using MiniKube with Docker on Ubuntu. I am running ./mvnw clean package -Dquarkus.kubernetes.deploy=true.
From the Quarkus documentation, it seems pretty straightforward, but I'm running into trouble.
When I add this line quarkus.kubernetes.mounts.my-volume.path=/volumePath to my application.properties, I get the following error:
[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:1.6.0.Final:build (default) on project getting-started: Failed to build quarkus application: io.quarkus.builder.BuildException: Build failure: Build failed due to errors

Message: Deployment.apps "getting-started" is invalid: spec.template.spec.containers[0].volumeMounts[0].name: Not found: "my-volume". Received status: Status(apiVersion=v1, code=422, details=StatusDetails(causes=[StatusCause(field=spec.template.spec.containers[0].volumeMounts[0].name, message=Not found: "my-volume", reason=FieldValueNotFound, additionalProperties={})], group=apps, kind=Deployment, name=getting-started, retryAfterSeconds=null, uid=null, additionalProperties={}), kind=Status, message=Deployment.apps "getting-started" is invalid: spec.template.spec.containers[0].volumeMounts[0].name: Not found: "my-volume", metadata=ListMeta(_continue=null, remainingItemCount=null, resourceVersion=null, selfLink=null, additionalProperties={}), reason=Invalid, status=Failure, additionalProperties={}).
When I add quarkus.kubernetes.config-map-volumes.my-volume.config-map-name=my-volume (along with the previous statement), the error goes away, but the pod does not start. Running "kubectl describe pods" returns:
Normal Scheduled <unknown> default-scheduler Successfully assigned default/getting-started-859d89fc8-tbg6w to minikube
Warning FailedMount 14s (x6 over 30s) kubelet, minikube MountVolume.SetUp failed for volume "my-volume" : configmap "my-volume" not found
Does it look like the volume is not being set in the YAML file?
So my question is, how can I set the name of the volume in application.properties, so I can have a volume mounted in the Pod?
I recommend you look at your kubernetes.yml and kubernetes.json files under target/kubernetes
For the first error. It looks like my-volume needs to exist in your cluster either as a Persistent Volume.
For the second error quarkus.kubernetes.config-map-volumes.my-volume.config-map-name=my-volume is meant to be used as a ConfigMap so the actual ConfigMap needs to be defined/exist in your cluster.
I'm trying to upgrade my gke cluster from this command:
gcloud container clusters upgrade CLUSTER_NAME --cluster-version=1.15.11-gke.3 \
--node-pool=default-pool --zone=ZONE

ERROR: (gcloud.container.clusters.upgrade) Operation [DATA_SAME_AS_IN_TIMEOUT] is still running
I just discovered gcloud config set builds/timeout 3600 so I hope this doesn't happen again, like in my CI. But if it does, is there a gcloud command that lets me know that the upgrade is still in progress? These two didn't provide that:
gcloud container clusters describe CLUSTER_NAME --zone=ZONE
gcloud container node-pools describe default-pool --cluster=CLUSTER_NAME --zone=ZONE
Note: Doing this upgrade in the console took 2 hours so I'm not surprised the command-line attempt timed out. This is for a CI, so I'm fine looping and sleeping for 4 hours or so before giving up. But what's the command that will let me know when the cluster is being upgraded, and when it either finishes or fails? The UI is showing the cluster is still undergoing the upgrade, so I assume there is some command.
TIA as usual
Bumped into the same issue.
All gcloud commands, including gcloud container operations wait OPERATION_ID(https://cloud.google.com/sdk/gcloud/reference/container/operations/wait), have the same 1-hour timeout.
At this point, there is no other way to wait for the upgrade to complete than to query gcloud container operations list and check the STATUS in a loop.
I have a Kubernetes cluster deployed locally to a node prepped by kubeadm.
I am experimenting with one of the pods. This pod fails to deploy, however I can't locate the cause of it. I have guesses as to what the problem is but I'd like to see something related in the Kubernetes logs
Here's what i have tried:
$kubectl logs nmnode-0-0 -c hadoop -n test
Error from server (NotFound): pods "nmnode-0-0" not found
$ kubectl get event -n test | grep nmnode
(empty results here)
$ journalctl -m |grep nmnode
and I get a bunch of repeated entries like the following. It talks about killing the pod but it gives no reason whatsoever for it

The cluster is still running. Do you know how I can get to the bottom of this?
Try to execute command below:
$ kubectl get pods --all-namespaces
Take a look if your pod was not created in a different namespace.
Most common reason of pod failures:
1. The container was never created because it failed to pull image.
2. The container never existed in the runtime, and the error reason is not in the "special error list", so the containerStatus was never set and kept as "no state".
3. Then the container was treated as "Unkown" and the pod was reported as Pending without any reason.
The containerStatus was always "no state" after each syncPod(), the status manager could never delete the pod even though the Deletiontimestamp was set.
Useful article: pod-failure.
try this command to get some hints
kubectl describe pod nmnode-0-0 -n test
