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'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

2) the Che-gateway pod is failing:

Steps Implemented:
AKS cluster with RABAC enabled & Azure CNI
2 subnets in the same vnet with same resource group (Not the RG which starts with MC_)
Provided the contributor & reader access to the AGW after implementing it.
Applied
kubectl apply -f https://raw.githubusercontent.com/Azure/aad-pod-identity/v1.8.8/deploy/infra/deployment-rbac.yaml
Made changes according in the helm-config.yaml and authenticated using identityResourceID.
Suggested us on this exception. Thanks.
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
[ERROR] [error]: Build step io.quarkus.kubernetes.deployment.KubernetesDeployer#deploy threw an exception: io.dekorate.deps.kubernetes.client.KubernetesClientException: Failure executing: POST at: https://IP:8443/apis/apps/v1/namespaces/default/deployments. 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.
Situation:
I've got a CronJob that often fails (this is expected at the moment). Due to the fact that the container performing the job, has a side-car, the dependencies are between the containers are expressed through bash scripts and common mounts of emptyDir in /etc/liveness folder:
spec:
containers:
- args:
- -c
- set -x;
...
./process; # execute the main process
rc=$?;
rm /etc/liveness; # clean-up
exit $rc;
command:
- /bin/bash
Problem:
In the scenarios, where the job fails, I see the following in the logs:
+ rc=255
+ rm /etc/liveness
+ exit 255
With retryPolicy set to never, the failed pod enters the Completed status, which is misleading:
scheduler-1594015200-wl9xc 0/2 Completed 0 24m
According to official doc,
A Job creates one or more Pods and ensures that a specified number of
them successfully terminate.
And containers enter terminated state when
it has successfully completed execution or when it has failed for some
reason.
So if you set retryPolicy to never, this is what will happen.
A Pod's status field is a PodStatus object, which has a phase field.
Ref: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#pod-phase
Status and Phase is not the same. So I learned, that what happens above is that my pods end up in status Completed and phase Failed.
