You can add a label on the one you want to exclude, and then use queries using labels and selectors to apply operations on the selected set of resources.	###Instruction: I need to know a way to scale down all the deployments on a kubernetes namespace except for one with a specific string inside the name since it has dependencies. This on an AzureCLI task inside of an azure pipeline. Any ideas? Something like: If name contains "randomname" then do not scale up/down the s...

Do each replica of my pod get 1GB storage space (Assuming the PersistentVolume has enough space)? No. Since you use one PersistentVolumeClaim, you will get one PersistentVolume. How would this behave if the pod replicas are on different kubernetes nodes? It will not work, unless you use a volume type that can be us...	###Instruction: I have a PersistenceVolumeClaim defined by apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-pvc spec: storageClassName: "standard" accessModes: - ReadWriteOnce resources: requests: storage: 1Gi And the containers section of the deployment yaml looks like this spec: ...

So there are always a few things that I do when building up a single node for development or testing. My goals are more about creating something which matches the conditions in production, as opposed to reducing overhead. Here's my list: Rename the cluster to something other than "Test Cluster." Set the snitch to Go...	###Instruction: We are running our end-to-end tests using a single Cassandra node running on k8s, this node gets quite a lot reads and writes, note that this node is deleted once tests have finished, so there is no need to consider long term maintenance of data etc. what optimisations would you recommend to configure ...

By default,imagepullpolicy will be Always but there could be chances if there is no change in the deployment file when applying it might not update the deployment. As you are using the same label each time latest. As there different between kubectl apply and kubectl patch command What you can do is add minor label chan...	###Instruction: I am testing automation by applying Gitlab CI/CD to a GKE cluster.

The Azure spot VMs are mostly used when your workload can handle sudden interruptions without damaging the process too much. When it comes to the percentage, the formula looks like this: (total_evictions * time_lost) / total_runtime = eviction rate So for example, let's say that you want to run a VM for 100 hours, and...	###Instruction: I am trying to evaluate whether I should use Spot VMs and the measure for availability is given as a percentage by Azure. https://www.linkedin.com/pulse/viewing-eviction-rates-spot-virtual-machines-azure-portal-dave-callan/ Does anyone know where I can find the average time a VM is available?
