persistent-storage

It seems that Kubernetes supports 3 kinds of access mode for persistent volume: ReadWriteOnce , ReadOnlyMany , ReadWriteMany . I'm really curious about the scheduler strategy for a pod which uses the ReadWriteOnce mode volume. For example, I created an RC which have pod num=2, I guess the two pods will be scheduled into the same host because they use the volume that has ReadWriteOnce mode? I really want to know the source code of this part. DavidO If a pod mounts a volume with ReadWriteOnce access mode, no other pod can mount it. In GCE (Google Compute Engine) the only allowed modes are

I am creating multiple persistent store in my application, but I am using only one persistent store coordinator and managed object model. Now my question is when I call save method on managed object context, which persistent store it will use to save the object. So I want to specify the persistent store to be used to save the object. Same while fetching the objects from database, I want to ensure that my fetch query should be executed on a particular store so that I get objects from that store only. Any help? Fetching should not be an issue. The fetch request can be modified to search

Base question: When I try to use kube-apiserver on my master node, I get command not found error. How I can install/configure kube-apiserver? Any link to example will help. $ kube-apiserver --enable-admission-plugins DefaultStorageClass -bash: kube-apiserver: command not found Details: I am new to Kubernetes and Docker and was trying to create StatefulSet with volumeClaimTemplates. My problem is that the automatic PVs are not created and I get this message in the PVC log: "persistentvolume-controller waiting for a volume to be created". I am not sure if I need to define DefaultStorageClass and

I have an application that will need extremely little persistent storage. Realistically, we're talking about < 30 integers. All the application needs is to know those integers on next startup (and the integers do change as it runs). A database is overkill for this, but I don't particularly want to just use a text file either. Does C# have any mechanism for persisting small values like this between runs? I've noticed you can store things in resource files and some other places - I don't know if you can change those in the runtime though. I'm just learning C# & .NET for a new job, so apologies

I have an array of objects each with a number of properties. Here is some sample data taken by looping through the array of objects: Name = Rent Default Value 750 This Months Estimate = 750 Sum Of This Months Actuals = 0 Risk Factor = 0.0 Monthly Average = 750.0 -------------- Name = Bills Default Value 250 This Months Estimate = 170 Sum Of This Months Actuals = 140 Risk Factor = 0.0 Monthly Average = 190.0 -------------- Name = Food Default Value 240 This Months Estimate = 200 Sum Of This Months Actuals = 95 Risk Factor = 0.0 Monthly Average = 190.0 -------------- Name = Lunches Default Value

When I push my deployments, for some reason, I'm getting the error on my pods: pod has unbound PersistentVolumeClaims Here are my YAML below: This is running locally, not on any cloud solution. apiVersion: extensions/v1beta1 kind: Deployment metadata: annotations: kompose.cmd: kompose convert kompose.version: 1.16.0 () creationTimestamp: null labels: io.kompose.service: ckan name: ckan spec: replicas: 1 strategy: {} template: metadata: creationTimestamp: null labels: io.kompose.service: ckan spec: containers: image: slckan/docker_ckan name: ckan ports: - containerPort: 5000 resources: {}

I am using coreData, with one -to-many realtionship, I have a folder entity and a file entity. A folder can have many files and so on. So, I have two ViewControllers, FolderViewController and FileViewController which contains folders and files respectively.Now I have a modalView , which is accesible from both folder and file viewcontroller. In this VC I have a button to Reset all Data. So when I click this I want all the data should reset. I used this code,this function is written in appdelegate.m and called from my VC. - (void)resetToDefault { NSError * error; // retrieve the store URL NSURL

This question already has an answer here: Persist variables between page loads 4 answers I have created a JavaScript object. var myObj = {}; Now as user plays-around with the application, we assign some values to this object. myObj['Name'] = 'Mr. Gates'; myObj['Age'] = 58; ... ... ... myObj['Role'] = 'CEO'; But whenever the page refresh's, the object looses its values. Is there any way using HTML 5\or any other technique to persist these values across page refresh. Yes, you have two primary choices: Using a cookie. Cookies are easy to set from JavaScript, but a bit of a pain to read. You've
