1. Foreword In the last article "Kubernetes Scheduler Module Analysis", the Scheduler scheduling process and the main algorithm are analyzed. From the overall grasp of the scheduler scheduling mechanism, today want to continue to analyze the more detailed content. 2. Summary Today, we mainly analyze the caching mechanism of scheduler, Extender extension mechanism and tainttoleration mechanism. These three aspects, although not so macroscopic, but for

Step 1. Turn on "USB debugging" Pea pods are smart phone PC-side management tools that allow you to download the software you need. If you need to connect pea pods, follow these steps: (Samsung i9158p USB mode Open method diagram) Step 2. Mobile phone and computer connection 1. I now connect our cell phone and computer with a data cable, and then open the "Pea pod" that has been installed in the computer, as shown in the following figure. 2

Services deployed by users on Kubernetes typically run on private networks, and pod and service provide parameters such as Hostport,nodeport to expose these service ports to K8S nodes for user access. There are obvious drawbacks to this approach:1) Easy to occupy excessive host port;2) service ports exposed to multiple hosts increasing the difficulty of firewalls and security configuration3) The default hos

What is the Pea-Pod cloud album? The iOS version is similar to the Android version, and users can easily cloud the photos from their phones via the iOS version of the Pea-Pod Cloud album, when the user's mobile device (Andorid or iOS devices) is connected to the network or computer. Photos from the pea-Pod Cloud backup album can be synchronized to the phone, all

Kubernetes about the service exposure is mainly through the Nodeport way, through the binding minion host of a port, then the pod request forwarding and load balancing, but this way the defect is The service may have many, if each is bound to a node host port, the host needs to open the perimeter of a heap of ports to make services calls, management confusion Cannot apply firewall rules require

Use Google Cloud deployment Manager to install and run Istio's quick start instructions in Google kubernetes Engine(Gke). This quick start is used to create a new Gke cluster, install Istio, and then deploy the BookInfo sample application. It is performed automatically using Deployment Manager and is described in detail in the istio on kubernetes setup Guide . Note: The default installation creates a Gke Al

CocoaPods: an effective solution for installing the same pod in multiple targets, cocoapodspod One of the exciting features of Xcode7 is the ability to perform native UI testing (thanks to Apple), so when I develop a new Xcode 7/Swift 2 project, I put the focus on this. In the unit test process, Quick and Nimble are really comfortable to use, so I also want to use these class libraries in the UI test. Using CocoaPods to install Quick and Nimble is si

2.1"Cloud Backup" feature introduction 2.1.1 uses the "Cloud Backup" feature on the computer side Click the Pea pod in the lower right corner "backup"-"Backup to Cloud" and select what you need to back up. Tip: This feature requires you to log into the Pea pod account. 2.1.2 uses the "Cloud Backup" feature on the handset side Step 1: First connect your phone to the available Wi-Fi network and turn on "

The core issue in Kubernetes architecture is how data is persistance, although it provides persistent volumn, but it is difficult to run and manage products like databases in a kubernetes cluster environment. Kubernetes provides endpoints this mode to map external services into internal services, which solves the problem of cluster external connection,If we are g

1. PrefaceKubernetes designed a special network model that deviates from the native Docker network model. In this design, Kubernetes defines an abstract concept: pods, each pod is a collection of containers, and there is a shared IP, and all containers share the same network namespace. Pods can communicate not only with physical machines, but also between containers across the network. Kubernetes's ip-per-

Configmap Description of KubernetesIn this blog post, let's say a question about customizing the configuration in the pod of kubernetes.We know that in almost all application development, configuration file changes are involved, such as in the Web program, the need to connect to the database, cache, and even queues. And one of our applications starts with writing the first line of code, going through the development environment, the test environment,
