In this paper, we will briefly explain the expansion and upgrade of common operation and maintenance operations of kubernetes.1.Node of expansionNode expansion simply means adding new node nodes. Install Kubelet,kube-proxy and Docker on the node and modify the parameters to point to the master address. Based on the Kuberlet automatic registration mechanism, the new node will automatically be added to the ex

Preface:(Application scenario Requirement analysis)Since the installation of the system is not properly planned storage, or as the business expansion to the storage space requirements of the geometric growth, the original planned system storage is insufficient service current business needs, while the current system app is running more perfect, admin does not want to re-plan the new architecture OS, so extend disk Capacity is imminent, so how does you

Python numpy array expansion efficiency The ndarray of the Numpy library allows you to conveniently process multiple dimensions of data. But its biggest drawback is that it cannot be dynamically expanded -- "The NumPy array does not have this function of dynamically changing the size, numpy. the append () function will re-allocate the entire array each time and copy the original array to the new array." (Reference from http://blog.chinaunix.net/uid-2

My Linux version is ubuntu12.04 32bit. Today, when downloading the Android source code, I found that the disk space that I initially allocated to this virtual machine was not enough (only 20G). So you need to expand the disk. on the internet roughly searched, there are two main solutions: one, another disk, two, to the original disk expansion. I chose the second option.1. Shut down the virtual machine. Go to the Settings screen where you want to expan

When the underlying implementation involves scaling up, the container or reassigning a larger contiguous memory (if the discrete allocation does not need to be redistributed, the discrete allocation is the dynamic allocation of memory when inserting new elements), to copy the container's original data all to the new memory, which undoubtedly makes the efficiency greatly reduced.The factor of the load factor is less than or equal to 1, meaning that when the number of elements exceeds the factor o

Introduction to algorithms the 14th chapter of data structure expansionSome engineering applications require only standard data structures, but there are many other applications that require a little innovation and transformation of existing data structures, but only rarely do we need to create new types of data structures, and more often, by storing additional information to expand a standard data structure, This data structure is then written with new operations to support the required applica

U disk expansion, mainly for the current market on the U disk counterfeiters, through technical means, so that a small volume of u disk on the PC display more than its own storage capacity of U disk, and to sell at high prices. For example, a 256 M USB disk can be expanded to 8 G by technical means, then in accordance with the price of 8G sales, if the user to the U disk storage things, more than 256 M of things are lost, while the U disk storage spee

the WiFi connection on the phone when you need to use it. and other solutions to compare, the biggest advantage of wireless hard disk is large capacity, generally can reach TB level, can be stored in a very large number of files, but the disadvantage is that the size of wireless hard disk products is relatively large, carry up or some inconvenient. Dedicated capacity expansion devices are a little expensive In addition to the wireless hard dri

Basic idea: 1: Virtual machine increases disk capacity 2: Add additional disk capacity to the VMware partition 1. Use the df-h command to view the VMware disk information, as shown in the figure (when the capacity of the virtual machine is 20G) 2. First enlarge the VMware hard disk capacity, Operation diagram: Change 20 to 30 3. Then Linux expansion @1: Enter FDISK/DEV/SDA (note space), carriage return appears command (M for help) @2: Check the nu

This time, let's see how to install the chrome plug-in (or 360chrome plug-in) [Reprinted with the source: blog.csdn.net/rovast] 1. Why install the plug-in? After tossing Ubuntu Kylin 14.04, we found that Google was blocked by the Chinese mainland, that is, it was unavailable to in

ByYunshu The previous blogs have been written too long. Today, I want to talk about the problem of permission expansion. This problem also exists in the WEB system, but I only pay attention to network issues here.Most companies use Active Directory to manage the company's PC and employee information. network devices use the user name and group information in the DC for authentication and authorization. For example, NetScreen UAC, Array VPN, Cisco VPN,

First, it was originally in the xaml. the CodeBehind part of cs is easy to control the interface logic. After the logic is m

Linux entry basics: Linux expansion permissions default permissions each terminal has an umask attribute to determine the default permissions for new files and folders umask are represented by digital permissions, for example, the default permission for the 022 directory is: the default permission for the 777-umask file is: 666-umask. For common users, the default umask is 002, and for root users, the default umask is 022, that is, for common users: t
