摘录自k8s中文社区https://www.kubernetes.org.cn/course kubernetes 源自希腊文,意为舵手,k与s之间是8个字母,所以也叫k8s, docker就像一个个的集装箱,容器本身仅提供了托管运行应用的底层逻辑,而容器编排 Orchestration才是真正产生价值所在, 而k8s就是负责运送doker的舵手,负责容器编排 容器编排是指容器应用的自动布局,协同,管理, 主要负责以下任务 Service Discovery Load Balancing Secrets/configuration/storage management Health checks Auto-[scaling/restart/healing] of containers and nodes Zero-downtime deploys 谷歌在容器编排领域已经浸淫十几年,在这期间出现过Docker Swarm, Mesos, 都被比下去了 K8S是容器编排领域的领导者 流程图 功能 基于容器的应用部署、维护和滚动升级 负载均衡和服务发现 跨机器和跨地区的集群调度 自动伸缩 无状态服务和有状态服务 广泛的Volume支持 插件机制保证扩展性 1、pod 一组紧密关联的容器集合,支持多个容器在一个pod中共享网络和文件系统,克通过进程间的通信和共享文件完成任务

How to control volume in android?

天大地大妈咪最大 提交于 2019-11-28 12:35:02
Android has the Hardware button for controlling volume (increase/decrease). I want to same functionality by using buttons in my application with visual volume control and it should be disappeared after some time (in sec). You need to use the AudioManager class. Developer doc is here . Depending on which volume you want to adjust (ringer/media) you may need to change the audiomode via AudioManager . Finally, to make the buttons disappear just use View.GONE on them. I would create a Runnable in the onClickListener and use a postDelayed to make the View disappear. 来源: https://stackoverflow.com

问题 I am working on a game application. But there is a problem on volume control. I want to change media player volume using a seekBar, and not system media volume. Is there any solution for change media player volume via seekBar. Thanks in advance. 回答1: First, get a reference from AudioManager; AudioManager audioMan = (AudioManager) getSystemService(Context.AUDIO_SERVICE); To raise the volume: audioMan.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_RAISE, AudioManager.FLAG

controlling volume in MediaPlayer

I'm playing audio (narration) in an audiobook. The audio files are in .ogg format, between 10 and 15 seconds long each. Edit to add: I'm using Android 2.2, API 8, and I have this in my Manifest: <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> I've got setVolumeControlStream(AudioManager.STREAM_MUSIC); in my onCreate() method. My sounds are being played via code similar to this: mp = MediaPlayer.create(mContext, resource); mp.setOnCompletionListener(this); mp.seekTo(0); mp.setLooping(looping); if(isSoundEnabled()) { mp.setVolume(1, 1); } else { // I still need sounds

Linux LVM逻辑卷管理

使用 Linux 好久了,一定会意识到一个问题,某个分区容量不够用了,想要扩容怎么办?这里就涉及到 LVM 逻辑卷的管理了,可以动态调整 Linux 分区容量。 LVM 概述 全称 Logical Volume Manager ,可以动态调整磁盘容量,提高磁盘管理灵活性。 在安装 CentOS 7 的过程中选择自动分区时,默认就是以 LVM 的方案安装的系统。 但是 /boot 分区必须独立出来,不能基于 LVM 创建。 PV 物理卷 物理卷, Physical Volume ,是 LVM 机制的基本存储设备,通常对应一个普通分区或是整个硬盘。 创建物理卷时,会在分区或磁盘头部创建一个用于记录 LVM 属性的保留区块,并把存储空间分割成默认大小为 4MB 的基本单元(Physical Extend,PE),从而构成物理卷。 普通分区先转换分区类型为 8e ;整块硬盘,可以将所有的空间划分为一个主分区再做调整。 VG 卷组 卷组, Volume Group ,是由一个或多个物理卷组成的一个整体。可以动态添加、移除物理卷,创建时可以指定 PE 大小。 LV 逻辑卷 逻辑卷, Logical Volume ,建立在卷组之上,与物理卷没有直接关系。格式化后,即可挂载使用。 三者关系 通过以上对三者的解释可以看出,建立 LVM 的过程。首先,将普通分区或整个硬盘创建为物理卷;然后

Mounting a Docker volume while being under a Windows host, has been a huge pain for me, and I could not get it to work. Currently I got the following simple Dockerfile: FROM php:5-apache RUN apt-get update When I build an image from it, and start a container docker build -t phisch:dev . docker run phisch:dev the container starts properly. But when I am trying to mount a volume, docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev the following message will be displayed: C:\Users\phisch\dev>docker run -v /c/Users/phisch/dev/htdocs:/var/www phisch:dev no such file or directory docker:

How to control Windows system volume using JScript or VBScript?

强颜欢笑 提交于 2019-11-28 08:40:47
I want to control the volume of my Windows system from a JScript or VBScript script. Any ideas? Also, can I unmute the system volume if it is muted? Helen To mute or unmute the system volume, you can simulate the Mute key press using the WshShell.SendKeys method: var oShell = new ActiveXObject("WScript.Shell"); oShell.SendKeys(Chr(&HAD)); As for changing the volume level from a script, there's a solution that involves some Windows automation, such as launching the System Volume applet and simulating the appropriate keyboard shortcuts in it, but I don't think it's reliable. Therefore I

How to mute the sound of my application?

房东的猫 提交于 2019-11-28 07:52:16
问题 I have an application which has sound. I have a global property to mute the sound. The problem is, there's so many different things which can make sound, I would hate to iterate through different class types and mute/unmute their sound. Instead, I'm looking for a way to mute the sound on a global application level. I don't mean muting the entire system volume either. One scenario: In Windows 7, you can open the Volume Mixer and adjust the volume of individual applications. While I don't

docker 实践四:数据管理

拈花ヽ惹草 提交于 2019-11-28 07:09:18
这篇是关于 docker 的数据管理。 注:环境为 CentOS7,docker 19.03。 一般容器中管理数据主要有两种方式: 数据卷(Data Volumes):容器内数据直接映射到本地主机环境。 数据卷容器(Data Volume Containers):使用特定容器维护数据卷。 主要来介绍如何创建数据卷,并且把本地的目录挂载到容器内,使用数据卷容器在容器和主机之间共享数据,并实现数据的备份和恢复。 数据卷 首先我们先来介绍下什么是数据卷: 数据卷(Data Volume)是一个可供容器使用的特殊目录,是将主机操作系统目录直接映射进容器,类似于Linux的mount命令 。 数据卷可以提供很多很用的特性: 数据卷可以在容器之间共享和重⽤, 容器间传递数据将变得⾼效与⽅便; 对数据卷内数据的修改会⽴马⽣效, ⽆论是容器内操作还是本地操作; 对数据卷的更新不会影响镜像, 解耦开应⽤和数据; 卷会⼀直存在, 直到没有容器使⽤, 可以安全地卸载它。 创建数据卷 创建数据卷使用命令 docker volume create : # docker volume create -d local test test # docker volume list DRIVER VOLUME NAME local
