Kubernetes中的PV和PVC是啥

老子叫甜甜 提交于 2019-12-01 12:50:09
引入了一组叫作Persistent Volume Claim(PVC)和Persistent Volume(PV)的API对象,大大降低了用户声明和使用持久化Volume的门槛。 在Pod的Volumes中,只要声明类型是persistentVolumeClaim,指定PVC的名字,当创建这个PVC对象,k8s就自动为它绑定一个符合条件的Volume,这个Volume,从PV来 PVC和PV的设计,类似“接口”和“实现”的思想,开发者只知道使用“接口”PVC,运维人员负责给“接口”绑定具体的实现PV,说白了PVC就是一种特殊的Volume 一、关于PV创建的流程 大多数情况,持久化Volume的实现,依赖于远程存储服务,如远程文件存储(NFS、GlusterFS)、远程块存储(公有云提供的远程磁盘)等。 K8s需要使用这些存储服务,来为容器准备一个持久化的宿主机目录,以供以后挂载使用,创建这个目录分为两阶段: 1.创建一个远程块存储,相当于创建了一个磁盘,称为Attach 可以理解为创建了一块NFS磁盘,相当于执行 gcloud compute instances attach-disk < 虚拟机名字 > --disk < 远程磁盘名字 > 为了使用这块磁盘,还需要挂载操作 2.将这个磁盘设备挂载到宿主机的挂载点,称为Mount 这远程磁盘挂载到宿主机上,相当于执行 mount

Display total cart shipping volume value in Woocommerce

限于喜欢 提交于 2019-12-01 12:10:13
I use woocommerce for wholesale customers who order containers of furniture - normally 40 foot containers with a volume of 68 cubic meters. Is there a way I can show somewhere on the website - maybe in the header area a box with showing the total m3 of products in their basket? I need to show the client when they reach 68m3 so they know they have filled a container. And is there a way to flash up a message if a client tries to submit an order less than 68m3 indicating to them that they still have room left in their container? Any help is appreciated. You can try something like this: <?php

What's the method to control volume in an MIDI sequencer?

落花浮王杯 提交于 2019-12-01 09:06:18
Can someone show me how to control the volume of an MIDI sequencer without using a sound bank or synthesizer? I want to make the MIDI fade out before continuing to the next MIDI in sequence if(midiplay) { midi = s + savereq; try { //System.out.println("Play MIDI " + midi); if (musicSr != null) { /* This is where I want it to fade out*/ musicSr.stop(); //stop sequencer musicSr.close(); //close sequencer } musicSr = null; musicS = null; File music = new File(midi); if(music.exists()) { musicS = MidiSystem.getSequence(music); } // Create a sequencer for the sequence musicSr = MidiSystem

Adjust OSX System Audio Volume in Python

匆匆过客 提交于 2019-12-01 08:42:11
问题 I would like to adjust the system audio volume in OSX from a python script. This question about implementing keyboard shortcuts tells me how to do it in applescript, but I'd really like to do it from my python script without using os.system, popen, etc. Ideally I'd like to ramp up the volume slowly with some python code like this: set_volume(0) for i in range(50): set_volume(i*2) time.sleep(1) 回答1: Use appscript to control the StandardAdditions scripting addition set volume command: >>> from

How to compare 2 volumes and list modified files?

别来无恙 提交于 2019-12-01 08:32:31
I have 2 hard-disk volumes(one is a backup image of the other), I want to compare the volumes and list all the modified files, so that the user can select the ones he/she wants to roll-back. Currently I'm recursing through the new volume and comparing each file's time-stamps to the old volume's files (if they are int the old volume). Obviously this is a blunder approach. It's time consuming and wrong! Is there an efficient way to do it? EDIT: - I'm using FindFirstFile and likes to recurse the volume, and gather info of each file (not very slow, just a few minutes). - I'm using Volume Shadow

Is it possible to disable volume buttons in iOS apps?

Changing ringer volume during ringing

安稳与你 提交于 2019-12-01 08:12:09
I'd like to change the ringer volume during ringing. Code below sets it during ringing (it is changed in system settings) but it doesn't come to effect with actual ringing (only the next ring call will use new value). Can I force this changes to make them effect Immediately? AudioManager audio = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE); audio.setStreamVolume(AudioManager.STREAM_RING, volume, AudioManager.FLAG_ALLOW_RINGER_MODES | AudioManager.FLAG_PLAY_SOUND); After some research and tests I've found that volume change is possible only in very early stage of incomming

Android Bluetooth Earpiece Volume

我怕爱的太早我们不能终老 提交于 2019-12-01 06:26:13
how can I programmatically set the system volume for voice call when using a bluetooth earpiece? Using this: mAudioManager.setStreamVolume(AudioManager.STREAM_VOICE_CALL, myVolume, 0); when a call (using the Earpice) is in progress it doesn't change anything. I searched a lot before posting, but can't find any hint on how to do it. Thanks in advance. I also got in same problem and found out that, Android is using int 6 for bluetooth volume and not documented. Just use 6 instead of AudioManager.STREAM_VOICE_CALL and try, It should work Yogendra Yaduwanshi This will work. mAudioManager
