Disk space does not release once the docker rm deleted mirror

itadol5j

I. The root cause of the problem: WSL2 is a "pretty"!

(Coughing)You think you can make room by deleting Docker's mirror? Too naive!

  • WSL2 is virtual.: You play Docker in Windows? It's actually running a Linux virtual machine in the backstage!
  • The virtual hard drive file is a hooligan.: This stuff expands itself (e.g. from 10G to 50G), but it doesn't shrink when it's deleted!
  • The truth.:docker rmi"I don't give a shit, I don't give a shit!

(Sniffling)"It's like you throw trash in your room. The garbage bag will automatically get bigger, but the garbage will be a drum."

II. A solution to the violence: hand-to-hand virtual hard drive!

STEP 0: Find the culprit file

Path:C:\Users\<你的用户名>\AppData\Local\Docker\wsl\data\ext4.vhdx(blood tears warning)

  • Freeze!docker-desktoporUbuntuVhdx file!
  • It is recommended that we copy the path directly.

STEP 1: Kill WSL2 and Docker Process

# 管理员模式打开PowerShell！  wsl --shutdown        # 给WSL2断子绝孙掌  wsl --list -v         # 检查所有WSL状态必须都是"Stopped"  
640-13

(SPEAKING IN LANGUAGE)

  • The taskbar exits the Docker Desktop count! Orders must be used to confirm the process is dead!
  • If you see a release or Running, usewsl -t <发行版名>Swords!

STEP 2: Call on Windows ancestral compression

# 进入DiskPart（手别抖！）  diskpart  # 选中你的虚拟硬盘文件（路径粘贴进来！）  select vdisk file="C:\Users\你的用户名\AppData\Local\Docker\wsl\data\ext4.vhdx"  attach vdisk readonly  # 先礼后兵只读模式  compact vdisk          # 开始压榨空间！  detach vdisk           # 完事提裤子走人  

(Key details)

  • If you're wrong, the file is occupied, go back and check STEP 1!
  • compactThe process may be stuck? Normal! The bigger the files, the slower they go, the more coffee they wait!

STEP 3: Receiving and Inspection Results

  • Go to drive C and see the rest of the space.
  • Reopen Docker Desktop, mirrors and containers!

III. Daily blast guidelines

Regular cleaning of Docker garbage

# 核弹级清理（慎用！）  docker system prune -af  # 删光所有镜像、容器、网络  

♪ To survive ♪

  • This order is not accepted by my mother!

2. Transfer of Docker data to other disks

  • Open Docker Desktop, Settings, Resources, Advanced
  • Modify "Disk image migration" to D/E(principles raging)"Let WSL2 go to another game, and the C drive will laugh at the wind!"

3. Ultimate Austria: Reset WSL2

wsl --unregister docker-desktop-data  # 删库跑路大法  

"It's like formatting! The C drive is thin, but all Docker's data is gone!"

IV. GUIDELINES FOR THROAT SERVATION

Q: No changes in compressed space?A: Three possible scenarios:

  1. Wrong path.data\ext4.vhdxI'm not sure.
  2. WSL2 is clean.wsl --list -vSecond confirmation)
  3. There's no admins.

Q:compact vdiskWrong?A: Check these three orders sequentially!

  1. select vdisk file="正确路径"
  2. attach vdisk readonly
  3. compact vdiskWrong order of direct GG!

Q: Failed to start Docker after changing storage path?A: Give the new path full control!

  • Right-Key Folder Query Properties Query Edit Queue Add "Euper" Quest Full Control

(end assault)

"transmit this one! Have your programmer say goodbye to C-roll anxiety! The next time someone yells at the red C-roll and dumps the article on his face -- "Papa!"

(Xenith added)"Performance of the collection, C-discretion never goes red in three years!"

(author shattering )"In order to test this program, I've reded the C drive eight times and now I see the .vhdx file trying to smash the computer!

Problem? Get in the group.
