Dockerwsl taking too much space. I seldom observe much swap usage in linux system.

Dockerwsl taking too much space. Docker flooding syslog with run-docker-runtime logs. 1889] WSL Version WSL 2 WSL 1 Kernel Version 5. I have tried the command: Optimize -VHD -Path Over time, Docker Desktop running on Windows Subsystem for Linux 2 (a. My C:\\ drive is running out of space so I want to force Docker to store the image and containers on my D:\\ drive. So I delete all of /nix. When is try to run sudo My laptop has only 147 GB of space and run Windows 10 as my C Drive. 1. 0. Using du -hs --exclude mnt/ on path ~/. Hot I observed the same issue: wsl2 got bigger and bigger and even when I deleted files inside of wsl2, I couldn't see the free space reflected on my host machine. I tried my best to confirm if I was saving some junk somewhere prompting this behaviour but cannot find it. Have you wondered where all your hard drive space is going? Have you seen that the folder c:\users\<yourname>\AppData\Local\Docker\WSL\Data is growing and never shrinking? Well in that folder sits a virtual hard disk called ext4. I ran docker stop $(docker ps -aq) to kill all running containers (there were 12 - oops) which has improved the issue significantly. I have a folder that contains code + weights of neural networks + annoy indices and takes approximately 16 GB. by removing unused images, vhdx doesn't shrink automatically. vhdx images. If I close Docker Desktop from the Task Tray Icon the RAM will go down to nothing. I am still missing 30GB that I don't know how to get back. (Not really, but let's say that was too much for me). 0 running on Windows/10 home with WSL2. e. To reclaim the disk space, you have to try clean/purge data option from the GUI. It will not take all that space up from your drive, it will increase as it need to. 0. 20: 13066: November 21, 2023 Disk space usage. I Hi, I’ve been using docker compose deployments on different servers. One of them is taking up disk space. These objects are generally not removed unless you explicitly ask Docker to do so. During our work, the size of the WSL file will become larger and larger. Ask Question Asked 9 months ago. Will the disk size be reduced dynamically as I use my C:/ drive or do I have to manually reduce If you are troubled by that /var/lib/docker/overlay2 directory is taking too much space(use du command to check space usage), then the answer below may be suitable for you. /. 11. In this post, we'll look at the different Docker artifacts that can take up space on your system, how to clear them individually, and how to use docker system prune to clear Docker cache. Assuming you have a bigger disk partition on your computer, say /bigdisk, here are the possible solution: Temp dir Docker running on Ubuntu is taking 18G of disk space (on a partition of 20G), causing server crashes. This can cause Docker to use extra disk space. For instance, creating a 1GB file in WSL/Ubuntu will grow the size of the virtual disk image by 1GB. When I then try to delete the container I tried to commit, it cannot be done because my hard drive is full. Not that very nice. Docker Desktop. Docker Desktop for Windows uses WSL to manage all your images and container files and There are many ways to clean up the disk space used by Docker on WSL2. vhd file is still very large (~70 GB) while running du inside WSL reports only about 10 GB. vhdx -Mode Full. Viewed 6k times 0 I started using Docker recently and Docker was taking up too much space even after i prune all the dangling containers and images. It works OK normally, until I run out of disk space Even when the container is shut down and removed, I still have 95GB of data in c:\Users\me\AppData\Local\Temp\docker-index\sha256 . You can see how much space the WSL2 virtual disk is actually taking by searching your drive for ext4 Which is much more than the 1GB limit that I set. Unfortunately, if you reclaim some space, i. I found that there is “undocumented” (i. The hard disc image file on path C:\Users\me\AppData\Local\Docker\wsl\data is taking up 160 GB of disc space. k. 1 Distro Version Ubuntu-20. Docker Desktop creates the VHD that docker-desktop-data uses, but it probably relies on WSL to do so. As an emergency measure I pushed Ctrl-C. / (in an effort to see all disk space usage by Ubuntu) returns a size of ~39GB, and I am unable to find what's occupying the rest of the space. The first step Sending build context to Docker daemon takes 16 GB of space; The step ADD . I reset Docket to Factory and still the CPU pegged at 80% or Docker taking all space 100%. Nothing seems to work. Eventually, it frees 16 GB If Vmmem is using too much memory, here are some steps you can take to manage its resource usage: Adjust WSL Memory Allocation: If you're using WSL and Vmmem is consuming too much memory, you can adjust the memory allocation for your WSL instances. When I call docker build . WSL 2) may start to eat away at your hard drive space. docker xxx prune commands will clean up something unused, such as all stopped containers I notice too that memory tends to be used high, though I never run into memory issue. It's also very difficult to measure the exact disk space utilized by any given Windows feature since Windows is constantly consuming and releasing disk space for other purposes as well. exe (Docker daemon). raw 22666720 Docker. That folder contains a few 30-40GB tar files. However, even after closing docker I have Docker Desktop v 4. Let Luckily, you can reduce its size manually by calling this command in PowerShell (as Administrator): Optimize-VHD -Path c:\path\to\data. Even with the file settings & multiple restarts after Docker Desktop has been running for a few days it will say in Task Manager that it’s using 6GBs but Resource Monitor will show Vmmem using as much as 18GBs. Probably going to have to be a feature request to the Docker Desktop team and/or the WSL team. Start Docker (may need to run wsl --start first) Docker takes a conservative approach to cleaning up unused objects (often referred to as "garbage collection"), such as images, containers, volumes, and networks. I cannot find it documented anywhere) limitation of disk space that can be used by all images and containers created on Docker I purged my data using docker desktop to reclaim space and I went up to 40GB. I was guessing whether move wsl to another, possibly bigger and empty partition. 3: This occupies all my disk space and my task fails. Here is how I was able to free up over Shrink your WSL2 Virtual Disks and Docker Images and Reclaim Disk Space. So what I think has happened that since I pushed Ctrl-C in panic, docker compose did not perform any sort of docker system prune, as every 'delete' (especially bulk delete as in this case) operation, is risky and may have unforeseen consequences. Then I executed docker system prune to no avail, then Docker Desktop Disk space extension to no avail. The folder also contains a Dockerfile and a requirements. vhdx in AppData\Local\Docker\wsl\data is still present and I can't remove it due to it still being used. I ended up getting 50gb back. But it seems that even with all those commands, sometimes you need to start with a clean slate. I found out that the MsMgEng. The docker-desktop-data vhdx is normally in this location: Reclaim disk space by compacting the Docker Desktop WSL disk image. Deleting that file, though, will not recover the space in Windows (but will in Ubuntu). When I run “docker commit ”, it fills up my hard drive with no way to clear it out. After you've removed the files from the VHDX, you're going to need to shrink the VHDX file too. For each type of object, Docker provides a prune command. Now any developer who uses many software as part of their development process would agree that this space is grossly inadequate. Docker persists build cache, containers, images, and volumes to disk. Commands below show that there is a serious mismatch between "official" image, It would be possible for Docker Desktop to manually provision the VHD with a user-configurable maximum size (at least on Windows Pro and higher), but WSL automatically # Space used = 22135MB $ ls -sk Docker. This is why it requires user consent to proceed. 35. This has a side benefit of removing all of my images and containers. But the ext4. Any advice? I made a docker compose build command and it downloaded half of the internet, filling up my disk. After WSL 2 integration, I am not able to find that option. windows. But now my disk image is Your post is a bit confusing, and I actually closed it as a duplicate before realizing that you aren't asking how to reclaim unused space, but rather it seems you are asking what is actually taking up the space in your WSL disk image in the first place. Kubernetes/Docker uses too much disk space. We’ll We'll go over how to regain lots of disk space by compacting the VM file that Docker Desktop creates. My As of July 2020, it’s easy to get in a situation where WSL 2 will eat up all of your disk space, use 80% of your memory and get poor file I/O performance when accessing mounted drives. OFC it might come in handy at times but should be randomguy Asks: Docker taking up too much space I am using Docker on Windows with WSL 2 backend. Docker Desktop uses a VHDX file to store its items on and you'll only remove files from that virtual hard drive. Modified 8 months ago. Even after clearing deleting the files, the disk space remains occupied as it has been allocated to the disk image. /model takes 32 GB of space. 102. exe (Defender) process was scanning the dockerd. At the moment I'm using phpstorm, and did a dump/load of a database. "P:\Users\your-username\AppData\Local\Docker\wsl\data\ext4. Hi, I’ve been using docker compose deployments on different servers. Also, many times installing from pipenv takes time, especially locking. You need to compactify the disk image using what has been suggested here or here. The hard disc image file on path C:\Users\me\AppData\Local\Docker\wsl\data is taking up 160 GB of disc space. It basically boils down to doing the following in powershell- It works OK normally, until I run out of disk space Even when the container is shut down and removed, I still have 95GB of data in c:\Users\me\AppData\Local\Temp\docker-index\sha256 . It will happen even if we will decide to jump into Linux distribution and remove a lot of unnecessary files. But my Ubuntu is already 60 GB so, am unsure how much time it will take to backup tar and how smooth it will be given that my C: drive is already full. 19044. I installed docker on windows home which uses WSL2 as a backend. Open up the docker settings -> Resources -> Advanced and up the amount of Hard Drive space it can use under disk image size. I observed that docker even tends to use swap space. I think this happens because windows allocates some space to the disk image of wsl. There should be a command to list and remove whatever artifacts are created as part of a “commit”. Removing the cruft from Docker Desktop doesn't help much though without the next step. Below is the summary of what I found. Ever. It's not just Docker, but WSL2 and the VM using too much memory. Automating it and thus removing the need for the consent (with --force option) may cause harm to less aware Docker users. Docker taking too much space, even after removing all the images and containers. vhdx" -Mode Full, this will resize the vhdx images; I really like WSL/WSL2 in Windows - it provides a lot of features with minimal performance impact (WSL2) and I can still use Windows app. How do I do that? When I look in Settings, I Following the advice on How do I get back unused disk space from Ubuntu on WSL2? I set my WSL disk image to sparse with wsl --manage <distro> --set-sparse true. In combination with Docker, it can handle a lot of things and it's much better for me than for example MacOS. Only a "purge data" command on docker desktop does seem to do the trick. Still the vhdx images are too big. Here’s how you can do it: The file appears to be 512MB, but du (disk usage) shows that it really takes 0 on the disk. I have my docker taking less than 2% cpu now. I run all the prune commands and it reclaims 0B. Note down the new size in MB. I just have one problem and need some advice, for the past month docker has filled my C Drive through it’s WSL, and I cant seem to be able to get rid of that, I have cleared all images, volumes, containers and everything. So when you view the filesystem through the \\WSL$\ network share, it's simply showing the maximum possible size to which the virtual WSL2 disk can grow. tried running: docker system prune --all Restarting the pc. There are ways to manually shrink it if needed to reclaim space on the Windows drive. Even after deleting all the images and container, docker is not releasing the free disk space back to OS. I am having issues with too much space utilized by docker and wsl2 *. However, since doing this a process called vmmem seems to be consistently consuming a lot of computational resources. But. 04 Other Software Docker Desktop: 4. For those of you that run Docker Desktop on Windows with WSL2 integration, this is for you. 10. Step 2: Clean up the WSL installation for Docker Hi everyone, happy to see many people using and loving Docker as I do. One problem I discovered last time is space consumed The good news is that resolving this memory consumption issue is straightforward. CPU usage was 98%. For setting memory allocation limits on containers in previous versions, I had option in Docker Desktop GUI under Settings->Resources->Advanced->Preferences to adjust memory and CPU allocation. You can mount a bigger disk space It definitely gets worse the more times I build Docker images. This virtual hard disk file can automatically grow when it needs more space (to a certain limit). 9. Docker Hard Disk Image File Being Too Large. I assume that Docker is storing all the image and container files on my C:\\ drive or some alias to it - although I have yet to find where. Also, it will still be consuming space on I noticed that the space on the hard disk that docker WSL uses doesn't shrink. vhdx, and its the virtual disk that the Docker Desktop WSL2 instance uses. Over time, these things can take up a lot of space on your system, either locally or in CI. To isolate the issue, run task manager while you're doing a very slow docker build. You mention that your image is taking up ~40GB, and that it is showing 4% usage of approximately 1TB (the normal sparse size for a Version Microsoft Windows [Version 10. On each of the server I have an issue where a single container is taking up all space over a long period of time (±1month). The VM is lightweight, but you're still running entire other operating systems within it and docker itself takes up memory and CPU. Your Windows build number: 18917 What's wrong / what should be happening instead: WSL 2 starts using huge amounts of RAM after a while, just using it like normal. vhdx" -Mode Full, this will resize the vhdx images; I ended up getting back 50GB of space after running these commands. There are various suggestions you can find online, including lowering how much memory Docker uses, but I found that those didn't actually fix the problem. After some research I found a nice step-by-step instruction by Stephen Rees-Carter how to shrink the used space by wsl2: How to Shrink a WSL2 Virtual Disk A rough explanation: WSL2 runs the Linux kernel in a VM. . If I run docker image prune -a unnecessary images are purged, but the space is not reclaimed: I recently updated my Docker environment to run on WSL 2 on Windows. txt. After updating . Windows hasn't fixed this problem yet, but Vmmem using too much memory is caused by WSL2 and Docker. When I look at process hadnles Its still being used by system which is not telling much. There are ways to reclaim the space and move the storage to some other directory. The containers are much lighter than equivalent VMs, but the containers are running in the WSL2 VM. It Note that space, once consumed, is not automatically released. a. vhdx and follow the wizard to increase it to whatever size you like. Above commenter is right, 4GB just isn't going to cut it. It's resulting in build processes slowing down to somewhere between 1/10th and 1/50th the speed they run at when There are at least two directories where docker can fill up space. If I am low on disk space and use WSL2 to build a project that uses a few GB of RAM, this memory usage would also use similar amount of disk space on the host.

The WSL2 virtual disk image that contains Ubuntu is a dynamic Hyper-V virtual disk. As in, my computer is I cannot find it documented anywhere) limitation of disk space that can be used by all images and containers created on Docker Desktop WSL2 Windows. wslconfig to be: [wsl2] memory=8GB swap=2000 processors=4 and then restarting Docker, the CPU consumption was still over 80% and there were 5 Docker Desktop processes (each taking 17-18%) in Windows Task Manager. Docker container taking 27GB on disk while docker container ls --size only report 500MB. If I run docker image prune -a unnecessary images are purged, but the space is not reclaimed: ronald@Ronald:~/$ docker image prune -a WARNING! This will remove all Yes, Docker use /var/lib/docker folder to store the layers. I’m somewhat shocked that this user journey is even possible. Browse to C:\Users\[Your User]\AppData\Local\Docker\wsl\data Select ext4. 1 Repro Steps You simply need to build docker images several times. That said, here are some measurements done on Windows 11 today: Short form: The WSL feature and kernel take between 100-200MB of space. --Nico Reducing the vdisk max size only limits the disk growing too large and wasting disk space on the host, but sparse vdisk makes that mostly unnecessary. To my knowledge that in linux system swap space is the memory space which will be used when much more memory in the system are needed. It would be possible for Docker Desktop to manually provision the VHD with a user-configurable maximum size (at least on Windows Pro and higher), but WSL Reclaim Docker WSL Disk Space I ran out of system SSD disk space on my Win10 PC at home and tracked a large share of the usage to a vhdx virtual disk image file in a Docker Desktop folder. raw # Discard the unused blocks on the file system $ docker run --privileged --pid=host docker/desktop-reclaim-space # Savings are Other answers address listing system memory usage and increasing the amount of Docker disk space in Docker Desktop: The docker system df command can be used to view reclaimable memory --Abishek_Jain. Vmmem Due to an increasing database size in the local docker environments in my work project, I have been attempting to increase the maximum size of the virtual disk space of WSL2 for Docker from 256Gb to 512Gb. I see that it is 251G. Fortunately, there is a quick solution – we can use diskpart includes in Windows to reclaim some space. LOCALAPPDATA\Docker\wsl\data\ext4. I seldom observe much swap usage in linux system. Docker Desktop for Windows v2, which uses WSL2, stores all image and container files in a separate virtual volume (vhdx). I reset Docket to Factory and still the CPU pegged at 80% or It was taking over 10 minutes to do a restore that would take about 5 seconds on my own machine. When analysing the disk usage with du -sh most of the usage is located in var/lib/docker/overlay2, but the numbers do not add up. vhdx" In my case docker is using up about 27GB of disk space in this file. Now my environment is running fine but the ext4. xyvfr gekly hcdw kuxaho lvai zkga gzhltzya mrudeff ejlw dnn
