None of the existing methods account for this very well, even the relatively new mount options to try and performance boost either reads or writes don't particularly help because of the relative symmetry under certain configurations. for Magento2. I love you for that one, thanks for sharing! The main advantage of such a solution is overall Mac performance while using Docker. I Between Rails hot code reloading, which has a semi-hard dependency on working filesystem events (the polling alternative can eat as much as 20% of system CPU) and Bootsnap, which is a caching loader which tries to speed up booting Rails by bypassing the parsing step (and caching compiled btyecode on disk) which means that booting a Rails app with bootsnap loaded writes as many file as it reads (sometimes), but other times (e,g warm start) has a very different read/write ratio. POSIX file-systems (most of the ones you know and love) even moreso, as POSIX specifies some guarantees about what it means to take certain operations, and those requirements are fairly rigid. In my opinion, mutagen is the best option to improve performance, if you want to stick with Docker for Mac. Improvement is very noticeable. (rename, symlink, etc being also common). I tried without the :cached attribute, and the performance is still terrible, so I do not believe that's the issue. As you can see, the difference between different volume options is not big. dependencies like a database, a Redis, or a mail server made it become a solid (Using MacOS 12.4, DD 4.9.0, git 2.30.2, Debian 11 Container). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Actually I did that already, such that filenames und folders are randomly named and file contents are empty. I am having an issue with permissions with VirtioFS enabled and I wanted to check one of the attached dockers builds which might fix the issue. But, I tracked down the reason a little bit more. For some applications, this wont be a big problem, but all apps which perform many I/O disk operations will be affected and probably not usable. @robsontenorio Strange, works for me with same specs. The way I did this is to ssh tunnel port 80 from my host (MacOS) to the client (Linux), like this: First of, good job, but im having issues with -v/--volume mappings, no error, no warnings, shows my some of my sub directories, but non of the files. I still use my MacBook Pro, but not for anything Docker related (my day job, basically). Looking forward to the follow-up post regarding files syncing, since it's what I need for our project. It is the only working solution i have found, i.e. As you can see on the above chart, Docker for Mac is slow, very slow. Magento 2 seems to be an ideal use-case to test the folder sync issues. Have a question about this project? It's not that bad, doing it for 20+ years as a freelancer. HFS+ for example is case insensitive (optionally), and the way file-system events (notifications about changes to files and directories) don't work quite the same, and probably other aspects I'm forgetting, such as whether or not files can be atomically replaced, or deleted whilst still being open, or whatever else on the long-tale of occasionally important behaviour. Only for comparison, here is the difference between a previous test (my first comment just after trying VirtioFS for the first time) and a current test. I have hand-fudged the socket to be created in /tmp and that solves the issue with VirtioFS enabled. Tests were performed on one of our projects, in the dev environment. What is interesting for all Mac users is that Mutagen can be used with Docker on Mac, as a tool for syncing files between host and docker volume. Here's how our stack from before looks with two extra levels of VM, and file-sharing: In the realms of shared file-systems, the bridge between our Docker VM (and the containers it runs) and the host system file-system must be some kind of network, or demi-network based file-system. From time to time there is a need to build Docker containers from scratch. Im not sure if you know about it, but Im sure you should! Running "git status" just now took 6.73 minutes was compared to 44 seconds without VirtioFS (using gRPC FUSE). I maintain a personal Ruby-on-Rails application in mixed mode, Ruby language and Ruby-on-Rails run natively on macOS Monterey 12.4 with only the Postgres database running under Docker 4.8.2 (79419). Artifacts and caching directories like var/cache, generated, node_modules, vendor, etc. Is this something that will be addressed in future releases of the new FS? It improves performance a lot. Hopefully, a native integration will make this as simple as adding a flag to your volume. Thanks to that you can work on your project on your Mac like always and all changes will be sent to the virtual machine, where you have Docker running. As I mentioned at the beginning, use Linux instead. That's obviously not workable for a development workflow. This chart presents mutagen performance in comparison to previous results. running tests on such a simple code. The two different computers I used to compare test execution time: The three different environments I used on each computer: I bootstrapped an empty Rails I am finding on my Apple Macbook Air with M1 chip that VirtioFS performance is inferior to the default (gRPC?) It is always taking a lot of resources, and it is almost impossible to use a computer during this time. (the tech that virtualizes hardware, examples would be VMWare Fusion, Parallels, VirtualBox, etc). dont have to. Is this improvement also works with Kubernetes (via Docker for mac) ? Could you elaborate? On macOS, it's xhyve, nothing spectacular or special about xhyve, as far as I'm aware, except it's bundled basically as part of macOS by Apple as Hypervisor.framework, and xhyve just uses that. Once unpublished, all posts by leehambley will become hidden and only accessible to themselves. It completely blew up my mind, outstanding performance! What's Virtualization.framework exactly? Trust me, this is not a convenient solution, especially in my case (flexible working hours). In that scenario the file-system stack looks something like this: The story doesn't change much if using Docker shared volumes mapped between the container and the host because the partitioning of the filesystem that is visible to the container is all magic of kernel namespacing and clever use of "overlay" filesystems, which are a way to "stack" multiple, possible sparse directories on top of one another to give a union view of all the parts of the stack. In experimental features you can use the virtualization.framework and I think they run a Linux VM using the virtualization.framework as well. The family of file-system related "system calls" (syscalls), runs a breadth of ~15 things, open, read, write, stat, lstat, access, and close being the most frequently called ones. Common known solutions are NFS and CIFS (Samba), however Docker provides their own osxfs (closed source), and in their edge channel provide one by the name of gRPC-Fuse (also closed-source). In the context then, again of Docker (for Mac), I did some profiling of the file-system performance but not a the level of raw read/write performance, but indeed a level lower. This is now out on Docker Desktop Edge, we are after feedback on the UX, the functionality and the performance! System this error occurred on is an M1 mac mini, macOS version 12.3.1. If there isn't an ARM version, it would be easy enough to make. and investigate a few options to improve Docker performance on macOS. When you are a software developer, what's wrong with working directly on a Linux distro on a x64 machine where you can run everything natively (even containers) and harness the full power? Hey all, we're still really stymied by docker/for-mac#6243 when working with our Postgres databases locally, is there any update on that issue or any workarounds we can use? Configuration is very easy, you can have different ones for each project. The Docker Desktop client does as well. Why? @nicholasruunu are you in same macOS 12.4 (==> 21F79 build) ? Docker is very convenient to automate things, it has an x20 incidence on Usually i exclude these directories so there's not need for sync. with more significant projects. I was trying to separate work from after-work activities by using two operating systems, switching from one to another based on what I wanted to do. That's doesn't seem right. Thanks! and only accessible to Lee Hambley. should basically persist on the container, however the issue that @Jean85 pointed out that you miss IDE functionality is definitely valid. The text was updated successfully, but these errors were encountered: These issue are still happening, so can they be added to this or new cards made to include them? It is really fast, and it does not influence performance. I was having pretty good results on Docker + WordPress using the new experimental options; however, recently, I started noticing some random slowdowns here and there. then used to run tests: Dont use Docker Desktop on macOS. Thanks for keeping DEV Community safe. There are filed issues for those problems, but I can't find them right now. If you leverage NFS based file sharing, this should speed up your perf substantially. Built on Forem the open source software that powers DEV and other inclusive communities. Next.js version was 12. to your account. Such an approach has one more advantage, it is easily scalable, if you need more RAM, CPU or disk, you can add it. Based on that experience I decided to switch to something which combines some of the good features of Linux and the usability of Windows, and I bought my first MacBook Pro. Worse, because the invisible virtual machine (Linux), and the host use different file-systems (say EXT4 in the VM, and HFS+ in the host), not all concepts are portable. Compiling a small Java application took over 5 minutes compared to 53 seconds. I've just begun experimenting with using VirtioFS for a Rails project on my M1 Max. At the very beginning, I was a Windows user and did not need a lot of time to realize that it is not well suited for my programmer career. I think the issue was the the volumes for node_modules and so on suddenly didn't mount anymore. Thanks for the write up, Id really like to move my apps to Docker but the performance on Mac has put me off before, so this is definitely intriguing. Restart the server to see the changes in effect , which apparently is connected to the Next.js process fs.watchFile. For example: Anyone has a clew why this could be the case? Are you sure you want to hide this comment? Thank you!! It may also be related to the network connection. Templates let you quickly answer FAQs or store snippets for re-use. One thing worth mentioning here is also the consumption of RAM and CPU during this process. Only issue I'm having is that I have to sigterm my containers started with docker compose up. This is exactly the experience we want! It is not the cheapest one, but probably it will be cheaper than investing a lot of money in a MacBook with enough disk space, RAM, and CPU to handle Docker, IDE, browser, and other tools at the same time. You can test your application on your normal browser by just going to the virtual machine IP address. You will thank me later ;), See also my update on that topic for 2022: Docker on new MacBook with M1 Pro. N/A @jnfDev Would it be possible for you to add the following information to your comment? No configuration is required and you can still use delegated, cache @mauri-brioschi osxfs is (much) more performant than nfs in my experience. And how to make it way faster? @seneracula thanks for the report, could you add details about a way to reproduce ? All you need to do is to install it and use mutagen-compose up instead of regular docker-compose up. coding. What are you trying to do, and why is it hard? Turning that off with set backupcopy=yes is an acceptable workaround for me for now. The important thing is though, that we no longer share any resources between the host and the VM. Unfortunately, there is one big drawback of this solution, when you need to resync the whole project or send many files at once, PhpStorm will send them one by one which can take some time. Mutagen offers different modes https://mutagen.io/documentation/synchronization and ideally we should have access to all of these modes. The bug was reproducible when I re-enabled VirtioFS, so hopefully it would be reproducible for others as well. Accesto is a butique software house focused on software craftsmanship and partnership. I'm mounting my source code using a bind mount. on Mac has had some performance issues since the beginning. Update: we are now looking at using GRPCFuse rather than mutagen as a simpler path for perf improvement. ), incredibly complicated and flimsy docker usage is. Solid State Drives (SSDs) cover all our our common use-cases, and by virtue of being absolutely screaming fast, file-systems in general were propelled a decade into the future "by magic" because of the underlying technology. For your comparison, have you tried running Docker directly on the M1 Mac? Caching these directories really solve the problem? many issues. To start synchronization just run mutagen project start. Could anybody help with it? Once unpublished, this post will become invisible to the public Just tried latest macOS 12.5 beta 2 and newest Docker Desktop 4.9.0 , but no lucky :(, Found a workaround docker/for-mac#6331 (comment). M1. Most places I know are still using NFS, with polling, and trying to tune the fsattr cache times to get a reasonable balance of developer experience (speed of code reloading) vs. performance (outright speed), but it's a tightrope. Well occasionally send you account related emails. Unflagging leehambley will restore default visibility to their posts. Everything has been working well. when seeding my database via Rails ActiveRecord. Therefore I tried to wipe all my data for Docker Desktop on my Mac (following https://www.mytecbits.com/apple/macos/clean-way-to-uninstall-docker and docker/for-mac#6208 (comment), maybe not the best guide ). Docker supports three options for setting consistency on volumes definition: Setting different volume options of the application may influence performance, and some sources say that such change may make Docker on Mac faster. (single responsibility, At Accesto we recently came up with a project release checklist that helps us to make sure that we did not miss anything. You can find the whole example docker-compose.yml file here. This issue was solved by disabling VirtioFS accelerated directory sharing. docker/for-mac#1592 If the application is not working much with file system (etc cache) you might not notice any boost at all. This file was consistently reporting changes to an unchanged file no matter what we did, while inside a docker container. File system performance is big issue on Mac,our goal improve web page refresh for web languages like PHP from 2.8 seconds to 0.2 seconds, Are you currently working around this issue?
