Ext4 Docker Mac Will Not

Ext4 bs1M count ( (4.September 2020 Update: Alas, Docker for Mac will not be getting built-in Mutagen support at this time. I am doing some experiments with Android using qemu and gem5. Your host should be 172.17.0.1 and your first container should be 172.17.0.2 if everything is normal and you didn't specify any special network options.TLDR: Use Linux instead -) Why is Docker on Mac so slow?5 or later, but it is recommended to use Mac OS X 10. Usually, the default docker ip range is 172.17.0.0/16. Probably is better to filter: docker inspect grep ''IPAddress'' head -n 1.

Docker provides methods for managing OS-level containers and is built on top of Linuxs native features for OS-level containerization. Why not buy a вЂњnormalвЂќ computer with Linux on it?3 Answers3. For some applications, this wonвЂ™t be a big problem, but all apps which perform many I/O disk operations will be affected and probably not usable. These are related to volume performance, the way volumes are mounted, and the underlying osxfs filesystem. Use volumes, There are different volume types like nfs, btrfs, ext3, ext4 and also.On Mac has had some performance issues since the beginning. It was painfully slow, and the community finally got a cached mode that offered a 20-30x speedup for common disk access patterns around.docker-compose super slow on macOS Catalina Issue 6956 , when i do.

Everything has been working well.And then Docker has become a very popular tool, we started to use it in our company and problems started. It, of course, took me a while to get used to a different system but I still like it and donвЂ™t want to change to anything else.This was the time before Docker, so I had no performance issues with my work-related tasks. Trust me, this is not a convenient solution, especially in my case (flexible working hours).Based on that experience I decided to switch to something which combines some of the good features from Linux and usability from Windows, and I bought my first MacBook Pro.I was very happy about this decision.

It is also an important factor because it would be nice to not be forced to take one hour break just to build a new image.In order to have some point of reference, I asked my colleague to test his setup, computer with much more RAM, CPU, and SSD disk running on Linux.Docker for Mac - play with volume configurationDocker supports three options for setting consistency on volumes definition: The same setup IвЂ™m using every day in my work.I also measured the time needed to build a docker image from scratch. Tests were performed on one of our projects, in the dev environment. I was testing the same Rest API endpoint with Apache Benchmarking tool.One hundred sequential requests, without concurrency. Benchmark methodologyI used the same methodology for each setup.

Improvement is very noticeable. delegated - the containerвЂ™s view is authoritative (permit delays before updates on the container appear in the host)Setting different volume options of the application may influence performance, and some sources say that such change may make Docker on Mac faster.If you are using docker-compose then just add the proper option to the volume definition.X-mutagen : sync : defaults : ignore : vcs : true code : alpha : '.' beta : 'volume://code' mode : 'two-way-resolved'You can find the whole example docker-compose.yml file hereOf course, you need to install mutagen first and start the daemon.Looks a little bit complicated but it is not, and the profit is worth it.This chart presents mutagen performance in comparison to previous results. cached - the hostвЂ™s view is authoritative (permit delays before updates on the host appear in the container)

Files synchronization PhpStormAll PHP developers probably know this IDE and probably most of you are using it. I will not describe the whole setup here, it is not in the scope of this post, but because file synchronization performance is a main topic, I can briefly mention what tools I used for that purpose. set up the virtual machine with a whole Linux based environmentBut you need to do this only once. Linux on VirtualBoxI came up with this solution before mutagen was available and I had been using it for a quite long time before I switched to a different (but similar) approach.It is a little bit tricky to configure because you must: I tested two approaches, VirtualBox and VPS. LinuxI was not joking, seriously Linux is also an option for Mac users.

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. It is easy to configure, it supports automatic upload and many other features. This build-in tool is called Deployment and allows to sync files for example by SFTP.

Just place a file called mutagen.yml inside project directory with content like this:Sync : defaults : ignore : paths : -. It can also handle such tasks.Configuration is very easy, you can have different ones for each project. MutagenI had been using PhpStorm for some time for the files sync and then I decided to try another tool, mentioned here Mutagen. 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. It is really fast, and it does not influence performance.

The result for mutagen on Docker for Mac is added to this chart to make the comparison easier.As you can see, the difference between different volume options is not big. Time for a benchmarkI also tested different volume options on this setup. So syncing the whole project wonвЂ™t take so much time like in the case of PhpStorm based sync. It also collects changed files and sends them as an archive to improve performance. From now your files will be automatically synced with a virtual machine, there are almost no delays and it is a very stable solution. To start synchronization just run mutagen project start.

The main difference is that VPS can be accessed from a public network, so it would be nice to properly secure it with a firewall, VPN, etc.So it is not trivial but I think that everyone with basic DevOps knowledge will be able to configure such an environment.IвЂ™m using quite cheap VPS, which is not too powerful. Such an approach has one more advantage, it is easily scalable, if you need more RAM, CPU or disk, you can add it.Configuration and setting everything up do not differ much from VirtualBox setup. All heavy tasks can be performed by another machine, Linux based, without performance issues. You can always buy a more powerful machine, but is an expensive solution and also not too eco-friendly if your current Mac is still working fine.A cheaper option would be to outsource Docker related stuff to Virtual Private Server. Linux on VPSDocker is a quite resource-consuming tool, does not matter if you are using Docker for Mac or VirtualBox, it will require a lot of CPU and RAM. I would even say that this difference is within measurement error.

It is generally time-consuming, but can be done in a relatively short time and can also take an hour or more.As you can see Docker for Mac is slow not only in the case of processing requests but it is even worse in the case of building the docker image.Setting up mutagen will shorten this time to a little bit over half of an hour. From time to time there is a need to build Docker containers from scratch. Build time comparisonThis is another aspect I did not mention yet. Everything else works better, each operation you make is smoother and also the computer is not overheating, and runs quieter.Currently IвЂ™m using this setup, I switched from VirtualBox to VPS a few months ago and IвЂ™m very happy with that.

It does not matter if I build a container on VirtualBox or directly on Mac. I assume that VPS has a lighting fast internet connection so downloading all required data from the internet took less time than in the case of other setups that were using an internet connection in my home.One thing worth mentioning here is also the consumption of RAM and CPU during this process. It may be also related to the network connection.

Everything is so slow that the better thing to do during Docker build is to take a break and go for a walk.
