In order to allow remote access to.TLDR: Use Linux instead -) Why is Docker on Mac so slow?Docker Toolbox is a good option but currently it seems like Docker for Mac/Windows is becoming better and Docker is investing a lot of time polishing the app. Ubuntu Server is geared more towards advanced users. This support extends to all Docker client platforms (Linux ®, macOS, Windows, etc.), Docker daemon setups (local, remote, VM, Hyper-V, etc.), and Docker container types (both Linux and Windows containers are supported).For example doing a command like this docker run -ti -mac-address. Mutagen has support for synchronizing files and forwarding network traffic to and from Docker ® containers. Docker® container endpoints.Why not buy a ânormalâ computer with Linux on it?I dont consider the native Docker on Linux for now because I need softwares that are not available on Linux everyday. For some applications, this wonât 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.Docker pull Pulls an image or a repository from a registry.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. Docker rm Removes Container. Docker rmi Removes Docker image. Docker stop Stops container. Docker start Starts one or more stopped containers. I currently use Docker Desktop for Mac on my MacBook Pro 13' mid-2012 with 16gb of ram.docker run Runs a command in a new container.It, of course, took me a while to get used to a different system but I still like it and donât 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. I was trying to separate work from after-work activities by using two operating systems, switching from one to another based on what I want to do. That contains the commands that Docker will run to build the image.Unfortunately, I had only one computer for work and entertainment, and for this second task, Linux was not good enough for me.
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. Are there any solutions to make Docker on Mac faster?As I mentioned at the beginning, use Linux instead.Ok, letâs put the jokes aside (is it really a joke?) and investigate few options to improve Docker performance on macOS. Mac arcade emulatorcached - the hostâs view is authoritative (permit delays before updates on the host appear in the container) consistent (default) - perfect consistency (host and container have an identical view of the mount at all times) 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 Iâm using every day in my work.I also measured the time needed to build a docker image from scratch. 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. In my opinion mutagen is the best option to improve performance, if you want to stick with Docker for Mac. Improvement is very noticeable. This build-in tool is called Deployment and allows to sync files for example by SFTP. But maybe not everyone knows that it also supports file synchronization. Files synchronization PhpStormAll PHP developers probably know this IDE and probably most of you are using it. It is really fast, and it does not influence performance. You can test your application on your normal browser by just going to the virtual machine IP address. 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. ![]() Commands For Docker Archive To ImproveThe 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 wonât 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.Iâm 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. 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 Iâm using this setup, I switched from VirtualBox to VPS a few months ago and Iâm very happy with that.
