It does have some nice perks of one-Touch Kubernetes-but otherwise you get the pain of macOS accessory limitations (have to use special docks or actual Thunderbolt displays for multi-monitor when in the office.Running Docker on VMware virtual machines is not only possible but many IT teams rely on this setup for deploying their applications. I’ve never benchmarked it, but I’ve heard numerous people complain about how bloated and slow Docker for Mac. The virtual machine runs the Docker.Docker for Mac like other Docker solutions just runs a VM with Linux.I found that if an ARM-native version is not available for an application, the emulated one works just fine and there’s no performance drawback that I can notice. CompatibilityAll the software I need to use “just works”. This is why I think ARM is the future, even if it might take a decade for the mainstream cloud to migrate over.My Xeon Linux-based workstation suddenly feels old. It also means longer battery cycles for non-cloud use-cases (less waste, more bang for the buck). A number of fast-growing tech giants (besides Apple) are pouring a ton of money into making ARM work for a ton of use-cases: Nvidia (trying to buy ARM Holdings from SoftBank) and Amazon (deep investment in the new Graviton processors) are the two that primarily come to mind.As you might know, in processors low energy consumption (and low heat dissipation) often equates to the ability to scale processing efficiently for large workloads.In some cases, I had to install preview editions of software, but everything worked very well for me. We engineers sometimes use very low-level system capabilities. However, you can also install it manually via /usr/sbin/softwareupdate -install-rosettaThe tools you use for development are likely still catching up to this architectural change, and will be for some time. The OS will automatically detect that Rosetta is needed and prompt you to install it.As mentioned on the documentation page, there are some limitations currently related to HTTP proxy, VPN clients, and performance, but the Docker team is making progress fast. You can download the Docker App for M1, which is in preview. Emulation doesn’t have virtualization features, which the Docker app requires. M1 native version is a must. The arm64 native version is available on the VS Code Insiders and works really well. The amd64 version works perfectly well, however, the terminal will be an amd64 process, which may cause some programs to also run as amd64.
![]() It seems that there are no official OpenJDK builds for aarch64, however there are some community options. I had issues with the JVM, experiencing random process hangs. I built binaries in Docker and ran them natively. 1.16 RC adds support for building darwin/arm64 binaries. ✅ Earthly ( v0.5.1+ now supports M1 natively - just brew install earthly/earthly/earthly)I should also mention that during the first few weeks I had some issues with audio skips when using Bluetooth, but an OS update fixed it (just like Apple promised).I also use a ✅ YubiKey 5C Nano and a bunch of random peripherals like a ✅ USB microphone and a ✅ dock plugged into Ethernet.Languages and frameworks I’ve tested - most of them in Docker containers: ✅ Brew (native, encountered some issues with git, but was able to fix them) ✅ Elixir works fine on native architecture in Docker. Did not immediately work natively (and I did not investigate). Net works fine when emulated as amd64 in a container. ✅ Rust works fine on native architecture in Docker. ✅ Cobol (yes, really) works fine on native architecture in Docker. ✅ Ruby and Ruby on Rails works fine on native architecture in Docker. ✅ Python works fine on native architecture in Docker. ✅ JavaScript / Node works fine on native architecture in Docker. Here’s how I can tell that Zoom is an ARM process, while Spotify is an X86_64 process. If it says Intel, it’s X86_64. Rosetta 2 is that good.The easiest way to tell the difference is by opening Activity Monitor and looking at the Architecture column: if it says Apple, it’s ARM. This is pure speculation, however, I’ve not researched this.(In any case, a very impressive effort to switch architecture so quickly for a project that hosts so many packages!)Back to fixing the issue now. Not sure what the cause of this is, but it could be the fact that brew has been adding native arm support for many packages in the last few months and it’s possible that this migration resulted in some inconsistencies. Terminal showing the output of uname -m as arm64 Brew IssuesOne issue I encountered on both my M1 laptop and also a MacStadium MacMini instance that we use for Mac testing is that Brew randomly started to complain about git missing. Arm64 and aarch64 are both ARM - uname on Mac just reports it differently compared to Linux. It’ll say either X86_64, arm64 (Mac) or aarch64 (Linux). Bully full game download for androidI was not as comfortable doing that on my laptop after having installed so much via casks. On the MacStadium instance, I was able to just uninstall brew and reinstall it and everything was fine. However, the issue was still there. Easy: xcode-select -install. Does Docker Use A Vm How To Fix ItYour mileage may vary, however, if you are curling some binary that may need to switch from X86_64 to aarch64 in its URL, or if you’re doing lower-level stuff. If you’re building an image, by default it’ll use your native architecture to execute the build (arm64) and most things will magically just work. Most official images are now supported on arm64 too. Making use of multi-platform images seems daunting at first, but really it’s actually pretty simple.The Docker for Mac app comes packed with QEMU out of the box - so Docker is able to run either arm64 and amd64 images. (If anyone reading this knows what’s up with my brew’s git and can tell me how to fix it, ping me on Twitter: Using DockerThe Docker preview worked almost flawlessly for me from day 1. Terminal showing the output of uname -m for different container platformsDocker Compose will happily run a mixture of various architectures. You can also override the platform via -platform=linux/amd64 if you’d like to run the amd64 version specifically. For more details on building multi-platform images see Akihiro Suda’s blog.If you docker pull an image from the registry, it will again default to your native architecture (if available), unless you specify -platform=linux/amd64.If you docker run an image, it will default to whatever version of the image you have available locally or it will attempt to pull the arm64 version from the registry. Instead of the usual docker build. ![]() The rest will run natively. This is in Beta, so if you end up giving this a try - we’d appreciate any feedback you can give us via GitHub issues or in our Slack.One useful Earthly trick I’ve used a lot is that if one part of your build has not yet been ported to amd64, you can simply mark it as -platform=linux/amd64 - and thus only that part will execute on amd64. Using EarthlyWe’ve added support for Apple M1 in Earthly and so far it’s working wonderfully. After some head-scratching the issue was resolved by switching to the ARM-based VS Code Insiders edition. In some situations, this led to some strange issues when running Docker, where QEMU was acting up with segmentation faults.
