This video was so clear and easy to follow, kudos! I've been confused as buildx is the "new way" to do multi arch images, yet having multiple Dockerfiles or multiple build stages to produce different images (very easy to find yourself in this situation, mind you...) immediately breaks the "new way." I spent too much time trying to figure out how buildx accounts for this very common use case and sounds like the answer is "it doesn't." I guess I'll stick to the "old way" for now (docker manifest) for anyone that didn't watch the whole video.
Thank you very much. Just experienced that pain after moving my workflow on Macbook Air M1. We use some precompiled binaries in our container, so it can't be built in aarch64. For those who wondering, how to built containers in preffered platform with docker-compose: 1. change docker-compose.yml "version" parameter to "2.4" 2. add "platform: linux/amd64" in desired service options 3. rebuild
@@DevOpsDirective I ended up getting an m1 mac mini, even though I agreed with your assessment of why it might not be the best idea for certain dev workflows. But it's great to see that they are making updates to integrate the new architecture.
Nice video! It helped a lot!! Reminder for the newbies like me: do not forget to write the username correctly or else it will give you an "not authorized error"
Dockerized some python script and pushed to my dockerhub. Created ec2 in aws installed docker. Pulled that image and tried to run it. Failed because of architecture. Even tried with --platform arm64. Failed. Now u saved my #a#sss. Thank u so much
Thanks for covering & explaining things in lucid way . Appreciate I am in a situation where in as part of developer's environment , I want to build docker image for one huge multi-language (django-python,java etc) monolith app(for linux os, jailrooted , having diff services like postgres, celery jobs & few java processes in it), which should be compatible with x86_64 intel based & arm64 M1 based mac , as few employees has intel macs , while new ones are getting m1 mac . I guess in my case rather then investing much amount of time on buildx, I should go with an older approach of having 2 macs by my side 1 with intel chip & another with arm64 M1 chip . Also in my case as build process of creating docker image of that monolith app is too complex , I would have to create separate Dockerfile for each architecture. Any thoughts on this ?
Hi DevOps! Amazing Video, very helpful. I have an issue. I'm working on a x86 system and pulled a ARMv8 image. i was hoping to build that image to a ARMv8 device using the host. Is this possible using your same example? Regards and thanks again for the video.
Thanks! You are using the ARMv8 image as the base for a custom image of your own and then want to deploy that as a container onto an ARMv8 device? Does the device already have a container runtime? (docker, podman, containerd, etc...)
What if I do not want to push image to docker hub registry. Want to build it locally and run it locally. My apps seems to be working fine on windows container but not on m1 mac
Hmm, you should be able to use buildx with an M1. There are some edge cases that cause issues but most cases should work. What are you trying to build/run?
Great video!!! If wanting to save money, wouldn't just building with one architecture, such as ARM64, save more money, with less development costs and hosting cost?
Thanks @Joshua! Yes, building for a single architecture is simpler (although with buildx not by that much!) and the AWS ARM servers offer good price/performance relative to intel. One of the reasons it isn't as common to build only for ARM64 is that historically very few developer systems have used ARM and most people want to be able to run a development version locally. With remote development workflows and now the apple silicon macs, we may start to see a shift!
"Error: Error response from daemon: invalid mount config for type "volume": invalid mount path: 'C:/ProgramData/buildkitd/.buildstate' mount path must be absolute" i ran into this error while inspecting the bootstrap... can you help me?
hmm... that certainly looks like an absolute path! I have never used Docker on Windows so I'm not sure if there is some additional nuance to using bind mounts. Does that path exist (C:/ProgramData/buildkitd/.buildstate) on your host system?
I actually didnt know about buildx bake! It looks like it is similar to build, but allows you to build multiple services at once with a docker compose file. Is that right?
In which way do you want to use buildx with docker compose? Compose either pulls an image or builds one for the current platform and then effectively runs it. Of course, you could use docker compose with images build with buildx but I don't see why docker compose would build multi-platform images.
You have to provide a path to the directory you want to build. If you are running the command within the same directory this will just be a period: docker buildx build .

Great overview! Perfect level of detail. Thanks for this video.

Thanks, Paul -- Yes, I think the next 5 years will be a major growth period for ARM!

What is the correct platform the new M1-2020 Macbooks? is linux/arm64 or linux/arm/v7 or linux/arm64/v8 ?
Good question! I am not 100% sure, but I think it would default to linux/arm64

Do you try docker buildx bake command, can provide file to build multi arch config
i just don't know how to write a bake file, I hope have video about that
I actually didnt know about buildx bake!
It looks like it is similar to build, but allows you to build multiple services at once with a docker compose file. Is that right?
@@DevOpsDirective compose file can only build one arch I think, and cam do it using new "docker compose build" command
Nice, sounds useful!
I got an error: docker: 'buildx' is not a docker command. What should I do?
It should be included in newer versions of docker desktop. See: docs.docker.com/buildx/working-with-buildx/#install
So maybe just try updating docker?
can we use buildx with docker compose?
how?
