Hello, IDK if you have solved your issue, but I currently develop on Odoo on my M1 mac, basically, I made a duplicate of my terminal app, and in the get info menu, you can click on "Run using rosseta", then, I installed a second instance of Homebrew using this terminal (It installs it somewhere else on the system when it's an x86 app), and installed pipenv (similiar to venv) for python, Then on a directory, I ran pipenv shell passing the Python version that I want to use (must be different than system default), and pipenv downloads that python version but using x86. After all of this is done, you will see a Pipfile on the directory you were on, to activate this environment you just have to type pipenv shell on the same dir as the Pipfile, when using this environment, all python code will be executed using rosseta, so you can install requirements and run Odoo without containers or some other workarounds. If this is useful and needs more explanation, let me know.

You would likely need to build a custom Docker image. In my case, I had to build a custom Docker image for Odoo v10 CE.

You can use a sample Dockerfile I've created here:

Hi,

You can run try to run the command below, seems to work correctly when using the --platform argument as well as download the m1 preview image.

docker pull odoo:14 --platform linux/arm64

Same thing for postgress DB image

docker pull postgres:12 --platform linux/arm64
