Failed to run in devcontainer

I’m trying to run Home Assistant in a dev container for add-on development, following these instructions. It seems like it’s unable to download the image, with this error:

24-02-11 14:55:39 ERROR (MainThread) [supervisor.docker.interface] Can’t install ghcr.io/home-assistant/qemuarm-64-homeassistant:2024.3.0.dev20240210: 404 Client Error for http+docker://localhost/v1.43/images/ghcr.io/home-assistant/qemuarm-64-homeassistant:2024.3.0.dev20240210/json: Not Found (“No such image: Package qemuarm-64-homeassistant · GitHub”)

Why is it trying to download from localhost?

This is my first time using dev containers. When I open my repo in VS Code it prompts to Reopen in Container, which looks like it succeeds. When I try to run task: Start Home Assistant, it loads for a few minutes and then shows that error. I’m on M2 MacBook running MacOS Ventura 13.5.2 with Docker 24.0.7.

I’m really surprised how much disk space is used by this dev container, almost 19GB just to start up! Is that normal?

I actually got it working by just re-running the task a few times. But now it’s stuck again, it seems like it’s not fully starting.
