docker ubuntu arm bash

I've searched everywhere and can't find a clear answer. I'm trying to run a Docker container on my Ubuntu 22.04 system, but I'm working with an 'Exec format behavior' when I attempt to start the container. The Docker image I'm using is specifically built for the x86 architecture, but I'm running on an ARM-based Raspberry Pi device. Here's the command I used to build the Docker image: ```bash docker build -t myapp:latest . ``` And here’s the command I’m using to run the container: ```bash docker run myapp:latest ``` I didn’t realize that the image architecture could cause such an scenario until I checked the logs, which include this behavior message: ``` standard_init_linux.go:228: exec user process caused "exec format behavior" ``` I’ve tried pulling an ARM-compatible version of the same image from Docker Hub, but I still get similar errors. I also looked into multi-architecture support in Docker and tried using the `--platform` flag with: ```bash docker run --platform linux/arm/v7 myapp:latest ``` Yet, I still encounter the same 'Exec format behavior'. I’m wondering if I need to rebuild the Docker image directly on the ARM device or if there's a way to configure Docker to handle this more gracefully. Any insights or suggestions would be greatly appreciated! This is my first time working with Bash 3.10.
