What is the process for utilizing docker's Rosetta 2 x86_64 emulation while creating a docker image on an arm64 system architecture?

edit

To utilize Docker's Rosetta 2 x86_64 emulation while creating a docker image on an arm64 system architecture, follow these steps:

1. Install Docker Desktop for Mac on your arm64 system architecture.

2. Open Terminal on your Mac and run the following command:

   arch -x86_64 /bin/bash
   

   This will switch the Terminal to the x86_64 architecture.

3. In the x86_64 Terminal, create a new Dockerfile for your image using the "FROM" command to specify the base image that you want to use. For example:

   FROM node:14-alpine
   

4. Build your Docker image as usual using the "docker build" command. For example:

   docker build -t my-image .
   

   This will build your image using the x86_64 architecture and emulated using Rosetta 2.

5. After the build is complete, switch back to the arm64 architecture by running the following command:

   arch -arm64 /bin/bash
   

6. Run your Docker image using the "docker run" command. For example:

   docker run my-image
   

   This will run your image on the arm64 architecture using the emulation provided by Rosetta 2.

Note: This process is specific to Mac environments running on arm64 architecture. Other operating systems or architectures may have different steps or requirements for utilizing Rosetta 2.
