Docker image for the Babylon chain in cosmos
If you're building Docker images on a Macbook using Docker Desktop, by default, it builds images for the linux/arm64/v8 architecture since Docker Desktop runs on an Apple M1 chip, which is based on ARM architecture. To build Docker images for the linux/amd64/v3 architecture on your Macbook, you have a few options:
Use Docker Buildx: Docker Buildx is a Docker CLI plugin that provides extended build capabilities with BuildKit. It supports building images for multiple platforms, including linux/amd64. Here's how you can use it:
bash Copy code
export DOCKER_CLI_EXPERIMENTAL=enabled
docker buildx create --use --name mybuilder
docker buildx build --platform linux/amd64 -t your_image_name:your_version . This will build the image for the linux/amd64/v3 architecture.
Use Docker Desktop with Rosetta 2: If you're using an Apple M1 chip, you can run Docker Desktop using Rosetta 2 translation, which allows running Intel-based (x86_64) applications on ARM-based Macs. This way, Docker Desktop will run in the x86_64 emulation mode, and you can build images for the linux/amd64/v3 architecture.
To enable Rosetta 2 for Docker Desktop:
Right-click on Docker Desktop in the Applications folder. Select "Get Info." Check the box next to "Open using Rosetta." After enabling Rosetta 2, Docker Desktop will run in the x86_64 emulation mode, allowing you to build images for the linux/amd64/v3 architecture.
Use a Remote Docker Host: You can set up a remote Docker host running on a Linux machine and build your images there. This way, you can ensure that the images are built for the linux/amd64/v3 architecture.
Choose the option that best fits your requirements and environment.
