Part 7: Multi-Container apps: Cannot run MySQL container in arm64 arquitecture

Hi, I’m trying to run the command docker run -d \ --network todo-app --network-alias mysql \ -v todo-mysql-data:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=secret \ -e MYSQL_DATABASE=todos \ mysql:5.7

But it fails with: docker: no matching manifest for linux/arm64/v8 in the manifest list entries.

I am using a MacBook Pro M1, Big Sur 11.3.

I understand the issue is with the MySQL image, not supporting the arm64 arquitecture, but it would be good for the tutorial to have at least a workaround for people using arm64 machines. Thank you

I managed to solve it by simply passing the flag --platform linux/amd64.

Would be nice though if this info was in the tutorial

Hi all, for me the simplest solution was to replace Mysql with mariadb, which is also available for ARM64. Since mariadb is an API-preserving fork of Mysql which even can cope with MYSQL environment variables, no changes have to be made to the App code. Merely, “mysql” has to be replaced by “mariadb” in the docker run commands for the database container docker run -d \ --network todo-app --network-alias mariadb \ -v todo-mariadb-data:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=secret \ -e MYSQL_DATABASE=todos \ mariadb and docker run -dp 3000:3000 \ -w /app -v "$(pwd):/app" \ --network todo-app \ -e MYSQL_HOST=mariadb \ -e MYSQL_USER=root \ -e MYSQL_PASSWORD=secret \ -e MYSQL_DB=todos \ node:12-alpine \ sh -c "yarn install && yarn run dev" for the todo-app container. The same database commands (e.g. select * from todo_items;) can be used, just don’t forget to connect beforehand to mariadb instead of mysql, e.g. via docker exec -it <mariadb-container-id> mariadb -p todos.

Hope, this is helpful.
