When I was testing Docker’s initial tutorial when you download for the first time I got the error:
The requested image's platform (linux/arm64) does not match the detected host platform (linux/amd64) and nospecific platform was requested.
It sucks because I got a new MacBook Pro M1 and I did not know about these issues with arm64 chips and images. Trying to play with the tutorial while having great coffee from Latin America I got stuck when trying to run the MySQL image in my compose file.
Searching around I found two options to resolve this. See below:
Option 1: Add the flag –platform linux/arm64
This will tell your MacOS M1 what platform to use. Brief example:
docker run -d \ --platform linux/amd64 \ --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
Option 2: Use MariaDB instead of MySQL
As of this post MariaDB offers official support for ARM64 architecture. Use this docker command instead as an example:
docker run -d \ -v todo-mysql-data:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=secret \ -e MYSQL_DATABASE=todos \ mariadb:10.5
