Hi

It means that mysql didnt make an image that support ARM, try switching “mysql:5.7” out with “mariadb:latest”

also your WORDPRESS_DB_PASSWORD and MYSQL_PASSWORD needs to be the same, also WORDPRESS_DB_USER and MYSQL_USER

3

Hi now give these pi@raspberrypi:~/exe_docker $ docker-compose up
ERROR: no such image: “mariadb:latest”: invalid reference format

Tank you

Your DB is different, your password is different

7

Can you tell me which line is wrong?

The password/user/database should be the same both places

Please read this tutorial to format your post properly:

This way you can help us to understand your question better.

@terpz fixed your first comment. :+1: so I let you to try to fix the other one. Thank you!

myssql:5.7 did not support ARM. MySQL 8 images has ARM support, but only the oracle variants, not the images with the “debian” suffix.

There is an other MySQL image which is maintained by the MySQL team: mysql/mysql-server

It has ARM support for MySQL 8 but not for MySQL 5.7.

MariaDB is similar to MySQL but not the same. They have a compatibility description: MariaDB versus MySQL - Compatibility - MariaDB Knowledge Base

I don’t know if switching ot MariaDB is better or worse than using MySQL, but that is decision which is not related to Docker.

thanks I already installed it but I can’t access mysql

In the tutorial comes a solution, and is to use the --platform flag:

Are you sharing this output to let us know that you use a compose file with plenty of services where at least one container does not provide an image for linux/arm/v8?

You can actually see in “tags” tab of the Dockerhub repo whether a tag is available as multi-arch images and the architectures they support.
