Fixed by upgrading Magento from 2.4.7 to 2.4.8.

In my case I needed Magento 2.4.7 on macOS via docker-magento. The following resolved the problem for me.

The first two steps of the Manual Setup worked fine:

Sites % mkdir m247
Sites % cd m247
m247 % curl -s https://raw.githubusercontent.com/markshust/docker-magento/master/lib/template | bash
m247 % bin/download community 2.4.8

Then, the Setup step gave an error:

m247 % bin/setup m247.test
...

  Current version of RDBMS is not supported. Used Version: 11.4.8-MariaDB-ubu  
  2404. Supported versions: MySQL-8, MySQL-5.7, MariaDB-(10.2-10.6)            

I changed the MariaDB version in compose.yaml

m247 % vim compose.yaml

  db:
    ## image: mariadb:11.4
    image: mariadb:10.6

I re-ran the Setup command:

m247 % bin/setup m247.test
...
container for service "db" is unhealthy

I increased the interval, timeout, and retries in compose.healthcheck.yaml for the db:

m247 % vim compose.healthcheck.yaml

  db:
    healthcheck:
      test: "mysqladmin ping -h localhost -u root -pmagento || mariadb-admin ping -h localhost -u root -pmagento"
      <<: *healthcheck-defaults
      interval: 10s
      timeout: 300s
      retries: 100

However, it still gave the same error:

container for service "db" is unhealthy

Upon inspecting the docker logs this error showed up:

m247 % docker logs m247-db-1
...
2025-08-30 17:21:35 0 [ERROR] Unknown/unsupported storage engine: InnoDB
2025-08-30 17:21:35 0 [ERROR] Aborting

Gemini suggested I delete the Docker volume for the MariaDB container and repeat the step from the Manual Setup:

m247 % docker stop m247-db-1
m247 % docker rm m247-db-1
m247 % docker volume rm m247_dbdata
m247 % bin/setup m247.test

Afterwards, Magento installed successfully:

...
[Progress: 1457 / 1457]
[SUCCESS]: Magento installation complete.
[SUCCESS]: Magento Admin URI: /admin
...

For installing Magento 2.4.8 on macOS via docker-magento the only thing I needed to change was the x-healthcheck-defaults in compose.healthcheck.yaml from 5s/5s/30 to 10s/300s/100 as follows:

Before:

x-healthcheck-defaults: &healthcheck-defaults
  interval: 5s
  timeout: 5s
  retries: 30

After:

x-healthcheck-defaults: &healthcheck-defaults
  interval: 10s
  timeout: 300s
  retries: 100
