Hi

At the wordpress installer, what do you type in as a database hostname?

also, in your wordpress “networks” attr, you typed in:

networks:
local:

should be:

networks:
- local

also, try and rename/alias your mariadb container to “mysql”, or add the env:

WORDPRESS_DB_HOST: mariadb

to your wordpress container

If I change “local:” to “- local” : ERROR: yaml.parser.ParserError: while parsing a block collection
in “./docker-compose.yml”, line 11, column 7

With “WORDPRESS_DB_HOST: mariadb” problem resolved.
