Env: Access denied for user 'username_here'@'X.X.X.X' error running wp-env start.

[StevenDufresne]

Description

When trying to start a new environment using wp-env, the CLI issues the following error:

mysqlcheck: Got error: 1045: Access denied for user 'username_here'@'172.18.0.5' (using password: YES) when trying to connect

This issue is not specific to working locally using this repository, but exists wherever @wordpress/env is used.

Step-by-step reproduction instructions

1. Destroy your local environment npm run wp-env destroy
2. Re-provision: npm run wp-env start

Expect to see the errors. Should you not see the error, make sure your docker images are updated to the latest.

Quick Debugging

• username_here was implemented in the WordPress docker image fairly recently (docker-library/wordpress@8f5bcc1#diff-7f28a0f62019f2d8b061638e8c3aea207404c1499f1c9241db3216fadd8f4530)
• the wp-config.php in the WordPress container matches the default config in the PR listed above.
• the wp-config.php includes the getenv_docker function that looks for a local env_FILE that does not exist in the WordPress container.
• When looking at the container using the docker desktop app, I see No 'wp-config.php' found in /var/www/html, but 'WORDPRESS_...' variables supplied; copying '/usr/src/wordpress/wp-config-docker.php' (WORDPRESS_DB_NAME)

What I don't know is how wp-env previously defined the DB username and password values. (cc @noahtallen, @noisysocks).

Struggling to find a reference to anything like that. Not sure if the docker container is supposed to work without these specified. If so, it may be an upstream issue.

Also noting that the feature added in the WordPress image was un-betaed yesterday.

docker-library/wordpress@fb920c6

What I don't know is how wp-env previously defined the DB username and password values. (cc @noahtallen, @noisysocks).

IIRC these were omitted because the wordpress image defaulted to user = 'root', password = '' which is what the mysql image also defaults to.

Tried setting explicitely the environoment variables for user and password to "root" and "" in the docker-compose.yml generated by wp-env and for some reason I didn't manage to make it work

[pierlon]

The wordpress image was previously creating the WordPress database if it did not already exist.

Thanks for the hint @pierlon this helped me figure out a potential fix here #29770
