Problem checking healthy state - Docker docs php sample

[Glifaus]

Hi!

I'm following the docker php sample guide but having problems checking the healthy state.

These are the lines in the docs:
healthcheck:
test: ["CMD", "/usr/local/bin/healthcheck.sh", "--su-mysql", "--connect", "--innodb_initialized"]
interval: 10s
timeout: 5s
retries: 5
But, unfortunatly, don't work. db-server is unhealthy and cannot let server to fully load and serve php.

Instead, if i change these lines for others:
healthcheck:
test: ["CMD", "mysqladmin", "ping", "-h", "localhost"]
interval: 10s
timeout: 5s
retries: 3

I can run the demo without problems.

After search i try many options, like in mariadb official docs are information about not using '--su-mysql' or using 'healthcheck.sh' without path, only sh file, but none of them work.

I cannot find why this fail and my attemp works.

Running on macos 13.6.6 with latest docker desktop in macbook air m1.

@Glifaus My containers are showing a healthy status. Maybe there was an error in the documentation at that time and it has since been fixed?

If the issue persists, look at output of docker inspect docker-php-sample-db-1 for the health check logs. There may be some useful information under State --> Health --> Log.
