Latest Build doesn't work (Based on alpine 3.9)

[gawindx]

Because you are using "alpine-micro" without a tag version in your Dockerfile file, the latest version of this container does not work and you can not connect to the database.

I rebuilt the container, specifying "alpine-micro: 3.8" and the contenter obtained works again.

I noticed that you modfied the Dockerfile by adding the tag "latest" but I think that I misspoke - maybe my English is not good enough (I'm French)

I found that when the image is created since "alpine-micro 3.9/latest", it is not possible to connect to the databases.

On the other hand, if I modify the dockerfile by specifying the "3.8" tag for the "alpine-micro" version, the image is functional again.

So there is a problem of configuration of mariadb with "alpine-micro 3.9" that makes the image unusable but I can not say which one.

If that helps, you'll find below the logs from an "alpine-mariadb" image used with docker-compose Wordpress.

On which platform are you using?
Tested on Mac with 18.09.2

OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system


PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

'/usr/bin/mysqladmin' -u root password 'new-password'
'/usr/bin/mysqladmin' -u root -h 27b478f7b0aa password 'new-password'

Alternatively you can run:
'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd '/usr' ; /usr/bin/mysqld_safe --datadir='/data/db/mysql/'

You can test the MariaDB daemon with mysql-test-run.pl
cd '/usr/mysql-test' ; perl mysql-test-run.pl

I'll do some more test on other platforms

I use it on a Fedore Server, version 27 but up to date.

Docker is in version 18.09 (the last available).

I have not tried starting from a blank base, I only work with my existing base.

I use the image as well on the host as for my different site and service and all via docker-compose.

When I use the alpine-micro 3.9 based image, connection to the database is impossible.
