This is something that we had to workaround from the official mariadb docker image. That is, we have to make sure that it uses utf. In our examples (see this one) we use the following command:

command: mysqld --character-set-server=utf8 --collation-server=utf8_unicode_ci --init-connect='SET NAMES UTF8;' --innodb-flush-log-at-trx-commit=0

This is the easiest way to fix this that we found (after checking the issues and comments for this image). Maybe there are better/easier ways to fix this? Anyways, this is a good thing to document before the final release.

Please confirm whether the above solution works for you 😃

[Vad1mo]

IMHO
command: mysqld --character-set-server=utf8 --collation-server=utf8_unicode_ci --init-connect='SET NAMES UTF8;' --innodb-flush-log-at-trx-commit=0
is not the right Approach as its a global setting for all databases. If someone happens to have a shared DB, which not such an uncommon case. Portus will dictate the further setup.

However I think the right way is to extend rake db:create to create a DB in the right character set and collation. In this case we don't have to bother with that on the global level. Also the db:status could check if the db is in the right format and complain otherwise.

Example:

default: &default
  adapter: mysql2
  pool: 5
  encoding: utf8mb4
  charset: utf8mb4
  collation: utf8mb4_unicode_ci
  socket: /tmp/mysql.sock

[mssola]

It's bad, yeah, but I already tried your example configuration when we first encountered this and it doesn't work for me. It looks like mariadb has to be called with that command (or to provide an alternative my.cnf), or otherwise the encoding, the charset and the collation will be messed up 😞

PostgreSQL doesn't have this, so using PostgreSQL instead of MariaDB might be a good option when starting as well 😅

[Vesli]

Hey, I've tried to start the mariaDB container with the command you pointed out above, but my portus background continues on restarting and displaying:

/srv/Portus/vendor/bundle/ruby/2.5.0/gems/mysql2-0.4.10/lib/mysql2/client.rb:120:in _query': Mysql2::Error: COLLATION 'utf8_bin' is not valid for CHARACTER SET 'latin1': SELECT COUNT(*) FROM tags` WHERE (name COLLATE utf8_bin = 'latest' AND repository_id = 4) (ActiveRecord::StatementInvalid)
11/04/2018 12:28:21bundler: failed to load command: packaging/suse/portusctl/bin/portusctl (packaging/suse/portusctl/bin/portusctl)

:'(

[Vad1mo]

@Vesli you have to create the db when those setting are set. so execute rake db:drop and rake db:setup

[Vesli]

In the main portus application, I wanted to use both command, but I received this error message:

Do I need to stop Portus first?

--character-set-server=utf8 --collation-server=utf8_unicode_ci --init-connect='SET NAMES UTF8;'
really helps, but it was not an obvious solution for smb like me ;)
Will it be fixed in future?

Moving to the 2.4 project, but I haven't found a proper good solution yet (it's either global or a complete hack...).

Actually, it seems you can change the charset as per https://www.a2hosting.com/kb/developer-corner/mysql/convert-mysql-database-utf-8.

Also, you've got to be joking with rake db:drop.

What is the impact of this issue? In my setup, I can't use such a global configuration.

Documentation already contains information about this (see this). As for a less hackish solution, I'm open to ideas. For now, I haven't found a solution that works and that is more elegant than the one described above... Thank you everybody for the feedback.

What is the impact of this issue? In my setup, I can't use such a global configuration.

The recommended setup is with docker containers, and in that case you can use the following command to start the MariaDB container:

command: mysqld --character-set-server=utf8 --collation-server=utf8_unicode_ci --init-connect='SET NAMES UTF8;' --innodb-flush-log-at-trx-commit=0

This has already been written in our examples. Hope it helps.

@mssola utf8 encoding should never be used with MySQL/MariaDB, because it's broken. utf8mb4 should be used instead.

https://www.eversql.com/mysql-utf8-vs-utf8mb4-whats-the-difference-between-utf8-and-utf8mb4/

I was able to fix this bug by changing the COLLATION of portus tables to utf8_bin since I run my MariaDB with "--character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci" command line
