Infos:
- Used Zammad version: stable
- Used Zammad installation source: (source, package, …)
source: zammad/zammad-docker-compose:master - Operating system: Docker 18.06.1-ce (Ubuntu 18.04 host, docker-compose 1.15.0)
- Browser + version: n/a
I made very minor changes that should allow Zammad to use an external MySQL (MariaDB) database, which I will detail below. I was hoping to submit them for inclusion in the repository if they worked. Essentially, it boils down to setting the database adapter=mysql2 and installing the mysql Gem group rather than postgres during the build process. After that everything happens in docker-compose by dropping postgres-related containers and tweaking the environment.
Expected behavior:
-
zammad-initcontainer should install the database on the MariaDB server
Actual behavior:
-
I get two load errors from the
zammad-initcontainer during init, and the database does not install:LoadError: Error loading the 'mysql2' Active Record adapter. Missing a gem it depends on? libmariadb.so.3: cannot open shared object file: No such file or directory - /usr/local/bundle/gems/mysql2-0.4.10/lib/mysql2/mysql2.sofollowed by:
Caused by: LoadError: libmariadb.so.3: cannot open shared object file: No such file or directory - /usr/local/bundle/gems/mysql2-0.4.10/lib/mysql2/mysql2.so -
The indicated file is present and accessible when I run
ls -lin the container:$ docker-compose exec zammad-init ls -l /usr/local/bundle/gems/mysql2-0.4.10/lib/mysql2/mysql2.so -rwxr-xr-x 1 root root 280856 Feb 18 16:53 /usr/local/bundle/gems/mysql2-0.4.10/lib/mysql2/mysql2.so
Steps to reproduce the behavior:
- Here is the diff of my changes to the zammad containers. I also made changes to the
.envanddocker-compose.*files, but those changes simply configure the options made accessible by the changes below. Building the container must use the--build-arg SQL_ADAPTER=mysql2argument to build for MySQL. Note that I installed thelibmariadb-devandlibmariadbclient-devpackages so that the mysql2 gem would install:
