This is a simple image for getting zabbix up and running. Nothing special.
To get the database setup, you might need to go into the container after it have started and run;
psql -h db -U postgres postgres < /usr/share/doc/zabbix-server-pgsql-2.4.7/postgresql/schema.sql
psql -h db -U postgres postgres < /usr/share/doc/zabbix-server-pgsql-2.4.7/postgresql/images.sql
psql -h db -U postgres postgres < /usr/share/doc/zabbix-server-pgsql-2.4.7/postgresql/data.sql
As you can see, database needs to be linked as db, and we are using postgres.
