Base de Dados
* No servidor de database, crie a base de dados.
# mariadb -u root -p
MariaDB> CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
MariaDB> GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@'<IP_or_%>' IDENTIFIED BY '<SENHA>';
MariaDB> GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost IDENTIFIED BY '<SENHA>';
MariaDB> FLUSH PRIVILEGES;
MariaDB> quit;
Nota: O passo abaixo é opcional, após iniciar o container com o apontamento da configuração para o servidor de base de dados sera importado de maneira automática os requerimento abaixo.
Importe os dados iniciais.

Server=192.168.1.102,192.168.254.0/24 <- Adicionar o IP do servidor host e do Zabbix Server Container
ServerActive=192.168.1.102 <- Opcional
Hostname=Hostname do servidor
Nas configurações de Hosts no Zabbix, ter duas configurações:
Servidor
Hostname: Hostname do Servidor
IP: 192.168.1.102:10050
Template: Docker by Zabbix agent2, ICMP Ping, Linux by Zabbix agent
Zabbix Server
Hostname: Zabbix server
IP: 192.168.254.5:10050
Template: Zabbix server health
Reiniciar o serviço
# systemctl restart zabbix-agent2.service
Upgrade Container
Upgrade Container
Depois de atualizar o container avaliar se os logs do SYSLOG que estão apresentando falhas de conexão com o MariaDB, caso sim é necessário atualizar o banco de dados.
