### Docker
Provided with the opensource [image](https://www.zabbix.com/container_images), the container can be setup easily. The critical issue is to expose the zabbix' service.

<table>
<thead>
<tr><th colspan=2>Expose Port</th></tr>
</thead>
<tbody>
<tr>
<td>Zabbix-server </td><td>10051</td>
</tr>
<tr>
<td>Zabbix-agent </td><td>10050</td>
</tr>
<tr>
<td>Zabbix-frontend</td><td>80</td>
</tr>
</tbody>
</table>

In order to expose Docker's container, we used the ipvlan network appoach.

#docker run -it --name zabbix ... zabbix/zabbix-server
docker network create --name ipvlan
docker network connect ipvlan zabbix

## Known Issues

#### 1. issue with permission (service not running): [reference](https://www.zabbix.com/forum/zabbix-troubleshooting-and-problems/389428-failed-to-start-zabbix-server-for-1st-time)

Solution:</br>
&emsp;&emsp;give permission through <font color=gray> *ausearch*</font>

# ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver
# semodule -X 300 -i my-zabbixserver.pp
....
# ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver
# semodule -i my-zabbixserver.pp
....
# systemctl restart zabbix-server.service
# systemctl status zabbix-server.service
....

&emsp;&emsp;OR

&emsp;&emsp;[Turn off SELinux](https://www.opencli.com/linux/disable-selinux)

#### 2. Regex Preprocessing : can only match up to 9 results in each step:

Solution:

&emsp;&emsp;split the string into multiple segments, and perform regex parsing separately.

#### 3. ssh agent's issue with libssh:
