@ -46,6 +46,16 @@ Start a Zabbix proxy container as follows:
Where `some-zabbix-proxy-mysql` is the name you want to assign to your container, `some-mysql-server` is IP or DNS name of MySQL server, `some-user` is user to connect to Zabbix database on MySQL server, `some-password` is the password to connect to MySQL server, `some-hostname` is the hostname, it is Hostname parameter in Zabbix proxy configuration file, `some-zabbix-server` is IP or DNS name of Zabbix server and `tag` is the tag specifying the version you want.

> [!NOTE]
> Zabbix server has possibility to execute `fping` utility to perform ICMP checks. When containers are running in rootless mode or with specific restrictions environment, you may face errors related to fping:
> `fping: Operation not permitted`
> or
> lost all packets to all resources
> in this case add `--cap-add=net_raw` to `docker run` or `podman run` commands.
> Additionally fping executing in non-root environments can require sysctl modification:
> `net.ipv4.ping_group_range=0 1995`
> where 1995 is `zabbix` GID.
