Install Agent 2

Remove Agent v1 (if present) and install version 2:

wget https://repo.zabbix.com/zabbix/5.4/debian/pool/main/z/zabbix-release/zabbix-release_5.4-1%2Bdebian11_all.deb
dpkg -i zabbix-release_5.4-1+debian11_all.deb
apt update && apt install zabbix-agent2

Configure the agent according to your server setup. And in addition to that un-comment the following line in /etc/zabbix/zabbix_agent2.conf:

### Option: Plugins.Docker.Endpoint
#       Docker API endpoint.
#
# Mandatory: no
# Default: unix:///var/run/docker.sock
Plugins.Docker.Endpoint=unix:///var/run/docker.sock

Connect to your host server and check active certificates:

certbot certificates                                                                                                  
Saving debug log to /var/log/letsencrypt/letsencrypt.log
