Install Zabbix Using Docker Compose

This article is for those looking for a detailed and straightforward guide on installing Zabbix using Docker Compose.
Zabbix is a mature and effortless enterprise-class open source monitoring solution for network monitoring and application monitoring of millions of metrics.
💾 You can find the repository used in this guide on GitHub.
NOTEWe’ll use Traefik as our reverse proxy. It’ll handle obtaining cryptographic certificates from Let’s Encrypt for your domain names and route requests to the corresponding services based on those domains.
CAUTIONTo obtain cryptographic certificates, you will need A-type records in the external DNS zone, which point to the IP address of your server where Traefik is installed. If you have created these records recently, you should wait before starting the installation of the services. Full replication of these records between DNS servers can take from a few minutes to 48 hours or even longer in rare cases.
IMPORTANTDocker Engine and Docker Compose must be installed on the server.
For a step-by-step guide on installing Docker Engine on Ubuntu Server, see Install Docker Engine and Docker Compose on Ubuntu Server
IMPORTANTOpenSSH must be installed on the server, and port 22 must be open in order to be able to connect to the server using the SSH protocol.
To install OpenSSH on the server you can use the command:
sudo apt install openssh-server
NOTETo connect to the server from a Windows system, you can use tools like PuTTY or MobaXterm.
NOTEThis guide walks you through connecting to a server with the iTerm2 terminal emulator on macOS.
CAUTIONYou will need to open the following TCP ports for access to the services:
- TCP port 80 - to obtain a free cryptographic certificate through the Let’s Encrypt certification center.
- TCP port 443 - to access the Zabbix web interface.
- TCP port 10051 - to communicate between the Zabbix server and the Zabbix agents for active checks.
We connect to the server on which Zabbix is planned to be installed.
Now it is necessary to create networks for your services.
We create a network for Traefik using the command:
docker network create traefik-network
We create a network for Zabbix using the command:
docker network create zabbix-network
Next, you need to clone the repository that contains the configuration files, which include all the necessary conditions for Zabbix to work.
You can clone the repository using the command:
git clone https://github.com/heyvaldemar/zabbix-traefik-letsencrypt-docker-compose.git
Navigate to the directory with the repository using the command:
cd zabbix-traefik-letsencrypt-docker-compose
Next, you need to change the variables in the .env
file according to your requirements.
IMPORTANTThe
.env
file should be in the same directory aszabbix-traefik-letsencrypt-docker-compose.yml
.
Now let’s start Zabbix with the command:
docker compose -f zabbix-traefik-letsencrypt-docker-compose.yml -p zabbix up -d
To access the Zabbix management panel, go to https://dashboard.zabbix.heyvaldemar.net
from your workstation, where dashboard.zabbix.heyvaldemar.net
is the domain name of my service. Accordingly, you need to specify your domain name that points to the IP address of your server with the installed Traefik service, which will redirect the request to Zabbix.
NOTETou need to specify the domain name of the service, previously defined in the
.env
file.
Now, you can log into the Zabbix dashboard as an administrator.
Use the following default credentials for the Zabbix administrator account:
- Username: Admin
- Password: zabbix
Click on the “Sign in” button.
Welcome to the Zabbix control panel.
Next, to configure the Zabbix server for self-monitoring, we need to define the DNS name of the Zabbix Agent.
Proceed by selecting “Hosts” under the “Data collection” section.
Next, click on the “Zabbix server”.
Within the “Interfaces” section, find the “DNS name” subsection. Enter “zabbix-agent” as the Zabbix Agent service name, referencing the yml
configuration file.
Next, under the “Connect to” section, select “DNS”.
Click on the “Update” button.
After waiting a few minutes, refresh the page. You should then observe that the availability status of the Zabbix Agent has turned green.
To access the Traefik control panel, go to https://traefik.zabbix.heyvaldemar.net
from your workstation, where traefik.zabbix.heyvaldemar.net
is the domain name of my service. Accordingly, you need to specify your domain name that points to the IP address of your server with the installed Traefik.
NOTEYou need to specify the domain name of the service, previously defined in the
.env
file.
Enter the username and password previously set in the .env
file, and click the “OK” button.
Welcome to the Traefik control panel.
