[ZBX-18420] Docker based Zabbix-Agent: Cannot ping/access Docker Daemon from within docker Created: 2020 Sep 27  Updated: 2020 Sep 28  Resolved: 2020 Sep 27

Status: Closed
Project: ZABBIX BUGS AND ISSUES
Component/s: Agent (G)
Affects Version/s: 5.0.3
Fix Version/s: None

Type: Problem report Priority: Trivial

Original Estimate: Not Specified
Environment:

CentOS 7 Docker host
Docker run Zabbix Agent 5.0.3
Docker run Zabbix Server 5.0.3


 Description   

Steps to reproduce:

  1. Install Docker based Zabbix Agent
  2. Connect over Docker network to agent from Zabbix Server
  3. Configure Docker Application Template
  4. Fails to connect to Docker

I am stumped as to what I need to do in order to give the Zabbix Agent proper access to the Docker Daemon it is running on. On the host outside the container I can "ping docker-host" just fine but within the zabbix-agent container it fails...

Result:


Expected:
Connect to Docker Daemon and be able to see stats from it within Zabbix Server.

Docker has different type of network options: https://docs.docker.com/network/, connectivity issue is not related to the Zabbix.

May be you have bridge network, so you need to monitor address of the container behind bridge or expose correctly ports for the Agent container.

Please note - to monitor Docker you need to mount volume with Docker socket path to the Agent container. Also you need to use Agent 2 (GO written).
