Docker Graylog (ELK & MongoDB) Installation Fails in Centos 8 Server

Graylog Central (peer support)

Dear all,

My name is Dimitrios and I try to install Graylog , Elasticsearch and MongoDB from the official manual page in CentOS 8 using Docker (https://docs.graylog.org/en/3.3/pages/installation/docker.html#persisting-data). I have the docker-compose.yml like the attached page but I face the below problem.

Has anybody face the problem? I am a newbie and I really want to understand what is the problem.

Regards,

Dimitrios

I thought it was Graylog the problem. The problem is VM’s OS. CentOS 8 does not support interconnection between containers.

Hi Dimitrios,

I use podman-compose on CentOS 8 and graylog 3 works ok.

Here is a docker-compose.yml file that works, you just need to change the values of the GRAYLOG environment variables and ensure firewalld has all ports open ( firewall-cmd --permanent --add-port=9000/tcp --add-port=1761/tcp --add-port=5044/tcp --add-port=9100/tcp --add-port=1514/tcp --add-port=1514/udp --add-port=12201/tcp --add-port=12201/udp && firewall-cmd --reload ).

Hope that helps.

Thank you for your response! Just a quick question: Is it possible to install logstash with docker and configure it properly? Have you ever tried it?

Sorry I have never tried it. I’m not sure what you would need to do if using it with graylog but the logstash docker image can be found at https://www.docker.elastic.co/r/logstash
