at first I am pretty new to Graylog. I am trying to run graylog, mongodb and elasticsearch in a docker via docker-compoe. I want to send my SysLogs via Filebeat. For that, I wanted to install sidecar in the graylog container. I started the docker-compose file via
sudo docker-compose up. After that I tried to run
sudo docker run -t -i graylog/graylog:3.0 dpkg -i ./graylog-sidecar_1.0.0-1_amd64.deb .
The gray log-frontend is running on port 9000. I already created a Collectors Configuration, described in Step-by-Step Guide. But I cant continue with the Administration step, so I assumed, I have to install the sidecar package.
I hope you can help.
