How to run same docker images twice

Question

I am using this docker command for running graylog2.

docker run -t -p 9000:9000 -p 12201:12201 graylog2/allinone

I want to run another graylog2 in same server and I run new command with different port numbers as

docker run -t -p 9001:9000 -p 12202:12201 graylog2/allinone

It's not working because of port conflict.

I am getting this error

Caused by: java.net.ConnectException: Connection refused: /127.0.0.1:12900

Answer 1

Use docker run --name="new_name" -d imagename

Use different port for mapping from container to host or use host networking.
