Running multiple instances on same host with different ports?

[benjamin604]

Hello, not really an issue, but more of a question. I've got a single instance running on 5800, but would like to run another 3-5 instances from the same VM host. I tried just iterating all the ports, but while the docker starts, it doesn't work.

if I curl http://host-ip:5801, I get "Empty reply from server"

Anyone running multiple instances that could point me in the right direction?

Thanks, Ben

How did you created your containers ? To have multiple instances, you should map port 5800 to a different port with the -p argument of the docker run command.

For example, the first instance could use -p 5801:5800, the second -p 5802:5800, etc.

Ah, I was running the following:

sudo docker run -d --name=firefox5800 -p 5800:5800 -v /docker/appdata/firefox5800:/config:rw --shm-size 2g jlesage/firefox sudo docker run -d --name=firefox5801 -p 5801:5801 -v /docker/appdata/firefox5801:/config:rw --shm-size 2g jlesage/firefox sudo docker run -d --name=firefox5801 -p 5802:5802 -v /docker/appdata/firefox5802:/config:rw --shm-size 2g jlesage/firefox

I'll try your suggestion now, thank you!
