Because the ip address is blank, my EC2 instance is not resolving the hostnameip:80. What we saw in Ottawa in the past three weeks was just a prelude. The external IP worked! It connected through to the container without a hitch. My docker container is returning no ip address. And don’t take your eyes off the threat posed by right wing extremism and its funders in Canada and abroad. I am certain that the static IP is assigned to the osticket GCE instance.Ī little extra bg: Earlier, I installed another GCE with a Docker container (Mattermost) with a similar external static IP. I can successfully ping that external address so I know it is connecting to something. I can't find a configuration fix that will make it connect. refused to connect." Connecting to port 8080, I get "This site can’t be reached. Trying to connect from my laptop browser to that external IP, connecting to port 80 I get: "This site can't be reached. When used in production together with HAProxy. I'm wondering if it's possible to access the services provided. HAProxy and Docker containers Docker is a nice tool to handle containers: it allows building and running your apps in a simple and efficient way.
Detect docker ip address container for mac#
Now that I know the docker container is working and I can get to it (at least from within the instance and through that mysterious addr) how is it that GCE external IP addr is supposed to connect through the instance and to that container? Hi, I'm rather new to Docker, and am using the stable release of Docker for Mac on my laptop (mid-2012 MBPr, latest OSX 10.11.6).
Detect docker ip address container full#
The full output of iptables was: Chain PREROUTING (policy ACCEPT)ĭOCKER all - 0.0.0.0/0 0.0.0.0/0 ADDRTYPE match dst-type LOCALĭOCKER all - 0.0.0.0/0 !127.0.0.0/8 ADDRTYPE match dst-type LOCAL
However, I charged forward and within the instance shell (outside the container) I ran Lynx connecting to that IP addr (172.17.0.7:80) and it connected to the osticket website! I'm assuming it connected to the container. After reading up on Docker networking I used this suggested iptables command on the instance (iptables -t nat -L -n) and discovered an IP address (172.17.0.7) whose purpose is a mystery to me: Chain DOCKER (2 references)ĭNAT tcp - 0.0.0.0/0 0.0.0.0/0 tcp dpt:8080 to:172.17.0.7:80
I can connect using Lynx from a bash shell running inside the container (lynx ). I started up the Docker container as normal. My goal is to run a Docker container for osticket on that instance. I set up a Google Compute Engine (GCE) instance with an assigned static IP address.
