What is preventing external connections to TCP port 1111 to connect to Virtuoso running within a Docker container?
Short story. I am unable to connect to port 1112 (which is mapped to 1111 in the docker container construction command) from the external network interface. I am able to connect to port 1111 from inside the docker container on both localhost and external network interfaces. >From the computer on which the docker container is running I am able to connect to port 1112 (which is mapped to 1111 in the docker container construction command) if I connect via localhost. $ time nc -zv localhost 1112; Ncat: Version 7.50 ( https://nmap.org/ncat ) Ncat: Connected to ::1:1112. Long story. The docker container start script has instructions to map host TCP port 1112 to TCP docker container port 1111. I have installed Virtuoso 7.2.6-dev on a CentOS 7 in a docker image. In the docker container generation command that spawns a new docker container from the above image, I have exposed TCP port 8891 (of the host) to connect to TCP 8890 (of the container), and TCP port 1112 (of the host) to connect forward to TCP port 1111 (of the container). >From the docker container hosting computer, I can successfully connect to port 8891 but I cannot connect to port 1112. See below. $ time nc -zv ${HOSTNAME} 8891; Ncat: Version 7.50 ( https://nmap.org/ncat ) Ncat: Connected to 10.74.218.8:8891. Ncat: 0 bytes sent, 0 bytes received in 0.02 seconds. $ time nc -zv ${HOSTNAME} 1112; Ncat: Version 7.50 ( https://nmap.org/ncat ) Ncat: No route to host. >From inside the container, I can connect via the "external" network interface, see below.
