Port opening OPCUA Server

[ansirigi]

Hello Stefan,
we would like to deploy our own snap package on to the ctrx.docker-docker running on a seperate port (to be specific 51210).
We could deploy it and access it only locally but could not connect from other devices connected in the same network. Nmap shows the port is filtered. FYI, we are Rexroth partnes and not using container engine UI licensed but  only from command line. We have also disabled firewall app on ctrlx. It would be grateful if you could guide us on opening of port. We tried everything like iptables and ufw etc. to forcefully open the port from OS side but nothing helped us. Please do not hesitate to contact for the further information.

Following are details of cntrlx device.

- UBUNTU Core 20 OS

Hardware Version
    cx_m4_a

    AD1

Following is the nmap output from another ubuntu device connetced in the same network. 192.168.1.1 is the ip of ctrlx.

I'm sorry, I don't quite understand your question. If you want to deploy Docker Containers on the ctrlX CORE you would need to install the ctrlX Container Engine App. The app represents the interface between the resources of the ctrlX CORE and the running containers. Using a snap template, a Docker image application for the ctrlX CORE can be created from a Docker image and the corresponding Docker configuration files.

If you want to learn more about how to use the Container Engine App you can look at the manual and at a how to video:

• Container Engine App, Use of Docker® Images on ctrlX CORE, Application Manual
• How-to - Depoy Docker Image to Container Engine App

I would really recommend to watch the How-to video I mentioned. Please take a look especially at minute 10:00 of the How-to video. Our expert shows here how to specify ports to open and forward on the container. 

In addition, I would recommend to look at the Docker Compose File Reference.

Additional information: in the app developer guideline is list of ports, which are already in use and therefore can't be used by your app.
