Is it possible to deploy servers for OMH-dsu-ri and Shimmer on the same machine?

[Divya Rathor]

Hello OMH Dev Group,

I'm exploring the possibility of deploying the [Authorization and Resource Servers] for omh-dsu-ri and the Resource Server for shimmer on the same VM, using mHealth's Docker images. As expected, in doing so, I have a conflict on port 8083.

Error message:

 

Creating shimmer_console_1         ... error

ERROR: for console  Cannot start service console: b'driver failed programming external connectivity on endpoint shimmer_console_1 (c21e5cc7c3b9055c8d229c68053da2f5afbc91c70472691292dbc7455927ba99): Bind for 0.0.0.0:8083 failed: port is already allocated'

ERROR: Encountered errors while bringing up the project.

To avoid this, even though I explicitly set port 8085 for shimmer-console (instead of 8083) in the 'docker-compose-build.yml' and 'docker-compose.yml' files, and skip installing the Console for shimmer, the Jetty still starts on port 8083 at the end of installation. There are no errors thrown at this time. But, the Resource Server of DSU which had already been published at port 8083 with the installation of omh-dsu-ri becomes dysfunctional.

Could you suggest., if there is a way to deploy both omh-dsu-ri and Shimmer on the same VM, or is it recommended to have them operating on two different VMs? If latter, how do they communicate with each other?

I've been waiting for help on this problem for a long time. Therefore, I'll appreciate your help and support. Thank you!

Best,

Divya

Hi Divya, 

They can be deployed on the same machine. If any of their ports clash, the port numbers should be relatively easy to change.

Maybe someone else can chime in?

Hi David,

Thank you for confirming that the deployment of all servers is possible on a single machine! I thought as much, and had tried by changing the port for Shimmer console in configuration files to be different from 8083. But, it did not help, as it appears that it is hard-coded somewhere internally. If someone can point out what else to change in the code, I'll really appreciate it. Thanks much!

Best,

Divya
