I’m trying to make a centos version of the opennms docker image following the pattern that was established here https://github.com/opennms-forge/opennms-dockerfiles. The goal is to make a customized version using centos and the foundation-2016 version (tried others too) and later add in customized config files.

When I try to run the ./install –dis I get a SocketException: too many open files

I have attached the Docker files, and supporting files.

Here is the steps I am taking:

1.  

   1.  

      1. kick off the existing database downloaded from the opennms dockerhub
         docker run --name opennms-database -e POSTGRES_PASSWORD=foo -d postgres

1.  

   1.  

      1. build the docker image from the docker file in the current directory
         docker build -t opennms:latest .

1.  

   1.  

      1. run the docker image
         docker run --link=opennms-database:db -e DB_POSTGRES_PASSWORD=foo --name miketest -it -d opennms:latest

1.  

   1.  

      1. open a bash session into the image
         docker exec -it miketest bash

1.  

   1.  

      1. inside the image, manually run the bootstrap.sh (I have the CMD commented out in the docker file)
         /opt/opennms/bin/bootstrap.sh

1.  

   1.  

      1. inside the image, manually run the install command
         /opt/opennms/bin/install -dis
