Specify an `int` value in Kubernetes ConfigMap?

Question

Is there a way to specify int values in ConfigMap? When I try to specify a port number I get the following error.

error: error validating \"my-deplo

I was facing a similar issue with setting port number as env variables. I have two services where ServiceB should connect to ServiceA. The error was

/opt/service/config.yml has an error: * Incorrect type of value at: serviceAPort; is of type: String, expected: Integer My config.yml contains something like this - serviceAPort: "${SERVICEA_PORT!'9091'}"

Kubernetes was creating an environment variable SERVICEA_PORT in a format which had Protocol:IP:port. This could not be parsed to an int by ServiceB

I realised this upon using the 'printenv' in ServiceB pod and overrode it with the following config

env:
  - name : SERVICEA_PORT
    value: 9091

Basically, it was a conflict because of env variables created by k8s out of the box.
