   . There are two approaches to adding the script to the pod: use `oc` commands or
  -edit the deployment configuration.
  +edit the deployment configuration. In both cases the defaultMode for the mounted
  +configMap files must allow execution.  A value of 0755 (493 decimal) is typical.
   
   .. Using `oc` commands:
   +
  
positive.code: $ oc volume dc/ipf-ha-router --add --overwrite \
      --name=config-volume \
      --mount-path=/etc/keepalive \
      --source='{"configMap": { "name": "mycustomcheck"}}'

  .. Editing the *ipf-ha-router* deployment configuration:
  
negative.code: environment variable to point to the mounted script file.
  <2> Add the `spec.container.volumeMounts` field to create the mount point.
  <3> Add a new `spec.volumes` field to mention the ConfigMap.
  <4> This sets execute permission on the files. When read back it will be
  displayed in decimal, 493.
  +
  ... Save the changes and exit the editor. This restarts *ipf-ha-router*.
