Error response from daemon: driver failed programming external connectivity on endpoint fulcio-fulcio-server-1 (c95568a2f1fd590f020d1b4a2c86d26445dd21c8ade257541198b7fa33dae239): Bind for 0.0.0.0:2112 failed: port is already allocated

The error says that port 2112 is binded, but before running this script, port 2112 is free. But then also it throws an error. I don't understand why it is happening so ?

As far as I know the port is conflicting b/w 2 of the services. rekor-rekor-server-1 as well as fulcio-fulcio-server-1 both trying to use same port 2112.

Solution
On changing the port for fulcio-fulcio-server-1 works i.e. from "${FULCIO_METRICS_PORT:-2112}:2112" to "${FULCIO_METRICS_PORT:-2115}:2112"

This PR has changes related to above.

LGTM on the fix to update the script to set the metrics port for fulcio

I'm sorry it works by exporting the FULCIO_METRICS_PORT. So, closing it.
