install_ca_certs.sh

#! /bin/bash
#
# install_ca_certs.sh -- copy the specified CA certificates into this source so that they can be used
#                        to build the software via docker.
#
# usage: install_ca_certs.sh CA_CERT_FILE...
#
#   where CA_CERT_FILE is a file path to a CA certificate to install
#
# This script helps address the problem with docker-based builds when run within a firewall that
# replaces external site certificates with ones signed by a non-standard CA, causing the retrieval
# of software dependencies to fail.  This script is used by oar-docker's localbuild script to receive 
# extra CA certificates that addresses such failures.  Because localdeploy makes no assumptions about 
# how this source code repository builds using docker, this script encapsulates that knowledge on 
# behalf of localbuild.
#
# Note: if this repository does not require/support use of non-standard CA certificates, remove (or
# rename) this script.
