# This script uses the Atlas proxy project's own evergreen launch script
# to build and launch an Atlas proxy for testing.  It works directly from
# their master branch, so may fail if they break something.
#
# There is no corresponding 'shutdown' script; the Atlas proxy project
# relies on Evergreen to terminate processes and clean up when tasks end,
# so we do the same.
#
# The URI is harded coded as:
# mongodb://user:pencil@host5.local.10gen.cc:9900/admin?replicaSet=benchmark
#
# Connections requires SSL and the CA file is 'main/ca.pem' in the atlasproxy repo.
#
# If this fails, check the 'main/test.sh' file in the atlasproxy repo for
# possible changes.
#
# Installation of Go dependencies appears to require a newer git.  1.7 on
# rhel62 failed, but 2.0 on ubuntu1604 worked.  The atlasproxy project
# itself tests on rhel70.
#
# This script expects the following environment variables:
#
# DRIVERS_TOOLS (required) - absolute path to the checked out
# driver-evergreen-tools repository
#
# MONGODB_VERSION - version of MongoDB to download and use. For Atlas
# Proxy, must be "3.4" or "latest".  Defaults to "3.4".

set -o xtrace   # Write all commands first to stderr
set -o errexit  # Exit the script with error if any of the commands fail
