Example Go GitLab CI setup (no root/sudo required)
# See docs/examples
# http://doc.gitlab.com/ce/ci/quick_start/README.html
# http://doc.gitlab.com/ce/ci/yaml/README.html
# GitLab CI template for Go tests. Note this installs
# a new working copy of Go in a non-standard path such
# that sudo/root is not needed for the install stage.
# note that this particular install-environment stage
# is overly verbose in order to debug anything tricky
