# Most CI providers only clone the branch under test and to a certain depth, so when
# running buf breaking in CI, it is generally preferable to compare against
# the remote repository directly.

# Basic authentication is available, see https://buf.build/docs/inputs#https for more details.

# CI providers will typically have an SSH key installed as part of your setup for both
# public and private repositories. Buf knows how to look for an SSH key at ~/.ssh/id_rsa
# and a known hosts file at ~/.ssh/known_hosts or /etc/ssh/known_hosts without any further
# configuration. We demo this with CircleCI.
