# This workflow (re)builds and pushes a Docker image containing the
|
|
# protobuf build tools used by the other workflows.
|
|
#
|
|
# When making changes that require updates to the builder image, you
|
|
# should merge the updates first and wait for this workflow to complete,
|
|
# so that the changes will be available for the dependent workflows.
