Installing the grpc python libraries¶
pcocc uses the python-grpcio library, a Python interface for the gRPC framework.
Build the RPMs¶
The required RPMs can be built using pyp2rpm.
You can install this tool on a build node using pip:
pip install --upgrade pyp2rpm
You may have to also upgrade setuptools via pip if it complains.
Generate RPMs for python-protobuf:
install pyp2rpm on a build node with pip
pyp2rpm -t epel7 -b 2 -p 2 protobuf -v 3.6.0 -s
The generated specfile $HOME/rpmbuild/SPECS/python-protobuf.spec
may need to be edited. Under the %files section add if needed:
%{python2_sitelib}/%{pypi_name}-%{version}-py%{python2_version}-nspkg.pth
Build the RPMs:
rpmbuild -ba $HOME/rpmbuild/SPECS/python-protobuf.spec
Generate and build RPMs for grpcio and grpcio_tools:
pyp2rpm -t epel7 -b 2 -p 2 grpcio -v 1.13.0 -s
rpmbuild -ba $HOME/rpmbuild/SPECS/python-grpcio.spec
pyp2rpm -t epel7 -b 2 -p 2 grpcio_tools -v 1.13.0 -s
rpmbuild -ba $HOME/rpmbuild/SPECS/python-grpcio_tools.spec
Put the resulting packages in your local repositories and install them on your front-end and compute nodes or wait for pcocc to pull them as a dependency.
