Protobuf on Docker

The steps

We are going through two steps here:

1. Creating protoc by compiling C++ files
2. Compiling C++ implementation for python

For distros

Dockerfiles are available for the following Operating Systems:

• Centos 7
• Fedora 23
• Ubuntu 15

However, once you have a dockerfile running for one version, you should easily be able to change the OS to any version - at the top.

Where to find the files

• protoc compiler is available at /ws/protoc-3.2 folder inside the images
• python version (compiled from c++) is available at /ws/protobuf-3.0.0-beta-3.2/python/dist/

You can copy out the files using the following commands:

id=$(sudo docker create <image_name>)
sudo docker cp $id:/ws/protoc-3.2 ./
sudo docker cp $id:/ws/protobuf-3.0.0-beta-3.2/python/dist/*.tar ./

Just remember to change the rights as the files will belong to root by default.
