reqProc is the Shippable agent that needs to run on the node for the node to
accept and execute builds. reqProc always runs as a Docker container and is responsible for following:
- periodically pinging Shippable API with health checks
- listening for and accepting new builds
- validating and unpacking build data and secrets
- generating build steps
- updating the build status
It is one of the three components that are installed on the host when users initialize the host to act as a build node on Shippable. The other two components that are installed upon node initialization are reqKick and reqExec.
For each supported architecture and OS, a different Docker image is built. All
the Dockerfiles are present in image/ folder in the project root.
Any merged change in the project triggers Shippable assembly lines to
re-package all necessary requirements and dependencies and push the updated
Docker images with master tag.
Once all the jobs are completed, the images can be tested by initializing nodes manually in the test environment or running automated tests using bvt.
Supported platforms:

reqProc images for each supported platform are updated with every Shippable
release. The list of all Shippable releases can be found here.
