romp

Run on multiple platforms

I use pip-tools but also want to keep my compiled requirements for multiple platforms. Instead of sharing directories between machines or otherwise shuttling files around I chose to create romp which will let me submit arbitrary work to Azure Pipelines to get access to multiple platforms. Personally, I will use this primarily behind boots.

Below is an example usage. It will run a single job under Linux with 64-bit CPython 3.6. The job will execute echo red > blue.txt and will collect *.txt from the job and save it locally to artifacts.tar.gz.

$ venv/bin/romp --platform linux --interpreter cpython --version 3.6 --architecture x86_64 --command 'echo red > blue.txt' --artifact-paths '*.txt' --artifact artifacts.tar.gz

Handling artifact

Since romp leverages Azure Pipelines to get access to all the platforms, server-side setup is required. You will need an Azure account and to create a pipeline (build) within that account using a romp repository (official or your own fork). Configure the pipeline to use deployed_ci/azure/azure-pipelines-lock.yml. It is configured such that commits do not trigger builds. romp’s own CI and testing is driven by azure-pipelines.yml in the project root but this file can be ignored for regular use. Once the pipeline is setup you will need to create a Personal Access Token (PAT) to use for authentication when running romp. The PAT will need the build read and execute scope enabled.

For local setup, the command line options can be set by environment variables. For many options this will not make sense but for a few it will. Specifically consider the follow options which will often be consistent for all calls.
