radicle-native-ci

This is an adapter for the Radicle CI broker, for performing CI runs locally. This means it reads a JSON message from its stdin, and writes two JSON messages to its stdout. Its configured via a configuration file specified in the RADICLE_NATIVE_CI environment variable.

The adapter writes an "admin log" to its standard error output, aimed at the node operator who uses Radicle CI.

The CI run is performed locally, without any isolation. This is not safe and secure, but it's simple, and easy to get working. Do not use this unless you trust the repository and its dependencies.

The repository must contain a file ./radicle/native.yaml that specifies how CI is run for the repository. For example:

shell: |
  cargo test --locked --workspace

This will read .radicle/native.yaml and run the shell commands specified there.

Architecture

See the documentation directory for an architecture document.

Configuration

The adapter requires the RADICLE_NATIVE_CI environment variable to be set to the filename of a configuration file in YAML. For example:

base_url: https://ci.example.org/state
state: /srv/http
log: /home/_rad/native-ci.log

The fields are:

• base_url --- base URL for build logs (mandatory for access from CI broker page)
• state --- required, directory where per-run directories are stored
• log --- required, file where native CI should write the run log

The run log is aimed at the developers of the contents of the repository, instead of the node operator.

Exit codes

The radicle-native-ci executable uses the following exit codes:

• 0 = success, everything went well.
• 1 = failure, the CI run finished, but failed
• 2 = error, the CI run could not be finished

An example of a failure is when the CI run builds software that has a syntax error.

An example of an error is when the adapter configuration file is missing.

Packaging

There is simple, simplistic, rudimentary, personal-use-only packaging for Debian in the debian directory, used by Lars to build packages for his own use.

Running tests

To run the test suite for the CI broker:

cargo test

(The usual way, for a Rust program.)

Also, there is .radicle/native.yaml for testing this with itself in Radicle CI. You may want to run those manually:

yq -r .shell .radicle/native.yaml  | bash -e

(yq is a program like jq, but for YAML files. You can also manually extract the shell field from .radicle/native.yaml.)
