policy-agent

The policy-agent is essentially a CircleCI-flavored wrapper library around the Open Policy Agent (OPA), which will allow the users to write the policy documents in CircleCI terminology.

policy-agent is responsible, at its core, for doing the following:

• Integrating with the Go API to evaluate policies.
• Expose custom built-in functions that make policies (i.e., rules) easier to write.

tools setup

We use golangci-lint and task in this repository:

$ brew install go-task/tap/go-task
$ brew install golangci-lint

or

sh -c "$(curl --location https://taskfile.dev/install.sh)" -- -d -b /usr/local/bin
curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b $(go env GOPATH)/bin v1.46.2

See common project tasks with task -l, including:

task lint
task fmt
task test

run lint
