add-pr-body is a custom interceptor for Tekton Triggers that enriches the
payload of an incoming request with the JSON representation of a pull request,
as returned by the GitHub API.
add-pr-body expects the URL to the PR representation to be included in the
incoming JSON as follows:
{
"add-pr-body":
{
"pull-request-url": "https://api.github.com/repos/tektoncd/plumbing/pulls/225"
},
"other-keys": "other=values"
}It returns the original JSON payload untouched, with the addition of the PR:
{
"add-pr-body":
{
"pull-request-url": "https://api.github.com/repos/tektoncd/plumbing/pulls/225",
"pull-request-body":
{
"url": "https://api.github.com/repos/tektoncd/plumbing/pulls/225",

"diff_url": "https://github.com/tektoncd/plumbing/pull/225.diff",
"patch_url": "https://github.com/tektoncd/plumbing/pull/225.patch",
"issue_url": "https://api.github.com/repos/tektoncd/plumbing/issues/225",
"number": 225,
"state": "open",
"locked": false,
"etc": "...",
},
},
"other-keys": "other=values"
}HTTP Headers are left untouched.
A trigger in an event listener:
- name: comment-trigger
interceptors:
- github:
secretRef:
secretName: ci-webhook
secretKey: secret
eventTypes:
- issue_comment
- cel:
filter: >-
body.action == 'created' &&
in('pull_request', body.issue) &&
&& body.issue.state == 'open' &&
body.comment.body.matches('^/test($| [^ ]*$)')
overlays:
- key: add-pr-body.pull-request-url
expression: "body.issue.pull_request.url"The interceptor is installed via ko:
export KO_DOCKER_REPO=gcr.io/tekton-releases/dogfooding
ko apply -P -f tekton/ci/interceptors/add-pr-body/config/
Eventually it should be included in nightly releases and installed from there.
