Plugin Site API

This is the backend API for Jenkins Plugin Site frontend. It provides a REST API to allow searching for plugins and retrieving specific plugin information.

Hacking

In order to run the plugin-site-api tests, a service needs to be online which can serve up a DATA_FILE_URL. Assuming docker-compose is installed on the system, the following commands will run the tests properly:

in another terminal: make run
make check

Inspect the Makefile for more targets, such as all which will run tests and build a working container.

Architecture

The REST API calls are powered by Jersey 2.x running inside of Tomcat 8. Plugins are stored and searched via embedded Elasticsearch.

Plugin information sources include:

Jenkins Update Center
- Main source of plugin data
Jenkins Stats
- Installation statistics
Jenkins Wiki
- Scrape wiki content

Elasticsearch mappings are initialized at runtime using a temporary directory that is cleaned up at shutdown. The data is generated via a separate Maven task and stored on an external URL outside of the application. The data file is downloaded from said URL and extracted at boot time. Every 12 hours the application will download the file again and check if it contains new data. If so the application will the reindex the Elasticsearch data using the new data file.

Run Local Plugin Site API

GITHUB_TOKEN=token from https://github.com/settings/tokens
DATA_FILE_URL="https://ci.jenkins.io/job/Infra/job/plugin-site-api/job/generate-data/lastSuccessfulBuild/artifact/plugins.json.gzip" mvn jetty:run

This will launch an embedded Jetty container accessible at http://localhost:8080. DATA_FILE_URL can point to http/https URLS or to local files using the file://${path} syntax.

If GITHUB_APP_ID and GITHUB_APP_PRIVATE_KEY are not set it will try to use a personal access token provided by GITHUB_TOKEN and failing that, your site will be limited to fetching 60 plugin documentation pages per hour.

Run in production mode

You can still use the GITHUB_TOKEN method, but preference is to use github apps (https://github.com/settings/apps) Make sure your pem file is convered from the format github apps gives you to the PKCS#8 format by running

openssl pkcs8 -topk8 -inform PEM -outform PEM -in devpluginsjenkinsio.2020-07-28.private-key.pem -out githubapp.pem -nocrypt

Then configure it by

GITHUB_APP_ID=1234
GITHUB_APP_PRIVATE_KEY="/path/to/pem/file"

Run Docker Plugin Site API

docker build -t jenkinsciinfra/plugin-site-api .
docker run -p 8080:8080 -it -e DATA_FILE_URL="http://url.to/plugins.json.gzip" jenkinsciinfra/plugin-site-api

Rebuild Elasticsearch data

mvn -P generatePluginData

This will generate a new file in target/plugins.json.gzip consisting of plugin information and installation statistics. This file can be now passed as DATA_FILE_URL:

DATA_FILE_URL="file://$(pwd)/target/plugins.json.gzip" mvn jetty:run

REST API Reference

Warning

This API is still in flux as the frontend and backend are still being developed. As such this API is likely to change in the near future.

Unless otherwise indicated, all API calls:

Produce JSON
Do not require authentication
Have no parameters or request body

Possible error codes for all calls:

500

Wait pateiently 10-15 minutes (coffee time!)
Verify that a new container tag has been published here.
Submit a pull request to the jenkins-infra/charts repository updating the backend.image.tag value to the latest container’s tag (here)
Once that is merged the changes will be live
