suhlig/concourse-rss-resource repository overview

⁠concourse-rss-resource

Concourse⁠ resource⁠ for RSS feeds. See the example⁠ folder for a pipeline that sends a Slack notification when a new Postgres release is available.

⁠Resource Type Configuration

resource_types:
  - name: rss-resource
    type: registry-image
    source:
      repository: suhlig/concourse-rss-resource
      tag: latest

⁠Source Configuration

• url: Required. The URL of the feed. Anything that can be parsed by Ruby's RSS⁠ gem should be good.

⁠Behavior

⁠check: Extract items from the feed

The resource will fetch the feed specified in url and will version items by their pubDate attribute.

Example

As of writing this README, the PostgreSQL versions feed⁠ has a number of items with a pubDate of "Thu, 27 Oct 2016 00:00:00 +0000" (9.6.1, 9.5.5, 9.4.10, 9.3.15, 9.2.19, 9.1.24, and 9.0.23), of which 9.6.1 is the first and is being returned from check.

⁠in: Fetch an item from the feed

The resource will select the first item of the feed that has the requested pubDate. For each attribute of the that item, it writes the attribute value to a file into the destination directory.

Example

Asked for the version with a pubDate of "Thu, 27 Oct 2016 00:00:00 +0000" on in, the resource will write the following files to the destination directory:

You can then read these files in a task and, for example, construct a Slack notification⁠ saying which new PostgreSQL version is available.

⁠out: Not implemented

There is no output from this resource.

⁠Development

⁠One-time Setup

bundle install

⁠Running the Tests

Tests assume you have a running docker daemon:

bundle exec rake

⁠Docker Image

After a git push to the master branch, if the build was successful, Travis automatically pushes an updated docker image⁠.
