# OpenShift Flowdock Notifier
**Sends notifications to Flowdock about events happening in your OpenShift cluster.**
This [Go](http://golang.org/) application is an [OpenShift](http://www.openshift.org/) client that listen to events in the cluster, and post notifications to the inbox of your [Flowdock](https://flowdock.com/) flows.
## How It Works
This application can be deployed on OpenShift - or anywhere else, but I guess you will want to run it in your OpenShift cluster.
It should run with a [ServiceAccount](https://docs.openshift.org/latest/architecture/core_concepts/projects_and_users.html#users) that has enough rights to watch the events you want to forward to Flowdock. You have 2 solutions:
* use the [provided template](openshift-template-deploy-only.yml) that creates a specific ServiceAccount (`flowdock-notifier`) with the right role (`view`) - this is good if you want notifications for a single project, or for just a few projects (in this case you will need to add more rights to the ServiceAccount)
* create a ServiceAccount with the `cluster-reader` role - this solution should be used if you want notifications for the whole cluster, but it requires admin rights to setup.
Based on a configuration file (or environment variables), it will watch pre-defined types of resources, and use the [Flowdock API](https://www.flowdock.com/api) to send notifications to the [Team Inbox](https://www.flowdock.com/help/team_inbox) of one (or more) [flows](https://www.flowdock.com/help/flows).
It uses the [Flow Token](https://www.flowdock.com/api/authentication#source-token) to send mail-like messages to the team inbox of a flow using the [Team Inbox Push API](https://www.flowdock.com/api/team-inbox). You can find the flows tokens in your [account page](https://www.flowdock.com/account/tokens).
### Supported events
For the moment, the following events are supported:
* [Builds](https://docs.openshift.org/latest/architecture/core_concepts/builds_and_image_streams.html#builds) events: when a new build has been started, has successfully completed, has failed, has been cancelled, ...
More events are in the roadmap ;-)
You can either use a few environment variables for a basic and simple configuration - it is the fastest to setup, but more limited - or you can use a configuration file, but it requires more work to setup.
#### Environment variables based configuration
This way of configuring the application is recommanded if you want to send the notifications of a single project to a single flow.
The following environment variables are supported:
* `NOTIFIERS_DEFAULT_TOKEN` to configure the [Flow Token](https://www.flowdock.com/api/authentication#source-token) for the flow that will receive the notifications - Go to your [account page](https://www.flowdock.com/account/tokens) to retrieve the token.
* `NOTIFIERS_DEFAULT_SOURCE` if you want to overwrite the name of the source in the notification - defaults to `OpenShift`.
* `NOTIFIERS_DEFAULT_FROM_NAME` if you want to overwrite the name of the sender in the notification - defaults to `OpenShift`.
* `NOTIFIERS_DEFAULT_FROM_ADDRESS` if you want to overwrite the address of the sender in the notification - defaults to `firstname.lastname@example.org` for successful builds or `email@example.com` for failed builds, or `firstname.lastname@example.org` for all other events. Note that this address is used to display an avatar from the [Gravatar service](https://gravatar.com/) - see the [Flowdock Team Inbox API](https://www.flowdock.com/api/team-inbox) for more informations.
* `ENABLE_DEFAULT_BUILDS_WATCHER` to enable the default builds watcher, that will
## Running on OpenShift
If you want to deploy this application on an OpenShift cluster, you need to:
* create a new application from the provided [openshift-template-deploy-only.yml](openshift-template-deploy-only.yml) template, and overwrite some parameters:
oc new-app -f openshift-template-deploy-only.yml -p FLOW_TOKEN=xxx
Of course, replace `xxx` by the value of your [GitHub Access Token](https://help.github.com/articles/creating-an-access-token-for-command-line-use/). To create such a token, go to your [GitHub Tokens Settings](https://github.com/settings/tokens) page, and create a new token with the `admin:repo_hook` scope.
* optional - if you want to get notifications from more than 1 project:
* either add the `view` role to the `flowdock-notifier` ServiceAccount in a different project (you will need to be admin in the other project):
oc policy add-role-to-user view system:serviceaccount:$(oc project -q):flowdock-notifier -n PROJECT_NAME
The `$(oc project -q)` is used to get the name of the current project, in which the `flowdock-notifier` ServiceAccount has been created. Don't forget to replace `PROJECT_NAME` with the name of the other project. This can be repeated for any number of projects.
* or give the `cluster-reader` role to the `flowdock-notifier` ServiceAccount (you will need to be cluster admin for that):
oadm policy add-cluster-role-to-user cluster-reader system:serviceaccount:$(oc project -q):flowdock-notifier
The `$(oc project -q)` is used to get the name of the current project, in which the `flowdock-notifier` ServiceAccount has been created.
You can use either of the following templates:
* [openshift-template-deploy-only.yml](openshift-template-deploy-only.yml) to just deploy from an existing Docker image - by default [vbehar/openshift-flowdock-notifier](https://hub.docker.com/r/vbehar/openshift-flowdock-notifier/)
* [openshift-template-full.yml](openshift-template-full.yml) to build from sources (by default the [vbehar/openshift-flowdock-notifier](https://github.com/vbehar/openshift-flowdock-notifier) github repository) and then deploy
## Running locally
If you want to run it on your laptop:
* Install [Go](http://golang.org/) (tested with 1.6) and [setup your GOPATH](https://golang.org/doc/code.html)
* clone the sources in your `GOPATH`
git clone https://github.com/vbehar/openshift-flowdock-notifier.git $GOPATH/src/github.com/vbehar/openshift-flowdock-notifier
* install [godep](https://github.com/tools/godep) (to use the vendored dependencies)
go get github.com/tools/godep
* build the binary with godep:
godep go build
* configure the application, either with a `config.yml` file, or with some environment variables (see the configuration section)
* start the application in verbose mode
