Slackduty

Slackduty synchronize Slack usergroup based on PagerDuty users, teams, services and schedules

NOTE: THis is not for production usage yet. It is under PoC.

Design

Slackduty fetches the users based on the PagerDuty resources.
You can also specify the Slack user and users you don't want to include.

How to run

You can test in your local environment before deploying.
First clone this repository to your local environment.

$ git clone https://github.com/KeisukeYamashita/slackduty

And then copy the config YAML file to the path where Slackduty looks for and edit the file.

$ mkdir ~/.slackduty
$ cp ./config/example.yml ~/.slackduty/config.yml

Make sure that you configure the enviroment varibles.

$ cp .envrc.sample .envrc

# fill in the API keys
$ vim .envrc 
$ direnv allow

Edit the file and run slackduty.

$ go run main.go

How to deploy

There are various ways to deploy the Slackduty.

1. Single process

Deploy as single process

You can just run Slackduty as a process by the way you did as running in your environment.

$ go run main.go

2. Kuberenetes CronJob

Deploy as Kubernetes CronJob

Dockerize this application and save to your container registry.
Here, I used Google Container Registry.

$ docker build . -t gcr.io/my-project/slackduty
$ docker push gcr.io/my-project/slackduty

And then create a edit the Cronjob Kubernetes resource.
Note that to run by Cronjob, you have to configure SLACKDUTY_EXTERNAL_TRIGGER to true because it will no use the internal cron, it will use the Kubernetes cron to execute the job.

First, create a secret for API keys.

$ kubectl create secret generic slackduty-api-key --from-literal=slack-api-key=$SLACKDUTY_SLACK_API_KEY --from-literal=pagerduty-api-key=$SLACKDUTY_PAGERDUTY_API_KEY

Second, create a Config Map for the config file.

$ kubectl create configmap slackduty-configmap --from-file $SLACKDUTY_CONFIG

Then deploy the Cronjob. Schedule is the entire schedule trigger.

            imagePullPolicy: IfNotPresent
            env:
              - name: SLACKDUTY_EXTERNAL_TRIGGER
                value: "true"
              - name: SLACKDUTY_CONFIG
                value: /root/.slackduty/config.yml
              - name: SLACKDUTY_PAGERDUTY_API_KEY
                valueFrom:
                  secretKeyRef:
                    name: slackduty-api-key
                    key: pagerduty-api-key
              - name: SLACKDUTY_SLACK_API_KEY
                valueFrom:
                  secretKeyRef:
                    name: slackduty-api-key
                    key: slack-api-key
            args:
              - "/bin/slackduty"
            volumeMounts:
              - name: slackduty-config
                mountPath: /root/.slackduty/config.yml
                subPath: config.yml
          restartPolicy: OnFailure
          volumes:
            - name: slackduty-config
              configMap:
                name: slackduty-config

How to configure

Slackduty will read the SLACKDUTY_CONFIG path for config.yml. If not configured, it will read the default path ~/.slackduty/config.yml.

This is one example of Slackduty configuration.

groups:
  - name: "Example usergroup"
    schedule: "0 0 12 * *" 
    usergroups:
     - "handle:slackduty-oncall"
    members: 
      slack: 
        - "email:manager@slackduty.com"
      pagerduty:
        users:
          - "name:keke@slackduty.com"
        services:
          - "name:slackduty-frontend"
        teams:
          - "name:slackduty-web"
          - "name:slackduty-node"
        schedules:
          - "name:web-oncall"
      exclude:
        - "name:boss@slackduty.com"

Here are the details of the group object.

field	description	examples	required
name	The name of the group.	Keke on-call group	❌
schedule	Schedule of the sync between Slack usergroup and Pagerduty resources	0 0 * * *	✅(if SLACKDUTY_EXTERNAL_TRIGGER is not configured)
usergroups	Usergroup(s) that members belongs	handle:slackduty-oncall-members	✅
members	Members that belongs to the usersgroups. Slack user and PagerDuty resources can be specified.	-	✅
