Automating OnCall Summary Page Generation

This is final part of 3 part series discussing automation of generating on call summary of PagerDuty incidents into a Notion page. In this blog we will discuss combining everything we did in last 2 parts and schedule it using K8 CronJob.

PagerDuty is designed to alert clients to disruptions and outages through machine learning and automation. Notion is a collaboration platform with markdown support that integrates kanban boards, tasks, wikis, and databases.

Let’s first create a docker image. Assume the python file for collecting incidents from PagerDuty (Part 1) is named get_pd_incidents.py and python file for creating notion page (Part 2) is named create_notion_page.py. A simple Dockerfile will look like:

FROM python:3.7.1

# Install required dependencies

RUN pip3 install --upgrade pip

RUN pip3 install requests

RUN pip3 install pdpyras

RUN pip3 install notion

# Bundle app source

COPY get_pd_incidents.py /src/get_pd_incidents.py

COPY create_notion_page.py /src/create_notion_page.py

CMD ["python3", "/src/get_pd_incidents.py"]

 

Make sure the files are present in your current working directory where Dockerfile is present. Build the docker image using:

docker build . -t <docker_hub>/on-call-summary:0.0.0

Now let’s schedule the application using K8 CronJob. 

apiVersion: batch/v1beta1

kind: CronJob

metadata:

  name: on-call-summary

spec:

  schedule: “0 0 * * SUN"

  jobTemplate:

    spec:

      template:

        spec:

          containers:

          - name: on-call-summary

            image: <docker_hub>/on-call-summary:0.0.0

Save it to on-call-summary-cron.yml file and apply it using:

kubectl apply -f on-call-summary-cron.yml
