So during Pure kickoff last week I did several sessions on Pure Storage and Kubernetes for our yearly Tech Summit. It was very fun to prepare for. I wanted to do something different and I decided to take my py-bot I was running on my raspberry pi and up-level with integration into K8s and the FlashBlade with PVC’s. This is the second post and covers how to build the docker container and deploy to k8s.

Check out the repo on github: https://github.com/2vcps/python-twitter-bot

Take a look at the code in ./bots

autoreply.py – code to reply to mentions
config.py – sets the API connection
followFollowers_data.py – Follows anyone that follows you, then writes some of their recent tweets to a CSV on a pure-file FlashBlade filesystem
followFollowers.py – All the followback with no data collection
tweetgamescore.py – future
tweetgamesetup.py – future

Py-bot In Kubernetes

Prereqs

python3
twitter account with API keys
Pure Service Orchestrator and working Kubernetes How to install Pure Service Orchestator CSI Plugin

Step 1

Build the docker image and push to your own repo. Make sure you are authenticated to your internal repo.

$ docker build -t yourrepo/you/py-bot:v1 .
$ docker push yourrepo/you/py-bot:v1

Step 2

Create a secret in your k8s environment with the keys are variables. Side note: this is the only methond I found to not break the keys when storing in K8s. If you have a functioning way to do it better let me know.

edit env-secret.yaml with your keys from twitter and the search terms.

kubectl apply -f env-secret.yaml

Verify the keys are in your cluster.

kuebctl describe secret twitter-api-secret

Step 3

Edit deployment.yaml and deploy the app. In my example I have 3 different deployments and one pvc. If you play to not capture data make sure to change the followback deployment to launch followFollowers.py and not followFollowers_data.py. Addiotionally, remove the PVC information if you are not using it.

Be sure to change the image for each deployemnt to your local repository path.
Notice that the autoreply deployment uses the env variable searchkey2 and favretweet deployment will use searchkey1. This allows each app to seach on different terms.

Be careful, if you are testing the favretweet.py program and use a common word for search you will see many many likes and retweets.

Now deploy

kubectl apply -f deployment.yaml

kubectl get pod
