Implement Slack Notification
Create Slack Webhook
At first, create an incoming slack webhook. Necessary information is available in the slack api page. Once you create the webhook, you will get a URL similar to below example.
https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
is the secret part of the webhook which we would need in the next step.
Create slack-secret
Create a slack-secret.yaml
definition using the following command.
This will create a kubernetes secret named slack-secret.yaml
in the examples/sample-app/base
directory.
Before running this command change your current directory into examples/sample-app
.
kubectl create secret generic slack-secret --from-literal=SECURE_DATA='{"slack_hook":<YOUR_HOOK_SECRET>,"text":"Deployed PodTatoHead Application"}' -n podtato-kubectl -oyaml --dry-run=client > base/slack-secret.yaml
Enable post deployment task
To enable Slack notification add post-deployment-notification
in as a postDeploymentTasks in the
examples/sample-app/base/app.yaml
file as shown below.
postDeploymentTasks:
- post-deployment-notification
