Alerts/Alarm

Get notification from monitor system

Run Book

Check

Check status of application/system

Restart service

If service is unhealthy, try to restart service Create a incident ticket to JIRA

Reboot instance

If service is still going unhealthy after restart, try to make snapshot for inspection

And reboot instance

Terminate instance

Finally, terminate instance to bring new one automatically

Spinnaker Pipeline

Pipelines are the key deployment management construct in Spinnaker. They consist of a sequence of actions, known as stages.

SOSCON 2018Spinnaker

Multi-Cloud Continuous Delivery platform for releasing software changes with high velocity and confidence.

Key features• Delivery Pipelines• Deployment Strategies• Cluster Management• Jenkins Integration• Supports Multi Cloud

(AWS, GCP, Azure, Kubernetes, ECS, DC/OS, Cloud Foundry)

We have experience in utilizing and hosting Spinnaker about 2 years.
