Transcript

1. Keeping OpenShift Evergreen Managing OpenShift clusters using Cloudsoft AMP Andrew Donald Kennedy Cloudsoft Corporation, April 2017
2. Introduction Andrew Donald Kennedy – Cloudsoft Corporation Distributed Systems Hacker Open Source Contributor Software Engineer @grkvlt
3. Agenda Cloudsoft AMP Introduction • Application Management • Docker, Kubernetes and OpenShift • Container Management • Orchestration OpenShift Automation • Deployment • Runtime Management • Effectors and Actions • Cluster Operations • Repave and Evergreening @grkvlt
4. Introduction to Cloudsoft AMP @grkvlt
5. Problem Solving Large and Complex Ecosystem Fast-moving Updates Complex Deployments Inconsistent Documentation Lack of Runtime Management @grkvlt
6. What Does AMP Do? MODEL DEPLOY MANAGE INSTANTIATE SENSE EFFECT Capture Best Practices Dynamic Live Model Maintain SLAs My Model Apache Tomcat MySQL Load Balancer @grkvlt
7. AMP – Infrastructure Agnostic Physical Virtual Local – Private - Dedicated Public @grkvlt
8. Application Management Runtime management of deployed applications. Policies use application-specific metrics such as latency or transactions per second, averaged across groups of services to give meaningful results. Operations like scaling, failover and service monitoring can be added to any application blueprint using these policies. @grkvlt
9. Enterprise Problem Solving Need reliable cloud-native application patterns to be competitive Management is tied to infra layer with manual or missing processes for applications and services, causing risk and hindering adoption Increasingly diverse platforms & infrastructure mean applications are hard to track, increasing the cost & risk of digital transformation @grkvlt
10. Container Services Deploy and manage Docker Swarm clusters and Kubernetes clusters. Production-ready infrastructure with TLS, high-availability and extensions like Flannel, Calico and Canal for networking. Can also connect to existing infrastructure provisioned and managed externally, by specifying appropriate API endpoints. Containerize applications by simply deploying blueprints to container-aware locations or build hybrid applications from virtual machines, containers and pods. @grkvlt
11. OpenShift Deployment @grkvlt
12. OpenShift Deployment Deploying OpenShift in the cloud Uses Red Hat Ansible playbook Configurable cluster composition Runtime management and control Complex operations from primitive actions @grkvlt
13. OpenShift Origin Blueprint @grkvlt location: red-box-openstack-cloud services: - type: openshift-origin-template name: "OpenShift Origin" brooklyn.config: openshift.version: 1.4.1 openshift.master.clusterSize: 2 openshift.etcd.clusterSize: 3 openshift.node.clusterSize: 5 openshift.node.minCores: 4 openshift.node.minRam: 8000 openshift.domain: "openshift.local"

17. Cloudsoft AMP OpenShift Deployment @grkvlt AMP Console...
18. OpenShift Automation @grkvlt
19. OpenShift Automation Monitor cluster activity and status Add new nodes to the cluster Replace machines when failure detected Grow cluster under load or automatically Update operating system and services @grkvlt
20. OpenShift Automation Effectors defined for AMP entities Perform simple tasks or compose others Start and stop OpenShift processes Manage pods and node status Resize clusters and add new capacity @grkvlt
21. OpenShift Origin Automation Example @grkvlt - type: org.apache.brooklyn.core.effector.ssh.SshCommandEffector brooklyn.config: name: selectOldestNodes description: | Get the K oldest nodes parameters: k: description: | The number of nodes to get command: | oc get nodes \ --sort-by='.metadata.creationTimestamp' \ --selector='region != infra' \ --output='name' | cut -d/ -f2 | head -${k} | paste -s -d\ -
22. OpenShift Automation Examples Combine individual small tasks... Sequence Compose Loop Choice Transform Replace Build useful tasks like repave @grkvlt
23. OpenShift Cluster Repave Actions Resize for new nodes — Fresh OS and patches Scale out cluster onto new nodes Drain tasks from oldest nodes and stop them Remove stopped nodes from cluster Execute as scheduled task periodically @grkvlt
24. OpenShift Cluster Repave Demo @grkvlt Repave Demo...
25. Questions…? @grkvlt Initial OpenShift Cluster
26. Questions…? @grkvlt @grkvlt AMP – Resize Cluster of Virtual machines
27. @grkvlt Ansible – Scale Out OpenShift Nodes
28. @grkvlt AMP– Select Oldest Nodes
29. @grkvlt AMP and OpenShift – Drain Nodes and Re-schedule Pods
30. @grkvlt AMP – Stop OpenShift Node Processes
31. @grkvlt AMP – Release Old Virtual Machines
32. @grkvlt Repaved OpenShift Cluster
33. OpenShift Cluster Repave Demo @grkvlt Continued...
34. Cloudsoft AMP and OpenShift @grkvlt
35. Cloudsoft AMP Velocity @grkvlt Consistency Control Grow effortlessly and Scale and dynamically with workloads Common management tooling across all applications from pets to cattle Agnostic so you can combine bare metal, virtual machines and containers Simple and consistent management view of applications
36. OpenShift Automation Deployment of OpenShift Origin Deploy applications to OpenShift Manage running OpenShift clusters Orchestrate actions across applications Evergreen clusters with repave @grkvlt
