3. Objetivos • Entender qué son y cómo se relacionan: Docker, Kubernetes y OpenShift • Conocer qué son OpenShift Online, OpenShift Origin y OpenShift Enterprise • Aprender a desplegar una aplicación simple en OpenShift ◦ Usando la web console ◦ Usando la command line interface
4. Containers, everywhere...
5. Docker • Provides an extra layer of abstraction and automation for containers deployment and administration ◦ Docker Engine ◦ DockerHub ◦ Dockerfile (YAML) ◦ Docker compose (YAML) • Contains the userspace (not kernel) • Guarantees isolation • Different use cases (!= VMs) • Different lifecycle
6. Kubernetes (k8s) • Automate deploying, scaling and operating application containers ◦ Scheduling ◦ Lifecycle and health ◦ Discovery ◦ Monitoring ◦ Security ◦ Scaling ◦ Persistence ◦ Aggregation • Desired-state concept • Open source
7. OpenShift • Designed for traditional and cloud native apps • Designed for development and production environments • Helps develop, build and manage container based applications • Polyglot • Straight k8s underneath: use kubectl to interact with OpenShift cluster
10. Deploying a simple app
11. OpenShift Online Starter OpenShift as a Service Free basic plan with the following, • 1 Project • 1GiB Memory Included • 1GiB Terminating Memory Included • 1GiB Storage Included • Resource Hibernation
12. Parksmap
13. Minishift Tool that helps you run OpenShift locally by running a single-node OpenShift cluster inside a VM. https://www.openshift.org/minishift/ 1. Get Minishift installer (GNU/Linux, Windows, MacOS) 2. Run minishift start 3. Hack, hack, hack!
