1 Containers OpenStack Murano brings Docker & Kubernetes to OpenStack Serg Melikyan software.mirantis.com January 27, 2015

2 Agenda Introduction Murano Kubernetes Empowering Docker on OpenStack Kubernetes on OpenStack Get involved! Copyright 2015 Mirantis, Inc. All rights reserved

3 Introducing Murano What Murano is about? Copyright 2015 Mirantis, Inc. All rights reserved

4 Murano Application Catalog for Openstack Mission: Introduce an application catalog to OpenStack, enabling application developers and cloud administrators to publish various cloud-ready applications in a browsable categorized catalog.

5 Roles End-user Browse catalog Create deployment from building blocks Cloud Administrator Provide applications to the users Control content & usage Application Developer Develop applications using known SDK Deliver own applications to different clouds Copyright 2015 Mirantis, Inc. All rights reserved

6 Use Cases Self-service application provisioning Integration of non-cloud resources with OpenStack Repeatable deployments for prod/staging environments Standard building blocks for different application stacks Abstraction of underlying IaaS resources Copyright 2015 Mirantis, Inc. All rights reserved

7 Murano Application catalog for OpenStack Provides dynamic applications configuration Application life-cycle actions Resource provisioning through Heat Supports Windows, Linux,... Supports multiple package formats HOT Templates Murano PL

8 Application Environments Composed of Applications and their Dependencies Detects the types of dependencies automatically Can be changed at any time HTTPd WordPress MySQL Murano Environment is a logical representation of multi-tier applications. It uses Murano applications as building blocks to create multiple layers of application stack.

9 Application Dependencies Nagios Monitoring Implementation Abstract Monitoring monitoring Ceilometer Monitoring Implementation Zabbix Monitoring Implementation Your own Monitoring Implementation

10 Introducing Kubernetes What Kubernetes is about? Copyright 2015 Mirantis, Inc. All rights reserved

11 Kubernetes Manager for container clusters Mission: Introduce an cluster management system for Linux containers as a single system to accelerate Dev and simplify Ops..

12 Kubernetes Node - is a worker node in Kubernetes Pod - A pod corresponds to a colocated group of applications running with a shared context

13 Replications & Discovery
