Nuxeo Studio

�6

Nuxeo.io

• Our approach to PaaS

• Provide one-click Nuxeo deployment to our users

• Integrates all of our services (Studio, Market place, custom add-ons)

• Allow easy and fast deployment

Running Nuxeo(s) in Docker

�8

Running Nuxeo in Docker

�9

• Nuxeo is Java based : runs in Tomcat

• Needs a DB : PostgreSQL

• With some utils• poppler-utils (pdf2html)

• OpenOffice (yes it’s an « util »)

• ImageMagick (image conversion)

Reverse Proxy

• Running a lot of docker container may be harmful !

• We need some tooling to manage that

�15


Managing a cloud Platform

�16

Managing a cloud platform

• We need to • Be aware of cluster’s state

• Be able to launch services

• Resilient

�17


• Based on The Grid (aka Flynn Layer0 http://flynn.io)

• Backed by CoreOS (http://www.coreos.com), small linux distro which provides• etcd (distributed registry)

• systemd (replacement for init.d)

• of course docker

Managing a cloud platform• etcd provides a way to share cluster state

• Why use a « soft » reverse proxy• No service « restart » = full dynamic

• Allow to intercept calls for metrics

• Useful for passivation

• Allow to deal with interruptions of service

• Ask the user to wait

• Ask the cluster to start a new instance

�25

Actual State

• Labs using Vagrant on bare metal

• Still have to know how to start nuxeo container ;-)• via a systemd service

• like a job via flynn-host

• POC on AWS for end of february

�26

Conclusion

• Docker allows us to start/stop new instances very fast

• It allows to design an infrastructure that is not tied to IaaS provider (but can be run onto)

• Very young ecosystem/tools like etcd, discoverd, flynn stack etc…
