Why public cloud?

Classical Deployment

Cloud Installation

And the result is ...

What went wrong?

Culture

  • Manual approvals

Technology

  • Manual installations

Automation

Automating virtual Infrastructure

  • DIY REST (curl, jq)
  • libcloud
  • heat
  • scalr
  • terraform
  • cliqr
  • bosh
  • juju
  • ansible
  • ...

OpenStack REST API

cloud-init

- controlled by meta-data src

- run upon first boot

- user accounts, ssh keys

- hostname, timezone

- networks, mounts

- package updates & installation

- arbitrary scripts

- phone home

- OTC: Inject files into /etc/cloud/cloud.cfd.d/

Config Mgmt Tools

- puppet, chef, ansible, saltstack

- run repeatedly to ensure compliance or changes

- configuration properties

- software packages

 

- can control infra as well

#ECS Creation status: SUCCESS 

Using OpenStack CLI tools

  •     Compute (nova v2) - Nova: 2.22.0 – 2.23.3 (Kilo)
  •     Images (glance v2) - Glance: 0.15.0 – 0.16.0 (0.17.x does not work, 1.1.0 does)
  •     Block Storage (cinder v2) - Cinder: 1.1.1 – 1.3.1 (all versions tested worked)
  •     Networking (neutron v2) - Neutron: 2.3.11/2.3.12 (newest versions fail)
  •     IAM (keystone v3) - Keystone: 1.3.4 (only libs needed, client itself deprecated)
  •     OpenStack: 1.0.4 – latest

OTC is based on OpenStack Juno plus backports plus extensions ...

Recommended client tools

Preinstalled in openSUSE42.x images (OBS)

docker container (Ubuntu) - docker pull tsiotc/otc-client/

Use pip otherwise

Previously a third step (port create) would have been needed

CLI summary

We cheated:

  • Network(VPC), subnet, keypair preexisting
  • Can be created using otc or openstack CLI tools
    (the latter since shortly, thanks to neutron update)
  • Complete example will be shown in next blog ...

 

Real world example:

  • Two AZ setup
  • JumpHosts, Loadbalancers, Database, BT, Web Tier
     

Somewhat tedious ...

Loadbalancers need non-native calls
