What are we going to talk about?

NoOps
Cloud Applications
Puppet
Ansible

+ +

NoOps

NoOps means developers can code and let a service deploy, manage and scale their code

I don't want to "do ops"

I want to change the system by landing commits

If I have to use my root access, it's a bug

+ +

Cloud Native

Ephemeral Compute
Data services
Design your applications to be resilient via scale out

+ +

Cloud Scale Out

Forget HA of one system
Forget long-lived systems
Shared-nothing for EVERYTHING

+ +

Cloud Scale Out is great for new applications

+ +

What about existing applications?

+ +

OpenStack Infra

+ +

Tooling, Automation and CI for OpenStack Project

+ +

2000 Developers

+ +

Gated Commits

Every commit is fully integration tested (twice) before landing

+ +

Each Test Runs on a Single Use Cloud Slave

This is that "cloud scale out" part

+ +

1.7 Million Test Jobs in the last 6 Months

+ +

15 Million Tests in December

+ +

18 Terabytes of Log Data in six months

+ +

We have no servers

It all runs across HP and Rackspace Public Clouds.

+ +

Architecture

+ +

It didn't start this way

+ +

Step One: Puppet

+ +

Overview

Open Source Config Management System
Written in Ruby
Models intended state
Wants to own entire system

+ +

Config Management is Great

Repeatable and consistent machines
Code Review
Collaboration from non-root users
Less repetition for me
Open Source Infrastructure
http://git.openstack.org/cgit/openstack-infra/system-config/
http://puppetdb.openstack.org/

+ +

Ruby DSL


+package { 'git':
+  ensure => 'present',
+}
+

+ +

Leaky Abstraction


+if !defined(Package['git']) {
+  package { 'git':
+    ensure => 'present',
+  }
+}
+

+ +

Three ways to run

puppet apply
puppetmaster + puppet agent daemons
puppetmaster + puppet agent non-daemon

+ +

Managing users and ssh keys


+define user::virtual::localuser(
+  $realname,
+  $groups     = [ 'sudo', 'admin', ],
+  $sshkeys    = '',
+  $key_id     = '',
+  $old_keys   = [],
+  $shell      = '/bin/bash',
+  $home       = "/home/${title}",
+  $managehome = true
+) {
+
+  group { $title:
+    ensure => present,
+  }
+

+ +

Managing users and ssh keys (cont.)


+  user { $title:
+    ensure     => present,
+    comment    => $realname,
+    gid        => $title,
+    groups     => $groups,
+    home       => $home,
+    managehome => $managehome,
+    membership => 'minimum',
+    shell      => $shell,
+    require    => Group[$title],
+  }
+

+ +

Managing users and ssh keys (cont.)


+  ssh_authorized_key { $key_id:
+    ensure  => present,
+    key     => $sshkeys,
+    user    => $title,
+    type    => 'ssh-rsa',
+  }
+
+  if ( $old_keys != [] ) {
+    ssh_authorized_key { $old_keys:
+      ensure => absent,
+      user   => $title,
+    }
+  }
+}
+

+ +

Our code is Open Source, right? What about passwords and keys ...

+ +

hiera

Simple YAML database, sits on puppetmaster
Use it for secret data
puppet code is still complete


+node default {
+  class { 'openstack_project::server':
+    sysadmins => hiera('sysadmins', []),
+  }
+}
+

Breaks ability to use simple puppet apply

+ +

Step Two: Ansible for Orchestration

+ +

About Ansible

Open Source System Management tool
Written in Python
Sequence of steps to perform
Works over SSH
Incremental Adoption

+ +

ad-hoc operation

+ansible '*' -m shell -p uptime
+

+ +

YAML Syntax


+- hosts: '*.slave.openstack.org'
+  tasks:
+    - shell: 'rm -rf ~jenkins/workspace/*{{ project }}*'
+

That's executed:

+ansible-playbook -f 10 /etc/ansible/clean_workspaces.yaml --extra-vars "project=$PROJECTNAME"
+

+ +

Ansible Organization

modules
plays
playbooks
roles

+ +

Use Ansible to Run Puppet!

+ +

puppet module

def main():
+    module = AnsibleModule(argument_spec=dict(
+        timeout=dict(default="30m"),
+        puppetmaster=dict(required=True),
+        show_diff=dict(default=False, aliases=['show-diff'], type='bool'),
+    ))
+    p = module.params
+
+    puppet_cmd = module.get_bin_path("puppet", False)
+    if not puppet_cmd:
+        module.fail_json(msg="Could not find puppet. Please ensure it is installed.")
+

+ +

puppet module (cont)


+    cmd = ("timeout -s 9 %(timeout)s %(puppet_cmd)s agent --onetime"
+           " --server %(puppetmaster)s"
+           " --ignorecache --no-daemonize --no-usecacheonfailure --no-splay"
+           " --detailed-exitcodes --verbose") % dict(
+               timeout=pipes.quote(p['timeout']), puppet_cmd=PUPPET_CMD,
+               puppetmaster=pipes.quote(p['puppetmaster']))
+    if p['show_diff']:
+        cmd += " --show-diff"
+    rc, stdout, stderr = module.run_command(cmd)
+

+ +

+ Please. Everyone. Marvel at the following logic +


+    if rc == 0:  # success
+        module.exit_json(rc=rc, changed=False, stdout=stdout)
+    elif rc == 1:
+        # rc==1 could be because it's disabled OR there was a compilation failure
+        disabled = "administratively disabled" in stdout
+        if disabled:
+            msg = "puppet is disabled"
+        else:
+            msg = "puppet compilation failed"
+        module.fail_json(rc=rc, disabled=disabled, msg=msg, stdout=stdout, stderr=stderr)
+    elif rc == 2:  # success with changes
+        module.exit_json(changed=True)
+    elif rc == 124:  # timeout
+        module.exit_json(rc=rc, msg="%s timed out" % cmd, stdout=stdout, stderr=stderr)
+    else:  # failure
+        module.fail_json(rc=rc, msg="%s failed" % (cmd), stdout=stdout, stderr=stderr)
+

+ +

puppet play


+- name: run puppet
+  puppet:
+    puppetmaster: "{{puppetmaster}}"
+

+ +

puppet role

roles/puppet/tasks/main.yml

+ +

remote puppet playbook


+- hosts: git0*
+  gather_facts: false
+  max_fail_percentage: 1
+  roles:
+    - { role: puppet, puppetmaster: puppetmaster.openstack.org }
+- hosts: review.openstack.org
+  gather_facts: false
+  roles:
+    - { role: puppet, puppetmaster: puppetmaster.openstack.org }
+- hosts: "!review.openstack.org:!git0*:!afs*"
+  gather_facts: false
+  roles:
+    - { role: puppet, puppetmaster: puppetmaster.openstack.org }
+

+ +

ansible inventory

List of servers to operate on
Optionally variables associated with each server
Optional groups of servers
Simple yaml file in /etc/ansible/hosts
Dynamic executable that returns JSON

+ +

Simple inventory

+review.openstack.org
+git01.openstack.org
+git02.openstack.org
+pypi.dfw.openstack.org
+pypi.iad.openstack.org
+
+[pypi]
+pypi.dfw.openstack.org
+pypi.iad.openstack.org
+
+[git]
+git01.openstack.org
+git02.openstack.org
+

+ +

ansible inventory from puppet certs


+import json
+import subprocess
+
+output = [
+    x.split()[1][1:-1] for x in subprocess.check_output(
+        ["puppet","cert","list","-a"]).split('\n')
+    if x.startswith('+')
+]
+
+data = {
+    '_meta': {'hostvars': dict()},
+    'ungrouped': output,
+}
+print json.dumps(data, sort_keys=True, indent=2)
+

+ +

Step Three: Ansible for Cloud Management

+ +

ansible and OpenStack

Ansible modules are just python
playbooks are lists of steps to take
Have plays/roles that provision servers
Infrastructure as code - for real!

+ +

Consider this data


+pypi.dfw.openstack.org:
+  image_name: Ubuntu 12.04.4
+  flavor_ram: 2048
+  region: DFW
+  cloud: rackspace
+  volumes:
+    - size: 200
+      mount: /srv
+pypi.region-b.geo-1.openstack.org:
+  image_name: Ubuntu 12.04.4
+  flavor_ram: 2048
+  region: region-b.geo-1
+  cloud: hp
+  volumes:
+    - size: 200
+      mount: /srv
+

+ +

Further consider this data


+pypi:
+  image_name: Ubuntu 12.04.4
+  flavor_ram: 2048
+  volumes:
+    - size: 200
+      mount: /srv
+  hosts:
+    pypi.dfw:
+      region: DFW
+    pypi.iad:
+      region: IAD
+    pypi.ord:
+      region: ORD
+    pypi.region-b.geo-1:
+      cloud: hp
+

+ +

Steps to launch a node

Create a compute instance
Wait for instance to exist
Create a floating IP
Attach floating IP to instance
Create one or more volumes
Attach volumes to instance
Wait for SSH to work
On host, format each volume
On host, mount each volume
On host, install config management software
On host, run config management software

+ +

Launch a node


+---
+- name: Launch Node
+  os_compute:
+      cloud: "{{ cloud }}"
+      region_name: "{{ region_name }}"
+      name: "{{ name }}"
+      image_name: "{{ image_name }}"

+      cloud: "{{ cloud }}"
+      size: "{{ item.size }}"
+      display_name: "{{ item.display_name }}"

+      server_id: "{{ node.id }}"
+      volume_name: "{{ item.display_name }}"
+  with_items: volumes
+  register: attached_volumes
+- debug: var=attached_volumes
+- name: Re-request server to get up to date metadata after the volume loop
+  os_compute_facts:
+      cloud: "{{ cloud }}"
+      name: "{{ name }}"
+  when: attached_volumes.changed
+- name: Wait for SSH to work
+  wait_for: host={{ node.openstack.interface_ip }} port=22
+  when: node.changed == True
+- name: Add SSH host key to known hosts
+  shell: ssh-keyscan "{{ node.openstack.interface_ip|quote }}" >> ~/.ssh/known_hosts
+  when: node.changed == True
+- name: Add all instance public IPs to host group
+  add_host:
+      name: "{{ node.openstack.interface_ip }}"
+      groups: "{{ provision_group }}"
+      openstack: "{{ node.openstack }}"
+  when: attached_volumes|length == 0
+- name: Add all instance public IPs to host and volumes group
+  add_host:
+      name: "{{ node.openstack.interface_ip }}"
+      groups: "{{ provision_group }},hasvolumes"
+      openstack: "{{ node.openstack }}"
+  when: attached_volumes|length != 0
+

+ +

Cloud based inventory

Just ask the cloud for the inventory
All of the meta-data the cloud knows is available
No need for puppetmaster now

+ +

Wait - what about secrets?

ansible can just pass secrets to puppet apply as parameters

+ +

Step Four: Just get rid of puppet ...

but that's another talk

When you boot a VM, it needs boot time data or bootstrapping

+ +

I use ansible for orchestration

+ +

I don't need boot time fancy, + I JUST need ssh bootstrap

Ok. And maybe network

+ +

Things I must consume at boot

+ Network Configuration +
+ maybe SSH Keys +

+ +

Network information should be easy

There is this thing called DHCP

Dynamic Host Configuration Protocol

+ +

Some providers don't support DHCP - because bong

+ +

cloud-init

Handles many cases, but not all

Has lots of dependencies that conflict with gate depends

'frozen' pending 2.0 rewrite

+ +

glean

http://git.openstack.org/cgit/openstack-infra/glean

No dependencies

Handles future static network config in config drive

Optionally also reads ssh keys from config drive

Nothing else

Borrowed from Ubuntu

Time Based Releases

Six Month Cadance

Lemming?

Lemming Peak

+ +

The Marketing Community was not thrilled

+ +

Lemmings commit mass suicide by following each other off cliffs

+ +

Except they don't

+ +

White Wilderness

1958 Disney Documentary

Staged footage

Camera crew forced them off the cliff

Won an Oscar, of course

+ +

Definition of Irony

The actual meaning is the opposite of the literal meaning

+ +

Recursive Definition of Irony

The lemmings metaphor only works because people are lemmings in their adherence to the myth that lemmings are like lemmings.

+ +

This could never happen to us, right?

MySQL doesn't have transactions

MongoDB is Web Scale

PHP is insecure

Frequent password rotation is secure

sysvinit needs to be replaced

+ +

Results

We didn't pick Lemming - we picked Liberty

Liberty is a town in Saskatchewan

+ +

Four Freedoms

0 - to run the program as you wish, for any purpose

1 - to study how the program works, and change it so it does your computing as you wish

2 - to redistribute copies so you can help your neighbor

3 - to distribute copies of your modified version to others

+ +

GPL is anti-business

+ +

Except it isn't

+ +

Definition of Eating Crow

humiliation by admitting wrongness or having been proven wrong after taking a strong position

+ +

Enjoyable Definition of Eating Crow

Microsoft purchases Revolution Analytics

R language is GPL

+ +

Sun/MySQL

Sun bought MySQL for $1 Billion

Oracle bought Sun

Oracle now develops and ships MySQL under the GPL

+ +

Linux

anybody here heard of it?

+ +

Android is the market leading Mobile OS
+

+ +

Linux runs:

Google

Facebook

Twitter

They run MySQL too

+ +

Linux is not just for big companies - it's startup friendly too!

+ +

HP ships a Linux server every minute

business unit that does is a $28B business

+ +

Why is Free Software Important?

+ +

1984 - Apple's 1984 Super Bowl Commercial

1985 - Apple's Lemmings Super Bowl Commercial

1997 - Apple's Think Different Campaign

+ +

Don't be a lemming

+ +

Everybody in this room is wearing a uniform and don't kid yourself

Frank Zappa

+ +

"Think Different" isn't about allowing for individualism, it's about defining an alternate tribe

And don't kid yourself, it's about selling product

+ +

What if you're this poor fellow?

http://worstcats.tumblr.com

+ +

How much of your life is computerized?

How many of the four freedoms do you have with each of those things?

+ +

superfish
+
My laptop did not come with any software pre-installed that is designed to "improve my shopping experience"
+
If it had, I am empowered to remove it
+

+ +

Why are we here? I think many people assume, wrongly, that a company exists solely to make money. Money is an important part of a company's existence, if the company is any good. But a result is not a cause. We have to go deeper and find the real reason for our being.

David Packard

+ +

Free Software is a way that I can make the world a better place

+ +

Free Software is a way to reconnect with our humanity in a sea of white privilege

+ +

Free Software drives an unprecedented amount of innovation

Believe you can change the world

What are we going to talk about?

OpenStack
My application
Your applications

+ +

As an application developer,
+ I want to deploy and run an application on the internet

As an application developer,
+ I want to deploy the application across multiple clouds
+ so that my service survives issues in any one of them.

THIS WORKS

I'm doing it myself as we speak

10-20k VMs per-day

3 (soon to be 6) clouds

Only using OpenStack APIs

OpenStack Works!

What next?

Make it easier

+ +

Basic things you want to do

+ +

Get (make/fetch/find) a base image

Upload it to each cloud

Boot a VM on one or more of the clouds

Ensure it's on the Internet

+ +

We've made this harder than it should be

+ +

Get a base image

OpenStack diskimage-builder

packer

Download pre-built image from Ubuntu/RedHat/SuSE

+ +

Problem: hypervisor image file format

+ Rackspace uses VHD +
+ HP uses qcow2 +
+ DreamHost uses RAW +

+ +

Problem: image API version

+ HP uses v1 +
+ vexxhost uses v2 +

Good news! We made a plan for this at + the summit

+ +

Problem: image task vs. PUT

+swift upload --object-name local-image-filename images image-name
+glance task-create
+   --type=import
+   --input='{"import_from": "images/image-name",
+             "image_properties" : {"name": "My Image Name"}}'
+

+glance image-create --name=image-name --file=local-image-filename
+

+ +

Problem: Ensure it's on the Internet

Cloud has externally routable IP from neutron (RunAbove, OVH)
Cloud has externally routable IP neutron AND supports optional private tenant networks (vexxhost)
Cloud has private tenant network provided by neutron and requires floating IP (HP, Dreamhost)
Cloud only has private tenant network provided by nova-network and requires floating-ip for external routing (auro)
Cloud has externally routable IP from neutron but no neutron APIs (Rackspace)

+ +

Maybe in code ...

+def get_server_external_ipv4(cloud, server):
+    if cloud.has_service('network'):
+        try:
+            server_ports = cloud.search_ports(
+                filters={'device_id': server.id})
+            ext_nets = cloud.search_networks(filters={'router:external': True})
+        except NeutronClientException as e:
+            pass  # fall through
+        else:
+            for net in ext_nets:
+                for port in server_ports:
+                    if net['id'] == port['network_id']:
+                        for ip in port['fixed_ips']:
+                            if _utils.is_ipv4(ip['ip_address']):
+                                return ip['ip_address']
+    ext_ip = get_server_ip(server, key_name='public')
+    if ext_ip is not None:
+        return ext_ip
+    for interfaces in server.addresses.values():
+        for interface in interfaces:
+            if _utils.is_ipv4(interface['addr']) and \
+                    _utils.is_globally_routable_ipv4(interface['addr']):
+                return interface['addr']
+    return None
+

+ +

I think we can do better than that

+ +

NO

+ +

Problem: My Internet server is behind a NAT

+ +

Problem: Security Groups

+
I was trying to spin up a web server, but all my ports were blocked
+
I'll be using ansible and puppet on this machine, I can configure iptables thanks
+

+ +

Boot a VM on one or more of the clouds

+nova secgroup-add-rule default tcp 80 80 0.0.0.0/0
+nova boot --image=image-name --flavor=something --name=my-server
+nova floating-ip-create
+nova floating-ip-associate my-server {{ value_from_create }}
+

+ +

Wow. So that's

+ Image Format +
+ Image API version +
+ Image upload mechanism +
+ Networking config / public private +
+ Networking config nova/neutron +
+ Floating IP? +
+ Floating IP nova/neutron +
+ DHCP or Static networking config +
+ Security Group config +

+ +

I think we can do better than that

+ +

What am I doing about it?

os-client-config

http://git.openstack.org/cgit/openstack/os-client-config

A library to handle config information for openstack clients

Tracks differences in vendors that can't be discovered

In use in python-openstackclient and ansible today

Raising Issues

Product Management Working Group (today, 2pm, room 212)
DefCore (Wednesday 10:30 - 12:30, East Building Room 2/3)
Direct interaction with the teams and PTLs

+ +

What should we do about it?

+ Get back to basics +
+ shade existence is a bug +
+ Make some decisions about divergences in the basic levels +
+ Take a stand even if one of our product managers disagrees +
+ Ensure that simple things are simple +

+ + +

Thank you!

What are we going to talk about?

TripleO
Ironic
Ansible

+ +

What is TripleO?

an idea
OpenStack On OpenStack
use Ironic-based OpenStack to Operate Openstack

+ + +

Velocity

Cloud Empowers developers
Cloud Enables Increased Velocity
Cloud Drives Agility

+ +

OpenStack is not a virtualization layer, + it's an abstraction layer.

+ +

What if your developers aren't writing Angry Birds?

+ +

What if your developers aren't developers?

+ +

If infrastructure is code ...

What if your developers are operators?

+ +

Why wouldn't you give your operators the same power as your + developers?

Don't you like them?

+ +

Ironic is a service capable of
+ managing and provisioning
+ physical machines.

+ +

Nova + Ironic

+ Same but different + +

What can you do?

anything - it's a cloud

+ +

What the heck has the TripleO team been doing then?

+ +

TripleO

Community developed
Opinionated
Avoid distro and config management religion
Be a usable real deployment we can gate on

+ +

Community Developed

Exist as part of the OpenStack project
Prove the story end to end
Subject to TC governance
Tighter feedback loop

+ +

Avoid distro and config management religion

rpm vs. deb - in the gate == rpm + deb
puppet vs. chef vs. salt vs. ansible == all of them
Choosing one excludes other folks from participating

+ +

Opinionated

Golden Images
Upgrade tied to HA
Target Continual Delivery
Drive fixes into OpenStack directly

Lesson from os-*-config

If you ever think "oh, that's silly, it would be so much easier + if I just ..."
it will almost never actually be easier if you + just ...

+ +

The Deployment Story

disk-image-builder builds images and uploads to glance
Heat drives Nova/Ironic
Heat delivers metadata to os-collect-config
os-collect-config applies any in-instance changes needed

+ +

The Update Story

Heat magically just updates things +

+ +

BUT I ALREADY USE ?????

(screw you guys, I'm going home)

+ +

Yeah, I do to

(I use puppet and ansible myself)

+ +

That's fine - use them - it's a cloud!

This is supposed to be empowering, not enforcing

+ +

Whatever you want!

Heat to deploy and update images, os-*-*config for config
Heat to deploy images, ansible to update images, puppet for config
Ansible to deploy base image + packages, salt to update packages, chef for config
juju to deploy ... nah, I'm just kidding

+ +

The New Update Story

Ansible takes over for upgrades

+ +

Ansible for Orchestration

ansible and OpenStack

Ansible modules are just python
playbooks are lists of steps to take
Have plays/roles that provision servers
Infrastructure as code - for real!

Steps to launch a node

Create a compute instance
Wait for instance to exist
Create a floating IP
Attach floating IP to instance
Create one or more volumes
Attach volumes to instance
Wait for SSH to work
On host, format each volume
On host, mount each volume
On host, install config management software
On host, run config management software
