ApacheCloudStack ApacheCloudStack Presentation Transcript

  • Infrastructure as code withPuppet and Apache CloudStackDavid Nalleyke4qqq@apache.org@ke4qqq
  • #whoami• Apache Software Foundation Member• Apache CloudStack PMC Member• Recovering Sysadmin• Fedora Project Contributor• Zenoss contributor• Employed by Citrix in the Open Source Business Office
  • Setting the stageApache CloudStack is...● an open source IaaS platform● proven in production at massive scale● awesome
  • Gorgeous UI
  • API● Native: http://cloudstack.apache.org/docs/api● EC2
  • IaaS removes one constraintNo longer waiting days or weeks to get a VM provisioned
  • but introduces another...Now you have to get a machine configured in a timelymanner.
  • Self service● UI● API● Some external tool
  • People provision stuff...Not ops folksOften not familiar with environmental intricaciesDont care
  • Baseline can be important....
  • ClassificationProblem: We spin up, dynamically, 1-500 VMs at any given time - how dowe decide what configurations apply.
  • ClassificationThe wrong way - dedicated images for each purpose
  • Classificationediting nodes.ppnode foo-356.cloud.com {include httpd}
  • Classificationglobbingnode mysql* {include mysqld}
  • ClassificationEverything is defaultnode default {include httpd}
  • ClassificationExternal Node Classifier
  • ClassificationExternal Node Classifier
  • ClassificationFactsclass base {case $::fact {httpd: {include httpd}otherrole: {include nginx}}}
  • Classification - One Solution● During instance provisioning define metadata.● Custom fact for that metadata● Case statement based on that fact
  • Example Metadatarole=webserverlocation=datacenter1environment=production
  • Corresponding manifestclass base {case $::fact {webserver: {include httpd}database: {include postgresql}}}
  • Corresponding manifestclass base {case $::fact {webserver: {include httpd}database: {include postgresql}}}
  • Links, et al.● Fact:http://s.apache.org/acs_userdata● Blog with details:http://s.apache.org/acs_userdata2
  • Video - go watch it● I only have 45 minutes - so cant delveinto everything, you should watch thevideo- it’s great.● http://youtu.be/c8YWctfOpwo

  • And then there was a knife-pluginThe folks at Edmunds.com wrote a knife plugin forCloudStackThe knife plugin had the ability to define an applicationstack, potentially hundreds of nodes, that are interrelated,and provision them with a single knife command.https://github.com/cloudstack-extras/knife-cloudstack
  • Deploying a machine with knife~ knife cs server create
  • {"name": "hadoop_cluster_a","description": "A small hadoop cluster with hbase","version": "1.0","environment": "production","servers": [{"name": "zookeeper-a, zookeeper-b, zookeeper-c","description": "Zookeeper nodes","template": "rhel-5.6-base","service": "small","port_rules": "2181","run_list": "role[cluster_a], role[zookeeper_server]","actions": [{ "knife_ssh": ["role:zookeeper_server", "sudo chef-client"] }]},{"name": "hadoop-master","description": "Hadoop master node","template": "rhel-5.6-base","service": "large","networks": "app-net, storage-net","port_rules": "50070, 50030, 60010","run_list": "role[cluster_a], role[hadoop_master], role[hbase_master]"},{"name": "hadoop-worker-a hadoop-worker-b hadoop-worker-c","description": "Hadoop worker nodes","template": "rhel-5.6-base","service": "medium","port_rules": "50075, 50060, 60030","run_list": "role[cluster_a], role[hadoop_worker], role[hbase_regionserver]","actions": [{ "knife_ssh": ["role:hadoop_master", "sudo chef-client"] },{ "http_request": "http://${hadoop-master}:50070/index.jsp" }]}}
  • Deploy that Hadoop cluster withknife cs stack create hadoop_cluster_a
  • I was jealous....
  • Then at FOSDEM 2012● CloudStack user shows me Puppet types and resourcesfor OpenNebula.● https://puppetlabs.com/blog/puppetizing-opennebula/● They indicated they wanted this awesomeness forCloudStack....
  • Why?● They wanted to define each of their applicationstacks in puppet, so that not only the configurationof software on the machine, but the machinesthemselves would be configured by Puppet.● Automated deployment of test environments thatare exactly the same● Really gets outside of machine configuration toentire infrastructure configuration
  • What we are used to● Puppet _defines_ the configurationwithin the machine
  • What we want● Puppet _defines_ the machine.● Puppet _defines_ collection ofmachines● Puppet _defines_ the machines,networks, and rest of infrastructure
  • Then at Puppetconf● There was Google ComputeEngine types and resources forPuppet.● Dan Bode gave a presentation showing off the work hehad done... that presentation is worth seeing...● http://www.slideshare.net/bodepd/google-compute-presentati
  • And then for Christmas● puppet types and providers arrived - courtesy of DanBode● https://github.com/bodepd/cloudstack_resources
  • How does this work?cloudstack_instance { foo1:ensure => present,flavor => Small Instance,zone => FMT-ACS-001,image => CentOS 5.6(64-bit) no GUI(XenServer),network => puppetlabs-network,# domain# account# hostname}●
  • Setting defaultsCloudstack_instance {image => CentOS 6.3,flavor => M1.medium,zone => San Jose,network => davids_net,keypair => david_keys,}cloudstack_instance {ensure => $::ensure,group => role=db,}
  • A simple stackclass my_web_stack {cloudstack_instance { foo4:ensure => present,group => role=apache,}cloudstack_instance { foo5:ensure => present,group => role=db,}}
