Trillian - Build Nested CloudStack Environments

More detailed information can be found in the Wiki

Trillian makes use a 'parent' CloudStack' environment which is used to build virtualised nested environments.

Trillian leverages ESXi's ability to virtualise the VT-x features allowing the creation of VT-x enabled virtualised hosts

Trillian uses Ansible 2 to create environment configuration files and deploy those environments. The user can run 2 commandline statements and go from 0 to a running cloudstack environment with multiple hosts.

as an example:

ansible-playbook generate-cloudconfig.yml --extra-vars 'env_name=trillian-test-env env_comment='\''example nested cloudstack test environment'\''  use_shared_storage=true env_version=cs410 mgmt=1 db=0 hvtype=k  kvm_os=7 hv=2 env_accounts=all pri=2 sec=1 esxi_use_dvswitch=no build_marvin=yes wait_till_setup=yes wait_for_template=yes mgmt_os=7' -i localhost

at the end of this the sugestion, You can now run: ansible-playbook deployvms.yml -i ./hosts_trillian-test-env, is put on the output, which would trigger you to run something like

ansible-playbook deployvms.yml -i ./hosts_trillian-test-env --extra-vars 'env_name=trillian-test-env env_version=cs410'

for more examples see the Wiki

Basic variables:

  • env_name [mandatory]: Environment name, single string, characters, numbers, underscore _ or dash - only.

  • env_version [mandatory]: Environment CloudStack version (cs45, cs46, cs49, custom, etc).

  • mgmt_os [mandatory]: Management server OS (6, 7, u, custom)

  • hvtype [mandatory]: XenServer (x), KVM (k) or VMware (v)

  • pri [mandatory]: number of primary storage pools.

  • hv: number of hypervisors. Please note if hypervisor type is VMware the assumption is made that a single VC host is also required. This does not have to be specified anywhere.

    One of the following three is required depending on the choosen Hypervisor (hvtype):

    • kvm_os:
      • 6 = centos6.8
      • 7 = centos7.1
      • u = ubuntu14.04
    • xs_ver:
      • xs62sp1
      • xs65sp1
    • vmware_ver:
      • 55u3
      • 60u1

    In order to avoid template issues, kvm_os, xs_verand vmware_ver will default to 'custom' when they are not specified.

    If you specify KVM as hypervisor (hvtype=k) you must specify the kvm_os or set it to 'custom' and set the template to use (kvm_template) in the extra vars (kvm_template="Ubuntu Server 14.04")

    The same applies to the other hypervisor types. For custom VMware you would need to specify both the vCenter and ESXi templates

Advanced variables [all optional]:

  • mgmt: Number of management servers to configure (default is 1)
  • sec: number of secondary storage pools. (default is 1)
  • db: Number of database servers to configure (default is 0 - db is on mgmt host)
  • management_network: name of the management network
  • guest_public_network: name of the guest+public network
  • management_vm_hypervisor: parent CloudStack cloud hypervisor (default VMware)
  • build_project: project name to use for the nested cloudstack build (default -NestedClouds)
  • build_zone: parent cloud zone name
  • build_keyboard: keyboard used for nested VMs (default UK)
  • mgmtsrv_service_offering: parent cloud service offering used for the management server build
  • mgmtsrv_template: parent cloud template used for the management server build
  • dbsrv_service_offering: parent cloud service offering used for database server build
  • dbsrv_template: parent cloud template used for database server build
  • kvm_service_offering: parent cloud nested KVM instances service offering
  • kvm_template: parent cloud nested KVM HV template
  • xs_service_offering: parent cloud nested XenServer instances service offering
  • xs_template: parent cloud nested XenServer HV template
  • esxi_service_offering: parent cloud nested ESXi instances service offering
  • esxi_template: parent cloud nested ESXi HV template
  • vc_service_offering: parent cloud nested VC instances service offering
  • vc_template: parent cloud nested VirtualCentre template
  • baseurl_cloudstack: URL for CloudStack build repository
  • env_db_name: environments database name
  • env_db_ip: environments database IP address
  • env_db_user: environments database username
  • env_db_password: environments database password
  • env_zonetype: basic or advanced (default)
  • env_prihost: primary storage host fqdn or IP address
  • env_sechost: secondary storage host fqdn or IP address
  • env_zone_systemplate: URL to system template, overrides version variable
  • build_marvin: whether or not to build a marvin vm for testing purposes (default is false)
  • wait_till_setup: only return once system VMs are running. (default is no)

Some example --extra-args:

  • env_name=ccs-xs-13-patest env_version=cs45 mgmt=1 hvtype=x hv=2 xs_ver=xs65sp1 env_accounts=all pri=1 build_marvin=true mgmt_os=6
  • env_name=cs49-vmw55-pga env_version=cs49 mgmt_os=6 hvtype=v vmware_ver=55u3 hv=2 pri=2 env_accounts=all build_marvin=true wait_till_setup=yes baseurl_cloudstack=http://10.2.0.4/shapeblue/cloudstack/testing/
  • env_name=cs49-kvm6-pga env_version=cs49 mgmt_os=6 env_accounts=all hvtype=k kvm_os=6 hv=2 pri=2 env_accounts=all build_marvin=true wait_till_setup=yes baseurl_cloudstack=http://10.2.0.4/shapeblue/cloudstack/testing/
