So far in this series we have looked at creating asset
within the
EMOC BUI but
the Exalogic 2.0.1 installation also provide
the Iaas
cli as an alternative to most of
the common functionality
available
within EMOC.
The IaaS cli interface provides access to
the functions that are available to a user logged into
the BUI
with
the CloudUser Role.
As such not all functionality is available from
the command line
interface however having said that
the IaaS cli provides all
the
functionality required to create
the Assets
within a specific
Account (Tenure). Because these action are common and repeatable I
decided to wrap
the functionality
within a simple script that
takes a simple input file and creates
the Asset.
Following
the Script through will show us
the required steps
needed to create
the various Assets
within an Account and hence I
will work through
the various functions
within the script below
describing
the steps.
You will note from
the various steps
within the script that it is
designed to pause between actions allowing
the proceeding action
to complete.
The reason for this is because we could swamp EMOC
with a series of actions and may end up with a situation where we
are trying to action a Volume attached before
the creation of
the
vServer and Volume have completed.
processAssets()
This function simply reads through
the passed input file
identifying what assets need to be created. An example of
the
input file can be found below. It can be seen that
the input file
can be used to create Assets in multiple Accounts during a single
run.
The order of
the entries define
the functions that need to be
actioned as follows:
Input Command
Iaas Actions
Parameters
Production:Connect
akm-describe-accounts
akm-create-access-key
iaas-create-key-pair
iaas-describe-vnets
iaas-describe-vserver-types
iaas-describe-server-templates
Username
Password
Production:Create|vServer
iaas-run-vserver
vServer Name
vServer Type Name
Template Name
Comma separated list of network names which
the
vServer will connect to.
Comma separated list of IPs for
the specified
networks.
Production:Create|Volume
iaas-create-volume
Volume Name
Volume Size
Production:Attach|Volume
iaas-attach-volumes-to-vserver
vServer Name
Comma separated list of volume names
Production:Disconnect
iaas-delete-key-pair
akm-delete-access-key
None
connectToAccount()
It can be seen from
the connectToAccount function that before we
can execute any Asset creation we must first connect to
the
appropriate account. To do this we will need
the ID associated
with
the Account. This can be found by executing
the
akm-describe-accounts cli command which will return a list of all
Accounts and there IDs. Once we have
the Account ID we generate
and Access key using
the akm-create-access-key command and then a
keypair with
the iaas-create-key-pair command.
At this point we now have all
the information we need to access
the specific named account.
createVServer()
This function simply retrieved
the information from
the input
line and then will create
the vServer using
the iaas-run-vserver
cli command. Reading
the function you will notice that it takes
the various input names for vServer Type, Template and Networks
and converts them into
the appropriate IDs.
The IaaS cli will not
work directly with component names and hence all IDs need to be
found.
createVolume()
Function that simply takes
the Volume name and Size then executes
the iaas-create-volume command to create
the volume.
attachVolume()
Takes
the name of
the Volume, which we may have just created, and
a Volume then identifies
the appropriate IDs before assigning
the
Volume to
the vServer with
the iaas-attach-volumes-to-vserver.
disconnectFromAccount()
Once we have finished connecting to
the Account we simply remove
the key pair with iaas-delete-key-pair and
the access key with
akm-delete-access-key although it may be useful to keep this if
ssh is required and you do not subsequently modify
the sshd
information to allow unsecured access. By default
the key is
required for ssh access when a vServer is created from
the
command-line.
