This chapter describes how to install Cisco Elastic Services Controller on CSP 2100 and includes the following sections:

Prerequisites

Following are the prerequisites that you require before you start installing the ESC instance in CSP 2100.

  • Virtual CPUs 4 (minimum)

  • Memory 8 GB

  • Disk size 30 GB

Installing the Elastic Services Controller Instance in CSP 2100

Once you have completed the tasks specified in the prerequisites section, you can use the following procedure to deploy and launch ESC instance in CSP 2100. Following are the three deployment alternatives available for CSP 2100.

  • ESC with Single and Dual Interfaces

  • ESC HA Active/Standby Installation

For list of variables used in the CSP 2100 sample files, see List of Variables Used in CSP 2100 Sample Files.

ESC with Single and Dual Interface

To install ESC in CSP, you must create the user-data in the following format as the day0 configuration file:

A sample for single interface describing the day zero file as config drive and user data is as follows:

#cloud-config
users:
 - name: admin          # The user's login name
   gecos: admin         # The user name's real name
   groups: esc-user     # add admin to group esc-user
   passwd: $6$saltsalt$9PDBehueUG4XTLEj6BFZA5MDGh/XeQ6QPbf9HYLU3RifHj1
                        # The hash -- not the password itself -- of the password you want
                        #           to use for this user. You can generate a safe hash via:
                        #               mkpasswd --method=SHA-512 --rounds=4096
   lock-passwd: false   # Defaults to true. Lock the password to disable password login
                        # Set to false if you want to password login
   homedir: /home/admin # Optional. Set to the local path you want to use. Defaults to /home/<username>
   sudo: ALL=(ALL) ALL  # Defaults to none. Set to the sudo string you want to use

ssh_pwauth: True        # Defaults to False. Set to True if you want to enable password authentication for sshd.

Creating ESC passwords to use in Day0 Files

When using the Cloud-Init day0 file to deploy an ESC instance, the passwords must be passed in as a hash, and not a plain text.

To create a hashed password, use the mkpasswd tool. The following example shows how to use the mkpasswd tool to create a hashed password. 

~$ mkpasswd --method=SHA-512 --rounds=4096
Password:
$6$rounds=4096$Yo11pRsFO$iT5SGMJ6z8WEnmj8TKMdInblgWeb/UChmrsQs3aspx8j.yUuuhxKk2XScOkerWWxpqD5F0sLfC5kzT5t2xGkL1

Procedure

Step 1

Upload user-data file to CSP

To deploy ESC, the user-data file must be first uploaded to the CSP node.

Note 

The path to upload images and day0 files is: /osp/repository

 
scp user-data-esc admin@<CSP_IP_ADDRESS>:/osp/repository
Step 2

Deploying ESC VM

You must edit configuration to be sent to the CSP node hosting the ESC VM.

Following is the deployment datamodel for single interface. For dual interface, you have two interfaces.<name>ESC-SA-2-IF</name>

<?xml version="1.0"?>
<services xmlns="http://www.cisco.com/ns/test/service">
  <service>
    <name>VAR_SERVICE_NAME</name>
    <memory>8192</memory> <!-- minimum 8G -->
    <numcpu>4</numcpu> <!-- minimum 4 -->
    <disk_size>30.0</disk_size> <!-- minimum 30G -->
    <disk-resize>true</disk-resize>
    <iso_name>ESC-5_0_0_xxx</iso_name> <!-- the name of the ESC image already on the CSP -->
    <power>on</power>
    <ip>172.20.117.40</ip>
    <!-- add the ip for display in the CSP web/console interfaces -->
    <vnc_password>password1</vnc_password>
    <!-- to secure the VNC console session -->
    <vnics>
      <!-- This interface aligns with eth0 in the user-data file -->
      <vnic>
        <nic>0</nic>
        <vlan>1</vlan>
        <tagged>false</tagged>
        <type>access</type>
        <passthrough_mode>none</passthrough_mode>
        <model>virtio</model>
        <network_name>VAR_NETWORK0_NAME</network_name>
      </vnic>
      <!-- This interface aligns with eth1 in the user-data file -->
      <!-- If not using 2 interfaces, this vnic block can be removed -->
      <vnic>
        <nic>1</nic>       
        <vlan>1</vlan>
        <tagged>false</tagged>
        <type>access</type>
        <passthrough_mode>none</passthrough_mode>
        <model>virtio</model>
        <network_name>VAR_NETWORK1_NAME</network_name>
      </vnic>
    </vnics>
    <disk_type>ide</disk_type>
    <day0_filename>user-data-esc</day0_filename> <!-- this name MUST match the name of the file that was copied to the CSP -->
    <day0-dest-filename>user-data</day0-dest-filename>  <!-- mandatory value -->
    <day0-volume-id>cidata</day0-volume-id>  <!-- mandatory value -->
  </service>
</services>
Step 3

Sending Configuration

Use a netconf-console (shipped with ConfD) to deploy ESC on a CSP node.

$ netconf-console --port=2022 --host=<CSP_IP_ADDRESS> --user=CSP_ADMIN_USERNAME --password=CSP_ADMIN_PASSWORD --edit-config=deployESCHA1.xml

If HA, repeat the command with the configuration for the second ESC.
Step 4

Configuring the VIM Connector

After ESC has booted, configure the VIM Connectors.

When installing ESC in CSP, no VIM connectors are added by default. To manage VNFs, you must create the VIM connector.
Step 5

Adding the VIM Connectors

For more information on configuring VIM connectors after installation, and managing VIM connectors, see Managing VIM Connectors in the Cisco Elastic Services Controller User Guide.

ESC HA Active/Standby Installation

To install ESC in CSP, you must create the user-data in the following format as the day0 configuration file. For HA, you must define one file for each VM.

For creating ESC passwords to use in Day0 Files, see the Creating ESC passwords to use in Day0 Files section.

A sample for ESC HA Active/Standby installation on node 1 describing the day zero file as config drive and user data is as follows: 

user-data sample - HA Node 1

Procedure

Step 1

Uploading user-data file to CSP

To deploy ESC, the user-data file must be first uploaded to the CSP node.

Note 

The path to upload images and day0 files is: /osp/repository

 
scp user-data-esc-ha-1 CSP_ADMIN_USERNAME@<CSP_IP_ADDRESS>:/osp/repository

scp user-data-esc-ha-2 CSP_ADMIN_USERNAME@<CSP_IP_ADDRESS>:/osp/repository
Step 2

</services>
Step 3

Sending Configuration

Use a netconf-console (shipped with ConfD) to deploy ESC on a CSP node.

$ netconf-console --port=2022 --host=<CSP_IP_ADDRESS> --user=<CSP_ADMIN_USERNAME> --password=<CSP_ADMIN_PASSWORD> --edit-config=deployESC-HA-1.xml

$ netconf-console --port=2022 --host=<CSP_IP_ADDRESS> --user=<CSP_ADMIN_USERNAME> --password=<CSP_ADMIN_PASSWORD> --edit-config=deployESC-HA-2.xml
Step 4

Configuring the VIM Connector

After ESC has booted, configure the VIM Connectors.

When installing ESC in CSP, no VIM connectors are added by default. To manage VNFs, you must create the VIM connector.
Step 5

Adding the VIM Connectors

For more information on configuring VIM connectors after installation, and managing VIM connectors, see Managing VIM Connectors in the Cisco Elastic Services Controller User Guide.

List of Variables Used in CSP 2100 Sample Files
