Overview

Landscape client is the agent for the Landscape administration system.

Usage

This subordinate charm is intended to be used to register a machine against a running Landscape server. Configuration needs to be supplied or it won't do anything. Here is a simple config.yaml to register against the hosted version of Landscape:

landscape-client:
    account-name: <account_name_here>
    registration-key: <registration_key_here>
    tags: <csv_tag_list>

The following is a version if you need to customize the communication URL in case you are running against a dedicated version of Landscape (LDS). This version also sets Script exection, and allows landscape to become any user (even root), to execute scripts:

landscape-client:
    account-name: standalone
    registration-key: 128-qosk-7382
    tags: laptop,xenial,developer
    ping-url: http://landscape.example.com/ping
    url: https://landscape.example.com/message-system
    script-users: ALL
    include-manager-plugins: ScriptExecution

Configuration

Landscape client has a number of configuration options available allowing customizability into a variety of environments where resources may be scarce or security may be a concern. The most useful and common options are documented below.

To get more detail on options, these correlate directly to configuration settings on landscape-client itself. (landscape-client(1), landscape-client --help)

account-name: Name of the account to register against in the hosted version of Landscape. In the dedicated version of Landscape (LDS), this will always be "standalone"

registration-key: The account registration key, found in the Landscape account GUI.

tags:Comma separated list of tags to apply to the computer once it is registered.

url: The server url to connect to, will usually be https and end with /message-system

ping-url: If the server url is specified, ping-url should also be specified. Will usually be http and end with /ping

include-manager-plugins: This option is primarily used to enable the ScriptExecution plugin, which allows arbitrary scripts to be executed on the registered computer.

script-users: Comma-separated list of users that the landscape client can become to execute scripts. Keyword "ALL" can be used to include all users on the system.

ssl-public-key: If needed, use this to give the client the CA certificate it should use to verify the server certificate it is connecting to.

When registering the client against a server with a custom or not well known CA, you will need to use the ssl-public-key option. To insert the certificate contents into the charm config directly, just encode it in base64.

For example, let's assume ca.pem is a file with the CA certificate the client needs to use to verify the server:

cat ca.pem | openssl base64 -e > ca.encoded

Now insert the ca.encoded contents into the charm config, like this:

landscape-client:
    url: ....
    ping-url: ....
    ssl-public-key: |
        base64:<insert-here-
        contents-of-ca.encoded>...
        ...
        ...
