Command-Line Interface (CLI)¶
All DPBuddy commands have the following format:
dpbuddy <command> <options>
“command” is any of the commands/tasks described in the document. The command (or -h
) must be the first argument.
In this document the words “task” and “command” are used interchangeably. Every DPBuddy command has a corresponding Ant task with the same name.
The options for every command are listed under “Options/Attributes”. Each option must be preceded by -
. In this document, “option” and “attribute” are also used interchangeably; every command line option has a corresponding Ant attribute and vice versa.
For example, the import
command supports the file
option. To run the command, type
dpbuddy import -file domain.zip
The value is optional for Boolean options. The Boolean options always default to true
. For example, to run import
in the dry-run mode, supply -dry-run
option:
dpbuddy import -file domain.zip -dry-run
This is equivalent to:
dpbuddy import -file domain.zip -dry-run true
You can also provide explicit false
value:
dpbuddy import -file domain.zip -dry-run false
All commands support the -h
option, which displays the list of all supported options and their descriptions, e.g., dpbuddy import -h
.
There are several other options that are common to all DPBuddy commands. All these options are listed in Common Options and Properties. For example, to specify a DataPower domain, you can run the import
command with the -domain
option:
dpbuddy import -file domain.zip -domain my-domain
You can specify the default value for any common option in a configuration file. In addition, configuration file can contain environment-dependent values. DPBuddy supports two different formats for defining configuration: HOCON and name=value properties. HOCON files have “.conf” extension and properties files have “.properties” extension. The default name of the configuration file is dpbuddy.conf or dpbuddy.properties.
DPBuddy follows these steps to locate and load the configuration file:
If the
-confFile
command-line option is specified, DPBuddy will use the value of this option as the path to the configuration file. This is a full path that includes the name of the file.If the
DPBUDDY_CONFIG
environment variable is specified, DPBuddy will use the value of this variable as the path to the configuration file. This is a full path that includes the name of the file.DPBuddy will attempt to load the file
dpbuddy.conf
from the$DPBUDDY_HOME/conf
directory.DPBuddy will attempt to load the file
dpbuddy.conf
from the current directory (the directory where the command is run).DPBuddy will attempt to load the file
dpbuddy.conf
from the user’s home directory using the path<home>/.dpbuddy/dpbuddy.conf
.DPBuddy will attempt to load the file
dpbuddy.conf
from “/etc”.If
dpbuddy.conf
is not found, DPBuddy will repeat the last three steps for namedpbuddy.properties
.If neither file is found, DPBuddy will print a warning message.
DPBuddy uses Apache Commons Configuration to parse the properties configuration file. Commons Configuration’s format supports many advanced features, including variable interpolation. This means that a property in the configuration file can reference another property’s value using ${}
notation.
${}
can also be used directly on the command line as an option’s value:
dpbuddy import -file "\${import.file.path}"
In this example import.file.path
is the property defined in the configuration file. Note that $
must be escaped using \$
on Linux to prevent the shell from treating it as a shell variable.
DPBuddy pre-populates all built-in Ant properties and Java system properties, so any of these properties can be used on the command line or in the configuration file:
dpbuddy tailLog -lines "-1" -logFile "\${java.io.tmpdir}/dp.log" -appendTimestamp
You can also set properties using the environment variable DPBUDDY_OPTS
and -D
Java option:
set DPBUDDY_OPTS=-Xmx1024m -Ddev.dp.host=myDPHost
You can also split your DPBuddy configuration into multiple files and use HOCON includes or property files includes to create a master file, e.g., include=another_config.properties
.
You can use the sample configuration file included in the distribution under samples/cli-shell
and samples/cli-win
as the starting point for your DPBuddy configuration file.
Once your configuration and your environments are defined, you can point DPBuddy to a specific environment using the -env
option:
dpbuddy import -file domain.zip -env dev
You can also use the exportConf command to save configuration for a particular environment as a shell/batch file (i.e., each environment configuration property is translated into a shell variable). This file can then be sourced from other scripts thus providing convenient access to the environment configuration from any shell command.
