Use cases

Petals CLI realizes the following use-cases.

Petals CLI capabilities about script and shell usages

Interactive console

Launching the Petals CLI with the following command line starts an interactive console with a prompt where the user can enter commands:

> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli>

This command is wrapped by another shell: petals-cli-console.sh

Execution of a Petals CLI command directly on the command line

Launching the Petals CLI with the following command line executes the command specified on the command line:

> ./petals-cli.sh -c <command> <command-args>

Execution of a Petals script file

Launching the Petals CLI with the following command line executes commands of a Petals script:

> ./petals-cli.sh -f <filename>

A Petals script is text file containing command supported by Petals CLI.

Execution of an inlined Petals script

Launching the Petals CLI with the following command line executes commands provided through the 'stdin':

> cat <filename> | ./petals-cli.sh -f -
> ./petals-cli.sh -f - << EOF
<command1> <command1-args>
<command2> <command2-args>
EOF

Connection to a Petals node

Connection options from the command line

All parameters needed to a JMX connection to a remote Petals node must be configurable on the command line as options:

> ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -c <command>
> ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -C
Conected on <host1>:<port1> with <user1>
petals-cli>

Interacting with several Petals node without exiting Petals CLI

In interactive mode or script mode, we should be able to close a connection and open another one without leaving Petals CLI. This is done by commands 'close' and 'open'. If no arguments are set on command 'open', default values (localhost:7700, login=petals, pwd=petals) are used:

> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> open <user1>:<password1>@<host1>:<port1>
Conected on <host1>:<port1> with '<user1>'
petals-cli> close
petals-cli> open
Conected on localhost:7700 with 'petals'

Default connection

By default (if no arguments or option are set):

• In mode 'console', the connexion is establish on command 'open' to localhost:7700 with credentials 'petals/petals',

  > ./petals-cli.sh -C
  
  Type 'help' for help.
  ------------------------------------------------------------------------------
  petals-cli> open
  Conected on localhost:7700 with 'petals'
  

• In mode 'command line', connexion parameter are mandatory

  > ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -c <command>
  

• In mode 'script', the connexion is establish on command 'open' to localhost:7700 with credentials 'petals/petals'

  > ./petals-cli.sh -f - << EOF
  open
  EOF
  

Petals CLI commands

Installation/Deployment of an artifact

Petals CLI is able to install/deploy and start a JBI artifact without distinction between shared-library, component and service assembly using the following command:

deploy <artifact-file> [<configuration-file> | <configuration-properties>]

where:

• <artifact-file> is the local file name or the URL of the artifact to install or deploy and start
• <configuration-file> is the local file name or the URL of the properties file used to configure the artifact. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with <configuration-properties>.
• <configuration-properties> is a list of '<property-name>=<property-value>', separated by space, where <property-name> is the name of the property to configure with <property-value>. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with <configuration-file>.
