Run tasks

Sections

Run ad hoc tasks on target nodes to upgrade packages, restart services, execute shell commands, or perform any other type of single-action executions on your nodes.

Tasks are similar to scripts, but they are kept in modules and can have metadata. For more information, see Bolt tasks.

When selecting to run a task from either a details or listing page, some of the selected nodes might not be eligible to run the task on. An eligible node must be accessible using the SSH or WinRM credentials you added, or if running the install Puppet agent task, an eligible node doesn't have the agent installed.

  1. On the sidebar, click Run tasks, and select the task:
    • Install Puppet agent.
    • Run a shell command.
    • Manage package.
    • Manage service.
  2. Enter the values for the task parameters (see below).
  3. Click Select nodes.
  4. Select the nodes to run the task on, and click Select credentials.
  5. Select the credentials for accessing the hosts, and click Review task summary.
  6. Review the tasks details, your credentials, the list of target nodes, and click Run task.
    Tip: To view the status of the task run, on the left hand pane, click Latest events.

Installing Puppet agents

Install a Puppet Enterprise agent to regularly pull configuration catalogs from a Puppet master, and apply them to your target Linux or Windows nodes. The agent maintains the node configuration you want.

Although Puppet Remediate is not integrated with Puppet or Puppet Enterprise, and you do not need to have Puppet or Puppet Enterprise installed to use Remediate, you can use Remediate to install a Puppet Enterprise agent to work with a Puppet master.

Parameter Description
cacert_content The master CA certificate content (optional). If not specified, the master's identity is not verified during the agent installation.
certname The unique certificate name for the Puppet agent (optional).
custom_attribute The custom attribute setting added to puppet.conf and included in the custom_attributes section of csr_attributes.yaml.
Important: Values must be entered as an array.
dns_alt_names The alternative DNS names for generating the agent certificate.
environment The environment to install with the Puppet agent (optional).
extension_request The extension attribute setting added to puppet.conf and included in the extension_requests section of csr_attributes.yaml.
Important: Values must be entered as an array.
master The required hostname for the Puppet master. The FQDN must be fully resolvable by the node on which you're installing the agent.
Comment Any comments that provide context to this action.

Running shell commands

Execute an arbitrary shell command on discovered nodes without installing an agent.

Note: If you are using Remediate on Linux, the Remediate user must be added without a password to the /etc/sudoers file and configured to not require a tty. For example:
Defaults:myuser !requiretty
Parameter Description
command The command to execute on the target nodes.

Linux example:

echo "Hello, World ${USER}" > /hello.txt

Windows example:

echo "Hello, World $env:UserName" > C:\hello.txt

To execute commands, Windows tasks use the command prompt. To run PowerShell commands, you must invoke PowerShell. For example:

powershell Get-Process
failonfail By default, the task fails when the command returns a non-zero. To disable this default setting, select the checkbox.
interleave By default, content from stdout and stderr is interleaved. To disable this default setting, select the checkbox.

Managing packages

Install, upgrade, or uninstall packages on discovered nodes without installing an agent.

Remember:

To run the manage package task on target hosts, the following package management systems are required:

  • APT or YUM for Linux hosts.

  • Chocolatey for Windows hosts.

Parameter Description
Action The action to be applied to the package
  • install the package. To install a specific version of the package, specify the value in the version parameter. If installing the package for the first time, the package repository on each target node must have the package stored.
  • status of the package. Whether the package is currently installed or not.
    Note: Status is only available for Linux packages.
  • uninstall the package. To uninstall a specific version of the package, specify the value in the version parameter.
  • upgrade the version of the package. This is particularly useful for upgrading vulnerable packages to secure versions. To upgrade to a specific version, choose install, and specify the value in the version parameter.
Name The name of the package.
Provider The name of the provider to use for managing or inspecting the package.
Version The version, and if applicable, the release value of the package. A version number range or a semver pattern are not permitted. For example, to install the bash-4.1.2-29.el6.x86_64.rpm package, enter 4.1.2-29.el6.
Tip: To install or upgrade to the latest version of a package, leave the version parameter blank.

Managing system services

Parameter Description
Action The action to be applied to the service:
  • stop the service.

  • start the service.

  • restart the service.

  • enable the service.

  • disable the service.

  • View the current status of the service (Windows only).

Name The name of the service.
