This is a Node Step Job plugin that sends commands to a remote node via SSH. The commands occur in the same SSH channel, and therefore share state. This is particularly useful for network devices (see example below) or for compute resources when certain commands can strictly be executed from a particular working directory or with certain environment variables set.
Run the following command to build the jar file (using Java 1.8):
gradle build
Alternatively download the latest released Jar from the Releases Page
Copy the sequential-commands-plugin-x.y.x.jar file to the $RDECK_BASE/libext/ directory inside your Rundeck installation.
Or you can upload the file through the GUI as described here.
The plugin makes use of SSH credentials that are set on the nodes in Rundeck. If the ssh-password-storage-path attribute is set, then the plugin will authenticate using the SSH password, otherwise it will use the ssh-key-storage-path attribute.
To add a command to the Job Step, click on Add Custom Field:
In the configuration popup, set the field Field Label and Field Key. Inputs here do not influence the command that is sent to the remote node - they serve to identify the commands within the Job Step. Optionally set the Description field:
This then adds a field within the Job Step where you can input a command that you want to send to the remote node. Continue to add Custom Fields to the Job step such that you can send multiple commands to the node in a single SSH channel. Commands are sent to the remote node in sequential order.
As an example, in the screenshot below, the order of commands send to the remote node would be: enable, then a secure-job-option containing the enable password is sent to the device (this will not be shown in the logs output), this is then followed by the terminal length 0 command and then finally the show interfaces command.
You can view and download this example job here.
The output for this example (on a Cisco CSR) would appear like so:
Optionally select the Strict Host Key Checking checkbox to choose whether or not Rundeck checks that the remote-node is in the known_hosts file.
