jenkins-node-ssh

Setup the host as a Jenkins SSH node and connect the Jenkins master to it. This is the preferred method of connecting a node to the Jenkins master as the master initiates the connections and can reconnect easily.

For information about PTA and how to use it with this Ansible role please visit https://github.com/Forcepoint/fp-pta-overview/blob/master/README.md

Requirements

The Jenkins master already exists, basic setup is complete, and the credential object for SSH node connections exists.

Role Variables

REQUIRED

• jenkins_node_master_url: The URL to the Jenkins master this node will connect with.
• jenkins_node_master_user: A user on the Jenkins master that has enough permissions to add a node.
• jenkins_node_master_password: The password for the user on the Jenkins master. This should be vaulted.
• jenkins_node_credential: The ID of a credential object which has the user 'jenkins' and associated password which will be used to connect from the master to the node over SSH
• jenkins_node_user_password: The password for the 'jenkins' user to be created on the node.

Make sure you get those passwords vaulted so they're not in plain text!

OPTIONAL

• jenkins_node_name: The name for the node. This defaults to the ansible host name.
• jenkins_node_description: The description for the node. The default is blank.
• jenkins_node_executors: The number of executors for the node. This defaults to 1.
• jenkins_node_labels: The labels to apply for the node. Multiple labels should be separated by a space. This defaults to the ansible host name.
• jenkins_node_host: The DNS/IP address for the node. This defaults to the ansible host's default IPV4 address.
• jenkins_node_master_ca_cert: The path to the CA certificate for verifying SSL connections with the master, if needed.
• jenkins_node_user: The user name for connecting to this Jenkins instance.
• jenkins_node_user_groups: Specify the groups the the jenkins user should be in. Useful for adding the user to groups (like docker) that get setup by other ansible roles (like docker-host).
• jenkins_node_openjdk_major_version: The major version of OpenJDK to install. This defaults to the same major version that the jenkins master role uses.
• jenkins_node_openjdk_full_version: The full version of OpenJDK to install. Defaults to "latest" but you can provide a specific version if you like. EX: "11.0.6.10"
• jenkins_node_pip_packages: Install additional pip packages needed to fulfill the purpose assigned for this node.

Dependencies
