Jenkins : Orka by MacStadium

This is a Jenkins plugin to support both permanent and ephemeral Jenkins agents on Orka by MacStadium.

Prerequisites

  • Orka by MacStadium environment - Used to deploy new VMs used as Jenkins agents.
  • VPN connection to the Orka environment - Each Orka environment is behind a firewall. Your Jenkins master must have visibility to the environment.

Permanent Agents

The plugin allows you to create permanent agents, running on Orka by MacStadium. The plugin first deploys a new VM in an Orka environment and then uses SSH to connect to it.

Usage

To create a permanent agent go to Manage Jenkins → Manage Nodes and select New Node.

Provide a Node name and select Agent running under Orka by MacStadium.

Finally, click OK.










Next, configure the agent you want to launch and click OK.

Provide values for the following Orka properties:

  • Orka Credentials - The credentials used to connect to the Orka environment. Created by running orka user create.
  • Orka Endpoint - The endpoint used by the plugin to connect to the Orka environment.
  • Node - The Orka node which the agent will be deployed on.
  • VM (Optional) - The VM to be deployed. The field is inactive if Create a new VM Config is selected.
  • Create a new VM config (Optional) - Tells the plugin to create a new VM config and deploy it as an agent.
    • Config name (Optional) - The name of the new config. The field is inactive if Create a new VM Config is not selected.
    • Base Image (Optional)  - The base image of the new config. The field is inactive if Create a new VM Config is not selected.
    • Image (Optional) - The image of the new config. The field is inactive if Create a new VM Config is not selected.
    • # of CPUs (Optional) - The number of CPUs of the new config. The field is inactive if Create a new VM Config is not selected.
  • VM Credentials - The credentials used to SSH to the deployed VM.

Ephemeral Agents

The plugin allows Jenkins to create ephemeral agents, running on Orka by MacStadium. The plugin first deploys a new VM in an Orka environment and then uses SSH to connect to it.   

A new agent is automatically created by Jenkins if the build load is too high and there are no available executors. Once the VM has been idle for a given amount of time, Jenkins terminates it automatically and all resources are cleaned up.

Usage

To configure go to Manage Jenkins → Configure System and find Add a new cloud.

Select Orka Cloud.

Next, configure the cloud by providing values for:

  • Name of this Cloud - The name of the cloud.
  • Orka Credentials - The credentials used to connect to the Orka environment. Created by running orka user create.
  • Orka Endpoint - The endpoint used by the plugin to connect to the Orka environment.

Click Add Orka Template. An Orka template is the agent template, Jenkins will use to create a new agent.  

Fill the following values:

  • VM (Optional) - The VM to be deployed. The field is inactive if Create a new VM Config is selected.
  • Create a new VM config (Optional) - Tells the plugin to create a new VM config and deploy it as an agent.
    • Config name (Optional) - The name of the new config. The field is inactive if Create a new VM Config is not selected.
    • Base Image (Optional)  - The base image of the new config. The field is inactive if Create a new VM Config is not selected.
    • Image (Optional) - The image of the new config. The field is inactive if Create a new VM Config is not selected.
    • # of CPUs (Optional) - The number of CPUs of the new config. The field is inactive if Create a new VM Config is not selected.
  • VM Credentials - The credentials used to SSH to the deployed VM.
