Worker Model vSphere

CDS build using vSphere infrastructure

Add vSphere worker model

We need to define a vSphere worker model to have vSphere hatchery booting workers.

We will create a worker model called debian8-docker:

On Debian 8
With Docker ready to use
Git installed

You need to configure:

The image is the name of your virtual machine that you have created before on your host to clone (See Advanced)
Pattern If you aren’t an administrator you have to choose a configuration pattern in order to fill pre command, worker command and post command with a pattern that an administrator have already fill for you.
If you are an administrator:
- pre worker command: all scripts that need to be run before execute the worker binary (for example: set the right environment variables, install curl and other tools you need like Docker, …)
- main worker command: the command launched to run the worker with right flags thanks to the interpolate variables that CDS fill for you (more information click here).
- post worker command: the command launched after the execution of your worker. If you need to clean something and then shutdown the VM.

Via UI (inside settings section –> worker models):

For example:

Or via CLI with a yaml file:

$ cds worker model import my_worker_model.yml

name: testvsphere
type: vsphere
description: "my worker model"
group: shared.infra
image: debian8
