Sample Release

This is a sample BOSH release than can be deployed using a Windows stemcell. It has a single job called say-hello that repeatedly prints out a message.

After creating a deployment with this release and the say-hello job you can access the job's standard out with the bosh log command (see documentation on logs for more information).

Release Structure

mkdir sample-windows-release
cd sample-windows-release
bosh init-release --git
bosh generate-job say-hello

jobs/
  say-hello/
    templates/
      post-deploy.ps1
      post-start.ps1
      pre-start.ps1
      start.ps1
    monit
    spec

spec

The spec file specifies the job name and description. It also contains the templates to render, which may depend on zero or more packages. See the documentation on job spec files for more information.

---
name: say-hello

description: "This is a simple job"

templates:
  start.ps1: bin/start.ps1

packages: []

monit

The monit file includes zero or more processes to run. Each process specifies an executable as well as any arguments and environment variables. See the documentation on monit files for more information. Note, however, that Windows monit files are JSON config files for Windows service wrapper, not config files for the monit Unix utility.

{
  "processes": [
    {
      "name": "say-hello",
      "executable": "powershell",
      "args": [ "/var/vcap/jobs/say-hello/bin/start.ps1" ],
      "env": {
        "FOO": "BAR"
      }
    }
  ]
}

start.ps1

The start.ps1 script executed by the service-wrapper loops indefintely while printing out a message:

while ($true)
{
  Write-Host "I am executing a BOSH job. FOO=${Env:FOO}"
  Start-Sleep 1.0
}

Creating and Deploying the Sample Release

If you have the Director with a Windows stemcell uploaded, you can create the above described release with an empty blobs.yml and final.yml, then try deploying it:

cd sample-windows-release
bosh create-release --force
bosh upload-release
bosh -d sample-windows-deployment deploy manifest.yml

For information about deployment basics, see the Deploy Workflow documenation.

Here is a sample manifest. For information on manifest basics, see the Deployment Manifest documentation.
