# PowerShell script to provision a Windows Server with BuildKite
|
|
# This script follows https://buildkite.com/docs/agent/v3/windows.
|
|
|
|
# Instructions
|
|
|
|
# VM creation:
|
|
# In Google Cloud Platform, create a Compute Engine instance.
|
|
# We recommend machine type n1-standard-16 (16 vCPUs, 60 GB memory).
|
|
# Use a recent windows boot disk with container support such as
|
|
# "Windows Server version 1803 Datacenter Core for Containers", and add a 128GB SSD disk.
|
|
# Give it a name, then click "Create".
|
|
|
|
# VM setup:
|
|
# In the Compute Engine menu, select "VM Instances". Click on the VM name you chose before.
|
|
# Click "Set Windows Password" to choose a username and password.
|
|
# Click RDP to open a remote desktop via browser, using the username and password.
|
|
# In the Windows command prompt start an elevated powershell by inputing
|
|
# "powershell -Command "Start-Process PowerShell -Verb RunAs" followed by Enter.
|
|
# Download and execute this script from GitHub, passing the token (mandatory), tags (optional)
|
|
# and number of agents (optional) as args:
|
|
# ```
|
|
# Invoke-WebRequest -Uri https://raw.githubusercontent.com/angular/angular/master/.buildkite/provision-windows-buildkite.ps1 -OutFile provision.ps1
|
|
# .\provision.ps1 -token "MY_TOKEN" -tags "windows=true,another_tag=true" -agents 4
|
|
# ```
|
|
# The VM should restart and be fully configured.
|
|
|
|
# Creating extra VMs
|
|
# You can create an image of the current VM by following the instructions below.
|
|
# https://cloud.google.com/compute/docs/instances/windows/creating-windows-os-image
|
|
# Then create a new VM and choose "Custom images".
|
|
|
|
|
|
# Script proper.
|
|
|
|
# Get the token and tags from arguments.
