Upgrade Windows infrastructure

Last updated on

Run the commands in PowerShell as Administrator on the VM where the Windows chaos infrastructure is installed.

Uninstall the current version​

Replace 1.55.0 with the version currently installed:

powershell -Command "& { Invoke-WebRequest -Uri 'https://app.harness.io/public/shared/tools/chaos/windows/1.55.0/uninstall.ps1' -OutFile 'uninstall.ps1' -UseBasicParsing; .\uninstall.ps1 }"
Capture the service account

Note the account that runs the WindowsChaosInfrastructure service before uninstalling. You need the same credentials in the install step.

Install the new version​

Replace 1.56.0 with the target version, and supply the captured admin credentials, infraID, and access key (both readable from C:\HCE\config.yaml):

powershell -Command "& { Invoke-WebRequest -Uri 'https://app.harness.io/public/shared/tools/chaos/windows/1.56.0/install.ps1' -OutFile 'install.ps1' -UseBasicParsing; .\install.ps1 -AdminUser '.\<your-account-username>' -AdminPass '<your-account-password>' -InfraId '<infra-id>' -AccessKey '<access-key>' -ServerUrl 'https://app.harness.io/gratis/chaos/mserver/api' }"

Notes:

  • .\ in AdminUser indicates a local account. For a domain account, replace it with the domain.
  • If the VM is behind a proxy, append -HttpsProxy <proxy> -HttpProxy <proxy> -NoProxy <bypass> to the install command.
