FsCloudInit

Create cloud-init VM configuration files in F#.

Examples

Installing the dotnet 5.0 SDK on a VM. This pulls the Microsoft package source and signing key when building the cloud-init configuration.

async {
    // curl -sSL https://packages.microsoft.com/config/ubuntu/18.04/prod.list | sudo tee /etc/apt/sources.list.d/microsoft-prod.list
    let! aptSourceRes = http.GetAsync "https://packages.microsoft.com/config/ubuntu/18.04/prod.list" |> Async.AwaitTask
    let! aptSource = aptSourceRes.Content.ReadAsStringAsync () |> Async.AwaitTask
    // curl -sSL https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
    let! gpgKeyRes = http.GetAsync "https://packages.microsoft.com/keys/microsoft.asc" |> Async.AwaitTask
    let! gpgKey = gpgKeyRes.Content.ReadAsStringAsync () |> Async.AwaitTask
    {
        CloudConfig.Default with
            Apt =
                Apt (
                    Sources =
                        dict [
                            "microsoft-prod", { AptSource.Default with Key = gpgKey; Source = aptSource}
                        ]
                ) |> Some
            PackageUpdate = Some true
            Packages = [
                Package "apt-transport-https"
                PackageVersion (PackageName="dotnet-sdk-5.0", PackageVersion="5.0.103-1")
            ]
    }
    |> Writer.write
    |> Console.WriteLine
}

The above snippet writes a cloud-init configuration file to the console, resulting in the following configuration file that can be used to install the SDK on a server:

#cloud-config           
apt:
  sources:
    microsoft-prod:
      key: >
