This is a demo appliance for VirtualBox (in OVA format) that has X11 and Plasma 5 enabled, as well as the VirtualBox guest additions. To use it, download the OVA file, open VirtualBox, run “File → Import Appliance” from the menu, select the OVA file, and click “Import”. You can then start the virtual machine. When the KDE login screen appears, you can log in as user demo, password demo. To obtain a root shell, run sudo -i in the KDE terminal (konsole).

• VirtualBox appliance, 64-bit Intel/AMD (SHA-256)

If you are an EC2 user, you can fire up a NixOS instance instantly by using one of the AMIs listed below.

You can create an instance using the AWS Management Console by clicking one of the Launch buttons. You can also create an instance from the command line. For example, to create an instance in region eu-west-1 using the EC2 API tools, just run:

        $ ec2-run-instances  --region eu-west-1 -k my-key-pair

If you are an Azure user, you can manually create a NixOS instance by using one of the bootstrap BLOBs listed below.

You can create an instance from the command line. For example, to create an instance of version 19.09 of NixOS using azure-cli, just run:

# settings
# vm name must be lowercase and letters/numbers only because it's also used as the domain name
export VM_NAME="nixosvm"
export RESOURCE_GROUP="rg-nixosvm"
export LOCATION="eastus"
export STORAGE_ACCOUNT="nixosvm"
export SOURCE_URI=""

# create group
az group create \
    --name "$RESOURCE_GROUP" \
    --location "$LOCATION

# create storage
az storage account create \
    --name "$STORAGE_ACCOUNT" \
    --group "$RESOURCE_GROUP" \
    --location "$LOCATION" \
    --sku Standard_LRS

az storage account keys list \
    --name "$STORAGE_ACCOUNT" \
    --group $RESOURCE_GROUP

# export one of the storage access keys
export STORAGE_ACCOUNT_KEY="..."
echo $STORAGE_ACCOUNT_KEY

az storage container create \
    --account-name "$STORAGE_ACCOUNT"
    --account-key "$STORAGE_ACCOUNT_KEY"
    --name vm-images

If you are Google Cloud Platform user, you can create a NixOS image using one of the raw disks listed below. You can then create a NixOS instance using the image.

For example:

image=my-nixos-image
source_uri=https://storage.googleapis.com/nixos-cloud-images/nixos-image-18.09.1228.a4c4cbb613c-x86_64-linux.raw.tar.gz
source_uri=$(sed 's%gs:/%https://storage.googleapis.com%' <<< $source_uri)
gcloud compute images create $image --source-uri=$source_uri
gcloud compute instances create instance-1 --image=$image

Unstable releases

If you are a developer who wants to contribute to NixOS, or if you just want the latest and greatest, you can also install the most recent unstable release.
