RemoteClaw

RemoteClaw on Azure Linux VM

This guide sets up an Azure Linux VM with the Azure CLI, applies Network Security Group (NSG) hardening, configures Azure Bastion for SSH access, and installs RemoteClaw.

What you will do

  • Create Azure networking (VNet, subnets, NSG) and compute resources with the Azure CLI
  • Apply Network Security Group rules so VM SSH is allowed only from Azure Bastion
  • Use Azure Bastion for SSH access (no public IP on the VM)
  • Install RemoteClaw with the installer script
  • Verify the Gateway

What you need

  • An Azure subscription with permission to create compute and network resources
  • Azure CLI installed (see Azure CLI install steps if needed)
  • An SSH key pair (the guide covers generating one if needed)
  • ~20-30 minutes

Configure deployment

```bash az login az extension add -n ssh ``` 
The `ssh` extension is required for Azure Bastion native SSH tunneling.
 ```bash az provider register --namespace Microsoft.Compute az provider register --namespace Microsoft.Network ``` 
Verify registration. Wait until both show `Registered`.


```bash
az provider show --namespace Microsoft.Compute --query registrationState -o tsv
az provider show --namespace Microsoft.Network --query registrationState -o tsv
```
 ```bash RG="rg-remoteclaw" LOCATION="westus2" VNET_NAME="vnet-remoteclaw" VNET_PREFIX="10.40.0.0/16" VM_SUBNET_NAME="snet-remoteclaw-vm" VM_SUBNET_PREFIX="10.40.2.0/24" BASTION_SUBNET_PREFIX="10.40.1.0/26" NSG_NAME="nsg-remoteclaw-vm" VM_NAME="vm-remoteclaw" ADMIN_USERNAME="remoteclaw" BASTION_NAME="bas-remoteclaw" BASTION_PIP_NAME="pip-remoteclaw-bastion" ``` 
Adjust names and CIDR ranges to fit your environment. The Bastion subnet must be at least `/26`.
 Use your existing public key if you have one: 
```bash
SSH_PUB_KEY="$(cat ~/.ssh/id_ed25519.pub)"
```


If you don't have an SSH key yet, generate one:


```bash
ssh-keygen -t ed25519 -a 100 -f ~/.ssh/id_ed25519 -C "you@example.com"
SSH_PUB_KEY="$(cat ~/.ssh/id_ed25519.pub)"
```
 ```bash VM_SIZE="Standard_B2as_v2" OS_DISK_SIZE_GB=64 ``` 
Choose a VM size and OS disk size available in your subscription and region:


- Start smaller for light usage and scale up later
- Use more vCPU/RAM/disk for heavier automation, more channels, or larger model/tool workloads
- If a VM size is unavailable in your region or subscription quota, pick the closest available SKU


List VM sizes available in your target region:


```bash
az vm list-skus --location "${LOCATION}" --resource-type virtualMachines -o table
```


Check your current vCPU and disk usage/quota:


```bash
az vm list-usage --location "${LOCATION}" -o table
```

Deploy Azure resources

```bash az group create -n "${RG}" -l "${LOCATION}" ``` Create the NSG and add rules so only the Bastion subnet can SSH into the VM. 
```bash
az network nsg create \
  -g "${RG}" -n "${NSG_NAME}" -l "${LOCATION}"


# Allow SSH from the Bastion subnet only
az network nsg rule create \
  -g "${RG}" --nsg-name "${NSG_NAME}" \
  -n AllowSshFromBastionSubnet --priority 100 \
  --access Allow --direction Inbound --protocol Tcp \
  --source-address-prefixes "${BASTION_SUBNET_PREFIX}" \
  --destination-port-ranges 22


# Deny SSH from the public internet
az network nsg rule create \
  -g "${RG}" --nsg-name "${NSG_NAME}" \
  -n DenyInternetSsh --priority 110 \
  --access Deny --direction Inbound --protocol Tcp \
  --source-address-prefixes Internet \
  --destination-port-ranges 22


# Deny SSH from other VNet sources
az network nsg rule create \
  -g "${RG}" --nsg-name "${NSG_NAME}" \
  -n DenyVnetSsh --priority 120 \
  --access Deny --direction Inbound --protocol Tcp \
  --source-address-prefixes VirtualNetwork \
  --destination-port-ranges 22
```


The rules are evaluated by priority (lowest number first): Bastion traffic is allowed at 100, then all other SSH is blocked at 110 and 120.
 Create the VNet with the VM subnet (NSG attached), then add the Bastion subnet. 
```bash
az network vnet create \
  -g "${RG}" -n "${VNET_NAME}" -l "${LOCATION}" \
  --address-prefixes "${VNET_PREFIX}" \
  --subnet-name "${VM_SUBNET_NAME}" \
  --subnet-prefixes "${VM_SUBNET_PREFIX}"


# Attach the NSG to the VM subnet
az network vnet subnet update \
  -g "${RG}" --vnet-name "${VNET_NAME}" \
  -n "${VM_SUBNET_NAME}" --nsg "${NSG_NAME}"


# AzureBastionSubnet — name is required by Azure
az network vnet subnet create \
  -g "${RG}" --vnet-name "${VNET_NAME}" \
  -n AzureBastionSubnet \
  --address-prefixes "${BASTION_SUBNET_PREFIX}"
```
 The VM has no public IP. SSH access is exclusively through Azure Bastion. 
```bash
az vm create \
  -g "${RG}" -n "${VM_NAME}" -l "${LOCATION}" \
  --image "Canonical:ubuntu-24_04-lts:server:latest" \
  --size "${VM_SIZE}" \
  --os-disk-size-gb "${OS_DISK_SIZE_GB}" \
  --storage-sku StandardSSD_LRS \
  --admin-username "${ADMIN_USERNAME}" \
  --ssh-key-values "${SSH_PUB_KEY}" \
  --vnet-name "${VNET_NAME}" \
  --subnet "${VM_SUBNET_NAME}" \
  --public-ip-address "" \
  --nsg ""
```


`--public-ip-address ""` prevents a public IP from being assigned. `--nsg ""` skips creating a per-NIC NSG (the subnet-level NSG handles security).


**Reproducibility:** The command above uses `latest` for the Ubuntu image. To pin a specific version, list available versions and replace `latest`:


```bash
az vm image list \
  --publisher Canonical --offer ubuntu-24_04-lts \
  --sku server --all -o table
```
 Azure Bastion provides managed SSH access to the VM without exposing a public IP. Standard SKU with tunneling is required for CLI-based `az network bastion ssh`. 
```bash
az network public-ip create \
  -g "${RG}" -n "${BASTION_PIP_NAME}" -l "${LOCATION}" \
  --sku Standard --allocation-method Static


az network bastion create \
  -g "${RG}" -n "${BASTION_NAME}" -l "${LOCATION}" \
  --vnet-name "${VNET_NAME}" \
  --public-ip-address "${BASTION_PIP_NAME}" \
  --sku Standard --enable-tunneling true
```


Bastion provisioning typically takes 5-10 minutes but can take up to 15-30 minutes in some regions.

Install RemoteClaw

```bash VM_ID="$(az vm show -g "${RG}" -n "${VM_NAME}" --query id -o tsv)" 
az network bastion ssh \
  --name "${BASTION_NAME}" \
  --resource-group "${RG}" \
  --target-resource-id "${VM_ID}" \
  --auth-type ssh-key \
  --username "${ADMIN_USERNAME}" \
  --ssh-key ~/.ssh/id_ed25519
```
 ```bash curl -fsSL https://remoteclaw.org/install.sh -o /tmp/install.sh bash /tmp/install.sh rm -f /tmp/install.sh ``` 
The installer installs Node LTS and dependencies if not already present, installs RemoteClaw, and launches the onboarding wizard. See [Install](/install) for details.
 After onboarding completes: 
```bash
remoteclaw gateway status
```


Most enterprise Azure teams already have GitHub Copilot licenses. If that is your case, we recommend choosing the GitHub Copilot provider in the RemoteClaw onboarding wizard. See [GitHub Copilot provider](/providers/github-copilot).

Cost considerations

Azure Bastion Standard SKU runs approximately $140/month and the VM (Standard_B2as_v2) runs approximately $55/month.

To reduce costs:

  • Deallocate the VM when not in use (stops compute billing; disk charges remain). The RemoteClaw Gateway will not be reachable while the VM is deallocated — restart it when you need it live again:

    Terminal window
    az vm deallocate -g "${RG}" -n "${VM_NAME}"
    az vm start -g "${RG}" -n "${VM_NAME}"   # restart later

  • Delete Bastion when not needed and recreate it when you need SSH access. Bastion is the largest cost component and takes only a few minutes to provision.

  • Use the Basic Bastion SKU (~$38/month) if you only need Portal-based SSH and don’t require CLI tunneling (az network bastion ssh).

Cleanup

To delete all resources created by this guide:

Terminal window
az group delete -n "${RG}" --yes --no-wait

This removes the resource group and everything inside it (VM, VNet, NSG, Bastion, public IP).
