Daemon Deployment on Bare Metal and VMs

This guide covers installing the Riptides daemon and kernel module on bare-metal Linux servers and virtual machines. This approach works for any Linux-based environment outside of Kubernetes, including EC2 instances, GCP VMs, Azure VMs, on-premises hardware, and local development VMs (e.g., Lima).

Prerequisites

• Linux kernel 5.15+ (x86_64 or ARM64)
• Root access
• Network connectivity to the Riptides control plane (ports 8443, 9443, 8001)

Step 1: Install the Kernel Module

The Riptides kernel module provides transparent in-kernel TLS/mTLS termination for TCP sockets.

The recommended way to install it is via the driver-loader package, which automatically detects your kernel version and architecture and downloads and installs the correct driver package. Download the appropriate package from the driver-loader releases page and install it:

Debian / Ubuntu:

sudo dpkg -i riptides-driver-loader_<version>_<arch>.deb
# or
sudo apt install ./riptides-driver-loader_<version>_<arch>.deb

CentOS / Fedora / Amazon Linux:

sudo rpm -i riptides-driver-loader-<version>.<arch>.rpm
# or
sudo dnf install ./riptides-driver-loader-<version>.<arch>.rpm

Alternatively, download the driver package directly from the driver releases page. Select the driver version and the package matching your kernel version and architecture, then install it manually:

# Debian / Ubuntu
sudo dpkg -i riptides-driver-<distro>-<kernel-version>_<driver-version>_<arch>.deb
# e.g. riptides-driver-ubuntu-6.14.0-37-generic_v0.5.15_arm64.deb

# CentOS / Fedora / Amazon Linux
sudo rpm -i riptides-driver-<distro>-<kernel-version>_<driver-version>.<arch>.rpm

Verify the Module

Confirm the kernel module loaded successfully:

# Check kernel messages
sudo dmesg -T | grep riptides

# Verify the module is loaded
lsmod | grep riptides

# Check driver health
cat /proc/riptides/health

The health endpoint will report “waiting for daemon” until the daemon connects and pushes configuration. This is expected.

Step 2: Install the Daemon Binary

Install the daemon from the package repository:

Debian / Ubuntu:

sudo apt install riptides-daemon

RHEL / Fedora / Amazon Linux:

sudo dnf install riptides-daemon

Alternatively, build from source (requires a GitHub account with access to the daemon repository):

git clone https://github.com/riptideslabs/daemon.git
cd daemon
GOOS=linux make build

# The binary is at ./build/riptides
sudo cp ./build/riptides /usr/local/bin/riptides

Step 3: Configure the Daemon

Create the configuration directories:

sudo mkdir -p /etc/riptides/identities
sudo mkdir -p /etc/riptides/services
sudo mkdir -p /etc/riptides/credentials

Create a configuration file at /etc/riptides/config.yaml:

daemon:
  trustDomain: example.com
  defaultCertTTL: 2h
  dataDir: /var/lib/riptides

  metadataCollectors:
    procfs:
      enabled: true
      extractEnvs: false
    linuxos:
      enabled: true
    sysfsdmi:
      enabled: true
    ec2:
      enabled: false    # Set to true on AWS EC2
    gcp:
      enabled: false    # Set to true on GCP
    azure:
      enabled: false    # Set to true on Azure
    kubernetes:
      enabled: false    # Disable on bare metal
    docker:
      enabled: false

  controlPlane:
    enabled: true
    url: https://cp.example.com
    grpcServerAddress: grpc.example.com:443
    tokenBrokerBaseURL: https://cp.example.com/token-broker
    authPlugin:
      type: joinToken
      config:
        token: "your-join-token-here"

  tunnelServer:
    address: tunnel.example.com:443

Enable the cloud metadata collectors relevant to your environment:

• AWS EC2: Set ec2.enabled: true and use authPlugin.type: AWSIID for automatic attestation
• GCP: Set gcp.enabled: true and use authPlugin.type: GCPIIT
• Azure: Set azure.enabled: true
• On-premises / local VMs: Use authPlugin.type: joinToken with a pre-shared token

Step 4: Run the Daemon

Run the daemon manually:

sudo riptides daemon \
  --identities-path /etc/riptides/identities \
  --services-path /etc/riptides/services \
  --credentials-path /etc/riptides/credentials

Run as a systemd Service

Create a systemd unit file at /etc/systemd/system/riptides-daemon.service:

[Unit]
Description=Riptides Daemon
After=network-online.target
Wants=network-online.target
ConditionPathExists=/dev/riptides

[Service]
Type=simple
ExecStart=/usr/local/bin/riptides daemon \
  --identities-path /etc/riptides/identities \
  --services-path /etc/riptides/services \
  --credentials-path /etc/riptides/credentials
Restart=always
RestartSec=5
LimitNOFILE=65536

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable riptides-daemon
sudo systemctl start riptides-daemon
sudo systemctl status riptides-daemon

Step 5: Verify

Once the daemon is running, the driver health should report OK:

cat /proc/riptides/health

Check daemon logs:

# If running as a systemd service
sudo journalctl -u riptides-daemon -f

# If running manually, logs go to stdout/stderr

Local Development with Lima

You can run Riptides in a local Lima VM for development and testing. Install the kernel module and daemon inside the VM using the same steps above, and connect it to the hosted control plane using a JoinToken.

This is useful for testing workload identity assignment and credential injection locally before deploying to production infrastructure.

Diagnostics

The Riptides kernel module exposes several diagnostic endpoints for troubleshooting.

Direct Endpoints

Path	Description
/proc/riptides/health	Driver health status
/proc/riptides/certificates	Currently loaded certificates
/proc/riptides/connections	Active connection state
/proc/riptides/trust_anchors	Trust anchor chain
/sys/module/riptides/credentials/	Credential files loaded by the daemon

Example — dump certificates directly:

cat /proc/riptides/certificates | python3 -m json.tool

Example — enable kernel dynamic debug for the module:

echo -n '-p; module riptides +pftl' | sudo tee /proc/dynamic_debug/control > /dev/null

Uninstalling

Remove the Daemon

sudo systemctl stop riptides-daemon
sudo systemctl disable riptides-daemon
sudo rm /etc/systemd/system/riptides-daemon.service
sudo systemctl daemon-reload

If installed via package:

sudo apt remove riptides-daemon    # Debian/Ubuntu
sudo dnf remove riptides-daemon    # RHEL/Fedora

Remove the Kernel Module

# Unload the module
sudo modprobe -r riptides

# Remove the package
sudo apt remove riptides-driver    # Debian/Ubuntu
sudo dnf remove riptides-driver    # RHEL/Fedora

Example: AWS EC2 Deployment

A complete configuration for an EC2 instance that attests using the instance identity document:

daemon:
  trustDomain: example.com
  defaultCertTTL: 2h
  dataDir: /var/lib/riptides

  metadataCollectors:
    procfs:
      enabled: true
      extractEnvs: false
    linuxos:
      enabled: true
    sysfsdmi:
      enabled: true
    ec2:
      enabled: true
    gcp:
      enabled: false
    azure:
      enabled: false
    kubernetes:
      enabled: false
    docker:
      enabled: false

  controlPlane:
    enabled: true
    url: https://cp.example.com
    grpcServerAddress: grpc.example.com:443
    tokenBrokerBaseURL: https://cp.example.com/token-broker
    authPlugin:
      type: AWSIID

  tunnelServer:
    address: tunnel.example.com:443

No shared secrets are needed — the daemon uses the EC2 instance identity document signed by AWS for attestation with the control plane.
