Setup

1. Get a server

Recommended Specs

Type: VPS or dedicated
Distribution: Ubuntu 16.04 (Xenial), 18.04 (Bionic) or 20.04 (Focal)
Memory: 512MB or greater

2. Add a DNS record

Create a DNS A record in your domain pointing to your server's IP address.

Example: subspace.example.com A 172.16.1.1

3. Enable Let's Encrypt

Subspace runs a TLS ("SSL") https server on port 443/tcp. It also runs a standard web server on port 80/tcp to redirect clients to the secure server. Port 80/tcp is required for Let's Encrypt verification.

Requirements

Your server must have a publicly resolvable DNS record.
Your server must be reachable over the internet on ports 80/tcp, 443/tcp and 51820/udp (Default WireGuard port, user changeable).

Usage

Example usage:

$ subspace --http-host subspace.example.com

Command Line Options

flag	default	description
`http-host`		REQUIRED: The host to listen on and set cookies for
`backlink`	`/`	OPTIONAL: The page to set the home button too
`datadir`	`/data`	OPTIONAL: The directory to store data such as the wireguard configuration files
`debug`		OPTIONAL: Place subspace into debug mode for verbose log output
`http-addr`	`:80`	OPTIONAL: HTTP listen address
`http-insecure`		OPTIONAL: enable session cookies for http and remove redirect to https
`letsencrypt`	`true`	OPTIONAL: Whether or not to use a letsencrypt certificate
`theme`	`green`	OPTIONAL: The theme to use, please refer to semantic-ui for accepted colors
`version`		Display version of `subspace` and exit
`help`		Display help and exit

Run as a Docker container

Clear iptable (Optional, Oracle Cloud)

sudo iptables -F && sudo iptables -X && sudo netfilter-persistent save && sudo netfilter-persistent reload

Install WireGuard on the host

The container expects WireGuard to be installed on the host. The official image is subspacecommunity/subspace.

add-apt-repository -y ppa:wireguard/wireguard
apt-get update
apt-get install -y wireguard resolvconf

# Disable systemd-resolved listener if it blocks port 53.
echo "DNSStubListener=no" >> /etc/systemd/resolved.conf
systemctl restart systemd-resolved

# Load modules.
modprobe wireguard
modprobe iptable_nat
modprobe ip6table_nat

# Enable modules when rebooting.
echo "wireguard" > /etc/modules-load.d/wireguard.conf
echo "iptable_nat" > /etc/modules-load.d/iptable_nat.conf
echo "ip6table_nat" > /etc/modules-load.d/ip6table_nat.conf

# Check if systemd-modules-load service is active.
systemctl status systemd-modules-load.service

# Enable IP forwarding.
sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv6.conf.all.forwarding=1

# Enable wg0 self-forwarding
iptables -I FORWARD -i wg0 -o wg0 -j ACCEPT

# Set DNS server.
echo nameserver 8.8.8.8 >> /etc/resolvconf/resolv.conf.d/head
echo nameserver 1.1.1.1 >> /etc/resolvconf/resolv.conf.d/head

systemctl start resolvconf.service
systemctl enable resolvconf.service

resolvconf -u

Follow the official Docker install instructions: Get Docker CE for Ubuntu

Make sure to change the --env SUBSPACE_HTTP_HOST to your publicly accessible domain name.

# Your data directory should be bind-mounted as `/data` inside the container using the `--volume` flag.
$ mkdir /data

docker create \
    --name subspace \
    --restart always \
    --network host \
    --cap-add NET_ADMIN \
    --volume /data:/data \

    --env SUBSPACE_IPV6_POOL="fd00::10:97:0/64" \
	# Optional variables to change IPv4/v6 Gateway
  # (NOTICE: If you change SUBSPACE_IPV{4/6}_POOL, you don't need to set. just commnet out.)
    --env SUBSPACE_IPV4_GW="10.99.97.1" \
    --env SUBSPACE_IPV6_GW="fd00::10:97:1" \
	# Optional variable to enable or disable IPv6 NAT
    --env SUBSPACE_IPV6_NAT_ENABLED=1 \
  # Optionally manage your own caching dns server
    --env SUBSPACE_DNSMASQ_DISABLED=1 \
    ghcr.io/kbc8894/subspace:latest

$ sudo docker start subspace

$ sudo docker logs subspace

Updating the container image

Pull the latest image, remove the container, and re-create the container as explained above.

# Pull the latest image
$ sudo docker pull subspacecommunity/subspace

# Stop the container
$ sudo docker stop subspace

# Remove the container (data is stored on the mounted volume)
$ sudo docker rm subspace

# Re-create and start the container
$ sudo docker create ... (see above)
