Dockerized RoboSats stack. Docker compose with services for nginx, redis, gunicorn, daphne, bitcoind, lnd/cln, back-up, celery, celery-beats and other tools.

Setup

Let's assume you are using a newly installed OS. For this setup guide we are using ubuntu server 22.04 (LTS)

Install TOR

Excerpt from https://linuxconfig.org/install-tor-proxy-on-ubuntu-20-04-linux

sudo apt install tor -y

You can optionally torify the shell persistently

echo ". torsocks on" >> ~/.bashrc

In case you need to turn off the torification in the future

source torsocks off

Install Docker on Ubuntu

Excerpt from https://docs.docker.com/engine/install/ubuntu/

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the repository to Apt sources:
echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

# Install
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Test
sudo docker run hello-world

You can optionally add a symlink to docker image and containers path to another path location

sudo systemctl stop docker, 

sudo rm /var/liv/docker

ln -s /desired/path/docker /var/lib/docker

And restart Docker service

service docker restart

Clone and configure RoboSats deploy

Clone this repo

git clone git@github.com:RoboSats/robosats-deploy.git
cd robosats-deploy/compose

Create or restore the environmental configuration files in new folder /compose/env/ directory. You can use the env-sample files as a guide for your configuration, be exhaustive and make sure every setting is right. The file compose.env contains all the high level configuration for your orchestration.

cp -r env-sample env

Then edit and make sure the paths and configurations are right.

nano env/{namespace}/compose...env
nano env/{namespace}/crobosats...env
nano env/{namespace}/lnd.conf
...

If you were already running robosats-deploy/compose in another machine and need to recover, simply bring your existing environmental files from your backup.

In /compose/env/compose...env there is a variable named SUFFIX . This one is used to suffix all of your containers and configuration files. For example if you use -tn (for testnet), your bitcoind service will be called btc-tn, this is an effective way of creating namespaces. The example configuration in /compose/env-sample/ uses the prefix -lndtn, for a LND testnet coordinator. This way, it is easy to run several coordinator orchestration in the same machine. For example, you can use the -lndmn prefix for a LND mainnet coordinator configuration or -clntn for a CLN Testnet configuration. You can also create alias shortcuts for each of your orchestration.

Use aliases

Docker commands are lengthy. You can use aliases to make your task of operating a docker compose based robosats coordinator easier. Take a look at /compose/aliases.sh for some useful aliases and shortcuts.

Example commands for a lnd testnet orchestration (-lndtn containers)

If you install the aliases you can run the following shortcut commands:

tn build # instead of docker compose -p lndtest --env-file  /home/$(whoami)/robosats-deploy/compose/env/stack-lndtn.env -f /home/$(whoami)/robosats-deploy/compose/docker-compose.yml -f /home/$(whoami)/robosats-deploy/compose/docker-compose.override-lnd.yml build
tn up -d
# Now the full coordinator orchestration is running

If this is a new coordinator installation, you need to create an admin RoboSats account. Make sure your superuser name matches the ESCROW_USERNAME in the robosats...env file, by default "admin" .

tn-manage createsuperuser # `tn-manage` is the alias for `docker exec -it rs-lndtn python3 manage.py`
# Enter a username (admin) and a password. Everything else can be skipped by pressing enter.
# You can now visit the coordinator panel at "ip:port/coordinator" in your browser

docker compose -p lndtest --env-file env/stack-lndtn.env build
docker compose -p lndtest --env-file env/stack-lndtn.env up -d
docker exec -it rs-lndtn cp -R frontend/static/frontend /usr/src/static
docker exec -it rs-lndtn python3 manage.py createsuperuser
docker compose -p lndtest --env-file env/stack-lndtn.env restart

You could also just check all services logs

tn logs -f

Unlock or 'create' the lnd node

tn-lncli unlock

Create p2wkh addresses

tn-lncli newaddress p2wkh (note without alias this command would be docker exec -it lnd-lndtn lncli --network=testnet newaddress p2wkh)

Wallet balance

tn-lncli walletbalance

Connect

tn-lncli connect node_id@ip:9735

Open channel

tn-lncli openchannel node_id --local_amt LOCAL_AMT --push_amt PUSH_AMT

If needed; this is how to clean restart the docker instance

Stop the container(s) using the following command:

docker compose -p lndtest --env-file /home/$(whoami)/robosats-deploy/compose/env/stack-lndtn.env -f /home/$(whoami)/robosats-deploy/compose/docker-compose.yml -f /home/$(whoami)/robosats-deploy/compose/docker-compose.override-lnd.yml down Delete all containers using the following command: docker rm -f $(docker ps -a -q) Delete all volumes using the following command: docker volume rm $(docker volume ls -q) Restart the containers using the following command: docker compose -p robotest --env-file env/stack-lndtn.env up

Delete images docker rmi $(docker images -f 'dangling=true' -q)

Add Onion services

At the moment the RoboSats image does not use TorControl of the Tor container to automatically generate the Onion hidden service. It simply exposes the port (18000 in the /compose/env-sample testnet orchestration) and exposes a hidden service defined /env/{namespace}/torrc.

You can edit torcc to add or remove services (e.g., expose Thunderhub as a hidden service)

 sudo nano /env/{namespace}/torrc

# Robosats Testnet Onion Service
HiddenServiceDir /var/lib/tor/robotest/
HiddenServiceVersion 3
HiddenServicePort 80 127.0.0.1:18000
#... mainnet over robotest
HiddenServicePort 8001 127.0.0.1:8000

You can print the hidden service hostname.

sudo cat /env/{namespace}/tor/robotest/hostname

Note that if you try to now access your RoboSats instance by pasting this Onion address in your browser you will see a 400 Error. This is due to the hostname not being allowed by the backend. You have to edit your /env/{namespace}/robosats.env and add your .....onion as HOST_NAME or HOST_NAME2.

And if you want so, you can replace the ed25519 keys to set your own custom hostname. You can mine a vanity onion with mkp224o

Additionally, you can also edit your machine's /etc/tor/torrc to create Onion endpoints to SSH remotely into your machine or to services to monitor your server (e.g Cockpit).

# SSH Hidden Service
HiddenServiceDir /var/lib/tor/sshd/
HiddenServiceVersion 3
HiddenServicePort 22 127.0.0.1:22


# Management Services
HiddenServiceDir /var/lib/tor/management/
HiddenServiceVersion 3
# Cockpit
HiddenServicePort 1000 127.0.0.1:9090

Restart

sudo /etc/init.d/tor restart

Install Cockpit

Just a useful tool to monitor your machine that might come handy. Specially useful if you use ZFS as file system (recommended).

sudo apt-get install cockpit -y
sudo systemctl enable --now cockpit.socket
sudo apt-get install podman cockpit-podman -y
sudo systemctl enable --now podman
git clone https://github.com/45Drives/cockpit-zfs-manager.git
sudo cp -r cockpit-zfs-manager/zfs /usr/share/cockpit
sudo apt-get install samba -y

Access cockpit on port 9090
