# SGX-enabled Secret Node in Docker
So you don't want to fiddle with the .deb file, and just want to run your node? We got you, with this quick and easy guide to getting a node started without much tinkering.
This guide will help you set up a node, but you will need to maintain it, or change the default setup. We recommend being familiar with Linux, docker, and docker-compose.
The scripts in the guide will be for Linux (tested on Ubuntu 20.04), but you could get this working on Windows if you swing that way too.
- A public IP address
- Open ports
TCP 26656 & 26657Note: If you're behind a router or firewall then you'll need to port forward on the network device.
- Reading https://docs.tendermint.com/master/tendermint-core/running-in-production.html
- Outbound network connection (you will need to connect to a remote service for this setup)
# Minimum requirements
- 16GB RAM (and 10 GB of swap memory)
- 100GB HDD
- 1 dedicated core of any Intel Skylake processor (Intel® 6th generation) or better
# Recommended requirements
- 32GB RAM
- 256GB SSD
- 2 dedicated cores of any Intel Skylake processor (Intel® 6th generation) or better
- Motherboard with support for SGX in the BIOS
Refer to https://ark.intel.com/content/www/us/en/ark.html#@Processors if unsure if your processor supports SGX.
# 0. Step up SGX on your local machine
See instructions here
# 1. Make sure you have the SGX device installed
If you're using Linux either
/dev/isgx should exist depending on the driver and hardware you're using.
# 2. Install docker & docker-compose
Either install yourself, or use this script for Ubuntu
Run as root
#! /bin/bash # Run as root apt update apt install apt-transport-https ca-certificates curl software-properties-common -y curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add - add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" apt update apt install docker-ce -y # systemctl status docker curl -L https://github.com/docker/compose/releases/download/1.26.0/docker-compose-"$(uname -s)"-"$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose docker-compose --version
# 3. Set up
We use this folder to communicate with the aesm (architectural enclave service manager) service. You can use any other folder you want, just change the paths in the scripts
You may have to run this after a reboot, as well, since the /tmp/ folders are volatile.
#! /bin/bash # Aesm service relies on this folder and having write permissions # shellcheck disable=SC2174 mkdir -p -m 777 /tmp/aesmd chmod -R -f 777 /tmp/aesmd || sudo chmod -R -f 777 /tmp/aesmd || true
# 4. Create the docker-compose file
Edit the path under
devices to match to your device from step 1
version: "3.4" services: aesm: image: enigmampc/aesm devices: - /dev/isgx volumes: - /tmp/aesmd:/var/run/aesmd stdin_open: true tty: true node: image: enigmampc/secret-network-node:v1.2.0-mainnet devices: - /dev/isgx volumes: - /tmp/aesmd:/var/run/aesmd - /tmp/.secretd:/root/.secretd - /tmp/.secretcli:/root/.secretcli - /tmp/.sgx_secrets:/root/.sgx_secrets environment: - SGX_MODE=HW - MONIKER - RPC_URL - CHAINID - PERSISTENT_PEERS - REGISTRATION_SERVICE healthcheck: test: ["CMD", "curl", "-f", "http://127.0.0.1:26657"] interval: 1m30s timeout: 10s retries: 3 start_period: 40s ports: - "26656:26656" - "26657:26657"
NOTE: If you want to persist the node beyond a reboot, change the paths
- /tmp/.secretd:/root/.secretd - /tmp/.sgx_secrets:/root/.sgx_secrets
To something persistent (e.g. in your home directory) like:
- /home/bob/.secretd:/root/.secretd - /home/bob/.sgx_secrets:/root/.sgx_secrets
Note: If you delete or lose either the .secretd or the .sgx_secrets folder your node will have to reset and resync itself.
# 5. Set up environment variables
- MONIKER - your network name
- RPC_URL - address of a node with an open RPC service (you can use
- CHAINID - chain-id of the network (for testnet this is
supernova-1, for mainnet this is
- PERSISTENT_PEERS - List of peers to connect to initially (for this testnet use
- REGISTRATION_SERVICE - Address of registration service (this will help the node start automatically without going through all the manual steps in the other guide) -
You can set an environment variable using the
# 6. Start your node
docker-compose up -d
After creating the machine a healthy status of the node will have 2 containers active:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES bf9ba8dd0802 enigmampc/secret-network-node:v1.2.0 "/bin/bash startup.sh" 13 minutes ago Up 13 minutes (healthy) 0.0.0.0:26656-26657->26656-26657/tcp secret-node_node_1 2405b23aa1bd cashmaney/aesm "/bin/sh -c './aesm_…" 13 minutes ago Up 13 minutes secret-node_aesm_1
# 7. Helpful aliases
We recommend setting the following aliases, which will allow you to transparently use the
secretcli commands from the host (rather than having to exec into the container)
echo 'alias secretcli="docker exec -it secret-node_node_1 secretcli"' >> $HOME/.bashrc echo 'alias secretd="docker exec -it secret-node_node_1 secretd"' >> $HOME/.bashrc
secret-node_node_1 should be the name of the node container (but it may be different, you can check with
# 8. Troubleshooting
You can see the logs of the node by checking the docker logs of the node container:
docker logs secret-node_node_1
If you want to debug/do other stuff with your node you can exec into the actual node using
docker exec -it secret-node_node_1 /bin/bash
