Gravity Node Middleware

Clone

Firstly, clone repo recursively

git clone --recurse-submodules https://github.com/Gravity-Hub-Org/gravity-node-middleware.git

Dependencies

1. jq (apt-get install jq)
2. Docker
3. bash

Deployment

You can automatically start deploying the environment by calling:

bash pure-start.sh --simple

Or manually:

1. Run Ethereum node in dev mode

Run script and wait for couple of minutes for node to sync.

bash run-geth.sh

2. Build Gravity node image

You should get ethereum node address and its network

Getting address:

Run script and you will get first address of eth.account array inside the geth node.

$ bash geth-helper.sh --node-address
0xba2ab90d58bf5b3fc8f9224c2d07e220dfa41ff0

You can also provide additional overriding params such as:

# --image <image_id> - Docker image ID
# --cont-net <int> - Node network IP
# --cont-port <int> - Node port

Start docker image build:

Regarding image building, consider overriding:

1. Image tag -t <image_name:tag>
2. ETH_ADDRESS must equal to the address of your node. (we extracted it above)
3. ETH_NETWORK must equal to node IP address in docker network.

docker build -f ghnode.dockerfile \
--build-arg ETH_ADDRESS=0x836b7d8d0648c41d212ed19a242a8c91979689f6 \
--build-arg ETH_NETWORK=172.17.0.2 -t gh-node:2 .
