Build

You could use Dockerfile to build Peer node by himself.

1. Clone repository with dependecies

git clone --recursive https://github.com/metahashorg/peer_node.git

2. Run docker build and wait for a while

sudo docker build -t user/peer_node:latest

You can use this image with our start script. Please change APP="metahash/peer_node:latest" to APP="user/peer_node:latest" and comment or remove sudo docker pull $APP line

Start, stop, restart

1. Check peer status

$ sudo docker ps
CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS              PORTS               NAMES
ad96039f1bed        metahash/peer_node:latest      "/app/peer_node p…"      13 seconds ago      Up 12 seconds                           peer_node

2. Run start script again to update peer_node to latest version and restart
3. Run docker stop peer_node to temporary stop peer
4. Run

sudo docker update --restart=no peer_node
sudo docker stop peer_node

to permanently stop peer
