Starting Your Nodes

Prior to starting up your nodes make sure you have the following items completed:

  1. Bootstrap process completed with the bootstrap directory handy (default: /var/flow/bootstrap)
  2. Flow data directory created (default: /var/flow/data)
  3. node config ready
  4. Firewall exposes TCP/3569, and if you are running access node also the GRPC port (default: TCP/9000)

For more details head back to Setting up your node

When you have all the above completed, you can start your Flow node via systemd or docker.

systemd

Ensure that you downloaded the systemd unit file. If you haven't, follow the Set your node to start guide to get your unit file and enabled.

Once you have your Flow service enabled you can now start your service: systemctl start flow

Docker

If you don't have have systemd on your system, or prefer not to use systemd, you can run the following docker commands for your respective Flow role to start your node!

Access

docker run --rm \
    -v /path/to/bootstrap:/bootstrap:ro \
    -v /path/to/data:/data:rw \
    --name flow-go \
    --network host \
    gcr.io/flow-container-registry/access:v0.0.6-alpha \
    --nodeid=${FLOW_GO_NODE_ID} \
    --bootstrapdir=/bootstrap \
    --datadir=/data/protocol \
    --rpc-addr=0.0.0.0:9000 \
    --ingress-addr=${FLOW_NETWORK_COLLECTION_NODE} \
    --script-addr=${FLOW_NETWORK_EXECUTION_NODE} \

    --loglevel=error

Collection
