Deploy Central Node

The central node orchestrates workflows, hosts the API, and coordinates with worker nodes.

1. Download Service Images

branectl download services central -f
branectl download services auxillary -f

The -f flag creates any missing directories. Images are saved to ./target/release/.

branectl generate infra -f -p ./config/infra.yml \
  hospital-a:hospital-a.example.com \
  hospital-b:192.0.2.2

Worker IDs must match the location IDs configured on the worker nodes.

branectl generate proxy -f -p ./config/proxy.yml

branectl generate node -f central <YOUR_HOSTNAME>

Replace <YOUR_HOSTNAME> with the hostname or IP reachable by worker nodes.

./
  config/
    certs/
    infra.yml
    proxy.yml
  node.yml
  target/
    release/

For each worker, place their CA certificate in a folder named after their location ID:

mkdir -p ./config/certs/hospital-a
cp /path/to/hospital-a-ca.pem ./config/certs/hospital-a/ca.pem

See the configuration reference for details on certificate management.

branectl start central

ScyllaDB may take up to a minute to initialize. Monitor with:

docker ps

Wait until all containers show healthy status.

curl http://localhost:50051/health

Or use the CLI:

brane login http://localhost --username admin
brane package list

branectl stop central

Deploy worker nodes to add compute domains.
