First-time setup#

1. Configure spindle#

cp .env.example .env
# edit .env — set SPINDLE_SERVER_HOSTNAME and SPINDLE_SERVER_OWNER

2. Start OpenBao only#

docker compose up -d openbao

Wait for it to be healthy (~5 s), then:

3. Initialise the vault#

chmod +x scripts/init-openbao.sh
./scripts/init-openbao.sh

Save the unseal key and root token printed to stdout.

4. Start the rest of the stack#

docker compose up -d

Spindle comes up only after the proxy is healthy, which is after the vault is unsealed and AppRole credentials are in the shared volume.

After a restart#

OpenBao is sealed on every restart — that's intentional for production. Unseal it before the proxy (and therefore spindle) can authenticate:

docker compose exec openbao bao operator unseal http://localhost:8200 <unseal_key>

Or automate this with a secrets manager / HSM if you don't want manual steps.

Verify#

# proxy health
curl http://localhost:8201/v1/sys/health

# spindle port
curl http://localhost:6555/

Notes#

Spindle mounts /var/run/docker.sock so it can spawn pipeline containers on the host Docker daemon — make sure the spindle user has permission.
TLS is disabled on both listeners; put a reverse proxy (nginx/caddy) in front for production traffic.
The openbao-approle volume holds the role-id/secret-id written by the init script and mounted read-only by the proxy container.
