Dev mode

One server on SQLite, with the same APIs and security as a cluster.

Dev mode runs management, the edge and an embedded Temporal in one process on SQLite. It has the same APIs and the same security as a cluster, so what works in dev mode works in production.

Terminal
orchestrator-zero server start --dev --data-dir .oz0/dev

The first start in a data directory creates:

  • a cluster named dev with its master key and CAs,
  • the tenant default,
  • an operator context at .oz0/dev/operator/context.json,
  • a reusable join token at .oz0/dev/join-token,
  • the web UI's admin account, with its password in .oz0/dev/admin-password.

Without --data-dir, everything lives in a temporary directory that is removed when the server stops.

The operator's certificate is valid for 90 days. Each start issues a new one when it is missing or has less than 30 days left, so a dev data directory keeps working.

Join a node to it

Terminal
export OZ0_CONTEXT=.oz0/dev/operator/context.json
OZ0_JOIN_TOKEN="$(cat .oz0/dev/join-token)" orchestrator-zero-node join --server https://127.0.0.1:7443
orchestrator-zero-node run --runtime-bundle "$OZ0_RUNTIME_BUNDLE"

In a third terminal, check that the node is there and run something:

Terminal
export OZ0_CONTEXT=.oz0/dev/operator/context.json
orchestrator-zero node list
orchestrator-zero job run --task-queue oz0.default --workflow HelloWorkflow --input '"you"'

Ports in dev mode

Dev mode binds to 127.0.0.1 unless you pass --ip.

PortWhat
7233The edge's Temporal proxy, for nodes
7443The edge's HTTPS API: join, control stream, artifacts, LLM gateway, runtime API
7234The embedded Temporal frontend (only the edge uses it)
8233The Temporal web UI; --temporal-ui-port 0 turns it off
8443Management: the web UI and the admin API, for the CLI

orchestrator-zero dev for plugin authors

If you are building a plugin, orchestrator-zero dev is quicker: it starts a dev server on free ports, joins a node, installs your plugin from its working tree and reinstalls it on every change. See Develop and test.
