5. Use it from your app

The daemon you started in step 2 is the cluster member. The application is a client of the daemon on the same host.

text

app A ─┐
app B ─┼─► daemon on this host ─► other daemons
cli   ─┘

Two processes on one machine share one daemon. The app does not vote. It does not speak Raft.

Keep clusdr start running. Then pick a language:

Language	Install	Full docs
Go	`go get github.com/odurgut/clusdr/sdk`	Go SDK
Python	`pip install clusdr`	Python SDK

c, err := clusdr.Local()
members, err := c.Members(ctx)
lk, err := c.Lock(ctx, "scheduler", 15*time.Second)

python

from clusdr import local

c = local()
members = c.members()
lk = c.lock("scheduler", ttl=15)

Local / local() dial CLUSDR_GRPC_ADDR or 127.0.0.1:7947. TLS is on; certs come from CLUSDR_DATA_DIR or ~/.clusdr.

What the app must not do: join the cluster, dial a remote Runtime API as the normal path, or treat publish as durable storage.

Model, env, holder, both languages: SDKs.
