# Distributed Build with Consistent Hashing
Demo for efficiently using BuildKit daemon-local cache with multi-node cluster
## Deploy
```console
$ kubectl apply -f ../statefulset.rootless.yaml
$ kubectl scale --replicas=10 statefulset/buildkitd
```
## Consistent hashing
Define the key string for consistent hashing.
For example, the key can be defined as `<REPO NAME>:<CONTEXT PATH>`, e.g.
`github.com/example/project:some/directory`.
Then determine the pod that corresponds to the key:
```console
$ go build -o consistenthash .
$ pod=$(./show-running-pods.sh | consistenthash $key)
```
You can connect to the pod using `export BUILDKIT_HOST=kube-pod://$pod`.
