helm repo add weaviate https://weaviate.github.io/weaviate-helm
helm install my-weaviate weaviate/weaviate

Documentation can be found here.

Migration from older versions to v1.25.x and above

Weaviate v1.25 has brought a significant change in how we bootstrap the Weaviate cluster. We have changed the podManagementPolicy from OrderedReady to Parallel. This change is required for the Raft-based consensus model that Weaviate now utilizes under the hood. For the Raft cluster to be properly bootstrapped, all pods in the cluster must start simultaneously.

Please note that once the Raft cluster is established, rolling updates are possible. This change will only take effect during migration from versions prior to v1.25 (or when bootstrapping a new v1.25 cluster).

If you are upgrading from a version older than v1.25 to v1.25 and above, you must first delete Weaviate's Statefulset. This is a one-time operation and will not remove your data, it is necessary to make the update of Statefulset settings possible.

Detailed information can be found in the documentation.
