You can easily upgrade Milvus 2.0 with Helm Chart. This guide uses the example of upgrading from Milvus v2.0.0-rc4 to v2.0.0-rc5-hotfix1.
Note:
Helm Chart does not support upgrading from Milvus 2.0 standalone to Milvus 2.0 cluster or vice versa. Versions prior to v2.0.0-rc7 does not support upgrading to v2.0.0-rc7.
To upgrade, old pods will be deleted first. Therefore, the service may be offline for a short time.
1. Check current Milvus version:
$ helm list
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
my-release default 1 2021-09-06 14:46:33.920893 +0800 CST deployed milvus-2.1.5 2.0.0-rc.4
In this example, you can see the APP Version is 2.0.0-rc4.
2. Check running pods:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
my-release-etcd-0 1/1 Running 0 110s
my-release-milvus-standalone-66f985d5cd-q5qhj 1/1 Running 0 110s
my-release-minio-5564fbbddc-dw77v 1/1 Running 0 110s
3. Check image tag of milvus-standalone pod:
$ kubectl get pods my-release-milvus-standalone-66f985d5cd-q5qhj -o=jsonpath='{$.spec.containers[0].image}'
milvusdb/milvus:v2.0.0-rc4-20210811-bdb8396
You can see the version of current Milvus Standalone is 2.0.0-rc4
4. Check new Milvus versions:
$ helm search repo milvus --versions
