We expect all Pods to run ClickHouse version `19.1.10` as specified in [initial manifest][initial-manifest].
We expect all Pods to run ClickHouse version `23.3.0` as specified in [initial manifest][initial-manifest].

Let's explore all Pods in order to check available ClickHouse version.
Navigate directly inside each Pod
```bash
kubectl -n dev exec -it chi-06791a-28a0-0-0-0 -- clickhouse-client
```
```text
ClickHouse client version 19.1.10.
ClickHouse client version 23.3.0.
Connecting to localhost:9000.
Connected to ClickHouse server version 19.1.10 revision 54413.
Connected to ClickHouse server version 23.3.0 revision 54413.
```
Repeat for all Pods
```bash
kubectl -n dev exec -it chi-06791a-28a0-0-1-0 -- clickhouse-client
```
```text
ClickHouse client version 19.1.10.

Connecting to localhost:9000.
Connected to ClickHouse server version 19.1.10 revision 54413.
Connected to ClickHouse server version 23.3.0 revision 54413.
```
And the last Pod
```bash
kubectl -n dev exec -it chi-06791a-28a0-0-2-0 -- clickhouse-client
```

Connected to ClickHouse server version 23.3.0 revision 54413.
```
All is fine, all Pods are running `19.1.10`

We'll make Version Update in two steps:
1. Update one ClickHouse instance (one Pod)

We can do by explicitly specifying `templates` with different ClickHouse version:
```yaml
templates:
podTemplate: clickhouse:19.3.7
podTemplate: clickhouse:23.8.0
```
Manifest file with one ClickHouse instance update is [08-clickhouse-version-update-02-apply-update-one.yaml][08-clickhouse-version-update-02-apply-update-one.yaml]:
```bash
kubectl -n dev apply -f 08-clickhouse-version-update-02-apply-update-one.yaml
```
And let's check what ClickHouse versions are running over the whole cluster. We expect the last instance to run specific version `19.3.7`. Check the first Pod:

As we can see - it runs different, explicitly specified version `19.3.7`.

All seems to be good. Let's update the whole cluster now.
