# Kubernetes V1 Provider Removed

### Issue <a href="#issue" id="issue"></a>

When you upgrade to Armory Spinnaker 2.21 and still use the Kubernetes V1 provider, you will encounter the following error:

```
2020-07-31 22:11:55.146  WARN 1 --- [           main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'configurationRefreshListener' defined in URL [jar:file:/opt/clouddriver/lib/clouddriver-web-6.10.0-20200625140019.jar!/com/netflix/spinnaker/clouddriver/listeners/ConfigurationRefreshListener.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kubernetesV2ProviderSynchronizable': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: The legacy Kubernetes provider (V1) is no longer supported. Please migrate all Kubernetes accounts to the standard provider (V2).
```

This error is followed by the following error message that gets repeated:
