Issue/Introduction

Symptoms:

The following error will encounter when you face this issue:

• You see output similar to the following when you run the "tanzu cluster upgrade"  command:

Error: failed to deploy additional components after kubernetes upgrade: unable to get cluster configuration: unable to get template: - assert.fail: fail: TKG_HTTP_PROXY and TKG_HTTPS_PROXY should both be set or left as empty in toplevel 03_customizations/http_proxy.yaml:9 | #@ assert.fail(“TKG_HTTP_PROXY and TKG_HTTPS_PROXY should both be set or left as empty”) Usage: tanzu cluster upgrade CLUSTER_NAME [flags] TKG_HTTP_PROXY and TKG_HTTPS_PROXY are set in the cluster-config file for that cluster

 

Environment

VMware Tanzu Kubernetes Grid 1.x

Cause

User has set the TKG_HTTP_PROXY and TKG_HTTPS_PROXY before creating workload cluster. This is a bug in v1.3.1 that this proxy configuration provided during cluster creation is not getting used during upgrade. 

Resolution

Fixed in upcoming TKG releases. 

Workaround:

You can apply the following workaround :-

• Specify the  TKG_HTTP_PROXY and TKG_HTTPS_PROXY config variables as part of ~/.tanzu/tkg/config.yaml file  or  as Environment variables just before upgrade and rerun the "tanzu cluster upgrade <workload-cluster-name> -v 9" command.
