vSphere Integrated Containers Plug-In Not Deploying Correctly

After you have installed the plug-in for vSphere Integrated Containers, the HTML5 vSphere Client plug-in appears but is empty, or the plug-in does not appear at all in one or both of the HTML5 vSphere Client or the Flex-based vSphere Web Client.

Problem

The UI plug-in installer reported success, but you experience one of the following problems:

The HTML5 plug-in appears in the vSphere Client, but the vSphere Integrated Containers Summary, Virtual Container Hosts, and Containers tabs are empty.
The plug-in does not appear in the client at all.

Logging out of the client and logging back in again does not resolve the problem.

Causes

If the vSphere Integrated Containers plug-in appears in the HTML5 client but the tabs are empty, you are not running the correct version of vCenter Server 6.5.0. The vSphere Integrated Containers HTML5 plug-in requires vCenter Server 6.5.0d or later.

If the plug-in does not appear at all:

A previous attempt at installing the vSphere Integrated Containers plug-in failed, and the failed installation state was retained in the client cache.
You installed a new version of the vSphere Integrated Containers plug-in that has the same version number as the previous version, for example a hot patch.
You might be encountering an SSL certificate mismatch issue. This can occur if the root CA on the vCenter Server Virtual Appliance is updated, either by upgrading to a newer build of vSphere or by running the VMCA Certificate Manager.

Solutions

If the vSphere Integrated Containers plug-in appears in the HTML5 client but the tabs are empty, upgrade vCenter Server to version 6.5.0d or later.
If the plug-in does not appear at all, see the section below to restart the vSphere Client services.
If the plug-in still does not appear after restarting the vSphere Client services, see https://kb.vmware.com/kb/52540.

Restart the vSphere Client Services

You restart the Flex-based vSphere Web Client or the HTML5 vSphere Client in different ways.

Restart the HTML5 Client from the Flex-based vSphere Web Client

Log into the Flex-based vSphere Web Client.
Go to Administration > System Configuration > Services.
Right-click VMware vSphere Client and select Restart.

You cannot restart the Flex-based vSphere Web Client from the Flex-based client or from the HTML5 vSphere Client.

Restart the HTML5 Client on vCenter Server on Windows

Log into the Windows system on which vCenter Server is running.
Open a command prompt as Administrator.

Use the service-control command-line utility to stop and then restart the vSphere Client service.

"C:\Program Files\VMware\vCenter Server\bin\service-control" --stop vsphere-ui

"C:\Program Files\VMware\vCenter Server\bin\service-control" --start vsphere-ui

Restart the Flex Client on vCenter Server on Windows

Log into the Windows system on which vCenter Server is running.
Open a command prompt as Administrator.

Use the service-control command-line utility to stop and then restart the vSphere Client service.

"C:\Program Files\VMware\vCenter Server\bin\service-control" --stop vsphere-client

"C:\Program Files\VMware\vCenter Server\bin\service-control" --start vsphere-client

Restart the HTML5 Client on a vCenter Server Appliance

Use SSH to log in to the vCenter Server Appliance as root.
Use the service-control command-line utility to restart the vSphere Client service.
```
service-control --stop vsphere-ui && service-control --start vsphere-ui
```

Restart the Flex Client on a vCenter Server Appliance

Use SSH to log in to the vCenter Server Appliance as root.
Use the service-control command-line utility to stop the vSphere Web Client service.
```
service-control --stop vsphere-client && service-control --start vsphere-client
```
