Add Virtual Container Host (VCH) to vRealize Automation

As part of the Container features, there are also three new roles:
– Container Administrator
– Container Architect
– Container Developer
For the purpose of this guide, I need to assign all thre roles.

After assigning any of these roles, you are going to see the “Containers” Tab at the Top.

For those of you, who happened to play with VMware Admiral before, this interface should look very familiar.

Deploy the Virtual Container Host (VCH)

First, you need to download the vSphere Integrated Containers Engine Bundle and put it somewhere, from where you can access your vCenter.
I’m using a simple Ubuntu Jump-Host.
After extracting it, it leaves you with the VCH ISO file (appliance.iso) and the cli interfaces for Windows, Linux and MacOS.

root@ubu:~# tar zxvf vic_v1.5.3.tar.gz
vic/
vic/vic-machine-server
vic/autocomplete/
vic/autocomplete/zsh/
vic/autocomplete/zsh/vic-machine-windows.exe

vic/bootstrap.iso
vic/vic-machine-windows.exe

root@ubu:~#

The CLI is ready, so let’s compose the command to create the VCH:

vic-machine-linux create
#Call the Linux CLI
--name VCH-3
#Specifies the name of the VM
--container-name-convention vch-{id}
#Defines the naming convention for the containers "vch-docker-id"
--target vcsa.cloudborn.lab/DC1
#Specifies the vCenter and the Datacenter within it
--compute-resource COMP
#Specifies the exact location where to put the VM; in my case, COMP is a Cluster, but you could also define an esxi host
--user Administrator@VSPHERE.LOCAL
#The user beeing used to deploy the VCH
--image-store vsanDatastore/VCH-Images
#Specifies where the container images are stored "datastore/folder", if the folder does not exists, it'll be created
--volume-store vsanDatastore/VCH-DSs:docker-ds
#Specifies where the (persistent) volumes are created, could also be an NFS mount point - "datastore/path:label"
--bridge-network vDS-COMP-vic-bridge
#The internal network, used for container-to-container communication; it's highly recommended to not share this between multiple VCH
--bridge-network-range 172.16.0.0/24
#Network range for internal container-to-container communication
--public-network vDS-COMP-vic-public
#Public network where the VCH host also publishes the port-mappings from the containers
--public-network-ip 10.0.60.3/24
#Network range for public network
--public-network-gateway 10.0.60.1
#Public Network gateway
--dns-server 10.0.1.10
#DNS server
--ops-user vic-vc@cloudborn.lab
#The User beeing used for ops activities later on (creating containers, files, etc,...)
--ops-grant-perms 
#This will grant the required permissions automatically to the --ops-user
--tls-cname VCH-3
#Common name of the vm for SSL certificate
--certificate-key-size 2048
#SSL key size
--no-tlsverify
#This completely disables client authentication via SSL certificate --> everyone who can reach this VMs IP can fire docker cli/api commands against it --> obviously not recommended in production
--thumbprint 6A:1A:98:C4:D3:CB:27:22:C9:46:A6:B1:5B:55:00:63:27:FF:E4:36
#SSL Thumbprint of the vCenter / ESXi, specified as the target

If everything goes well, it should look like this:

Line 67 shows the URL for the admin portal of the VCH. It gives you a brief status report and a lot of logs.
Line 79 shows you the docker endpoint. Let’s check if it is responding:

Looks good to me!
In case, the deployment goes wrong, check the vpxd.log in the CLI directory.

If you happen to have the vSphere Integrated Container Appliance in place and connected to your vCenter, you could also deploy the VCH, using the GUI, as shown in my posts “Deploy Virtual Container Host for vSphere integrated Containers

Adding the VCH to vRealize Automation

The only thing left now, is to add the VCH to our vRA environment.
So login with an account that has at least the role “Container Administrator”.
Navigate to Containers –> Infrastructure –> Container Host Clusters
Click +Cluster

Now enter a name, choose Type “VCH” and enter the docker endpoint as URL.
Since I’ve deployed the host with the “–no-tlsverify” flag, I don’t have to provide any Credentials.

Hit Save, check and accept the Host certificate.
It should only take a few seconds until your host appears.

If you face an error saying “Project context is required”, make sure that your user is part of at least one Business Group. You can select it in the upper left corner.

vRA has now a VCH to provision containers to.
