Introduction

\n

These terraform definitions are going to create the CaaSP v4 cluster on top of VMWare vSphere cluster.

\n

This code was developed and tested on VMware vSphere cluster based on VMware ESXi 7

\n

Deployment

\n

Prepare a VM template machine in vSphere by following vmware-deployment guide.

\n

It doesn't matter if you deploy the VM template for SLES15-SP1 manually by using ISO or you use pregenerated vmdk SLES15-SP1 JeOS image but in both cases you'll need cloud-init-vmware-guestinfo package (from SUSE CaaS Platform module), cloud-init package (from Public Cloud Module) and its dependent packages installed. The respective services must be enabled:

\n
systemctl enable cloud-init cloud-init-local cloud-config cloud-final
\n

Next you need to define following environment variables in your current shell with proper value:

\n
# HINT: Please enter just a hostname without specifing a protocol in VSPHERE_SERVER variable (using https by default).\nexport VSPHERE_SERVER=\"vsphere.cluster.endpoint.fqdn\"\nexport VSPHERE_USER=\"vsphere-admin-username\"\nexport VSPHERE_PASSWORD=\"password\"\nexport VSPHERE_ALLOW_UNVERIFIED_SSL=\"true\"
\n

Once you perform a Customization you can use terraform to deploy the cluster:

\n
terraform init\nterraform validate\nterraform plan\nterraform apply
\n

Machine access

\n

It is important to have your public ssh key within the authorized_keys, this is done by cloud-init through a terraform variable called authorized_keys.

\n

All the instances have a caaspadm user, password is not set. User can login as caaspadm user over SSH by using his private ssh key. The caaspadm user can perform sudo without specifying a password.

\n

Variables

\n

vsphere_datastore - Provide the datastore to use in vSphere
\nvsphere_datacenter - Provide the datacenter to use in vSphere
\nvsphere_network - Provide the network to use in vSphere - this network must be able to access the ntp servers and the nodes must be able to reach each other
\nvsphere_resource_pool - Provide the resource pool the machines will be running in
\ntemplate_name - The template name the machines will be copied from
\nfirmware - Replace the default \"bios\" value with \"efi\" in case your template was created by using EFI firmware
\nauthorized_keys - A list of ssh public keys that will be installed on all nodes
\nrepositories - Additional repositories that will be added on all nodes
\npackages - Additional packages that will be installed on all nodes

\n

`adjust server.txt with the list of servers you want to create (see server.txt.example)

\n

Please use one of the following options:

\n

caasp_registry_code - Provide SUSE CaaSP Product Registration Code in registration.auto.tfvars file to register product against official SCC server
\nrmt_server_name - Provide SUSE Repository Mirroring Tool Server Name in registration.auto.tfvars file to use repositories stored on RMT server\nsuma_server_name - Provide SUSE Manager Server Name in registration.auto.tfvars file to use repositories stored on SUSE Manager server

\n

Open ToDo:

\n

terraform destroy -> need to delete servers from rmt/scc/suse manager\nadd suma registration only in case a suma server is specified (not \"\")\nregister only in case an activation key is specified for a system\nfind out how to re-register a system with the same name but different machine-id to suse manager
