Packer Builder for VMware vSphere

This a plugin for HashiCorp Packer. It uses native vSphere API, and creates virtual machines remotely.

• VMware Player is not required
• Builds are incremental, VMs are not created from scratch but cloned from base templates - similar to amazon-ebs builder
• Official vCenter API is used, no ESXi host modification is required

Usage

• Download the plugin from Releases page
• Install the plugin, or simply put it into the same directory with configuration files

• username - [mandatory] vSphere username.
• password - [mandatory] vSphere password.
• insecure_connection - do not validate server's TLS certificate. false by default.
• datacenter - required if there are several datacenters.

Destination:

• template - [mandatory] name of source VM.
• vm_name - [mandatory] name of target VM.
• folder - VM folder where target VM is created.
• host - [mandatory] vSphere host where target VM is created.
• resource_pool - by default a root of vSphere host.
• datastore - required if vSphere host has multiple datastores attached.
• linked_clone - create VM as a linked clone from latest snapshot. false by default.

Hardware customization:

• CPUs - number of CPU sockets. Inherited from source VM by default.
• CPU_reservation - Amount of reserved CPU resources in MHz. Inherited from source VM by default.
• RAM - Amount of RAM in megabytes. Inherited from source VM by default.

Provisioning:

• ssh_username - [mandatory] username in guest OS.

Post-processing:

• shutdown_command - VMware guest tools are used by default.
• shutdown_timeout - Duration how long to wait for a graceful shutdown. 5 minutes by default.
