packer-builder-vsphere

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. On Linux and macOS run chmod +x on the plugin binary.

Minimal Example

{
  "builders": [
    {
      "type": "vsphere",

      "vcenter_server": "vcenter.domain.com",
      "username": "root",
      "password": "secret",

      "template": "ubuntu",
      "vm_name":  "vm-1",
      "host":     "esxi-1.domain.com",

      "ssh_username": "root",
      "ssh_password": "secret"
    }
  ],
  "provisioners": [
    {
      "type": "shell",
      "inline": [ "echo hello" ]
    }
  ]
}

Parameters

Connection:

• vcenter_server - [mandatory] vCenter server hostname.
• 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.

Location:

• template - [mandatory] name of source VM. Path is optional.
• vm_name - [mandatory] name of target VM.
• folder - VM folder where target VM is created.
• host - [mandatory] vSphere host or cluster where target VM is created. If hosts are groupped into folders, full path should be specified: folder/host.
• resource_pool - by default a root of vSphere host.
• datastore - required if target is a cluster, or a host with multiple datastores.
• 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.
• CPU_limit - Upper limit of available CPU resources in MHz. Inherited from source VM by default, set to -1 for reset.
• RAM - Amount of RAM in megabytes. Inherited from source VM by default.
• RAM_reservation - Amount of reserved RAM in MB. Inherited from source VM by default.
• RAM_reserve_all - Reserve all available RAM (bool). false by default. Cannot be used together with RAM_reservation.
• disk_size - Change the disk size (in GB). VM should have a single disk. Cannot be used together with linked_clone.

Provisioning:

• ssh_username - [mandatory] username in guest OS.
• ssh_password or ssh_private_key_file - [mandatory] password or SSH-key filename to access a 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.
• create_snapshot - add a snapshot, so VM can be used as a base for linked clones. false by default.
• convert_to_template - convert VM to a template. false by default.
