+# packer-builder-vsphere
+
+## Installation instructions
+
+0. It is supposed that you already have Go(and [Packer](https://github.com/hashicorp/packer)), [Docker-compose](https://docs.docker.com/compose/install/) and [Glide](https://github.com/Masterminds/glide) set.
+
+1. Download the sourcces from [github.com/LizaTretyakova/packer-builder-vsphere](github.com/LizaTretyakova/packer-builder-vsphere)
+
+2. `cd` to `$GOPATH/go/src/github.com/LizaTretyakova/packer-builder-vsphere` (or wherever it was downloaded)
+
+3. Build the binaries
+```
+$ sudo docker-compose up
+```
+
+4. The template for this builder is like following:
+```json
+{
+    "variables": {
+            "url": "{{env `YOUR_VSPHERE_URL`}}",
+            "username": "{{env `YOUR_VSPHERE_USERNAME`}}",
+            "password": "{{env `YOUR_VSPHERE_PASSWORD`}}",
+            "ssh_username": "{{env `TEMPLATE_VM_SSH_USERNAME`}}",
+            "ssh_password": "{{env `TEMPLATE_VM_SSH_PASSWORD`}}",
+            "dc_name": "{{env `TEMPLATE_VM_DATACENTER`}}",
+            "template": "{{env `TEMPLATE_VM_NAME`}}"
+    },
+    "builders": [
+        {
+            "type": "vsphere",
+            "url": "{{user `url`}}",
+            "username": "{{user `username`}}",
+            "password": "{{user `password`}}",
+            "ssh_username": "{{user `ssh_username`}}",
+            "ssh_password": "{{user `ssh_password`}}",
+            "dc_name": "{{user `dc_name`}}",
+            "template": "{{user `template`}}",
+            "vm_name": "new_vm_name",
+            "RAM": "1024",
+            "cpus": "2",
+            "shutdown_command": "echo '{{user `ssh_password`}}' | sudo -S shutdown -P now"
+        } 
+    ]
+}
+```
+where `vm_name`, `RAM`, `cpus` and `shutdown_command` are parameters of the new VM. 
+Parameters `ssh_*`, `dc_name` (datacenter name) and `template` (the name of the base VM) are for the base VM, 
+on which you are creating the new one (note, that VMWare Tools should be already installed on this template machine).
+`url`, `username` and `password` are your vSphere parameters.
+You need to set the appropriate values in the `variables` section before proceeding.
+
+5. Now you can go to the `bin/` directory
+```
+$ cd ./bin
+```
+and try the builder
+```
+$ packer build template.json
+```
