provider/azurerm: Add example of vm custom image w/new storage account (#14468)
* initial commit - 101-vm-from-user-image * changed branch name * not deploying - storage problems * provisions vm but image not properly prepared * storage not correct * provisions properly * changed main.tf to azuredeploy.tf * added tfvars and info for README * tfvars ignored and corrected file ext * added CI config; added sane defaults for variables; updated deployment script, added mac specific deployment for local testing * deploy.sh to be executable * executable deploy files * added CI files; changed vars * prep for PR * removal of old folder * prep for PR * wrong args for travis * more PR prep * updated README * commented out variables in terraform.tfvars * Topic 101 vm from user image (#2) * initial commit - 101-vm-from-user-image * added tfvars and info for README * added CI config; added sane defaults for variables; updated deployment script, added mac specific deployment for local testing * prep for PR * added new template * oops, left off master * prep for PR * correct repository for destination * renamed scripts to be more intuitive; added check for docker * merge vm simple; vm from image * initial commit * deploys locally * updated deploy * consolidated deploy and after_deploy into a single script; simplified ci process; added os_profile_linux_config * added terraform show * changed to allow http & https (like ARM tmplt) * changed host_name & host_name variable desc * added az cli check * on this branch, only build test_dir; master will aggregate all the examples * merge master * added new constructs/naming for deploy scripts, etc. * suppress az login output * suppress az login output * forgot about line breaks * breaking build as an example * fixing broken build example * merge of CI config * fixed grammar in readme * prep for PR * took out armviz button and minor README changes * changed host_name * fixed merge conflicts * changed host_name variable * updating Hashicorp's changes to merged simple linux branch * updating files to merge w/master and prep for Hashicorp pr * Revert "updating files to merge w/master and prep for Hashicorp pr" This reverts commit b850cd5d2a858eff073fc5a1097a6813d0f8b362. * Revert "updating Hashicorp's changes to merged simple linux branch" This reverts commit dbaf8d14a9cdfcef0281919671357f6171ebd4e6. * removing vm from user image example from this branch * removed old branch * azure-2-vms-loadbalancer-lbrules (#13) * initial commit * need to change lb_rule & nic * deploys locally * updated README * updated travis and deploy scripts for Hari's repo * renamed deploy script * clean up * prep for PR * updated readme * fixing conflict in .travis.yml * add CI build tag * initial commit; in progress * in progress * undoing change to readme * in progress * in progress * doesn't winrm * deploys locally * added vars to deploy scripts; removed nsg * chmod * https typo * deploy cleanup * deploys locally * targeting resources for destroy * added graph * removing unmerged example * reverting to Hashicorp's travis.yml * reverting to branch travis.yml before branching to pr to Hashi * reverting to Hashicorp's .travis.yml * clean up

# Create a new VM on a new storage account from a custom image
|
||||
|
||||
This Terraform template was based on [this](https://github.com/Azure/azure-quickstart-templates/tree/master/201-vm-custom-image-new-storage-account) Azure Quickstart Template. Changes to the ARM template that may have occurred since the creation of this example may not be reflected here.
|
||||
|
||||
This template allows you to create a new Virtual Machine from a custom image on a new storage account deployed together with the storage account, which means the source image VHD must be transferred to the newly created storage account before that Virtual Machine is deployed. This is accomplished by the usage of a transfer virtual machine that is deployed and then uses a script via custom script extension to copy the source VHD to the destination storage account. This process is used to overcome the limitation of the custom VHD that needs to reside at the same storage account where new virtual machines based on it will be spun up, the problem arises when you are also deploying the storage account within your template, since the storage account does not exist yet, how can you add the source VHDs beforehand?
|
||||
|
||||
Basically, it creates two VMs, one that is the transfer virtual machine and the second that is the actual virtual machine that is the goal of the deployment. Transfer VM can be removed later.
|
||||
|
||||
The process of this template is:
|
||||
|
||||
1. A Virtual Network is deployed
|
||||
2. Virtual NICs for both Virtual Machines
|
||||
3. Storage Account is created
|
||||
3. Transfer Virtual Machine gets deployed
|
||||
4. Transfer Virtual Machine starts the custom script extension to start the VHD copy from source to destination storage acounts
|
||||
5. The new Virtual Machine based on a custom image VHD gets deployed
|
||||
|
||||
## Requirements
|
||||
|
||||
* A preexisting generalized (sysprepped) Windows image. For more information on how to create custom Windows images, please refer to [How to capture a Windows virtual machine in the Resource Manager deployment model](https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-capture-image/) article.
|
||||
* Source image blob full URL. e.g. https://pmcstorage01.blob.core.windows.net/images/images/Win10MasterImage-osDisk.72451a98-4c26-4375-90c5-0a940dd56bab.vhd. Note that container name always comes after https://pmcstorage01.blob.core.windows.net, in this example it is images. The actual blob name is **images/Win10MasterImage-osDisk.72451a98-4c26-4375-90c5-0a940dd56bab.vhd**.
