      • OS Distribution - choose a preferred OS distribution from the dropdown menu.
      • Disk Type - Standard persistent disks are efficient and practical for handling sequential read/write operations while SSD persistent disks are dedicated to enterprise applications
        and high-performance database needs that demand lower latency and more IOPS.
      • Zone - is a location within a region. Once the 'Region' is selected, then you can define a zone.
      • Machine Type - you can choose from many predefined machine types in each machine type family.
      • Image - select a preferred OS image.
      • Disk Size - provide the disk size in GB.
      • Tags - you may fill in network tags separated by commas or spaces.

    • Custom Machine Settings:

      • Series - Select the custom machine type from available.
      • Number Of Cores - Define the number of cores that will be used.
      • Memory [MB] - Define the allocated memory amount for the machine, use MBs.
    • Client Area Features:

      • Snapshots - enable if you want clients to access the 'Snapshots' section in the client area.
      • Graphs - enable to assure access to the 'Graphs' section in the client area.
    • Network:

  3. At the end of the configuration process, you can decide whether you want to generate configurable options for the product.
    Configurable options can be used by your clients to select each virtual machine parameters individually during order placement.
    Otherwise, if configurable options are not defined, then the fixed parameters specified in the earlier configuration will be used instead.
    If you decide to use configurable options, press on the 'Create Configurable Options' button.

Now, select which options you want to generate and confirm by clicking 'Create'.
Note that the configuration for disabled options will still be taken from the configuration of the main product.
More information about how to use configurable options can be found here or in the official WHMCS documentation (opens new window).
Important: Remember that you may enable either Machine Type configurable option or Custom Machine Series with its sub-options.

# SSH Keys

In the 'Custom Fields' tab you will find the 'SSH Public Key' field which is displayed to clients on the order form by default.
Your SSH key must be an RSA key with a key size of either 2048 bits or 4096 bits.
If you would like to limit the possibility of entering the key e.g. only to the 'ssh-rsa' format, you can use the regular expression in the validation field, such as:

#ssh-rsa AAAA[0-9A-Za-z+/]+[=]{0,3}( [^@]+@[^@]+)?#   

Remember that API allows such action only once, during the initial VM creation.
Note: If you disable the 'Show on Order Form' option, a client will not be able to provide SSH Key while placing an order.

# Importing Existing Instance

In this section, you can find short instruction on how to connect one of your clients to your already existing instance in the Google Cloud panel.
Take the following steps to make sure that the process will be carried out properly.

  1. Firstly, manually create an order for your customer in WHMCS. Choose a client and in the summary, view click on the ' Add New Order' button. Next, select a 'Product/Service' and press 'Submit Order'.
    What is important, do not perform the 'Create' action. The status has to remain as 'Pending'.
    More info about placing orders can be found here (opens new window)

  2. Proceed to the newly created product's card in your admin area. Find the following empty fields:

    • Instance ID
    • Region
    • Zone

    The above-mentioned information has to be consistent with the data from your Google Cloud panel. Now, complete these fields as presented below.
    Important! Remember to make sure that the format of the provided data is compatible with the format supported by the module. You can preview it for another product of the module you have already created and enter it in a similar way.
    If you completed the required data, now change the status from 'Pending' to 'Active' and 'Save Changes'.
