Import your own custom Image¶
In the E2E cloud stack, we empower our customers by allowing them to get their customized images made available in their myaccount console. Customers can bring in their golden images (customized Linux/Windows distributions with software and configurations to fit the specific needs) from the on-premises environment or even from other cloud providers to the E2E cloud platform and use them to create virtual machines with their choice of Plans. | The option saves time and effort required to set up and configure your node right from the scratch again to get your required golden stack in place. You can get your bootable disk images from virtual machines (VMs) on your local workstation, from your physical datacenters, or from VMs that run on another cloud platform to E2E Cloud-Platform.
VM initialization method¶
There are different methods to pass information to a newly created Virtual Machine. This information can be the network configuration of the VM, user credentials, init scripts, and free form data.
In our cloud platform, we use the OpenNebula context package for virtual machine initialization, which configures the network, sets the user credentials, sets hostname, adds provided SSH keys, etc.
Download and Installation of Contextualization Packages and Dependencies to your VM¶
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context-5.8.0-1.el6.noarch.rpm # yum install -y epel-release # yum install -y one-context-[0-9]*el6*rpm
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context-5.8.0-1.el7.noarch.rpm # yum install -y epel-release # yum install -y one-context-[0-9]*el7*rpm
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context_5.8.0-1.deb # apt-get purge -y cloud-init # dpkg -i one-context_*deb || apt-get install -fy
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context-5.8.0-1.suse.noarch.rpm # zypper --no-gpg-check install -y one-context-[0-9]*suse*rpm
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context-5.8.0-r1.apk # apk add --allow-untrusted one-context-[0-9]*apk
# wget https://github.com/OpenNebula/addon-context-linux/releases/download/v5.8.0/one-context-5.8.0_1.txz # pkg install -y curl bash sudo base64 ruby open-vm-tools-nox11 # pkg install -y one-context-[0-9]*.txz
Download the MSI package into
Or execute this command in powershell:
(New-Object Net.WebClient).DownloadFile("https://github.com/OpenNebula/addon-context-windows/releases/download/v5.8.0/one-context-5.8.0.msi", "C:\one-context-5.8.0.msi")
Double-click on the downloaded MSI package icon in the same way you open other documents to install it.
If you have cloud-init present in your virtual machine for initialization, please make sure that the respective cloud-init service is disabled on boot before taking the image. The cloud-init will conflict with the OpenNebula context package which may result in failure of virtual machine initialization process.
Supported image formats¶
E2E cloud-platform supports images in qcow2, qed, raw, vdi, vhd, and vmdk formats for import.
To save space and reduce import time you can also compress the file using gzip and tar compression formats.
The image should contain single disk partition. The primary partition on the disk can be in any format that you like as long as it boots properly from the MBR bootloader. The disk should not be larger than 2048 GB (2 TB).
Operating System requirements¶
- CentOS/RHEL >= 6
- Debian >= 8
- Ubuntu >= 14.04
- Windows Server >= 2012
Other operating systems can also be imported but they might require additional configuration steps that are not covered in this guide.
Importing an image to E2E Cloud-Platform¶
- Go to MyAccount and log in using your credentials set up at the time of creating and activating the My Account.
- On the left Navigation bar, Select Compute available under the product section.
- You will redirect to the Manage Node page.
- Click on the ‘Saved Image’.
- You will redirect to the ‘Manage Saved Image’ page.
- Click on the ‘Import Custom Image’.
- The import custom image window will be opened. Please provide the following details.
The imported image will be saved in a format specific to our environment. This means that the actual size of the image stored in our system can be different from the size of the image as visible in your environment. This difference can sometimes be as high as 5 times the original size. Please contact us at firstname.lastname@example.org
Public URL: Enter the URL (downloadable link) of the image you want to use in this text field. We will import the image file from a specified link.
You can upload your image to the file-sharing tool and make the file public like Dropbox. Make sure the URL ends in the file extension (like example.com/file.raw instead of example.com/file.raw?dl=0).
Custom Image Name: This field is pre-filled with the name, but you can customize it if you like to use it to import a custom saved image.
- After you’ve entered the required details, click Import. An information message will appear on screen.
Importing virtual images will take some time. It’s depending upon the size of an image. You will be notified once an image is imported.
- Once your custom image is added to your account, you can create a node or create a scale group from your custom image.
- You can contact our cloud-platform support team at email@example.com for any query and concern with the import process.
