Exporting/Importing AWS EC2 Instance to Oracle Cloud Infrastructure
Prerequisites https://docs.aws.amazon.com/vm-import/latest/userguide/vmexport.html#vmexport-prerequisites
EXPORT RESTRICTIONS ARE AT THE BOTTOM OF THE DOCUMENTATION
Steps (If you have created an EC2 Instance, S3 Bucket, and configured IAM Policies. SKIP to Step 4)
- Create EC2 Instance
- Create S3 Bucket
- Create IAM Groups/Policies
- Add a new Canonical ID to grant access to the Bucket. For all regions in the U.S/Canada your Canonical ID will be (this is also in the documentation linked above): c4d8eabf8db69dbe46bfe0e517100c554f01200b104d59cd408e777ba442a322
- Next you’ll SSH into your EC2 Instance
- Ensure that you’ve installed Pip and Python
- Install and Configure AWS CLI a) https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html b) https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html
Config Example (Ensure you’re in the same region as your instance. Default output format is up to user but for demonstration purposes I chose json)
-
Begin the Export Process a. (Overview) https://docs.aws.amazon.com/vm-import/latest/userguide/vmexport.html#vmexport-limits b. (Create Instance Export Task Example Detailed) https://docs.aws.amazon.com/cli/latest/reference/ec2/create-instance-export-task.html c. Example code: aws ec2 create-instance-export-task --description "RHEL5 instance" --instance-id [instance id] --target-environment vmware --export-to-s3-task DiskImageFormat=vmdk,ContainerFormat=ova,S3Bucket=[bucketname],S3Prefix=RHEL5
-
Your Instance will reboot. It’ll take about 5 min or so for it to upload to S3
-
Download your Instance from S3
-
Log into OCI and Navigate to Object Storage
-
Create your Object Storage bucket and upload your Object
-
Copy the Object URL (DO NOT MAKE A PAR)
-
Navigate to Compute > Custom Images > Import Image
-
Enter information and URL then Import
-
Wait for the Image to Import (Takes 5 – 10 minutes depending on size)
-
Create VCN and ALL related resources
-
After the Custom Image is imported you may create an instance then access it via your SSH. However, you will ssh with @ec2-user instead of @opc but will use the OCI Public IP. Also, to begin any programs on there you will need to use the sudo command to launch. For example if you have a web server. Instead of doing apachectl start, you’ll do sudo apachectl start.
Export Restrictions Exporting instances and volumes is subject to the following limitations: • You cannot export a VM if it contains third-party software provided by AWS. For example, VM Export cannot export Windows or SQL Server instances, or any instance created from an image in the AWS Marketplace. • You must export your instances and volumes to one of the following image formats that your virtualization environment supports: o Open Virtual Appliance (OVA), which is compatible with VMware vSphere versions 4, 5, and 6. o Virtual Hard Disk (VHD), which is compatible with Citrix Xen and Microsoft Hyper-V virtualization products. o Stream-optimized ESX Virtual Machine Disk (VMDK), which is compatible with VMware ESX and VMware vSphere versions 4, 5, and 6. • You can't export Amazon EBS data volumes. • You can't export an instance that has more than one virtual disk. • You can't export an instance that has more than one network interface. • You can't export an instance from Amazon EC2 if you've shared it from another AWS account. • You can't have more than five export tasks per Region in progress at the same time. • VMs with volumes larger than 1 TiB are not supported. • You can export a volume to either an unencrypted S3 bucket or to a bucket encrypted using SSE-S3. You cannot export to an S3 bucket encrypted using SSE-KMS.
