To install GitHub Enterprise on Hyper-V, you must have a machine running Windows 8 Pro or Windows 8 Enterprise and then deploy the GitHub Enterprise disk image to it.
Requirements
Before installing GitHub Enterprise on Hyper-V, ensure you meet these software and hardware requirements.
Software
- GitHub Enterprise Hyper-V disk image (VHD) and license files - The appliance and license required to run GitHub Enterprise are available from the GitHub Enterprise download page.
- Windows 8 Pro or Windows 8 Enterprise - Both of these operating systems support Hyper-V servers.
- Hyper-V Manager - This software provides a graphical interface for configuring Hyper-V servers.
Hardware
- For your root storage, we require at least an 80 GB virtual disk.
- For your attached storage device, we recommend a high-performance disk, such as a SAN or a local SSD.
Based on your seat count, we recommend this hardware configuration:
| Seats | vCPUs | Memory | Attached Storage | Root Storage |
|---|---|---|---|---|
| 0-500 | 2 | 16 GB | 100 GB | 80 GB |
| 500-3000 | 4 | 32 GB | 250 GB | 80 GB |
| 3000-5000 | 8 | 64 GB | 500 GB | 80 GB |
These are minimum recommendations and more resources may be required depending on your usage.
Note: The root disk cannot be resized.
Warning: We recommend you use webhooks to fetch repository changes for continuous integration (CI) or similar systems. Regular automatic checks, or polling, will significantly reduce the scalability of your instance.
An encrypted data volume provides an extra level of security by ensuring that any data you write to your instance is protected. There's a slight peformance impact when using encrypted disks. If you decide to encrypt your volume, we strongly recommend doing so before starting your instance for the first time. For more information, see the documentation on BitLocker Drive Encryption.
If you decide to enable encryption after you've configured your instance, you will need to migrate your data to the encrypted volume, which will incur some downtime for your users.
