Instalar o GitHub Enterprise Server no Hyper-V

Prerequisites

• You must have a GitHub Enterprise license file. For more information, see "Setting up a trial of GitHub Enterprise Server" and "About licenses for GitHub Enterprise."
• You must have Windows Server 2008 through Windows Server 2022, which supports Hyper-V.
• Most actions needed to create your virtual machine (VM) may also be performed using the Hyper-V Manager. However, we recommend using the Windows PowerShell command-line shell for initial setup. Examples using PowerShell are included below. For more information, see the Microsoft guide Getting Started with Windows PowerShell.

Hardware considerations

• Minimum recommended requirements
• Storage
• CPU and memory

Minimum recommended requirements

We recommend different hardware configurations depending on the number of user licenses for your GitHub Enterprise Server instance. If you provision more resources than the minimum recommended requirements, your instance will perform and scale better.

User licenses	x86-64 vCPUs	Memory	Root storage	Attached (data) storage
Trial, demo, or 10 light users	4	32 GB	200 GB	150 GB
10 to 3,000	8	48 GB	200 GB	300 GB
3,000 to 5000	12	64 GB	200 GB	500 GB
5,000 to 8000	16	96 GB	200 GB	750 GB
8,000 to 10,000+	20	160 GB	200 GB	1000 GB

If you plan to enable GitHub Actions or GitHub Advanced Security for the users of your instance, more resources are required.

• GitHub Actions - increase CPU and memory by 25%
• GitHub Advanced Security - increase CPU and memory by 15%

These adjustments should be applied to the base requirements for each user tier.

For more information about these requirements, see "Getting started with GitHub Actions for GitHub Enterprise Server."

If you plan to enable Container registry for the users of your instance, more resources are required. For more information about these requirements, see "Getting started with GitHub Packages for your enterprise."

For more information about adjusting resources for an existing instance, see "Increasing storage capacity" and "Increasing CPU or memory resources."

Storage

We recommend a high-performance SSD with high input/output operations per second (IOPS) and low latency for GitHub Enterprise Server. Workloads are I/O intensive. If you use a bare metal hypervisor, we recommend directly attaching the disk or using a disk from a storage area network (SAN).

Your instance requires a persistent data disk separate from the root disk. For more information, see "System overview."

To configure GitHub Actions, you must provide external blob storage. For more information, see "Getting started with GitHub Actions for GitHub Enterprise Server."

The available space on the root filesystem will be 50% of the total disk size. You can resize your instance's root disk by building a new instance or using an existing instance. For more information, see "System overview" and "Increasing storage capacity."

CPU and memory

The CPU and memory resources that GitHub Enterprise Server requires depend on the levels of activity for users, automations, and integrations.

Any VMs you provision for your GitHub Enterprise Server instance must use the x86-64 CPU architecture. Other architectures are not supported, such as AArch64 or arm64.

If you plan to enable GitHub Actions for the users of your GitHub Enterprise Server instance, you may need to provision additional CPU and memory resources for your instance. For more information, see "Getting started with GitHub Actions for GitHub Enterprise Server."

When you increase CPU resources, GitHub recommends adding at least 6.5 GB of memory for each vCPU (up to 16 vCPUs) that you provision for the instance. When you use more than 16 vCPUs, you don't need to add 6.5 GB of memory for each vCPU, but you should monitor your instance to ensure it has enough memory.

For more information about monitoring the capacity and performance of GitHub Enterprise Server, see "Monitoring your instance."

You can increase your instance's CPU or memory resources. For more information, see "Increasing CPU or memory resources."

Downloading the GitHub Enterprise Server image

1. Download your license. For more information, see "Downloading your license for GitHub Enterprise."

2. Navigate to the image you want to use for your new instance.

   • Navigate to Release notes.
   • In the right sidebar, click the version you want to download.
   • Click Download GitHub Enterprise Server X.X.X.

3. Under "GitHub On-premises", select the "Select your hypervisor" dropdown menu and click Hyper-V (VHD).

4. Click Download for Hyper-V (VHD).

Creating the GitHub Enterprise Server instance

To create the instance, you'll need to import the GitHub Enterprise Server image to your virtual machine and attach an additional storage volume for your instance data. For more information, see "Hardware considerations."

1. In PowerShell, create a new Generation 1 virtual machine, configure the size based on your user license count, and attach the GitHub Enterprise Server image you downloaded. For more information, see New-VM in the Microsoft documentation.

   PS C:\> New-VM -Generation 1 -Name VM_NAME -MemoryStartupBytes MEMORY_SIZE -BootDevice VHD -VHDPath PATH_TO_VHD  
   

2. Create a new virtual disk to use as an attached storage volume for your instance data, and configure the size based on your user license count. If reusing an existing disk, ensure that the disk is empty and there are no partitions. Replace PATH_TO_DATA_DISK with the path to the location where you create the disk. For more information, see "New-VHD" in the Microsoft documentation.

   PS C:\> New-VHD -Path PATH_TO_DATA_DISK -SizeBytes DISK_SIZE
   

3. Attach the data disk to your instance. For more information, see Add-VMHardDiskDrive in the Microsoft documentation.

   PS C:\> Add-VMHardDiskDrive -VMName VM_NAME -Path PATH_TO_DATA_DISK
   

4. Start the VM. For more information, see Start-VM in the Microsoft documentation.

   PS C:\> Start-VM -Name VM_NAME
   

5. Get the IP address of your VM. For more information, see Get-VMNetworkAdapter in the Microsoft documentation.

   PS C:\> (Get-VMNetworkAdapter -VMName VM_NAME).IpAddresses
   

6. Copy the VM's IP address and paste it into a web browser.

Configuring the GitHub Enterprise Server instance

To configure the instance, you must upload a license file, set the root Management Console password, configure the instance's settings, and restart the instance.

1. Copy the virtual machine's public DNS name, and paste it into a web browser.
2. At the prompt, upload your license file and set a management console password. For more information, see "Managing your license for GitHub Enterprise."
3. In the Management Console, configure and save your desired settings. For more information, see "Configuring GitHub Enterprise."
4. The instance will restart automatically.
5. Click Visit your instance.
