You can deploy GitHub Enterprise Server on global Azure or Azure Government.
- 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 an Azure account capable of provisioning new machines. For more information, see the Microsoft Azure website.
- Most actions needed to launch your virtual machine (VM) may also be performed using the Azure Portal. However, we recommend installing the Azure command line interface (CLI) for initial setup. Examples using the Azure CLI 2.0 are included below. For more information, see Azure's guide "Install Azure CLI 2.0."
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 requirements, your instance will perform and scale better.
|User licenses||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 for the users of your instance, more resources are required.
|8||64 GB||300 jobs|
|16||128 GB||700 jobs|
|32||160 GB||1500 jobs|
|64||256 GB||2500 jobs|
|96||384 GB||4500 jobs|
|128||550 GB||5000 jobs|
For more information about these requirements, see "Getting started with GitHub Actions for GitHub Enterprise Server."
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."
The CPU and memory resources that GitHub Enterprise Server requires depend on the levels of activity for users, automations, and integrations.
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, we recommend 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.
Warning: We recommend that users configure webhook events to notify external systems of activity on GitHub Enterprise Server. Automated checks for changes, or polling, will negatively impact the performance and scalability of your instance. For more information, see "About webhooks."
For more information about monitoring the capacity and performance of GitHub Enterprise Server, see "Monitoring your appliance."
You can increase your instance's CPU or memory resources. For more information, see "Increasing CPU or memory resources."
Before launching your GitHub Enterprise Server instance on Azure, you'll need to determine the machine type that best fits the needs of your organization. For more information about memory optimized machines, see "Memory optimized virtual machine sizes" in the Microsoft Azure documentation. To review the minimum resource requirements for GitHub Enterprise Server, see "Minimum requirements."
Note: You can always scale up your CPU or memory by resizing your instance. However, because resizing your CPU or memory requires downtime for your users, we recommend over-provisioning resources to account for scale.
The GitHub Enterprise Server appliance requires a premium storage data disk, and is supported on any Azure VM that supports premium storage. Azure VM types with the
s suffix support premium storage. For more information, see "What disk types are available in Azure?" and "Azure premium storage: design for high performance" in the Azure documentation.
GitHub recommends a memory-optimized VM for GitHub Enterprise Server. For more information, see "Memory optimized virtual machine sizes" in the Azure documentation.
GitHub Enterprise Server supports any region that supports your VM type. For more information about the supported regions for each VM, see Azure's "Products available by region."
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."
Find the most recent GitHub Enterprise Server appliance image. For more information about the
vm image listcommand, see "
az vm image list" in the Microsoft documentation.
$ az vm image list --all -f GitHub-Enterprise | grep '"urn":' | sort -V
Create a new VM using the appliance image you found. For more information, see "
az vm create" in the Microsoft documentation.
Pass in options for the name of your VM, the resource group, the size of your VM, the name of your preferred Azure region, the name of the appliance image VM you listed in the previous step, and the storage SKU for premium storage. For more information about resource groups, see "Resource groups" in the Microsoft documentation.
$ az vm create -n VM_NAME -g RESOURCE_GROUP --size VM_SIZE -l REGION --image APPLIANCE_IMAGE_NAME --storage-sku Premium_LRS
Configure the security settings on your VM to open up required ports. For more information, see "
az vm open-port" in the Microsoft documentation. See the table below for a description of each port to determine what ports you need to open.
$ az vm open-port -n VM_NAME -g RESOURCE_GROUP --port PORT_NUMBER
This table identifies what each port is used for.
Port Service Description 22 SSH Git over SSH access. Clone, fetch, and push operations to public/private repositories supported. 25 SMTP SMTP with encryption (STARTTLS) support. 80 HTTP Web application access. All requests are redirected to the HTTPS port when SSL is enabled. 122 SSH Instance shell access. The default SSH port (22) is dedicated to application git+ssh network traffic. 161/UDP SNMP Required for network monitoring protocol operation. 443 HTTPS Web application and Git over HTTPS access. 1194/UDP VPN Secure replication network tunnel in high availability configuration. 8080 HTTP Plain-text web based Management Console. Not required unless SSL is disabled manually. 8443 HTTPS Secure web based Management Console. Required for basic installation and configuration. 9418 Git Simple Git protocol port. Clone and fetch operations to public repositories only. Unencrypted network communication. If you have enabled private mode on your instance, then opening this port is only required if you also enabled anonymous Git read access. For more information, see "Enforcing repository management policies in your enterprise."
Create and attach a new unencrypted data disk to the VM, and configure the size based on your user license count. For more information, see "
az vm disk attach" in the Microsoft documentation.
Pass in options for the name of your VM (for example,
ghe-acme-corp), the resource group, the premium storage SKU, the size of the disk (for example,
200), and a name for the resulting VHD.
$ az vm disk attach --vm-name VM_NAME -g RESOURCE_GROUP --sku Premium_LRS --new -z SIZE_IN_GB --name ghe-data.vhd --caching ReadWrite
Note: For non-production instances to have sufficient I/O throughput, the recommended minimum disk size is 150 GiB with read/write cache enabled (
Before configuring the VM, you must wait for it to enter ReadyRole status. Check the status of the VM with the
vm listcommand. For more information, see "
az vm list" in the Microsoft documentation.
$ az vm list -d -g RESOURCE_GROUP -o table > Name ResourceGroup PowerState PublicIps Fqdns Location Zones > ------ --------------- ------------ ------------ ------- ---------- ------- > VM_NAME RESOURCE_GROUP VM running 22.214.171.124 eastus
Note: Azure does not automatically create a FQDNS entry for the VM. For more information, see Azure's guide on how to "Create a fully qualified domain name in the Azure portal for a Linux VM."
Copy the virtual machine's public DNS name, and paste it into a web browser.
At the prompt, upload your license file and set a management console password. For more information, see "Managing your license for GitHub Enterprise."
In the Management Console, configure and save your desired settings. For more information, see "Configuring the GitHub Enterprise Server appliance."
The instance will restart automatically.

GitHub Enterprise Server does not support the installation of Azure extension features. The GitHub Enterprise Server image is shipped with a customized
waagent package which only supports basic VM management functions and blocks advanced VM management functions.
To avoid system instability of your GitHub Enterprise Server instance, the
walinuxagent service is intentionally run in GitHub Enterprise Server in a restricted mode, explicitly disallowing the agent from being able to install other agents. VM management features that rely on additional agents and extensions beyond that which ships with GitHub Enterprise Server image, such as the Monitoring Agent extension for Azure Insights or Azure Backups, are unsupported.
Because GitHub Enterprise Server runs a customized Linux operating system with only the necessary applications and services, installing or updating operating system packages manually will overwrite these customizations and can cause unexpected behavior. For more information, see "System overview."
