This version of GitHub Enterprise will be discontinued on This version of GitHub Enterprise was discontinued on 2019-03-27. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise. For help with the upgrade, contact GitHub Enterprise support.

Installing GitHub Enterprise Server on Azure

To install GitHub Enterprise Server on Azure, you must deploy onto a DS-series instance and use Premium-LRS storage.

In this guide

You can deploy GitHub Enterprise Server on global Azure or Azure Government.

Prerequisites

Hardware considerations

GitHub Enterprise Server requires a persistent data disk separate from the root disk. For more information, see "System overview."

We recommend different hardware configurations based on the number of seats used in your GitHub Enterprise Server instance.

Seats vCPUs Memory Attached storage Root storage
10-500 2 16 GB 100 GB 200 GB
500-3000 4 32 GB 250 GB 200 GB
3000-5000 8 64 GB 500 GB 200 GB
5000-8000 12 72 GB 750 GB 200 GB
8000-10000+ 16 128 GB 1000 GB 200 GB

These are minimum recommendations. More resources may be required depending on your usage, such as user activity and selected integrations.

Note: The root disk can be resized by building a new appliance or using an existing appliance. For more information, see "Increasing storage capacity."

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. For more information, see "About webhooks"

Determining the virtual machine type

Before launching your GitHub Enterprise Server instance on Azure, you'll need to determine the type of virtual machine that best fits the needs of your organization.

Supported VM types and regions

The GitHub Enterprise Server appliance requires a premium storage data disk, and is supported on any Azure VM that supports premium storage. For more information, see "Supported VMs" in the Azure documentation. For general information about available VMs, see the Azure virtual machines overview page.

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."

We recommend you use a DS v2 instance type with at least 14 GB of RAM. You can use any supported VM type. Based on your seat count, we recommend the following instance types.

Seats Recommended type
10 - 500 Standard_DS11_v2
500 - 3000 Standard_DS12_v2
3000 - 8000 Standard_DS14_v2
8000 - 10000+ Standard_DS15_v2

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.

Creating the GitHub Enterprise Server virtual machine

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. Find the most recent GitHub Enterprise Server appliance image. For more information about the vm image list command, see "az vm image list" in the Microsoft documentation.

    $ az vm image list --all -f GitHub-Enterprise | grep '"urn":' | sort -V
  2. 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
  3. 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.
  4. Create and attach a new unencrypted data disk to the VM, and configure the size based on your seat 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, 100), 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 --disk ghe-data.vhd

Note: For non-production instances to have sufficient I/O throughput, the recommended minimum disk size is 40 GiB with read/write cache enabled (--caching ReadWrite).

Configuring the GitHub Enterprise Server virtual machine

  1. Before configuring the VM, you must wait for it to enter ReadyRole status. Check the status of the VM with the vm list command. 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    40.76.79.202           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."

  2. Copy the virtual machine's public DNS name, and paste it into a web browser.

  3. At the prompt, upload your license file and set a management console password. For more information, see "About license files."

  4. In the Management Console, configure and save your desired settings. For more information, see "Configuring the GitHub Enterprise Server appliance."

  5. The instance will restart automatically.

  6. Click Visit your instance.
