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
- Hardware considerations
- Determining the virtual machine type
- Creating the GitHub Enterprise Server virtual machine
- Configuring the GitHub Enterprise Server virtual machine
You can deploy GitHub Enterprise Server on global Azure or Azure Government.
You must have a GitHub Enterprise license file. To download an existing license file or request a trial license, visit enterprise.github.com. For more information, see "Managing your GitHub Enterprise Server license."
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."
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 user licenses used in your GitHub Enterprise Server instance.
|User licenses||vCPUs||Memory||Attached storage||Root storage|
|Trial, demo, or 10 light users||2||16 GB||100 GB||200 GB|
|10-3000||4||32 GB||250 GB||200 GB|
|3000-5000||8||64 GB||500 GB||200 GB|
|5000-8000||12||96 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. When increasing CPU resources, it's recommended to add at least 6.5 GB of memory for each CPU (up to 16 CPUs) added to your GitHub Enterprise Server instance. For more information, see "Increasing CPU or memory resources."
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."
Recommended VM types
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 user license count, we recommend the following instance types.
|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."
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.
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,
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 (
Configuring the GitHub Enterprise Server virtual machine
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 126.96.36.199 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 GitHub Enterprise Server license."
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.
