Azure

This page describes the infrastructure and other prerequisites for deploying Seqera Platform Enterprise on Microsoft Azure.

Run the Seqera container images with Docker on an Azure VM instance or with Kubernetes on an Azure AKS cluster. You must satisfy the requirements for your installation target:

• A resource group and a storage account are required to use Azure. See Azure setup below to provision these resources.

• SMTP server: If you don't have an email server, see Azure's recommended method of sending email. Microsoft recommends Microsoft 365 or the third party service SendGrid.

• MySQL database: An external database such as Azure Database for MySQL is highly recommended for production deployments.

• Redis-compatible cache: An external Redis-compatible cache, such as Azure Cache for Redis, is highly recommended for production deployments.

• SSL certificate: An SSL certificate is required for your Seqera instance to handle HTTPS traffic.

  caution

  HTTP-only implementations must set the TOWER_ENABLE_UNSAFE_MODE=true environment variable in the Seqera hosting infrastructure to enable user login. HTTP must not be used in production environments.

• DNS: (Optional) DNS is required to support human-readable domain names and load-balanced traffic. See Azure DNS to learn about domain aquisition and record management.

These decisions must be made before you continue as they impact how Seqera configuration files are updated.

Prerequisites for Docker

A Linux VM instance is required to deploy Seqera Enterprise via Docker Compose. See the detailed instructions to provision a VM instance for this purpose.

Prerequisites for AKS

An Azure Kubernetes Service (AKS) cluster is required to deploy Seqera Enterprise via Kubernetes.

Azure setup

Set up commonly used Azure services for Seqera deployment.

Azure resource group

Create a resource group:

• Via the Azure portal
• Via the Azure CLI

Create a resource group via Azure portal

1. Sign in to the Azure portal.
2. Select Resource groups.
3. Select Add.
4. Enter the following values:
   • Subscription: Select your Azure subscription.
   • Resource group: Enter a new resource group name (such as towerrg).
   • Region: Select the region where your assets will exist (such as East US).
5. Select Review and Create.
6. Select Create.

Create a resource group via Azure CLI

Run the az group create command:

az group create --name $MY_RESOURCE_GROUP_NAME --location $REGION

Azure storage account

Create a storage account:

• Via the Azure portal
• Via the Azure CLI

Create a storage account via Azure portal

1. Sign in to the Azure portal.
2. Select Storage accounts.
3. Select Create.
4. Enter the following values:
   • Subscription: Select your Azure subscription.
   • Resource group: Enter your resource group name.
   • Storage account name: Enter a new storage account name (such as towerstorage).
   • Region: Select the region where your Resource Group exists (such as East US).
   • Performance: Select Standard.
   • Redundancy: Select Geo-redundant storage (GRS).
5. Select Review + create. The default values are used in the other tabs. See Create a storage account for further details on each setting.
6. Select Create.

Create a storage account via Azure CLI

Run the az storage account create command:

az storage account create -n towerstorage -g towerrg -l eastus --sku Standard_GRS

Azure MySQL DB instance

External databases for Seqera Enterprise deployments require:

• A MySQL8 Community DB instance.
• At least 2 vCPUs, 8 GB memory, and 30 GB SSD storage.
• Manual MySQL user and database schema creation. See Database configuration for more details.

caution

Recommended instance performance and storage requirements depend on the number of parallel pipelines you expect to run.

Create an Azure MySQL DB instance:

• Via Azure portal
• Via Azure CLI

Create a MySQL DB instance via Azure portal

1. In the Azure portal, search for and select Azure Database for MySQL servers.
2. Select Create.
3. On the Select Azure Database for MySQL deployment option pane, select Flexible server as the deployment option.
4. On the Basics tab, enter or select the following:
   • Your Subscription name
   • Your Resource group name
   • A Server name such as towerdbserver
   • Your Region
   • The Workload type, based on your required max_connections
   • High availability — high availability is recommended for production deployments
   • Standby availability zone — standby server zone location
   • MySQL version — 8.0
   • An Admin username to access the server
   • A Password to access the server
   • Your Compute + storage requirements, considering the minimum performance requirements outlined above
5. Configure networking options.
6. Select Review + create, then Create.
7. Disable invisible primary keys, which can interfere with upgrades to newer releases of Seqera Platform Enterprise. Azure Database for MySQL creates invisible primary keys automatically by default. For more information, see Steps to disable a GIPK.

Create a MySQL DB instance via Azure CLI

1. Run az mysql flexible-server create to create your server:

   az mysql flexible-server create --location eastus --resource-group towerrg --name towerdbserver --admin-user username --admin-password password --sku-name Standard_B2ms --tier Burstable --public-access 0.0.0.0 --storage-size 30 --version 8.0 --high-availability ZoneRedundant --zone 1 --standby-zone 3 --storage-auto-grow Enabled --iops 500

   The sku-name, tier, storage-size, and iops values depend on your performance requirements.

2. Run az mysql flexible-server db create to create a database on your server:

   az mysql flexible-server db create --resource-group towerrg
                                   --server-name towerdbserver
                                   --database-name towerdb

3. Disable invisible primary keys, which can interfere with upgrades to newer releases of Seqera Platform Enterprise. Azure Database for MySQL creates invisible primary keys automatically by default. For more information, see Steps to disable a GIPK.

After your database is created, update your Seqera configuration with the database hostname, Admin username, and password.

note

When creating a MySQL user, use the USER@HOSTNAME format for the TOWER_DB_USER environment variable. For Azure managed MySQL, it's recommended to pass an explicit serverTimezone to the TOWER_DB_URL environment variable, which (depending on your configuration) may be UTC. The DB connection string should be similar to jdbc:mysql://towerdbserver.mysql.database.azure.com/towerdb?serverTimezone=UTC.

Azure Linux VM

Create a VM instance with these attributes:

• Use default values unless otherwise specified.
• At least 2 CPUS and 8GB RAM.

• Accessible by SSH.

Create an Azure Linux VM:

• Via the Azure portal
• Via the Azure CLI

Create a VM via Azure portal

1. Under Basics, select your Subscription and Resource group.
2. Under Instance details:
   • Enter a VM name
   • Select the same Region as your resource group.
   • Select the Ubuntu Server 24.04 LTS - Gen2 image.
   • Do not set the VM as an Azure Spot instance.

To make the VM's IP address static:

1. Enter Public IP addresses in the search.
2. Under Services, select Public IP addresses.
3. On the Public IP addresses page, select the entry containing your VM name. A page opens with that IP's details.
4. Select Configuration from the left-hand navigation panel.
5. Confirm that your IP address assignment is Static.
6. Do not add a custom DNS name label to the VM.

To allow ingress on port 8000:

1. Enter Virtual Machines in the search bar.
2. Under Services, select Virtual machines.
3. On the Virtual machines page, select your VM name to navigate to the VM details.
4. Select Networking from the left-hand navigation panel.
5. Add inbound port rule for port 8000.

To allow ingress on port 443 (required for SSL/TLS termination in production environments):

2. Install Docker:

   1. Install Docker using the apt repository.

   2. Confirm that Docker Compose is installed:

      docker compose version
      Docker Compose version v2.24.1

Create a VM via Azure CLI

Run az vm create:

az vm create \
  --resource-group towerrg \
  --name towervm \
  --image Canonical:0001-com-ubuntu-minimal-jammy:minimal-22_04-lts-gen2:latest \
  --admin-username username \
  --assign-identity \
  --generate-ssh-keys \
  --public-ip-sku Standard

Seqera container images

Seqera Enterprise is distributed as a collection of container images available through the Seqera container registry cr.seqera.io. Refer to the instructions in the Common prerequisites page to replicate the required images to your internal container registry for High Availability or for air-gapped environments.
