Install Astronomer Software on Azure AKS

Install Astronomer Software on Azure to deploy and scale Apache Airflow on a Microsoft Azure Kubernetes Service (AKS) cluster.

Prerequisites​

  • Git
  • Azure CLI
  • Kubernetes CLI (kubectl)
  • A compatible version of Kubernetes and PostgreSQL as described in Astronomer's Version compatibility reference
  • Helm (minimum v3.6)
  • SMTP service and credentials. For example, Mailgun or Sendgrid.
  • Permission to create and modify resources on AKS
  • Permission to generate a certificate (not self-signed) that covers a defined set of subdomains
  • PostgreSQL superuser permissions
  • If your organization uses Azure Database for PostgreSQL as the database backend, you need to enable the pg_trgm extension using the Azure portal or the Azure CLI before you install Astronomer Software. If you don't enable the pg_trgm extension, the install will fail. For more information about enabling the pg_trgm extension, see PostgreSQL extensions in Azure Database for PostgreSQL - Flexible Server.
warning

Astronomer Software is not compatible with Azure Single Server.

Step 1: Choose a base domain​

All Astronomer services will be tied to a base domain of your choice, under which you will need the ability to add and edit DNS records.

Once created, your Astronomer base domain will be linked to a variety of sub-services that your users will access in a browser to manage, monitor and run Airflow on the platform.

For the base domain astro.mydomain.com, for example, here are some corresponding URLs that your users would be able to reach:

  • Software UI: app.astro.mydomain.com
  • Airflow Deployments: deployments.astro.mydomain.com/uniquely-generated-airflow-name/airflow
  • Grafana Dashboard: grafana.astro.mydomain.com
  • Kibana Dashboard: kibana.astro.mydomain.com

For the full list of subdomains, see Step 4.

Step 2: Configure Azure for Astronomer Deployment​

The steps below will walk you through how to:

  • Create an Azure Resource Group
  • Create an AKS Cluster
  • Authenticate with your AKS Cluster

You can view Microsoft Azure's Web Portal at https://portal.azure.com/.

Note: Each version of Astronomer Software is compatible with only a particular set of Kubernetes versions. For more information, refer to Astronomer's Version compatibility reference.

Create an Azure resource group​

A resource group is a collection of related resources for an Azure solution. Your AKS cluster will reside in the resource group you create. Learn more about resource groups here.

Login to your Azure account with the az CLI:

az login

Your active Azure subscriptions will print to your terminal. Set your preferred Azure subscription:

az account set --subscription <subscription_id>

Confirm your preferred subscription is set:

az account show

Create a resource group:

az group create --location <location> --name <my_resource_group>

Note: For a list of available locations, run $ az account list-locations.

Create an AKS cluster​

Once you've created an Azure Resource Group, you can create an AKS cluster using the Azure CLI, Azure PowerShell, or Azure Portal. For instructions, see Microsoft documentation. You can create a cluster with any machine type, but Astronomer recommends using larger nodes and not smaller nodes.

Verify your Kubernetes version is supported by Astronomer Software:

az aks get-versions --location <your-region> --output table

The Kubernetes version returned must be supported by Astronomer Software. See Version compatibility reference.

Create and autoscale your Kubernetes cluster:

az aks create --name <name_of_cluster> --resource-group <your_resource_group> --kubernetes-version <X.X.X> --node-vm-size Standard_D8s_v3 --node-count 3 --enable-cluster-autoscaler --min-count 3 --max-count 10

You may need to increase your resource quota in order to provision these nodes.

Note: If you work with multiple Kubernetes environments, kubectx is an incredibly useful tool for quickly switching between Kubernetes clusters. Learn more here.

Authenticate with your AKS cluster​

Run the following command to set your AKS cluster as current context in your kubeconfig. This will configure kubectl to point to your new AKS cluster:

az aks get-credentials --resource-group <my_resource_group> --name <my_cluster_name>

Step 3: Create a Kubernetes namespace​

Create a namespace called astronomer to host the core Astronomer platform:

kubectl create namespace astronomer

Once Astronomer is running, each Airflow Deployment that you create will have its own isolated namespace.

Step 4: Configure TLS​

Astronomer recommends running Astronomer Software on a dedicated domain (BASEDOMAIN) or subdomain (astro.BASEDOMAIN).

In order for users to access the web applications they need to manage Astronomer, you'll need a TLS certificate that covers the following subdomains:

BASEDOMAIN
app.BASEDOMAIN
deployments.BASEDOMAIN
registry.BASEDOMAIN
houston.BASEDOMAIN
grafana.BASEDOMAIN
kibana.BASEDOMAIN
install.BASEDOMAIN
alertmanager.BASEDOMAIN
prometheus.BASEDOMAIN

To obtain a TLS certificate, complete one of the following setups:

  • Option 1: Obtain a TLS certificate from Let's Encrypt. Astronomer recommends this option for smaller organizations where your DNS administrator and Kubernetes cluster administrator are either the same person or on the same team.
  • Option 2: Request a TLS certificate from your organization's security team. Astronomer recommends this option for large organizations with their own protocols for generating TLS certificates.

Note: Private CAs support on Azure is only available for clusters running containerd 1.5+, which is available on Kubernetes 1.22+.

warning

Astronomer requires you to use RSA to sign TLS certificates. By default, Certbot uses Elliptic Curve Digital Signature Algorithm (ECDSA) keys to sign certificates. If you're using Certbot to sign your TLS certificate, you must include -key-type rsa --rsa-key-size 2048 in your command to sign your certificate with an RSA key. If you don't use RSA keys, deploys fail and error messages appear in the registry and Houston logs. For example, you can run the following command to sign your certificate with an RSA key:

sudo certbot certonly --manual --preferred-challenges=dns -d -d *. --key-type=rsa

Option 1: Create TLS certificates using Let's Encrypt​

Let's Encrypt is a free and secure certificate authority (CA) service that provides TLS certificates that renew automatically every 90 days. Use this option if you are configuring Astronomer for a smaller organization without a dedicated security team.

To set up TLS certificates this way, follow the guidelines in Automatically Renew TLS Certificates Using Let's Encrypt. Make note of the certificate you create in this setup for Step 5.

Option 2: Request a TLS certificate from your security team​

If you're installing Astronomer for a large organization, you'll need to request a TLS certificate and private key from your enterprise security team. This certificate needs to be valid for the BASEDOMAIN your organization uses for Astronomer, as well as the subdomains listed at the beginning of Step 4. You should be given two .pem files:

  • One for your encrypted certificate
  • One for your private key

To confirm that your enterprise security team generated the correct certificate, run the following command using the openssl CLI:

openssl x509 -in  <your-certificate-filepath> -text -noout

This command will generate a report. If the X509v3 Subject Alternative Name section of this report includes either a single *.BASEDOMAIN wildcard domain or the subdomains listed at the beginning of Step 4, then the certificate creation was successful.

Depending on your organization, you may receive either a globally trusted certificate or a certificate from a private CA. The certificate from your private CA may include a domain certificate, a root certificate, and/or intermediate certificates, all of which need to be in proper certificate order. To verify certificate order, follow the guidelines below.

Confirm certificate chain order​

If your organization is using a private certificate authority, you'll need to confirm that your certificate chain is ordered correctly. To determine your certificate chain order, run the following command using the openssl CLI:

openssl crl2pkcs7 -nocrl -certfile <your-certificate-filepath> | openssl pkcs7 -print_certs -noout

The command generates a report of all certificates. Verify the order of the certificates is as follows:

  • Domain
  • Intermediate (optional)
  • Root

If the certificate order is correct, proceed to step 5.

Step 5: Create a Kubernetes TLS Secret​

If you received a globally trusted certificate, such as one generated by Let's Encrypt, simply run the following command and proceed to Step 6:

kubectl create secret tls astronomer-tls --cert <your-certificate-filepath> --key <your-private-key-filepath> -n astronomer

If you received a certificate from a private CA, follow these steps instead:

  1. Add the root certificate provided by your security team to an Opaque Kubernetes secret in the Astronomer namespace by running the following command:

    kubectl create secret generic private-root-ca --from-file=cert.pem=./<your-certificate-filepath> -n astronomer

    Note: The root certificate which you specify here should be the certificate of the authority that signed the Astronomer certificate, rather than the Astronomer certificate itself. This is the same certificate you need to install with all clients to get them to trust your services.

    Note: The name of the secret file must be cert.pem for your certificate to be trusted properly.

  2. Note the value of private-root-ca for when you configure your Helm chart in Step 8. You'll need to additionally specify the privateCaCerts key-value pair with this value for that step.

Step 6: Configure your SMTP URI​

An SMTP service is required for sending and accepting email invites from Astronomer. If you're running Astronomer Software with publicSignups disabled (which is the default), you'll need to configure SMTP as a way for your users to receive and accept invites to the platform through an email invitation. To integrate your SMTP service with Astronomer, fetch your SMTP service's URI and store it in a Kubernetes secret:

kubectl create secret generic astronomer-smtp --from-literal connection="smtp://USERNAME:PASSWORD@HOST/?requireTLS=true" -n astronomer

In general, an SMTP URI will take the following form:

smtps://USERNAME:PASSWORD@HOST/?pool=true

The following table contains examples of what the URI will look like for some of the most popular SMTP services:

ProviderExample SMTP URL
AWS SESsmtp://AWS_SMTP_Username:AWS_SMTP_Password@email-smtp.us-east-1.amazonaws.com/?requireTLS=true
SendGridsmtps://apikey:SG.sometoken@smtp.sendgrid.net:465/?pool=true
Mailgunsmtps://xyz%40example.com:password@smtp.mailgun.org/?pool=true
Office365smtp://xyz%40example.com:password@smtp.office365.com:587/?requireTLS=true
Custom SMTP-relaysmtp://smtp-relay.example.com:25/?ignoreTLS=true

If your SMTP provider is not listed, refer to the provider's documentation for information on creating an SMTP URI.

Note: If there are / or other escape characters in your username or password, you may need to URL encode those characters.

Step 7: Configure the database​

If you're connecting to an external database, you will need to create a secret named astronomer-bootstrap to hold your database connection string:

kubectl create secret generic astronomer-bootstrap \
  --from-literal connection="postgres://USERNAME:$PASSWORD@host:5432" \
  --namespace astronomer

Note: You must URL encode any special characters in your Postgres password.

A few additional configuration notes:

  • If you provision an external database, postgresqlEnabled should be set to false in Step 8. The in-cluster database should be used only for development or proof-of-concept installations. All production installations should use an external database.
  • If your organization uses Azure Database for PostgreSQL as the database backend, you need to enable the pg_trgm extension using the Azure portal or the Azure CLI before you install Astronomer Software. If you don't enable the pg_trgm extension, the install will fail. For more information about enabling the pg_trgm extension, see PostgreSQL extensions in Azure Database for PostgreSQL - Flexible Server.
  • If you provision Azure Database for PostgreSQL - Flexible Server, it enforces TLS/SSL and requires that you set sslmode to prefer in your values.yaml.

Step 8: Configure Your Helm chart​

info

To use a third-party ingress controller for Astronomer, see Third-Party Ingress Controllers.

As a next step, create a file named values.yaml in an empty directory.

For context, this values.yaml file will assume a set of default values for our platform that specify everything from user role definitions to the Airflow images you want to support. As you grow with Astronomer and want to customize the platform to better suit your team and use case, your values.yaml file is the best place to do so.

In the newly created file, copy the example below and replace baseDomain, private-root-ca, /etc/containerd/certs.d, and astronomer.houston.secret with your own values. For more example configuration files, see the Astronomer GitHub.

Note: If there are / or other escape characters in your username or password, you may need to URL encode those characters.

These are the minimum values you need to configure for installing Astronomer. For information on additional configuration, read What's Next.

info

If you are installing Astronomer in an airgapped environment without access to the public internet, complete all of the setup in Install in an Airgapped Environment and then skip directly to Step 10 in this document.

Step 9: Install Astronomer​

Now that you have an AKS cluster set up and your values.yaml defined, you're ready to deploy all components of our platform.

First, run:

helm repo add astronomer https://helm.astronomer.io/

Then, run:

helm repo update

This ensures that you pull the latest image from the Astronomer Helm repository. Now, run:

helm install -f values.yaml --version=0.34 --namespace=astronomer <your-platform-release-name> astronomer/astronomer

This command installs the most recent patch version of Astronomer Software. To install a different patch version, add the --version= flag and use the format 0.34.x. For example, to install Astronomer Software v0.34.0, you specify --version=0.34.0. For more information about the available patch versions, see the Software Release Notes.

When you're defining <your-platform-release-name>, Astronomer recommends limiting the name to 12 characters to avoid operational issues.

After you run the previous commands, a set of Kubernetes pods are generated in your namespace. These pods power the individual services required to run the Astronomer platform, including the Software UI and Houston API.

Alternative ArgoCD installation​

You can install Astronomer with ArgoCD, which is an open source continuous delivery tool for Kubernetes, as an alternative to using helm install.

Because ArgoCD doesn't support sync wave dependencies for app of apps structures, installing Astronomer requires some additional steps compared to the standard ArgoCD workflow:

  1. Under the global section of your values.yaml file, add enableArgoCDAnnotation: true.

  2. Create a new ArgoCD app. When creating the app, configure the following:

    • Path: The filepath of your values.yaml file
    • Namespace: The namespace you want to use for Astronomer
    • Cluster: The Kubernetes cluster in which you're installing Astronomer
    • Repository URL: https://helm.astronomer.io

  3. Sync the ArgoCD app with every component of the Astronomer platform selected. See Sync (Deploy) the Application.

  4. Stop the sync when you see that astronomer-houston-db-migrations has completed in the Argo UI.

  5. Sync the application a second time, but this time clear astronomer-alertmanager in the Argo UI while keeping all other components selected. Wait for this sync to finish completely.

  6. Sync the ArgoCD app a third time with all Astronomer platform components selected.

Step 10: Verify all pods are up​

To verify all pods are up and running, run:

kubectl get pods --namespace astronomer

You should see something like this:

$ kubectl get pods --namespace astronomer

Step 11: Configure DNS​

Now that you've successfully installed Astronomer, a new Load Balancer will have spun up in your Azure account. This Load Balancer routes incoming traffic to our NGINX ingress controller.

Run kubectl get svc -n astronomer to view your Load Balancer's External IP Address, located under the EXTERNAL-IP column for the astronomer-nginx service.

$ kubectl get svc -n astronomer

You will need to create a new A record through your DNS provider using the external IP address listed above. You can create a single wildcard A record such as *.astro.mydomain.com, or alternatively create individual A records for the following routes:

app.astro.mydomain.com
deployments.astro.mydomain.com
registry.astro.mydomain.com
houston.astro.mydomain.com
grafana.astro.mydomain.com
kibana.astro.mydomain.com
install.astro.mydomain.com
alertmanager.astro.mydomain.com
prometheus.astro.mydomain.com

Step 12: Verify you can access the Software UI​

Go to app.BASEDOMAIN to see the Software UI.

Consider this your new Airflow control plane. From the Software UI, you'll be able to both invite and manage users as well as create and monitor Airflow Deployments on the platform.

Step 13: Verify your TLS setup​

To check if your TLS certificates were accepted, log in to the Software UI. Then, go to app.BASEDOMAIN/token and run:

curl -v -X POST https://houston.BASEDOMAIN/v1 -H "Authorization: Bearer <token>"

Verify that this output matches with that of the following command, which doesn't look for TLS:

curl -v -k -X POST https://houston.BASEDOMAIN/v1 -H "Authorization: Bearer <token>"

Next, to make sure the registry is accepted by Astronomer's local docker client, try authenticating to Astronomer with the Astro CLI:

astro auth login <your-astronomer-base-domain>

If you can log in, then your Docker client trusts the registry. If Docker does not trust the Astronomer registry, run the following and restart Docker:

$ mkdir -p /etc/docker/certs.d
$ cp privateCA.pem /etc/docker/certs.d/

Finally, try running $ astro deploy on a test deployment. Create a deployment in the Software UI, then run:

$ mkdir demo
$ cd demo
$ astro dev init --use-astronomer-certified
$ astro deploy -f

Check the Airflow namespace. If pods are changing at all, then the Houston API trusts the registry.

If you have Airflow pods in the state ImagePullBackoff, check the pod description. If you see an x509 error, ensure that you have:

  • Configured containerd’s config_path to point to /etc/containerd/certs.d.
  • Added the privateCaCertsAddToHost key-value pairs to your Helm chart.

If you missed these steps during installation, follow the steps in Apply a config change to add them after installation. If you are using a base image such as CoreOS that does not permit values to be changed, or you otherwise can't modify values.yaml, contact Astronomer support for additional configuration assistance.
