Get Apache Airflow on IBM Cloud

We will deploy Apache Airflow on an IBM Cloud Kubernetes Cluster

• Prerequisites :
  • You should have an IBM Cloud account, otherwise you can register here.

1. Provisioning a new Kubernetes Cluster, if already have one skip to step 2
2. Deploying the IBM Cloud Block Storage plug-in, if already have it skip to step 3
3. Deploying Apache Airflow

Step 1 provisioning a new Kubernetes Cluster

• Click the Catalog button on the top
• Select Service from the left in the catalog
• Search for Kubernetes Service and click on it
• At the Kubernetes deployment page, we will specify our deployment details
• Choose a plan standard or free, the free plan only has one worker node and no subnet, to provision a standard cluster, you will need to upgrade you account to Pay-As-You-Go

  • To upgrade to a Pay-As-You-Go account, complete the following steps:

  • In the console, go to Manage > Account.

  • Select Account settings, and click Add credit card.

  • Enter your payment information, click Next, and submit your information

• Choose classic or VPC, read the docs and choose the most suitable type for yourself
• Please decide on your deployment's location parameters , for more information please visit Locations
  • Choose Geography (continent)
  • Choose Single or Multizone, in single zone your data is only kept in one datacenter, with Multizone your data is kept on multiple sites for more security
  • Choose a Worker Zone if using Single zones or Metro if Multizone
    • If you wish to use Multizone please set up your account with VRF or enable Vlan spanning
    • At your current location selection, it is possible there is no Virtual LAN currently available, then a new Vlan will be created for you
• Choose a Worker node setup or use the preselected one, set Worker node amount per zone
• Choose Master Service Endpoint, In VRF-enabled accounts, you can choose private-only to make your master accessible on the private network or via VPN tunnel. Choose public-only to make your master publicly accessible. When you have a VRF-enabled account, your cluster is set up by default to use both private and public endpoints. For more information visit endpoints.
• Give cluster a name

• Give desired tags to your cluster, for more information visit tags

• Click create

• Wait for you cluster to be provisioned

• Your cluster is ready for usage

Step 2 deploy IBM Cloud Block Storage plug-in

The Block Storage plug-in is a persistent, high-performance iSCSI storage that you can add to your apps by using Kubernetes Persistent Volumes (PVs).

• Click the Catalog button on the top

• Select Software from the catalog

• Search for IBM Cloud Block Storage plug-in and click on it

• On the application page Click in the dot next to the cluster, you wish to use

• Click on Enter or Select Namespace and choose the default Namespace or use a custom one (if you get error please wait 30 minutes for the cluster to finalize)

• Give a name to this workspace

• Click install and wait for the deployment

Step 3 Deploy Apache Airflow

In this step we will deploy Apache Airflow on our cluster

• Click the Catalog button on the top

• Select Software from the left in the catalog

• Search for Apache Aifrlow and click on it

• On the application page Click in the dot next to the cluster we just created or use an existing one

• Click on Enter or Select Namespace and choose one of the default Namespaces or use a custom one
