How to specify a flavor, image, keypair, and availability zone for a compute

1. How to specify a flavor & image

  1. In deploy Setup, click on Configure cloud provider.

  2. Choose a matching flavor and image for a compute (e.g., Standard_Ubuntu_18.04_latest | s2.medium.1).

When we designed our HelloWorld application, we specified CPU, RAM, and the operating system for the compute component. However, we did not specify a flavor and image. In the above Figure, the designer shows all available flavors and images that Open Telekom Cloud offers. For examples:

  • If we input 1CPU, 1GB RAM, and the operating system ubuntu for the compute, the designer shows the matching flavor s2.medium.1 and available ubuntu versions: 18.04, 20.04, and 22.04.

  • If we input 3GB RAM, the designer will show the matching flavor s2.medium.4 with 4GB RAM (because Open Telekom Cloud does not offer a flavor with 3GB RAM).

2. How to specify a keypair & availability zone

  1. Select a Compute, the popup shows the following optional properties to configure:

  2. availability_zone: Choose an availability zone for the compute (e.g., eu-de-01).

  3. key_pair: Click on the drop box to show a list of key pairs of the current user. If no key pairs are shown, go to the console of Open Telekom Cloud and create one. Then go back to refresh the keypair list.
