AWS CDK - Lightsail Database High Availability

[marcotondi]

Hi folk,

I am implementing my infrastructure on Amazon Lightsail using CDK. From the Lightsail console, it is possible to create a high availability database by setting the option dedicate.
I would like to understand how to achieve the same result using CDK.

I have found the Amazon Lightsail documentation for setting up a high availability database, but I have not been able to find a solution for CDK.

Could anyone help?

Thanks in advance,
Marco

I'm not sure if any of the options available in CloudFormation are sufficient - I can't tell if this option is available in the API either. I can't find a way to set this in any of the commands in the API reference for Lightsail.

If there isn't any way to do this through CloudFormation, then you would need to implement a custom resource like AwsCustomResource to make the API call with the properties you need. However, if it's not supported in the API, then I don't think there would be any way to do this through CDK.

I hoped you hadn't seen all the options properly :)

I thank you for the answer.

Hi,
I found a solution to do this!!!
To have the Lightsail database in high reliability it is managed through the configuration of the relationshipDatabaseBundleId key in CDK (e.g.: medium_2_0 - > medium_ha_2_0).
