About this blueprint
System
This system flow copies flows from the current tenant to a new Kestra tenant or environments. The pattern shown here is particularly useful if you want to automatically promote flows from development to QA and staging environments or tenants. Here, we release development flows to a staging tenant every day at 5 PM.
The flow is composed of the following tasks:
- Download flows from the source tenant using the
Downloadplugin. - Import flows into the target tenant using the
Requestplugin.
To authenticate with the Kestra API, you need to provide an API token with the necessary permissions. You can generate a token from the UI by going to the Service Accounts tab under the IAM page, creating a new service account and generating a new token from the API Tokens section. We recommend adding that token as a secret in the system namespace. Here, we've named the secret API_TOKEN.
We've set up retries via pluginDefaults to handle any network issues or temporary failures.
Make sure to adjust the host and newTenant variables in the flow configuration to match your environment and requirements.
