What is Filter Node?
The Filter node selectively retains a subset of AWS resources from a large set of particular AWS service as per the conditions and nested conditions defined in this node’s parameter window or according to the parameters derived from the previous Resource node.
Working with Filter Nodes
To define a Filter node in a Workflow, follow the steps below:
- Go to the workflow editor, and start a new workflow or select an existing template
- If you start a new workflow:
- Click on the plus symbol
- Select 'Resource' from the options below
- Click on 'Edit' to access the parameters input window
- If you pick an existing template:
- click on the 'Edit' option existing Filter node to access the parameters input window.
Example: If you need to take action on IAM users whose Access Keys age are greater than 90 days – and want to delete these old IAM roles, you need to define conditions in the Filter node as shown below.
- Use And or Or to define multiple conditions and sub-conditions to refine your workflow as per your needs.
- Click on 'Save' after you set the parameters according to your requirement.
For your convenience, we have pre-configured filters.
Types of Filters
- Param: Helps filter resources by their attributes or their Add-ons attributes.
- Tags: Helps filter resources by their tags.
- Security Group: Helps filter certain resources based on the properties of Security Groups associated with those resources or directly on the Security Groups themselves. Note that it is applicable only to EC2 SGs, Cluster SGs, mount target SGs, Cache SGs, DB SGs and Stale SGs.
- Network ACLs: Helps filter certain resources based on the properties of NACL Rules associated with those resources or directly on NACL. Note that it is applicable to subnets that have associated NACL Rules.
- Function: Helps selectively filter resources using custom Java scripts, when none of the other Filters work.
- Time/Date: Ideal for filtering resources based on date value, such as 'Launch Time'.
For your convenience, we have populated few usage examples showcasing how to apply filters for some common use cases. Check here.
