As you may notice the parameter:
is not supported in Fargate but for many of us this is a gruesome headache because we use hosts groups for many purposes like assigning membership to MZ's among others.
But the following guide is a step by step solution to resolve this using a workaround.
ENV DT_CUSTOM_PROP "Host_Group=AWS-EKS-FARGATE-SWITCH"
Please pay attention to the options on the numbers 1 to 8.
My main inspiration for writing this PRO TIP is to create a guide based on ideas I saw in another post. This is the guide I wish I had found in the first place for this topic. Using that solution as a base I had to sort and test ideas and adapt to the new interface, I want to thank to @abraham_villega original answer on that post. and to my fellow Jason @ct_27 for contacting me, you were the trigger to start writing.
