I have a CloudFormation stack that includes EC2 instances, IAM roles and an autoscaling group. This is a transient stack that performs a load test in a target ALB. Once the test completes (it is limited in time), results are sent and this stack should be removed.

Right now I create the stack from my computer using my credentials, although my final intention is to have this automated in a CodePipeline step.

I was trying to make the stack to call for his own deletion using the CLI:

I have been following this guide to create a Kubernetes cluster via CloudFormation, but the NodeGroup never joins the cluster, and I never get an error or explanation about why is not joining.

I can see the autoscaling group and the EC2 machines are created, but EKS reports that there is not node groups.

If I create a new node group manually through the web admin tool, it works, but it assigns different security groups. It has a launch template instead of a launch configuration.

Same AMI, same IAM role, same machine type...

I am very new in both CloudFormation and EKS, and I don't know how to proceed now to find out what the problem is.

Here is the template:

Bellow is the Node status of my Elasticsearch cluster(please follow the node.role column,

I'm building an app with two kind of nodes (front and back) on akka 2.5.1, I'm using akka sharding for load and data distribution across the back nodes. The front node uses a shard proxy to send messages to the back. Shards initialisation is as follow:

I am trying to write a FHIR/RDF model to a Turtle (TTL) output file and validate it against a reference schema using ShEx. I have created a Jena model and am using the RDFDataMgr class to write it out. The problem is that the resulting output does not look like the Turtle output used in the FHIR examples. Specifically, it adds angle brackets where there are none; it does not use the subject-"a"-type syntax that is idiomatic Turtle; most importantly, it fails to validate using the FHIR validation tool. I have read through the Jena docs and not found any more granular controls over the output than what I am using, so I am hoping someone with more depth in the area can point out what I should be doing to get the expected output. It's a bit of long post; thanks for reading.
