Drain and Replace EKS Worker Nodes
Unliked managed node groups, EKS worker node groups have to be recycled outside EKS after updating the AMI reference. I recently migrated all of my hosted sites from ECS to EKS and am using terragrunt/terraform for all infrastructure as code. I then upgraded the AMI that I used for the worker node groups and had […]

AWS LoadBalancer SSL Redirect with Bitnami Helm Chart(s)

Why doesn’t Bitnami support adding an SSL redirect for AWS LoadBalancing in their helm charts?

AWS Access Keys in S3 Bucket Policies
I’ve seen what appeared to be AWS Access Keys in S3 bucket policies as an AWS principal in the past. I could never figure out why this was happening and nobody appeared to be adding them. The Access Key never showed up as a valid user Access Key in a search of IAM objects either. […]

Adding Global Environment Variables to Jenkins via puppet…

I always forget to remove this parameter. A good way that I have […]

Throttling Requests with the Ruby aws-sdk
A common problem of late is throttling requests when using the ruby aws-sdk gem to access AWS services. Handling these exceptions is fairly trivial with a while loop like the following: retry_count = 0 retry_success = 0 while retry_success == 0 retry_success = 1 begin # # enter code to interact with AWS here # […]

Multipart uploads to s3 using aws-sdk v2 for ruby…
The Ruby guys over at AWS have done a great job at explaining file uploads to S3 but they left out how to perform multipart uploads citing reservation over “advanced use cases“. Prerequisites: identify an S3 bucket to upload a file to — use an existing bucket or create a new one create or identify […]
