Per Enqueue Zero, Nsenter is a utility enters the namespaces of one or more other processes and then executes the specified program. In other words, we jump to the inner side of the namespace. Search for the namespace, by searching for S+, and then using the PID to target the namespace, and run the local tools in the namespace. This is very helpful where the docker container does not contain the necessary tools by default.

Never accept the defaults: Lessons Learned using OpenJ9 in a Container

Never accept the defaults: Lessons Learned using OpenJ9 in a Container Eclipse OpenJ9 is an efficient virtual machine with a small-dynamic footprint that is used for many cloud applications.  Many applications use the OpenJ9 to run their applications, such as the Apache OpenWhisk, IBM FHIR Server and Open Liberty. I learned a few things about running Java applications with the OpenJ9 VM in Docker: Eclipse OpenJ9 knows about modern applications Tweak Your Settings Review your Settings 1.   Eclipse OpenJ9 knows about modern applications The Eclipse OpenJ9 team smartly realized many Java applications are in a container or namespace or virtual…

Bulk Data Configurations for IBM FHIR Server’s Storage Providers

As of IBM FHIR Server 4.10.2… A colleague of mine is entering into the depths of the IBM FHIR Server’s Bulk Data feature. Each tenant in the IBM FHIR Server may specify multiple storageProviders.

Note, type http is only applicable to $import operations. Export is only supported with s3, azure-blob and file. File Storage Provider Configuration…

GitHub Actions: Concurrency Control

My team uses GitHub Actions 18 in total jobs across about 12 workflows. When we get multiple pull requests we end up driving contention on the workflows and resources we use. I ran across concurrency control for the workflows. To take advantage of concurrency control add this snippet to the bottom of your pull request workflow: When you stack the commits you end up with this warning, and the prior job is stopped:

Using Docker and Kafka with IBM FHIR Server Audit for Testing

Thie attached GIST is a package of Kubernetes yaml files and Java code to test locally with Docker/Kubernetes with the IBM FHIR Server. You’ll want to kubectl apply -f <filename> for each of the files. Then apply the fhir-server-config-snippet.json to your fhir-server-config.json And run kubectl config use-context docker-desktopkubectl -n fhir-cicd-ns port-forward kafka-0 9092 Thanks to https://github.com/d1egoaz/minikube-kafka-cluster for the inspiration.
