Run Linux on IBM Z Docker Containers Inside z/OS

Whilst this isn't upon which I'm currently working, it's definitely of interest and relevance: -

 Everybody knows that Linux* runs on IBM Z*, but what if you could build a hybrid workload consisting of native z/OS software and Linux on Z software, both running in the same z/OS* image?

Starting from z/OS V2R4, with an exciting new feature named IBM z/OS Container Extensions (zCX), you have a new way to run Linux on IBM Z Docker containers in direct support of z/OS workloads on the same z/OS system. It builds much more flexibility into operations on IBM Z by modernizing and extending z/OS applications.

“With zCX, customers will be able to access the most recent development tools and processes available in Linux on the Z ecosystem, giving developers the flexibility to build new, cloud-native containerized apps and deploy them on z/OS without requiring Linux or a Linux partition,” says Ross Mauri, general manager for IBM (ibm.co/2W04VWW).

See the zCX website (ibm.co/2JaDzWe) if you are interested in more details.

Note to self - use kubectl to query images in a pod or deployment

In both cases, we use JSON ... For a deployment, we can do this: - kubectl get deployment foobar --namespace snafu --output jsonpath="{...
