-----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Kirk Wolf Sent: Friday, May 17, 2019 1:53 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: z/OS Container Extensions Docker is a virtualization technology which is different from a "virtual machine". See an overview like: https://www.infoworld.com/article/3204171/what-is-docker-docker-containers-explained.html The zCX engine/host operating may be based on Ubuntu Linux; it isn't technically correct to say the the "Linux *kernel* is Ubuntu". Also, it doesn't matter too much that the Docker engine/host operating system is a particular Linux distribution. Docker images derived from different distributions can run in it. To confuse things, the zCX engine/host linux operating system runs inside a z/OS address space using virtual machine technology. I'm sure I helped not at all :-) On Thu, May 16, 2019 at 3:31 PM David Purdy < 000000ac4b1d56b3-dmarc-requ...@listserv.ua.edu> wrote: > We learned at Share Phoenix that the Linux kernel is Ubuntu. > > David > > On Thursday, May 16, 2019 Jousma, David <IBM-MAIN@LISTSERV.UA.EDU> wrote: > I've seen bits and pieces....I believe It's a blackbox secure setup. > No on-site Linux administration aside from application admin or > maintenance required, no ROOT access.
