[DISCLAIMER: i hope this question isn't terribly inappropriate for this list, as it's about my wondering how to write/market an intro "docker" course but using podman and buildah instead, and i'm open to suggestions.] i'm a long-time trainer, teaching both my own courses and for others (red hat, for instance). a couple of my course reps have recently asked me if i have a docker course as some of their clients have been asking for one, and i'm torn as i don't quite know how to answer that. when i ask for more details as to what the client is really after, i generally get little more than, "they just want introductory docker." *sigh*. so here's my dilemma. a 1-day intro docker course is pretty straightforward, stuff like: * what's a container (as opposed to a VM)? * running an image * using Dockerfiles * volumes that sort of thing ... covering the above in reasonable detail can easily fill a day. but me being a red hat/fedora person, i'd much rather teach using podman and buildah, but then it's not really a "docker" course, is it? (one of the questions i ask my reps is whether the client really and truly wants "docker", or whether they want general container training? asking that question never ends well. :-P even when something is superior and cutting-edge technology, that may not be the selling point -- managers understand the word "docker" and, by god, that's what they want their engineers to get. one argument for podman is that, with the release of centos 8 back in sept of 2019, i can at least point at an enterprise-level OS that supports podman out of the box, which will certainly increase the comfort level, but it's still no guarantee. so, thoughts? for a 1-day intro course, the differences between docker and podman are probably negligible -- for advanced courses, yes, the differences will become more pronounced, but intro-level stuff should be safe. perhaps a proper title would be "introductory container technology using docker and podman", or something suitably all-encompassing. for people who do this kind of training, what do *you* do these days? the course itself is easy enough to write -- i'm just trying to figure out how to title and position this. rday p.s. if there are folks on this list who already do this sort of thing and have courseware and are willing to license it, i could be talked into that as well, so drop me a note. _______________________________________________ Podman mailing list -- podman(a)lists.podman.io To unsubscribe send an email to podman-leave(a)lists.podman.io
