From my experience as a writer for https://opensource.com, I would say that the term "container" is as potent (if not more, these days) as "Docker". It didn't used to be that way, but if I post something about containers now, I don't see an appreciable difference in engagement between what we used to get for articles about Docker specifically.

I don't have numerical data to support this, and it could be an anomaly with just my audience, so take it with a grain of salt.

I do think mentioning both docker and podman in the course title could be good as a catch-all, but I guess I'm suggesting you ride on the term "container", and mention podman, dockerfile, buildah, and all those predictable SEO terms in the course description.

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

  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.

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.
