Hi Melanie,

Creating a new page is a good idea, but I think we need to do some other
documentation/overviews first, to avoid confusion around our multiple
containers approaches (single container vs pulp-operator.) Also to decide
on which easy approach to promote as the best way to *try* pulp.

I agree with you on moving the repo, but note that a rename is planned, so
they should probably be done at the same time.


We started work on pulp-operator (a Kubernetes operator) as a sophisticated
set of containers for running Pulp months ago. Once production ready, it
will be easy to run for users *if* they already have a full Kubernetes
container infrastructure; operators are supposed to provide an app-store
like experience where the # of containers is abstracted away.

Later on, we discovered that we could provide a quick & easy way for users
to try Pulp 3 by writing an install script around pulp-operator and K3s
(lightweight kubernetes.) It's almost like an alternate mode of
pulp-operator. It is called "pulp-insta-demo.sh", and it is listed on our
home page as "Quickly Try Pulp": https://pulpproject.org/ . All users have
to do is run it on a standard Linux desktop. laptop or server, without any
options or config, and it usually works.

Because many users need to use a single host to run a single container,
with directories for storage, etc, we later started work on the single

I've been meaning to write a post about pulp-operator, introducing it, but
didn't have time.

Then Dennis and I intended to add a comparison to pulp-operator in his
post, but it fell through the cracks in this hectic (global crisis) month.

I did however write a related-tooling page afterwards, that minimally
introduces pulp-operator, and compares pulp-operator to the single
https://github.com/pulp/pulpproject.org/pull/253 (PR I just submitted to
add pulp-insta-demo.sh)

*What I propose we do*:

I think we should write a post introducing pulp-operator, including
pulp-insta-demo.sh .

Then write another post comparing the 2 container solutions
(pulp-operator/pulp-insta-demo vs the single container) in greater detail
than the "related tooling" page does.
Perhaps it should be a page (rather than blog post) comparing
pulp_installer as well. An overview of all the ways to install Pulp 3.
(To make matters more complicated, we also have manual install
instructions, which is a manual way of deploying Pulp how pulp_installer

Then we should decide which approach (single container vs pulp-insta-demo
mod of pulp-operator) to list as the recommended way to try Pulp 3. (Again,
currently the home page has pulp-insta-demo.)

Then we should write a page about the easiest way to try Pulp 3.

Again, these are only my thoughts, and what I've been planning to do. I am
very glad you joined our team; because having multiple installers/packages
is a situation that I really feel we need community manager guidance on.
