I agree with most of Dmitry's statements and it seems in MVP we need plugin management UI where we can enable installed plugins. It should be a separate page.

You can also disable and uninstall plugins using that page (if there is no environments with the plugin enabled).<br><br></div>The main reason why I'm against Evgeniy's 2nd approach (explicitly enabling plugins in the wizard) is that we need to add a step where we choose the plugins. This step should be added right after choice of environment name and release, because options on the next steps and even steps could be added from plugins. And this is complete disaster for UX. Imagine a new user which uses Fuel for the first time and has to decide which plugins he will use right after giving a name to an environment.<br><br></div>So I think if we implement plugin management page and make user explicitly and globally enable installed plugins there we can implement Evgeniy's 2nd approach, but in a slightly different way. I think we need to use all enabled plugins for new environments by default and let user to uncheck some of them, so they won't be used for that particular environment. I think the checkboxes should be right on the first pane under release selectbox (it makes sense because different releases could have different plugins available). These checkboxes should be hidden by default and only appear after user clicks a button named like "customize used plugins". I think we should use the word "use" here instead of "enable" as we "enable" plugins on the plugin management page.<br><br></div>The plugin management page and explicit enabling of plugins are also required for plugins with an UI part as we need to preload it when UI loads and not when the wizard opens as the plugin can contain mixins for the wizard.<br><br></div>What do you think?<br></div><div><div><div class="gmail_extra"><br><div class="gmail_quote">2014-10-09 11:04 GMT+07:00 Dmitry Borodaenko <span dir="ltr"><<a href="mailto:dborodaenko@mirantis.com" target="_blank">dborodaenko@mirantis.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I don't like how this discussion is framed. The initial premise that we have<br>
only two controversial options to choose from is lazy. If there is no<br>
consensus, we should look for more options, not for a popular vote.<br>
<br>
Secondly, current level of UX is not negotiable. You can't take something that<br>
we already have and that works (and current Fuel UI is the best out there by a<br>
wide margin), and make it worse just to add a new feature. Even something as<br>
important as plugins must be an incremental improvement.<br>
<br>
With that premise, lets decompose the problem.<br>
<br>
1. There are two levels of settings related to any plugin: a) first you have to<br>
enable enable the plugin itself; b) when the plugin is enabled, it may expose<br>
additional settings.<br>
<br>
- How can it be acceptable to have all plugins always enabled in all<br>
environments? Do you really trust all plugin writers to carefully check for<br>
plugin-specific options and ensure there is zero impact on an environment if<br>
none of its options are enabled?<br>
<br>
- If all your plugins are enabled everywhere, you can't uninstall any of them<br>
because all environments you deployed would become unmanageable.<br>
<br>
- If you ignore uninstallation, soon you will be stuck with plugins that cannot<br>
be made removable even when Fuel itself begins to support it.<br>
<br>
- To break away from unremovable plugins, you're likely going to have to break<br>
backwards compatibility (unless you already have a forward-compatible design<br>
that allows for removable plugins in the future, but then you wouldn't have<br>
to exclude removing plugins from MVP).<br>
<br>
- And if a Fuel upgrade ever requires uninstalling a plugin due to<br>
irreconcilable incompatibility, and they're enabled in all of your<br>
environments, you're stuck unable to upgrade.<br>
<br>
So, lets not enable any plugins by default. And if we can come up with a way to<br>
make them removable (when they're not enabled in any deployed environments), we<br>
should at least leave room for that in the design.<br>
<br>
2. Either level of plugin settings (enable or configure) may be exposed in<br>
setup wizard, settings page, or both.<br>
<br>
- Yes, additional plugin settings also may show up in the wizard (e.g. vCenter<br>
credentials).<br>
<br>
- Yes, we should maintain the settings page as the SSoT, and that means<br>
reflecting as many of setup wizard options in it as possible.<br>
<br>
- Yes, for some options (like choice of operating system or network topology),<br>
our settings page is not dynamic enough to allow user to go back and revert<br>
them without recreating the environment.<br>
<br>
- No, plugin writer shouldn't have to explicitly describe a checkbox to enable<br>
their plugin. They only should provide name and description of the plugin.<br>
Plugin engine should be able to produce a catalogue of installed plugins, and<br>
UI should generate enable checkboxes from that catalogue.<br>
<br>
- If a plugin doesn't affect any available environment configuration options<br>
outside of the settings tab (i.e. setup wizard, network settings, node roles,<br>
disk & nic configuration), there's no reason to limit it to setup wizard, the<br>
"enable" checkbox and whatever other options it has should all be present in<br>
the settings page.<br>
<br>
- Do we have any plugins in 6.0 that have to be present in setup wizard because<br>
they affect UI outside of settings page? I'm not aware of any.<br>
<br>
If so, lets start by representing all plugin settings in the settings page. But<br>
leave the room in the metadata to force some or all of plugin's settings to<br>
show up in the setup wizard (or even to present plugin configuration options<br>
differently in the wizard than in the settings).<br>
<br>
Just my $2,<br>
