How to completely uninstall / remove a plugin

Supporto Installazione
1

I only rebuild a few times per year. I am currently running into an issue with a plugin I do not want.

When I include the plugin repository in my app.yml file I can bootstrap but run into blank screens with the following errors:

When I comment out the plugin repository in app.yml I fail to bootstrap.

So my question is, how can I fully remove the plugin(s) and all of their remnants from my install as if it were never there in the first place?

Can you share the error in bootstrap when doing a rebuild without the plugin?

Here is the error when I try to bootstrap without the plugin.

FAILED
--------------------
Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #     <Process::Status: pid 22379 exit 1>
Location of failure: /pups/lib/pups/exec_command.rb:108:in `spawn'
exec failed with the params {"cd"=>"$home", "hook"=>"bundle_exec", "cmd"=>["su discourse -c 'bundle install --   deployment --verbose --without test --without development'", "su discourse -c 'bundle exec rake db:migrate'", "su  discourse -c 'bundle exec rake assets:precompile'"]}`

And then scrolled up I get this:

I, [2017-01-01T23:52:03.038385 #15]  INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate'
URGENT: type Failed to initialize site default
rake aborted!
ArgumentError: type

Handy with most things but I don’t know where to start with this because I bootstrap fine with the plugin.

Looks like df-core is the plugin at fault. Isn’t that one of the Discouse PRO plugins? It’s been a while since I looked at the code on those but if memory serves they contained db migrations. Not sure if that’s good or bad at the moment.

Is it possible that by removing the plugin (and thus removing the migrations) it’s throwing an error?

nobody knows how to just remove a plugin??

To remove a plugin, simply remove the - git clone https://github.com/... line from your app.yml file and rebuild your site via ./launcher rebuild app.

Would that method remove the entries the plugin would have created in the database, like tables or records?

Or when you uninstall a plugin garbage in the database would be left after it?

I did this method multiple times, the Fingerprint plugin will not uninstall even though it is not in my app.yml.

How to delete this anyway?

11

Did you rebuild after you edited your app.yml?

Did you clear you local cache?

12

Yes, I’ve had several rebuilds and changes since. I cleared my cache.

13

And you saved after you changed your app.yml :man_shrugging:

14

Ofcourse, otherwise plugins I installed after would not install, but they are :grinning:

In a support forum nothing is obvious :scream:

Per chi amministra Discourse solo occasionalmente, per i principianti o, in generale, per risparmiare tempo, è molto utile essere il più specifici possibile.

In questo caso specifico, dove si trova esattamente il file app.yml? Non ne vedo uno in /var/discourse, ma ne vedo uno chiamato app-sparkpost.yml. Forse è il file che ho creato circa 5 anni fa quando ho distribuito l’istanza; non ne sono sicuro. È questo il percorso corretto? Come fa Discourse a sapere di dover leggere questo file se non c’è nessun app.yml in /var/discourse?

Non mi aspetterei di trovare file YAML in /var/discourse stesso, no. Il percorso corretto sarebbe /var/discourse/containers. Credo che Discourse legga tutti i file nella directory containers, ma un ingegnere sarà meglio attrezzato per rispondere a questa domanda rispetto a me. Non penso che il nome abbia davvero importanza.

Credo che app.yml si trovi in /var/discourse/containers/app.yml. Dovrai modificare quel file ed eliminare tutti i riferimenti al plugin. Dovresti essere in grado di trovare qualcosa di simile al seguente esempio nel file:

## I plugin vanno qui
## vedi https://meta.discourse.org/t/19157 per i dettagli
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-jwt.git
          - git clone https://github.com/zh99998/discourse-cross-origin.git

Ogni riga git clone qui si riferisce a un plugin installato nell’istanza di Discourse. Dopo aver modificato il file, dovrai ricostruire la tua applicazione Discourse. Dalla cartella /var/discourse puoi eseguire ./launcher rebuild app per ricostruire la tua applicazione Discourse.
