Nothing displayed on launcher rebuild

I’m trying to follow the guide for adding support for MySQL gem to the app container via the tutorial How to use the bbpress import script - or any other import script with mysql dependency

However, when I run the following, it just halts.

> ./launcher stop app
> ./launcher rebuild import

Until I kill the process with CTRL+C

Note: I have waited more than couple of hours for it to show any response but nothing

And when I inspect the docker containers, it shows a new (corrupt) stopped container

I’m not sure what am I doing wrong, which leads to this behavior.

My containers/import.yml file contents (stripped out the untocuhed part):

The server is hosted on DO and when I restart the docker service, it returns back the original running app container.

P.S: ./launcher rebuild app works fine though.

Maybe do a ./launcher stop app; before trying to build import?



Yes, obviously I’m running the rebuild following the stop sub command. Let me edit my question.

OK I figured. After I stopped the container

> ./launcher stop app

I also removed the container docker rm app and tried to rebuild thereafter, and it proceeded further.

Now, when I get to the point where it’s using the mysql-dep template, the following error is thrown.

You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.

If this is a development machine, remove the /var/www/discourse/Gemfile freeze 
by running `bundle config unset deployment`.

The dependencies in your gemfile changed

You have added to the Gemfile:

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.

Does anyone know anything about this error please?


I’m having similar issues. This seems the same as Failed to bootstrap using import template.

And I meant not to try to upgrade that container because I’d seen this, but I tried anyway because of another strange error. . .

EDIT: I added the

su discourse -c 'bundle config unset deployment'

To the template before the

 su discourse -c 'bundle install --no-deployment --path vendor/bundle --jobs 4 --without "test development"'

line and it’s working. (But, alas, didn’t solve my unrelated problem).


I literally just used this template last week and had no issues with it. Quite odd but it’s worth a look next week. I’ll add it to my list.


Me too! But I guess something for upgraded?


In addition to the comment, I also had to skip launcher prerequisites

> ./launcher rebuild import --skip-prereqs

and following the suggestion of @pfaffman

the image built successfully. :white_check_mark:


Looks like this is resolved here – @pfaffman @rahilqf can you confirm?


Looks like it. Thanks very much!

Now if there were only a template that would add php-serialize. . .
