I want to make modification to the appearance of [discourse](https://github.com/discourse/discourse/) by plugin.
Due to the plugin architecture I have to fork repos.
First I changed repo in [discourse\_docker](https://github.com/sevenmaxis/discourse_docker/commit/793b33b36fb627b42946c79f2ecb89a4f64e5900) at my forked [discourse\_docker](https://github.com/sevenmaxis/discourse_docker)
Then I forked [discourse](https://github.com/sevenmaxis/discourse) itself, add some [change](https://github.com/sevenmaxis/discourse/commit/46c7f6ece856c12a67dd06747731d9b3f1c56ca1) to test.
Went to my in [instance](http://37.48.87.4/), checked Dockerfile - it had link to my repo, installed all by instruction, build an app, enter that app and check
`git remote show origin` - it didn’t change:
```
Fetch URL: https://github.com/discourse/discourse.git
```
I’ve tried to remove images and rebuild them, same result
What am I missing here?
Maybe it doesn’t build image from `image/discourse/Dockerfile` and downloads from `DockerHub` instead?

Forced to build the docker image locally, retagged as `discourse/discourse` and launched.
Now git repo shows the right link, but didn’t fetch my last commit from repo, looks like it cached somewhere.
I can force to fetch all commits but it’s not a solution.
Any ideas what might be a problem?

You have to change the repo (as well as any other change you would like to make) using app.yml
If you have issues doing this, let me know and I will post the commands.

app.yml has only repo’s to plugins, isn’t it?
Now I’m sure it doesn’t build image from Dockerfile, this from terminal:
```
Unable to find image 'discourse/discourse:1.3.5' locally │-bash: ./launcher: No such file or directory
1.3.5: Pulling from discourse/discourse
...
```
How to build the local image?

You need to add a command in `app.yml` to change the `origin` remote to point to your fork, otherwise the base image will still be using the official Discourse repo. You can build your own base image, too, but that’s a lot more effort to keep maintained, and will likely cause Confusion and Delay in the future. So, just add this to your `app.yml`:
```
run:
- exec:
cd: /var/www/discourse
cmd:
- sudo -u discourse git remote set-url origin https://git.example.com/discourse.git
- sudo -u discourse git fetch origin
- sudo -u discourse git checkout origin/master
```
You can also do various other forms of the above git commands, to get the code you want checked out, checked out.

Thanks Matt, that’s what I needed
But problem still remains. It has the right repo link, the repo itself cloned correctly but it has no affect, my view didn’t change. Maybe I should put this code like this:
```
hooks:
before_code:
- exec:
cd: /var/www/discourse
cmd:
- sudo -u discourse git remote set-url origin https://github.com/sevenmaxis/discourse
- sudo -u discourse git fetch origin
- sudo -u discourse git checkout origin/master
```

So I added to `before_code` hook.
It fails on command `git checkout origin/master` with message:
```
FAILED

**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one
```
I’m sure that it fails on `git checkout origin/master`, I’ve incrementally added `remote set-url`, `fetch origin` and `checkout origin/master`, it fails exactly on last command. But I can’t see any clue in the error message.

In the past, I’ve done it by editing `app.yml` like this:
```yml
hooks:
after_code:
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/docker_manager.git
- git clone https://github.com/scossar/localized-categories
- git clone https://github.com/scossar/dictionary-card-onebox
- exec:
cd: $home
cmd:
# changes start here
- git remote remove origin
- git config --remove-section branch.master
- git config --remove-section branch.tests-passed
- git remote add origin https://github.com/scossar/discourse-dev
- git fetch
- git remote set-branches --add origin anonymous-locale
- git branch -u origin/anonymous-locale
- git reset --hard origin/anonymous-locale
```
If you are only needing a plugin outlet added to Discourse you could try making a pull request to Discourse for the addition.

`git reset --hard` works, but `git checkout origin/master` didn’t work, that’s strange. I was wrong about `before_code`, it should be in `after_code` section
