deploy current branch error or am I missing something?

[stefanosc]

I just had a look at the latest commit https://github.com/mattpolito/paratrooper/commit/341f9f213de2b1b6a71d807e00ccbc3218d1fabf

And followed the various conversations around this, including pull https://github.com/mattpolito/paratrooper/pull/53

As part of my deploy task I tried various options:

Paratrooper::Deploy.new("myapp-staging", tag: 'staging', branch: "HEAD")
Paratrooper::Deploy.new("myapp-staging", tag: 'staging', branch: :head)

as described in lib/paratrooper/deploy.rb

And I get this:

Fetching repository, done.
error: src refspec refs/heads/HEAD does not match any.
error: failed to push some refs to '[email protected]:myapp-staging.git'

If I don't pass any :branch value to the Deploy instance then it only deploys the master branch.

is there a way to simply deploy the current branch to staging without having to manually edit the rake task with the branch name?

Thank you very much

[mattpolito]

What scenario are you trying to make happen with this declaration? Paratrooper::Deploy.new("myapp-staging", tag: 'staging', branch: :head)

[stefanosc]

@mattpolito I would like to deploy the branch from which I execute the rake deploy command. When reading the comments:

# :branch                - String name to be used as a git reference
#                          point for deploying from specific branch
#                          point for deploying from specific branch.
#                          Use :head to deploy from current branch

I understand that I need to set :branch to :head but it throws an error as I wrote. Am I missing something?

This is a brand new feature that came in via a PR. I have yet to use it. Let me look into it and see if I can help. Sorry that it's not working out for you.

[stefanosc]

@mattpolito thank you. I did notice the commit is just from a few days ago! Meanwhile I found a solution which seems to be how the script should work:

branch = `git rev-parse --abbrev-ref HEAD`
deployment = Paratrooper::Deploy.new("myapp-staging", tag: 'staging', branch: branch )

Let me know if this helps and if you see anything else. Thanks

[mattpolito]

@stefanosc did you have an issue when using the symbolized :head branch name? I definitely see an issue when "HEAD" is used but looks like it would have worked with :head.

@mattpolito same issue

@mattpolito Just a quick update: I was able to push / deploy any current branch as per my https://github.com/mattpolito/paratrooper/issues/69#issuecomment-50878785

Then I tried again today and ran into another issue:

❯❯❯ rake deploy:staging                                                                          ✭ ✱

I am not sure what happened but nothing works today.

then I noticed at https://devcenter.heroku.com/articles/git

git push heroku yourbranch:master

For the time being I pushed without paratrooper. It would be handy to be able to easily push local branches to staging. Let me know if I can help in some way.

[mattpolito]

@stefanosc This one has really been messing with me. Under the current master branch I cannot reproduce what you are seeing. Are you still having issues?

[stefanosc]

@mattpolito thank you for looking into this. The only issue happens when deploying from a branch other than master. So, yes, you would not be able to reproduce the above if you try to deploy from your master branch. In case of any misunderstanding: I am trying to find a way to deploy "current branch" (non master branch). I am definitely still having issues with this and I am only able to deploy master branch, any attempt to deploy any other branch fails.

Let me know if there is anything I can do. Thank you

[debreczeni]

I do have this working on current master (0360076) but it works very unintuitively:

Paratrooper::Deploy.new app_name,
  ...other args...
  tag: environment,                    # production, staging, canary, etc...
  branch: ref == 'HEAD' ? :head : nil, # explicit HEAD or non-canonical git ref which can be either a tag or a branch name
  match_tag: ref                       # explicit HEAD or non-canonical git ref which can be either a tag or a branch name

This way I can specify a tag name environment for each of my environments, and a git ref ref for what I want to deploy.

[stefanosc]

@debreczeni thank you for posting your solution. I am not sure I can follow. What is ref? And how does it work if you set the match_tag to nil if you are not in HEAD branch?

I had created the following staging rake task which worked initial but I can figure out what's wrong with it now:

namespace :deploy do
  desc 'Deploy app in staging environment'
  task :staging do
    branch = `git rev-parse --abbrev-ref HEAD`
    deployment = Paratrooper::Deploy.new("loveflix-staging", tag: 'staging', branch: branch )

    deployment.deploy
  end
...
end

Thanks!
