Does Heroku supports context building like Openshift supports? Like, i have this repository but i want to build only inside a specific folder in github webhook.
I coud not find anything in interface and for CLI i just could find resources using the heroku-git. It needs to be IN THE GITHUB WEBHOOK, is there anyway to do that? The method for commit to a heroku origin is not what i'm looking for.

Very inexperienced user here...please be patient!
I inherited maintenance of Heroku app from someone no longer with the company. Having to re-deploy an app update is probably a once-a-year event, and here we are.
The instructions I have include building a standalone jar file containing my app and then deploying it to Heroku. Specifically the procedure for this is to use the Heroku CLI with the following command:
heroku deploy:jar webapp.jar -a my-app
Easy enough. Except he had his own instance of the Heroku CLI, and when I went to download my own copy, it appears that the deploy command no longer exists! Is this the case? Is this a deprecated command? Do I need to go through the process of figuring out how to set up a git repository to deploy this? (We are in fact using git to manage the source for this app, but it's behind our company firewall, so I'm not sure how practical/difficult it will be to set this up for Heroku). I just want to make sure I'm not missing something simple before investing a significant amount of time re-inventing the deployment process. Thanks.
The most popular mechanism is indeed to push the code from git to Heroku, providing the necessary files (i.e. profcile) to deploy the runtime.
An alternative is to create a Docker image and push it to the Heroku Registry (which in your case would require more reworking).
Refer to Deploy with Git, the firewall should not be a problem as Heroku will not access your code, but you will need to perform the push (git push heroku master)
I have to answer my own question because I was able to find the solution.
It turns out there is a plugin available for the heroku CLI that provides the deploy command. Running heroku plugins:install java will install the plugin that provides the deploy command in the heroku CLI.
See https://devcenter.heroku.com/articles/deploying-executable-jar-files for more information.
Background: I have a project deployed to heroku. The heroku app is connected with github so I can press the "deploy" button from heroku's web api to manually deploy a branch on github to heroku.
What I'm trying to do is build a slack bot that will let me accomplish that via a slack command. Ideally, there'd be some function on heroku's platform api like .deploy('my_app', 'some_branch_on_github), but I can't seem to find it.
The platform api's build feature is close. That function lets you provide the public url of a tarball that heroku will then deploy. However, my github repo isn't public, so that doesn't work. A private repo shouldn't be a problem, though, since heroku's already connected to my github repo.
TLDR: How can I programmatically tell Heroku to deploy my app from a private github it's connected to?
I got a response from Heroku's support team asking pretty much the same question. Their answer was that what I'm trying to do is not possible, but will be at some point (although not in the next few months, anyway).
They suggested that I could just use the undocumented web api used by heroku's own web console (a POST to an endpoint on kolkrabbi.heroku.com). They did warn that, as a private api, that's likely to change without warning.
As of April 2020, Heroku has integrated GitHub natively without recourse to any janky undocumented Icelandic endpoints.
When configured, Heroku can automatically build and release (if the build is successful) pushes to the specified GitHub repo.
Enabling GitHub integration
You can configure GitHub integration in the Deploy tab of apps in
the Heroku Dashboard.
To configure GitHub integration, you have to authenticate with GitHub.
You only have to do this once per Heroku account.
GitHub repo admin access is required for you to configure automatic
GitHub deploys. This is because Heroku has to register a service hook on
the GitHub repo, and this action requires admin access. For GitHub
organizations, your GitHub account will also need to be a member of the
organization and not an outside collaborator.
If your repo is in a GitHub organization that has third-party
application restrictions
enabled,
an organization admin needs to approve Heroku for use with the
organization. More details are available on
GitHub.
After you link your Heroku app to a GitHub repo, you can selectively
deploy from branches or configure auto-deploys.
Manual deploys
With manual deploys, you can create an immediate deployment of any
branch from the GitHub repo that’s connected to your app. Use manual
deploys if you want to control when changes are deployed to Heroku.
You can also use manual deploys to temporarily deploy a branch other
than the one that’s configured for automatic deployment. For example,
you might have a development app synced to the development GitHub
branch, but you temporarily want to test a feature branch. Simply
trigger a manual deploy of the feature branch to test it on the Heroku
app. Note that release of the feature branch is overwritten on the next
successful GitHub push to the development branch.
Automatic deploys
When you enable automatic deploys for a GitHub branch, Heroku builds and
deploys all pushes to that branch. If, for example, you have a
development app on Heroku, you can configure pushes to your GitHub
development branch to be automatically built and deployed to that app.
If you’ve configured your GitHub repo to use automated Continuous
Integration (with Travis CI, for example), you can check the “Wait for
CI to pass before deploy” checkbox. When enabled, Heroku will only
auto-deploy after all the commit statuses of the relevant commit show
success.
This commit won’t auto-deploy because one of the checks shows a
pending status:
This commit will auto-deploy because all of the checks show a status of
success:
Review apps
With review apps enabled for a Heroku app, Heroku will create temporary
test apps for each pull request that’s opened on the GitHub repo that’s
connected to the parent app. Review apps are great if you’re using
GitHub Flow to propose,
discuss, and merge changes to your code base. Because pull request
branches are deployed to new apps on Heroku, it’s very simple for you
and your collaborators to test and debug code branches. You can also run
automated integration tests on the Heroku app representing a GitHub
branch.
See the Review apps
article
for details.
Heroku CI
Once you’ve connected your GitHub repo to your Pipeline, you can turn on
Heroku CI, our
visual, low-configuration test runner that integrates easily with Heroku
Pipelines (and so complements Review apps, existing Heroku apps, and our
GitHub integrations). Any Heroku Pipeline is already Heroku CI ready –
just turn it on in the Pipeline’s Settings tab.
Links to diffs
For apps that are linked to GitHub repos, releases in the Dashboard
Activity tab will include a “View Diff” link. Following the link
will take you to the GitHub comparison view, showing the changes made
since the last release.
Disconnecting from GitHub
Terminate an obsolete GitHub connection, if necessary.
Disconnecting individual apps
Individual apps can be disconnected in the GitHub pane of the
Deploy tab for the app.
Disconnecting account
You can disconnect your Heroku and GitHub accounts in the Applications
pane on your Dashboard account
page.
My Google-fu is failing me for what seems obvious if I can only find the right manual.
I have a Gitlab server which was installed by our hosting provider
The Gitlab server has many projects.
For some of these projects, I want that Gitlab automatically pushes to a remote repository (in this case Github) every time there is a push from a local client to Gitlab.
Like this: client --> gitlab --> github
Any tags and branches should also be pushed.
AFAICT I have 3 options:
Configure the local client with two remotes, and push simultaneous to Gitlab and Github. I want to avoid this because developers.
Add a git post-receive hook in the repository on the Gitlab server. This would be most flexible (I have sufficient Linux experience to write shell scripts as git hooks) and I have found documentation on how to do this, but I want to avoid this too because then the hosting provider will need to give me shell access.
I use webhooks in Gitlab. I am unfamiliar with what the very basics of webhooks are, and I am unable to locate understandable documentation or even a simple step-by-step example. This is the documentation from Gitlab that I found and I do not understand it: http://demo.gitlab.com/help/web_hooks/web_hooks
I would appreciate good pointers, and I will summarize and document a solution when I find it.
EDIT
I'm using this Ruby code for a web hook:
class PewPewPew < Sinatra::Base
post '/pew' do
push = JSON.parse(request.body.read)
puts "I got some JSON: #{push.inspect}"
end
end
Next: find out how to tell the gitlab server that it has to push a repository. I am going back to the GitLab API.
EDIT
I think I have an idea. On the server where I run the webhook, I pull from GitLab and then I push to Github. I can even do some "magic" (running tests, building jars, deploying to Artifactory,...) before I push to GitHub. In fact it would be great if Jenkins were able to push to a remote repository after a succesful build, then I wouldn't need to write my own webhook, because I'm pretty sure Jenkins already provides a webhook for Gitlab, either native or via a plugin. But I don't know. Yet.
EDIT
I solved it in Jenkins.
You can set more than one git remote in an Jenkins job. I used Git Publisher as a Post-Build Action and it worked like a charm, exactly what I wanted.
would work of course.
is possible but dangerous because GitLab shell automatically symlinks hooks into repositories for you, and those are necessary for permission checks: https://github.com/gitlabhq/gitlab-shell/tree/823aba63e444afa2f45477819770fec3cb5f0159/hooks so I'd rather stay away from it.
Web hooks are not suitable directly: they make an HTTP request with fixed format on certain events, in your case push, not Git protocol requests.
Of course, you could write a server that consumes the hook, clones and pushes, but a service (single push and no deployment) or GitLab CI (already implements hook management) would be strictly better solutions.
services are a the best option if someone implements it: live in the source tree, would do a single push, and require no extra deployment overhead.
GitLab CI or othe CIs like Jenkins are the best option currently available. They are essentially already implemented server for the webhooks, which automatically clone for you: all you have to do then is to push from them.
The keywords you want to Google for are "gitlab mirror github". That has led me to: Gitlab repository mirroring for instance. There seems to be no perfect, easy solution today.
Also this has already been proposed at the feature request forum at: http://feedback.gitlab.com/forums/176466-general/suggestions/4614663-automatic-push-to-remote-mirror-repo-after-push-to Always check there ;) Go and upvote the request.
The key difficulty now is how to store the push credentials.
I solved it in Jenkins. You can set more than one git remote in an Jenkins job. I used Git Publisher as a Post-Build Action and it worked like a charm, exactly what I wanted.
I added "-publisher" jobs that run after "" is built successfully. I could have done it in one job, but I decided to split it up. The build jobs are triggered by a web hook in GitLab; the publisher jobs are using a #daily schedule from the BuildResultTrigger plugin.
I have been trying to deploy from a GitHub repository to Heroku. For pushing my changes to GitHub I am using Mac UI Client for GitHub.
Now in the heroku app setup, I changed at https://dashboard.heroku.com/apps/myapp/settings . Here I made changes in option GitHub Rep (Link your app to a GitHub repository to see commit diffs in the activity log.). I added as my github-user/repository-name
Now when i use myappname.heroky.com I am redirected to a default page which says :
Heroku | Welcome to your new app! Refer to the documentation if you
need help deploying.
In the documentation it is all commands which is going over me since i use Github UI tool.
Any idea if this can be deployed w/o using the commands?
I am asking this particular thing, since last time I used AppHarbor and it simply pulled my github rep w/o any hiccups.
Adding your GitHub repo to the Heroku app settings will not set up automatic deployments. It just allows Heroku to provide commit information in the app logs.
To achieve what you are looking for, you need to set up continuous deployment (or "CD"). The easiest way to do this is with a continuous integration (or "CI") solution.
One common CI server is Jenkins, though that will require you to set it up manually. Nowadays, there are several automated CI/CD services you can take advantage of, including Travis, CircleCI, Codeship, Snap. All of them have options to automatically deploy to Heroku after building your app (which can be trigger by a push to GitHub).
I have a main app on heroku and another app A on git in location github:a.
I want to create, when it is necessary, copies of A as A1,A2,A3...AN as separate apps on heroku from my main app automatically with different parameters.
How can i do that?
Edit: This process should be done by my main app automatically.
Updating this answer due to Heroku command DEPRECATION:
heroku fork has been deprecated as a core command as of 12/01/2017.
You will need to install the heroku-fork plugin to continue using this command.
heroku plugins:install heroku-fork
Here is a link to the Github plugin repo.
Use heroku fork to copy an existing application, including add-ons, config vars, and Heroku Postgres data.
See this KB page: Forking Applications.
Heroku toolbelt now provides a fork method to clone an existing application, see my answer here :
how to clone a project on heroku
There is a new feature on Heroku called Review Apps. One can create copies of the app manually or set up automatic copies from new PRs on Github.
Read more at: https://devcenter.heroku.com/articles/github-integration-review-apps
Simply create new applications and push your code to them. If you need to copy data, checkout the pgbackups transfers.
For management purposes, check out this dev center article.
To do this programatically, you'll need to look at the Heroku gem, and then figure out a way of getting something to git push to the appropriate remote. I would be surprised if this was possible to be honest.
