I'm currently using Heroku Pipeline feature for automatically detecting, building and deploying pull requests for review.
✓ Create new review apps for new pull requests automatically
URL pattern
Pattern: Random pipeline-xxxxxx-xxxxxx.herokuapp.com
The problem is that my app needs a combination of 2 buildpacks in a specific order in order to boot properly.
The main/production app has this settings and it works fine(e.g. after each time a PR is merged).
From what I see Review Apps doesn't have a concept of buildpack settings and it tries to autodetect it each time.
What I've tried:
Open the latest Review App, set buildpacks, rebuild or push a new commit. It works fine in that Pull Request/branch/Review App but for each new PR this process has to be repeated manually.
Is there any way to overcome this issue?
In case you have a similar issue, one approach that you can use(that worked for me)
app.json Heroku's convention file where you can list your buildpacks among many other settings.

I have a Golang app running on Google Cloud App Engine that I can update manually with "gcloud app deploy" but I cannot figure out how to schedule automatic redeployments. I'm assuming I have to use cron.yaml, but then I'm confused about what url to use. Basically it's just a web app with one main index.html page with changing content, and I would like to schedule automatic redeployments... how do I have to go about that?
If you want to automatically re-deploy your app when the code changes, you need what's called CI/CD (Continuous integration/deployment). What a CI does is, for each new commit to your repository, check out the new code and run a test script. If all the tests pass (or if you don't have any tests at all), the CI server can then deploy your code to App Engine, all automatically.
One free (for open-source projects) CI provider is Travis CI. To configure it, you need to make an account with Travis, and a file called .travis.yml in the root of your repository. To set up App Engine deploys, you can follow this guide to set up a service account and add the encrypted file to your repo. It will run a gcloud app deploy from a container on their servers, whenever you push code to a certain branch (master by default) in your repo.
Another option, which avoids setting up CI at all, is to simply change your app to generate the dynamic parts of the page when it gets requested. Reading the documentation for html/template would point you in the right direction.
I am investigating adding an app.json file to my heroku pipeline to enable review apps.
Heroku offers the ability to generate one from your existing app setup, but I do not see any way to prevent it from automatically committing it to our repository's master branch.
I need to be able to see it before it gets committed to the master branch because we require at least two staff members to review all changes to the master branch (which triggers an automatic staging build) for SOC-2 security compliance.
Is there a way that I can see what it would generate without committing it to the repository?
I tried forking the repo and connecting the fork to it's own pipeline, but because it did not have any of our heroku add-ons or environment, it would not work for our production pipeline.
I am hesitant to just build the app.json file manually - it seems more prone to error. I would much prefer to get the automatically generated file and selectively remove items.
As a punchline to this story, I ended up investing enough time into the forked repository on it's own pipeline to demonstrate a POC
When you generate your app.json file, it should take you to a secondary screen that has the full app.json in plaintext at the bottom.
Why not open a PR with its contents in your project root. Once it's detected on the repository Heroku shouldn't ask you to regenerate it again.
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.
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.
