I have the following release phase in my Procfile:
release: bundle exec rake db:migrate
It works great when I merge PR's into my staging and production apps, but it fails when running on a new review app. The Heroku docs say that the release phase is run after a successful build, so I don't know why it can't find bundle.
This is my output
heroku releases:output 9 --app my-app-pr-253
/bin/sh: 1: bundle: not found
For Heroku's review apps, you must specify all buildpacks and ENV vars you need in the app.json file. You can either manually create one, or have Heroku generate one for you.
https://devcenter.heroku.com/articles/github-integration-review-apps#app-json
Confirm that in your app.json you have specified
1) The required buildpacks https://devcenter.heroku.com/changelog-items/670. Since you are using bundle I'm guessing heroku/ruby will be one. Below is an example.
"buildpacks": [
{
"url": "https://github.com/heroku/heroku-buildpack-ruby.git"
},
2) Also make sure you specify any config variables that you want to inherit from the app off which your review app is being built. https://devcenter.heroku.com/articles/app-json-schema#env Missing one of these could also be causing a build to fail.
If neither of these work, try checking the logs for your heroku app. Watch the ones in the Heroku GUI during the build. Also try to tail the logs in the CLI.
heroku logs -t -a <review_app_name>
I figured out my problem. It was a silly typo:
"buildpacks": [
{
"url": "heroku/ruby",
"url": "https://github.com/guillaume-tgl/heroku-buildpack-ghostscript.git"
}
]
should have been:
"buildpacks": [
{ "url": "heroku/ruby"},
{ "url": "https://github.com/guillaume-tgl/heroku-buildpack-ghostscript.git" }
]

I would like to provide a button from github to directly deploy an app.
Its a go application which serves some website.
Now for persistent data it requires an addon "Heroku Postgres".
I tried defining a heroku.yml with:
setup:
addons:
- plan: heroku-postgresql
I tried app.json with:
{
"addons": ["heroku-postgresql:hobby-dev"]
}
But it does nothing at all, it never adds the addon. I know I can add it manually through the website or CLI, but I want a fully automatic way - if that is possible.
It should look something like this
"addons": [
{
"plan": "heroku-postgresql",
"options": {
"version": "12"
}
}
]
Example app.json from heroku
I am setting up a Heroku pipeline and I want to add the "add-on" attribute however I did not see them be applied to my environment.
The format of the add ons block is:
"addons": [
"sendgrid",
{
"plan": "deployhooks:http",
"as": "SLACK-ENG-STATUS",
"options": {
"url": "THIS IS A RANDOM URL"
}
}
],
Is that the correct syntax to create the add-on? I do not see the configuration in the staging app when I directly deploy to it.
Do you expect your addon to be created on deploy? Because that is not how the app.json works. The app.json only created your addons for:
Review apps (https://devcenter.heroku.com/articles/github-integration-review-apps#app-json)
When you use the platform API to create your app (https://devcenter.heroku.com/articles/setting-up-apps-using-the-heroku-platform-api), including through the Heroku Button
If you already have an existing app, entries in the app.json will not modify it on deploy.
All,
Attempting to use Heroku's new-ish Continuous Integration service but it doesn't appear to want to play well with its own framework.
I've setup my Heroku Pipeline as outlined in the CI article: https://devcenter.heroku.com/articles/heroku-ci#configuration-using-app-json.
My deployments to review apps work correctly.
But my CI tests error with the following
app.json
"buildpacks": [
{ "url": "heroku/jvm" },
{ "url": "heroku/nodejs" }
],
Results in
$ heroku ci:debug --pipeline mypipelinename

error downloading buildpack
I'm using the JVM buildpack so that I may install liquibase which manages version control for my Postgresql DB, but I'm actually deploying a NodeJs app.
Why would my "Review App"s deploy without problems but die during "Test Setup"?
I managed to get past this by using the github url for the node buildpack
"buildpacks": [
{
"url": "https://github.com/heroku/heroku-buildpack-nodejs"
}
],
I imagine it will work the same for jvm
When you deploy the https://github.com/SuaveIO/heroku-getting-started example project to Heroku, the correct fsharp buildpack is used (specified in the app.json file). Like so:
{
"name": "Sample Suave web app",
"description": "Sample single-script Suave web app, deployable to Heroku.",
"website": "http://suave.io/",
"repository": "https://github.com/SuaveIO/heroku-getting-started",
"logo": "https://raw.githubusercontent.com/SuaveIO/suave/gh-pages/images/logo.gif",
"env": {
"BUILDPACK_URL": "https://github.com/SuaveIO/mono-script-buildpack.git"
}
}
However, if you want to deploy directly from github, the custom buildpack isn't used.
The only way to get this running is by manually specifying the BUILPACK_URL config var in the web api of the web app. So, why is this config var specified by the app.json not used? Is there another way of specifying this config var, without having to add this manually to the dashboard -> settings -> config vars of the web app?
Instead of using app.json, you can use heroku buildpacks command to set/remove/clear buildpacks. Here is the output of command heroku buildpacks -h:
buildpacks:add BUILDPACK_URL # add new app buildpack, inserting into list of buildpacks if neccessary
buildpacks:clear # clear all buildpacks set on the app
buildpacks:remove [BUILDPACK_URL] # remove a buildpack set on the app
buildpacks:set BUILDPACK_URL # set new app buildpack, overwriting into list of buildpacks if neccessary

I know the slug compiler removes the .git directory when creating a heroku slug, but is there any way to configure Heroku so that I can access the currently running git commit number from within my scripts?
I'd like to be able to have a small link on my sinatra app (run within Heroku) which says "running version e72fb274a0" (or something similar). How can I retrieve this, or force the slug compiler to add it to an environment variable?
PROGRESS:
I reckon the best way to do this is to make a custom buildpack which writes the git commit version number to the heroku slug before the .git directory is deleted.
I've tried to do this (see my fork of the ruby buildpack) but the line I've added – line 23 – doesn't seem to be doing the job. Heroku sees & uses the new buildpack, but doesn't seem to write the file to the slug.
Anyone have any idea why my custom buildpack isn't working as expected?
Thanks,
JP
A couple of options...
SOURCE_VERSION environment variable (build-time)
Since 1st April 2015, there's a SOURCE_VERSION environment variable available to builds running on Heroku. For git-pushed builds, this is the git commit SHA-1 of the source being built:
https://devcenter.heroku.com/changelog-items/630
(thanks to #srtech for pointing that out!)
An example of me using that variable in a build - if you look at the HTML served by the deployed app, you'll see the commit id is coming though in an HTML comment near the very bottom: https://gu-who.herokuapp.com/
/etc/heroku/dyno metadata file (run-time)
Heroku have beta functionality to write out a /etc/heroku/dyno metadata file onto your running dyno. If you email support you can probably get added to the beta. Here's a place where Heroku themselves are using it:
https://github.com/heroku/fix/blob/6c8ab7a/lib/heroku_dyno_metadata.rb
The contents look like this:
{
"dyno":{
"physical_id":"161bfad9-9e83-40b7-b385-78305db2f168",
"size":1,
"name":"run.7145"
},
"app":{
"id":null
},
"release":{
"id":50,
"commit":"2c3a0b24069af49b3de35b8e8c26765c1dba9ff0",
"description":null
}
}
..so release.commit is the field you're after. I used to use this method until the SOURCE_VERSION variable became available.
In 2018 this is what you want:
https://devcenter.heroku.com/articles/dyno-metadata
heroku labs:enable runtime-dyno-metadata -a <app name>
You can run a script before deploy that store this information (maybe on a YAML)
using these a = `ls` (note that is not ' "apostrophe" sign is ` "inverse accute" sign)
the a variable will have the result of this bash command,so you can do
git = `git log`
and then find the information you want it and store it.
So you will be able to retrieve it later.
Did this helped ?
