Using the heroku docker:release command, how can I specify which app to release to? I can't see from any documentation whether there's any switch for this purpose.
Heroku commands take their context from the directory you are in when you run them.
Go into the directory from where you did heroku create then run heroku docker:release.
If you haven't used heroku create, then you can specify the app name with the --app <APP NAME> command line parameter. for instance, if you were to release to the app named f00 you would type:
heroku docker:release --app f00

I've got a problem when I upload my project on Heroku. I've trying changing value of socket.io and MongoUrl, but I get this error:
Error: Missing required flag:
› -a, --app APP app to run command against
This has nothing to do with any of your files. It's an argument that you must provide to the Heroku CLI itself, e.g.
heroku config:set SOME_VARIABLE=some_value -a myapp
where myapp is the name of your Heroku app.
The -a / --app argument is required when heroku can't figure out what app to connect to, either bcause there is no Heroku remote configured or because there is more than one Heroku remote configured.

From a remote shell, using the Heroku toolbelt, it's pretty easy to trigger a db backup with:
heroku pg:backups:capture --app my-app
But how can I do that from a script running on the app itself? Something triggered from the heroku scheduler or manually like:
heroku run node myScript.js --app my-app
I have psql available so maybe that's an option although I don't know where to write to.
I don't see a way to do this via API here: https://devcenter.heroku.com/articles/platform-api-reference
I have two git branches, staging and production, and I deployed them on Heroku in the same Heroku acccount. Suppose my app names are app1.heroku-app.com and app2.heroku-app.com and the remote names are heroku-staging and heroku-production,respectively. I deployed both apps on Heroku. After I login to Heroku from the console using heroku login and then try to access a Rails console using heroku run rails c, I get this message :
▸ multiple apps in git remotes
▸ remotes: heroku-staging heroku-production
How can I access a console?
If there's only one Heroku remote, heroku can infer which you want. When there are multiple (or if you want to access an application that doesn't have a remote in this Git repo, or when you're not in a Git repo at all), you need to use the --app option to specify which application you want a console on.
$ heroku --help
Usage: heroku COMMAND [--app APP] [command-specific-options]
$ heroku run rails c --app app1
$ heroku run rails c --app app2
In addition to being able to specify the app as a per-command flag, if you'd like for there to be a default environment, setting the environment variable HEROKU_APP to the app you want will make it so that heroku commands don't rely on git config.
$ heroku logs

I've an existing project that works fine on another machine, but I've just upgraded and from within the project development directory, everytime I run a heroku command I have to post-fix it with --app
I feel like I've missed an application setup stage, but I can't figure out what, as everytime it states:
Run this command from an app folder or specify which app to use with --app APP.
Help appreciated.
You can solve this by adding the Heroku app to your .git/config folder.
If you are in the root of your project, run the following command:
git remote add heroku git#heroku.com:appname.git
This will set a line in your .git/config file which the heroku command line tool uses to figure out what app you're using :)
In other words, your local repo doesn't have Heroku app URL configured against an app name
Similarly what we do with git remote add ( we pass git URL as a destination for push/pulling of code )
that how our git know which repo/URL to hit (push/pull from )
Heroku also follows the same method/process.
All you have to do is add Heroku app URL (so that ur Heroku command have a reference for app URL )
it will know against which URL you are running your command against
To confirm if remote named Heroku has been set for your app:
git remote -v
if not configured or if you want it for an existing app
heroku git:remote -a app_name
it's a way to link your folder to the Heroku app
The Heroku recommended way:
heroku git:remote -a my-heroku-app-id -r what-i-want-to-call-it
Source: https://devcenter.heroku.com/articles/git
Run this command from an app folder or specify which app to use with --app APP
The other answers address the first part of that statement, it is perfectly acceptable to run heroku commands in any directory. For example I have a customer facing front end project /front-end and a rails based /back-end project. I often work in the /front-end directory and if I have to connect to the production database I'll run heroku run rails c -a back-end. After I exit irb then I'm back in my desired directory.
How do you specify the app you want when you log in to Heroku from the command line?
I was trying to check the logs so when I first logged in I tried:
Heroku logs
this then told me:
! No app specified.
! Run this command from an app folder or specify which app to use with --app <app name>
I then tried:
heroku --app my-appname
but i get:
`--app` is not a heroku command.
I have tried all combinations.
You still need to include the command:
heroku logs --app app-name
You can also use -a instead of --app:
heroku logs -a app-name
Another option is to associate your (git) project to Heroku. From heroku open - no app specified:
$ cd app-dir
$ heroku git:remote -a app-name
$ heroku logs
Try this:
heroku git:remote -a [app_name]
This should allow you to call commands without having to specify which app you want them to be called on.
You could try adding --app app-name after you sentence.
Example: $ heroku domains:add your-domain --app app-name
Heroku CLI automatically detects the app name by scanning the git remotes for the current working copy.
If you're not in the app's local git clone, you need to specify the app name:
heroku logs --app app-name
or
heroku logs -a app-name
or by specifying the remote name:
heroku logs --remote production
You can reference this part of the Heroku documentation:
https://devcenter.heroku.com/articles/using-the-cli#app-commands
From my tests the Heroku CLI will infer the app from the current Git remote.
So to change to the "test" app:
git config heroku.remote test
And to come back to the default "heroku" application, which is probably your production app:
git config heroku.remote heroku
Not sure this is a good idea though...
For future solution seekers-
The error says a possible solution.
Run this command from an app folder
cd to the app directory root, then run your desired command.
