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.

I am new to Heroku and I keep getting the above error - everything looks good to go when I deploy in heroku, connect to my github repo etc.. but I keep getting this error.
Its a node/express app and works exactly as I'd like locally but it won't deploy. Any help would be appreciated.
For getting logs of particular heroku app, use:
heroku logs --app=app_name
For example: your app name is 'chatapp'
heroku logs -app=chatapp
just run the command with the --app flag, followed by the app name.
I like how the --app flag is "mandatory" according to the official documentation, but the lone usage example in the official documentation doesn't use the --app flag.
Anyway, it's not really mandatory. It's just implicit, usually. You have to tell Heroku which app you're using, with something like:
$ heroku git:remote -a your_app_name
and then it stops wondering which app to run these commands on.
you did not set git remote to your application, do that first by,
heroku git:remote -a your_app_name
To expand a little further on this (just for the benefit of other new users encountering a similar issue) - below is an example of a command you could enter in macOS Terminal:
heroku logs --tail --app yourexampleservername
If you have deployed yourexampleservername to Heroku, this should then display a log.
I'm trying to run commands for my heroku app in my console, but it keeps telling me "Couldn't find that app." even though when I run heroku apps in my console it tells me I have one app called worldofwarcraft-api
So heroku recognizes my app in the apps list, but I can't run any commands to access it. The line I want to run is
heroku ps:scale web=1 --app worldofwarcraft-api
I'm trying to troubleshoot why my API returns a 503 when I try to make a GET request to it. This is the fix the heroku faq told me to try, but it's just telling me it can't find my app.
I'm wondering if it has something to do with the fact that I deployed my API from github, rather than running the heroku setup in my console. I don't know if that would effect my ability to run heroku commands on the app in my local console.
Apologies if my formatting is off a bit. I'm still getting used to this site.
In my case, someone renamed GitHub repo and I tried to find Heroku app with new GitHub name
It helps me
heroku apps
heroku git:remote -a YOUR_APP
Solved it. Just sharing for future searches.
The issue was fixed by running git init and then heroku git:remote -a worldofwarcraft-api in my command line while inside my repositories folder. This initialized git in the repo and then set the heroku git remote to that repository.
Hopefully, this helps anyone else who had a similar issue.
Just an easy way to solve this issue:
1st: Add the command into your terminal: $ heroku apps
If you already logged into your heroku account from your terminal, all your apps will appear as a list like this:
your-project-name-1
your-project-name-2
your-project-name-3
your-project-name-4
2nd: Then chose which one you are needing to connect with the following command:
$ heroku git:remote -a your-project-name-2
If you've done the connection properly you'll receive the following output:
set git remote heroku to https://git.heroku.com/your-project-name-2.git
For my case, I was renaming my github repository.
You can find it in your repository settings then just rename it, it appears in the first place.
Then you can continue with git init again to re-initiate your existing git repository and then set your heroku remote with your heroku apps new name heroku git:remote -a YOUR_APP_NAME
If the app belongs to a team that you participate in, you have to specify the team option in the commands to see the app:
E.g:
heroku apps -t <team name>
or
heroku ps:scale web=1 --app worldofwarcraft-api -t <team name>
I am using Heroku toolbelt:
Command line: >heroku create app1 (root application)
Delete app1 from Heroku Dashboard in the browser.
Command line: >heroku create app2 (from the same root application)
I wanted to add variable: heroku config:set MYVAR=value
Then I get the error:
Setting MYVAR and restarting app1... !
! Couldn't find that app.
How can I switch to the new app (app2) and remove app1 completely?
Try destroying the old app:
heroku apps:destroy app1
Note that this will permanently and irrevocably destroy app1.
You can change the app from app1 to app2 by using
heroku git:remote -a app2
heroku apps:destroy --app app1 --confirm app1
heroku git:remote -a app2
USE heroku git:remote which adds a git remote to an app repo
USAGE
$ heroku git:remote
OPTIONS
-a, --app=app the Heroku app to use
-r, --remote=remote the git remote to create
--ssh-git use SSH git protocol
DESCRIPTION
extra arguments will be passed to git remote add
EXAMPLES
set git remote heroku to https://git.heroku.com/example.git
`$ heroku git:remote -a example`
set git remote heroku-staging to https://git.heroku.com/example-staging.git
`$ heroku git:remote --remote heroku-staging -a example`
open your Dashboard and select the app you want to delete.
Now that you are in the desired application click on the Settings tab.
Scroll to the bottom of the page and click the "Delete app..." button.
Follow the onscreen instructions to confirm the apps deletion.

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.

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
