Dokku password prompt even after setting up ssh keys


I’m posting a question here as a last resort, before I throw my computer against the wall (not really), after multiple failed attempts to deploy a Django app through the preconfigured dokku droplets.

I have gone through several droplets, created, destroyed, spent hours going through forums, blogs and stackoverflow, but no matter what I’ve done I still get stuck at the very last stage -that damn password.

The website I’ve been using this tutorial LINK but always get stuck at

git push production master

I’ve added my local (Macbook) public key ( to both the root and dokku users, and am able to ssh into them without password prompts. I’ve configured my git account (git --global?) correctly. I’ve used

cat ~/.ssh/ | ssh root@your.dokku.ip "sudo sshcommand acl-add dokku [description]"

but again, no matter what I do, I still get the password prompt.

HELP!!! What am I doing wrong? Any and all help would be really appreciated.

Thank you in advance…

EDIT: Forgot to ask… What about adding the root ssh key to the dokku user’s authorized hosts? I’ve also added the root key to my github account…


So, it seems that this command is outdated:

cat ~/.ssh/ | ssh root@your.ip.address "cat >> ~/.ssh/authorized_keys"

But this works for me:

cat ~/.ssh/ | ssh root@your.ip.address "sudo sshcommand acl-add dokku [description]"

same problem here!! anyone from DO can make a response?

I’ve got an answer below - basically you have to tell git to use ssh!

Any progress on this? Seems like a very common problem with no reliable solution.

I ran cat ~/.ssh/ | ssh root@my.dokku.ip "sudo sshcommand acl-add dokku firstdokku"

Same issue…

having the same issue.

I’m having the same problem. Not sure how to proceed. Anyone get a fix for this yet?

Weird. I ran into this issue this morning on a fresh Dokku instance and that fixed it for me. So your remote look like (when doing git remote -v:

production dokku@[whateveryoururlIs]:[whateverYourRemoteDokkuRepoIs] 

and when you try to do a push with git push production master you still get a prompt for password?

@chaseadamsio yep… tried [macbook] and and macbook and “macbook”, with no luck. Thanks for replying!

Make sure you add your SSH key to the authorized_keys for the dokku user as well as root! i.e. in /home/dokku/.ssh/authorized_keys

For those still getting this problem try updating your ~/.git/config with:

IdentityFile ~/.ssh/id_rsa(.pub)
User dokku

Ok, it is the way how i resolved the problem:

  1. Open config file in .ssh folder
  2. Add ‘.pub’ to IdentityFile
  3. save file and try to do “ssh root@[droplet id]”
  4. you will get error
  5. remove ‘.pub’ from config file
  6. do “ssh root@[droplet id]”
  7. in new terminal tab try to push remote branch

I hope it will help somebody =)

I had the same problem, and it was because I had a misconfiguration inside ~/.ssh/config

spent a few hours tuning SSH & Dokku, but still cant make it work for me Could anyone look into this issue?
