Bitbucket Pipelines : SSH connection to AWS EC2

I'm trying to connect in SSH to my AWS EC2 into my bitbucket pipelines.

I've generate and setup a KEY pair in AWS (Key pair name : 

From this, I add the public key and private key into my bitbucket SSH keys


I also add all my know host.

Then, when I try to connect in SSH using this :

"ssh will not be allocated because stdin is not a terminal.Permission denied (publickey)."

It's not working...

So I try to follow the guide to use multiple SSH keys (

a) I have put my base64 keys into my Environment variables as "MY_SSH_KEYS"

b) My public key is installed on AWS (/home/ubuntu/.ssh/authorized_keys)

c) I try to add manually a the root of my repository a my_known_hosts file with my pubic key and my host.


d) I change my pipelines to this :

      - step:
            - mkdir -p ~/.ssh
            - cat my_known_hosts >> ~/.ssh/known_hosts
            - (umask  077 ; echo $MY_SSH_KEY | base64 --decode > ~/.ssh/id_rsa)
            - ssh -i
            - sudo npm run dev

Still not working... I don't know what I can do !

Please, help me !

Then you should be able to just
