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 : 
ShareaDreamKP)

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 ubuntu@ec2-52-29-215-157.eu-central-1.compute.amazonaws.comPseudo-terminal 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 (https://confluence.atlassian.com/bitbucket/use-ssh-keys-in-bitbucket-pipelines-847452940.html#UseSSHkeysinBitbucketPipelines-UsemultipleSSHkeysinyourpipeline)

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 :

pipelines:
  branches:
    dev:
      - step:
          script:
            - mkdir -p ~/.ssh
            - cat my_known_hosts >> ~/.ssh/known_hosts
            - (umask  077 ; echo $MY_SSH_KEY | base64 --decode > ~/.ssh/id_rsa)
            - ssh -i  ubuntu@ec2-52-29-215-157.eu-central-1.compute.amazonaws.com
            - sudo npm run dev

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

Please, help me !

What worked for me is to put the SSH Key from your screenshot into the /home/ubuntu/.ssh/authorized_keys file on a new line. The .ssh folder must be set up with drwx------ or the server will refuse it...that was a gotcha for me.

It looks like you already have your known_hosts set in Pipelines so that should be ok.

Then you should be able to just

ssh ubuntu@ec2-52-29-215-157.eu-central-1.compute.amazonaws.com
