SSH connection failed with pipeline

Hello,

I tried to connect to ssh with pipelines, but got this error : 

 

Pseudo-terminal will not be allocated because stdin is not a terminal. 
ssh_askpass: exec(/usr/bin/ssh-askpass): No such file or directory
Permission denied, please try again.

 

I used the bitbucket keys, and installed them on my server.

Was wondering if it could from the docker image. I used the default one.

Any suggestion ?

Thanks

For those who ask, the only thing that worked for me is to use ssh-agent (see the answer before : I can't copy and paste it here because of the spam filters of this forum)

The first line is resolved by adding -T to the ssh command, whic removes the need for an interactive terminal.

Stays the ssh_askpass command ?

I think this is linked to the fact that bitbucket SSH key has provided a passphrase. So I need to enter this passphrase (which I don't know) in order this to work. 

I could ssh my ubuntu server without any problem after having created a key in bitbucket pipelines as describred in doc.

I use the node:6.9.4 image and simply added 

ssh -t user@my.server.org "cd /var/my/path ; yarn install -prod"

in my pipeline script.

Did you add the target server in known_hosts ?

What is the line in the script that throws the message ?

Thanks for your answer.

I didn't add the target server in known_hosts because bitbucket asks for the key fingerprint of the server. I thought it was sufficient.

But I finally managed to make it work by adding :

- eval `ssh-agent -s`
- ssh-add ~/.ssh/id_rsa
- ssh-add -l

before the ssh command, if I use a custom made key.

This trick doesn't work for bitbucket keys, but I should try to add this known_hosts file.

So I had a look, and know_hosts contains the good server key.

I tried your image and it seemed to change something but I think my server is rejecting my IP now after too much tries... 

You do not need to provide to Bitbucket the key fingerprint of your server; it is computed using the address (or name) you provide in Pipeline settings.

 

Yes, you provide the server, and you fetch the fingerprint. Then bitbucket add it to the known_hosts (I checked and it is what it does).

 

Ok, so I retried what you told me, and it still doesn't work. I will stick to ssh-agent then...
