How to specify ssh key for git repository?

[Sogl]

I have ssh key in ~/.ssh/config:

Host bitbucket.org
  IdentityFile ~/.ssh/my_key

This key is added in my repo and test connection works fine:

laradock@f56ba1192e13:/var/www/sogl$ ssh -T git@bitbucket.org
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled

BUT dep deploy command don't work:

Cloning into '/home/*****/public_html/*****/releases/28'...
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
Connection to *server* closed.

I have lines with the same key for the server:

host('*server*')
    ...
    ->configFile('~/.ssh/config')
    ->identityFile('~/.ssh/my_key')
    ...;

And I can't find any key option for repository:

// Project repository
set('repository', 'git@bitbucket.org:Me/my-repo.git');

Any ideas?

Deployer 6.8.0

Your host doesn’t have same key. Two options: use agent forwarding or a separate key specially for your host (deploy keys).

[Sogl]

use agent forwarding

According to documentation, it's used by default
I added line host(*server*)->forwardAgent() but nothing changed.

separate key specially for your host (deploy keys).

Do you mean creating a Bitbucket key on the remote/deploy server?

[antonmedv]

Yes, usually it is called deploy keys.

[Sogl]

But why agent forwarding isn't working?

[antonmedv]

Can’t tell. Try to debug using -vvv

[antonmedv]

For me it’s working.

[Sogl]

How to check that's agent forwarding works? In which line of debug output?

[Sogl]

Agent forwarding finally works with:

eval `ssh-agent -s`
ssh-add ~/.ssh/my_key

Also +1 line ForwardAgent yes in ~/.ssh/config, I don't know if it helped or not.

P.S. The last step is to find how to register it in Dockerfile
