I'm using private keys for downloading my repository from Github in my Docker file. I have something like this:
RUN mkdir -p /root/.ssh && echo "$MY_PRIVATE_KEY" >/root/.ssh/id_rsa && chmod 0600 /root/.ssh/id_rsa && ssh-keyscan github.com >> /root/.ssh/known_hosts && cat /root/.ssh/known_hosts && ssh -vvv git@github.com && pip install git+ssh://git@github.com/my_project.git@v1.0.0 && rm /root/.ssh/id_rsa
Where MY_PRIVATE_KEY is an argument. I'm not able to re-create this key.
My issue is that during connection process I'm getting the following error:
key_load_private_type: incorrect passphrase supplied to decrypt private key
Is it possible to skip passphrase somehow?
The passphrase is required to decrypt the key. You can't "skip" it. You could remove the passphrase on the key using ssh-keygen -p (see the man page for details).
You may want to investigate the use of a GitHub Deploy Key, which is a per-repository ssh key that grants read-only access to the repository. These are meant to solve exactly the situation you find yourself in: needing to automaticaly deploy software from a GitHub repository that requires authentication.
Your MY_PRIVATE_KEY seems to be passphrase-protected (a key with an empty passphrase is not the same as a non-encrypted key).
The key in .ssh/id_rsa is normally not passphrase-protected, instead it is protected by permissions to allow only owner access (0600).
You can remove the passphrase from your key using OpenSSL like this:
set MY_PRIVATE_KEY = `echo $MY_PRIVATE_KEY | openssl rsa`
The contents of id_rsa should look like:
-----BEGIN RSA PRIVATE KEY-----
. . .
-----END RSA PRIVATE KEY-----
I had the similar issue and it turns out the reason is the ssh key was copied differently due to the Makefile
