docker - [email protected]: Permission denied - fatal: Could not read from remote repository, from Dockerfile

Question

I have a Dockerfile with the following RUN instruction:

RUN pip install -r ./private_requirements.txt

The private_requirements.txt file is an ssh URL pointing to a GitLab repository:

git+ssh://[email protected]/organization/viiaa/[email protected]

When I do docker build when the RUN instruction is evaluated, I got the following output:

> [intermediate 9/9] RUN pip install git+ssh://[email protected]/organization/viiaa/[email protected]:

I already added my public key to gitlab profile keys

Answer 1

Check your error

#13 1.286   Load key "/root/.ssh/id_rsa": invalid format

Go there and check your private key. It should have the form

-----BEGIN OPENSSH PRIVATE KEY-----
......
......
......
......
......
......
......=
-----END OPENSSH PRIVATE KEY-----

It can be that you have copied in id_rsa the content of the public key and not the private key itself.

Public key must be saved in the same folder /root/.ssh/id_rsa.pub . It must be a different file with the name id_rsa.pub
