Docker container build with git ssh access, Load key "/root/.ssh/id_rsa": invalid format

Folks, After following a few threads on how to add ssh keys to the docker container for the application build phase, I am getting an interesting error:

Load key "/root/.ssh/id_rsa": invalid format

My Dockerfile:

RUN mkdir /root/.ssh/
ADD serviceBitbucketKey.ssh /root/.ssh/id_rsa
RUN chmod 400 /root/.ssh/id_rsa

RUN touch /root/.ssh/`known_hosts
RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts
RUN git ls-remote [email protected]:orgName/repo.git
RUN git config --global url.ssh://[email protected]/.insteadOf https://bitbucket.org/

I do know the key is fine... it was generated via

ssh-keygen -t rsa -b 4096 -f serviceBitbucketKey.ssh

Suggestions? Thanks!

Try, assuming, as detailed in Adiii's answer, that the permissions are OK, to generate a key using the old PEM format (instead of the new OpenSSH one):

ssh-keygen -t rsa -P "" -C "your-email-address" -m PEM

I thing its permission issue if the key is valid, try with this

FROM alpine:3.7
#copy key
ADD serviceBitbucketKey.ssh /root/.ssh/id_rsa

#install git
RUN apk --no-cache update git

#set proper permission
RUN chmod 600 /root/.ssh/id_rsa && \
touch /root/.ssh/known_hosts && \
ssh-keyscan bitbucket.org > ~/.ssh/known_hosts
RUN git ls-remote [email protected]:myorg/myrepo.git
