使用dockerfile clone私人git repo

Question

我已经从似乎各种各样的工作dockerfile中复制了此代码，这是我的：

FROM ubuntu

MAINTAINER Luke Crooks "[e-mail]"

# Update aptitude with new repo
RUN apt-get update

# Install software 
RUN apt-get install -y git python-virtualenv

# Make ssh dir
RUN mkdir /root/.ssh/

# Copy over private key, and set permissions
ADD id_rsa /root/.ssh/id_rsa
RUN chmod 700 /root/.ssh/id_rsa
RUN chown -R root:root /root/.ssh

# Create known_hosts
RUN touch /root/.ssh/known_hosts

# Remove host checking
RUN echo "Host bitbucket.org\n\tStrictHostKeyChecking no\n" >> /root/.ssh/config

# Clone the conf files into the docker container
RUN git clone [e-mail]:Pumalo/docker-conf.git /home/docker-conf

这给我错误

Step 10 : RUN git clone [e-mail]:Pumalo/docker-conf.git /home/docker-conf

Please make sure you have the correct access rights
and the repository exists.

这是我第一次使用dockerfiles，但是从我阅读的内容（以及从有效的配置中获取）来看，我不明白为什么它不起作用。

我的id_rsa与我的dockerfile位于同一文件夹中，并且是我的本地密钥的副本，可以克隆此存储库。

编辑：

在我的dockerfile中，我可以添加：

RUN cat /root/.ssh/id_rsa

并且它会打印出正确的密钥，因此我知道它已正确复制。

我还尝试按照诺亚的建议去做：

RUN echo "Host bitbucket.org\n\tIdentityFile /root/.ssh/id_rsa\n\tStrictHostKeyChecking no" >> /etc/ssh/ssh_config

可悲的是这也行不通。

我的密钥受到密码保护，这是导致问题的原因，下面列出了一个工作文件（以帮助将来的Google员工）

FROM ubuntu

MAINTAINER Luke Crooks "[e-mail]"

# Update aptitude with new repo
RUN apt-get update

# Install software 
RUN apt-get install -y git
# Make ssh dir
RUN mkdir /root/.ssh/

# Copy over private key, and set permissions
# Warning! Anyone who gets their hands on this image will be able
# to retrieve this private key file from the corresponding image layer
ADD id_rsa /root/.ssh/id_rsa

# Create known_hosts
RUN touch /root/.ssh/known_hosts
# Add bitbuckets key
RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts

# Clone the conf files into the docker container
RUN git clone [e-mail]:User/repo.git
