python - 在 Dockerfile 中的 Docker 镜像中复制 gitlab 项目

Question

我正在尝试将 gitlab 项目复制到我的 docker 映像中，以便可以在我的 python 脚本中使用它。我的 DockerFile 一直运行到这一行：

RUN \
### ssh configuration, see https://docs.gitlab.com/ee/ci/ssh_keys/#ssh-keys-when-using-the-docker-executor
# run ssh-agent inside build environment
eval $(ssh-agent -s); \
# add ssh-key from GitLab variable to ssh agent store incl. fixing line endings
echo "${SSH_PRIVATE_KEY}" | tr -d '\r' | ssh-add -; \
# create the SSH directory and give it the right permissions
mkdir -p ~/.ssh; \
# Allow access to gitlab.your.lan
echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config; \
chmod 700 ~/.ssh; \
\
git clone ${BACKEND_PATH}

错误代码：

+ echo 
+ ssh-add -+ 
tr -d \r
Could not open a connection to your authentication agent.
+ mkdir -p /root/.ssh
+ echo -e Host *\n\tStrictHostKeyChecking no\n\n
+ chmod 700 /root/.ssh
+ git clone /backend
fatal: repository '/backend' does not exist
+ docker build . --force-rm --build-arg SSH_PRIVATE_KEY=config/backend_key.pem
/bin/sh: 1: docker: not found
