docker CMD中的命令替换

Question

使用：

CMD ["$(pipenv --venv)/bin/python3", "main.py", "/root/uploads"]

导致docker run错误：

Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"$(pipenv --venv)/bin/python3\\\": stat $(pipenv --venv)/bin/python3: no such file or directory\"\n"

有没有办法在CMD部分进行评估命令替换，如$(pipenv --venv)/bin/python3？

Answer 1

将其更改为

CMD ["bash", "-c", "$(pipenv --venv)/bin/python3 main.py /root/uploads"]

如果仍有问题，请将$更改为$$
