在基于图像的 Python 中,我想使用 go package gnostic 运行一个命令 (*):
RUN gnostic --grpc-out=test test/openapi/loyalty-bff.yaml
我确实写了以下dockerfile:
FROM golang:1.17 AS golang
RUN go get -u github.com/google/gnostic@latest
RUN go get -u github.com/googleapis/gnostic-grpc@latest
FROM python:3.7.10
WORKDIR /app
ADD requirements.txt /app/
RUN pip install -r requirements.txt
ADD . /app/
COPY --from=golang /go/bin/gnostic /go/bin/gnostic-grpc
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "5000"]
运行命令 (*) 时出现错误:
Command 'gnostic --grpc-out=loyalty-bff-1634180849463365375 loyalty-bff-1634180849463365375/loyalty-bff.yaml' returned non-zero exit status 127.
另一方面,我可以在不使用多阶段时运行。替换为在基于镜像的 go 中安装 python,但是构建时间很长:
FROM golang:1.17
WORKDIR /app
RUN go get -u github.com/google/gnostic@latest
RUN go get -u github.com/googleapis/gnostic-grpc@latest
RUN apt-get update
RUN apt-get install -y build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev wget libbz2-dev
RUN wget https://www.python.org/ftp/python/3.7.8/Python-3.7.8.tgz
RUN tar -xf Python-3.7.8.tgz
RUN cd Python-3.7.8 \
&& ./configure --enable-shared \
&& make && make install
RUN apt-get install python3-pip -y
ADD requirements.txt /app/
RUN pip3 install -r requirements.txt
ADD . /app/
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "5000"]
