Dockerfile is not working properly when using WORKDIR command?

Question

Here's my Dockerfile that I want to use for one of my web-api using python fastapi, but whenever I try to built it, I am getting the below given error.

FROM tiangolo/uvicorn-gunicorn:python3.8

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get dist-upgrade -y && \
    apt-get autoremove -y && \
    apt-get clean && \
    apt-get autoclean && \
    apt-get install -y gcc make apt-transport-https ca-certificates build-essential

RUN apt-get install -y curl autoconf automake libtool pkg-config git
RUN git clone https://github.com/openvenues/libpostal

WORKDIR /libpostal
RUN ./bootstrap.sh
RUN libpostal/configure --datadir=/opt
RUN libpostal/make -j $(nproc)
RUN libpostal/make install && ldconfig



ENV PORT 8000
ENV APP_MODULE app.parser:app
ENV LOG_LEVEL debug
ENV WEB_CONCURRENCY 2

COPY ./requirements/base.txt ./requirements/base.txt
RUN pip install --no-cache-dir -r requirements/base.txt


COPY ./app /app/app

Whenever I run this I am getting this below error,

Please tell me what am I doing wrong in the Dockerfile?

Answer 1

The default WORKDIR for your base image tiangolo/uvicorn-gunicorn:python3.8 is /app. I believe this is the Dockerfile for the base. When you cloned the repo, you were actually running it in /app.

You can explicitly set WORKDIR / or specify WORKDIR /app/libpostal to successfully run the bootstrap script.

You should also adjust your paths in the RUN commands after cloning since they should be relative. Here are the changes I suggest:

Option 1

# this command is run in the /app folder, a default set in the base image
RUN git clone https://github.com/openvenues/libpostal

WORKDIR /app/libpostal
RUN ./bootstrap.sh
RUN ./configure --datadir=/opt
RUN make -j $(nproc)
RUN make install && ldconfig

Option 2

# explicitly set working directory in root
WORKDIR /
RUN git clone https://github.com/openvenues/libpostal

WORKDIR /libpostal
RUN ./bootstrap.sh
RUN ./configure --datadir=/opt
RUN make -j $(nproc)
RUN make install && ldconfig
