I am trying to deploy my docker container on AWS Lambda. However, I use pdf2image package in my code which depends on poppler. To install poppler, I need to insert the following line in the Dockerfile.
RUN apt-get install -y poppler-utils
This is the full view of the dockerfile.
FROM ubuntu:18.04
RUN apt-get update
RUN apt-get install -y poppler-utils
RUN apt-get install python3 -y
RUN apt-get install python3-pip -y
RUN pip3 install --upgrade pip
WORKDIR /
COPY app.py .
COPY requirements.txt .
RUN pip3 install -r requirements.txt
ENTRYPOINT [ "python3", "app.py" ]
However, to deploy on Lambda, I need to use AWS base python image for Lambda. This is my attempt to rewrite the above dockerfile to use the Lambda base image.
FROM public.ecr.aws/lambda/python:3.6
# Cannot run the follow lines: apt-get: command not found
# RUN apt-get update
# RUN apt-get install -y poppler-utils
COPY app.py .
COPY requirements.txt .
RUN pip install -r requirements.txt
CMD ["app.handler"]
Based on the dockerfile above, you can see that the apt-get command cannot be run. Understandable because it is not from ubuntu image like I did earlier. My question is, how can I install the poppler in the Lambda base image?
It uses the yum package manager, so you can do the following instead:
FROM public.ecr.aws/lambda/python:3.6
RUN yum install -y poppler-utils
