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:18.04RUN apt-get update
RUN apt-get install -y poppler-utilsRUN apt-get install python3 -y
RUN apt-get install python3-pip -y
RUN pip3 install --upgrade pipWORKDIR /COPY app.py .
COPY requirements.txt  .RUN  pip3 install -r requirements.txtENTRYPOINT [ "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-utilsCOPY app.py .
COPY requirements.txt  .RUN pip install -r requirements.txtCMD ["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:3.6RUN yum install -y poppler-utils
