Unable to install Tesseract 5.0 version on AWS Lambda - amazon-web-services

Question

I want to run Tesseract 4.0 or Tesseract 5.0 on my AWS Lambda function. So I have my docker file like so-
FROM public.ecr.aws/lambda/python:3.8
RUN mkdir app
# Copy function code
COPY / ${LAMBDA_TASK_ROOT}/app
# Install the function's dependencies using file requirements.txt
# from your project folder.
COPY requirements.txt .
RUN pip3 install -r requirements.txt --target ${LAMBDA_TASK_ROOT}
RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
RUN yum -y update
RUN yum -y install tesseract
RUN yum install -y poppler-utils
# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "app.com.emlAndMsgParser.mail_parser_test.getEmail_from_msg" ]
but when i do DockerBuild-"docker build -t qa-lambda ." on my terminal, it says Tesseract 3.0 version is getting installed. When i deploy this built Docker image to AWS Lambda,it also says Tesseract 3.0 is installed.
But I want Tesseract 4.0 or preferably Tesserct 5.0.
I tried changing the "RUN yum -y install tesseract" in my Dockerfile to "RUN yum -y install tesseract 5.0.0-alpha-320-g8dc3" and "RUN yum -y install tesseract -y" or "RUN yum -y install tesseract*".
But all of them are installing Tesseract 3.0.
Please can anyone tell me where I am going wrong?
I am a bit new to Tesseract, so any help is appreciated..thanks!

Having the same problem, I finally created a Dockerfile myself:
FROM public.ecr.aws/lambda/java:11 q
# Prepare dev tools
RUN yum -y update
RUN yum -y install wget libstdc++ autoconf automake libtool autoconf-archive pkg-config gcc gcc-c++ make libjpeg-devel libpng-devel libtiff-devel zlib-devel
RUN yum group install -y "Development Tools"
# Build leptonica
WORKDIR /opt
RUN wget http://www.leptonica.org/source/leptonica-1.82.0.tar.gz
RUN ls -la
RUN tar -zxvf leptonica-1.82.0.tar.gz
WORKDIR ./leptonica-1.82.0
RUN ./configure
RUN make -j
RUN make install
RUN cd .. && rm leptonica-1.82.0.tar.gz
# Build tesseract
RUN wget https://github.com/tesseract-ocr/tesseract/archive/refs/tags/5.2.0.tar.gz
RUN tar -zxvf 5.2.0.tar.gz
WORKDIR ./tesseract-5.2.0
RUN ./autogen.sh
RUN PKG_CONFIG_PATH=/usr/local/lib/pkgconfig LIBLEPT_HEADERSDIR=/usr/local/include ./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/lib
RUN LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make -j
RUN make install
RUN /sbin/ldconfig
RUN cd .. && rm 5.2.0.tar.gz
# Optional: install language packs
RUN wget https://github.com/tesseract-ocr/tessdata/raw/main/deu.traineddata
RUN wget https://github.com/tesseract-ocr/tessdata/raw/main/eng.traineddata
RUN mv *.traineddata /usr/local/share/tessdata
WORKDIR /root
ENTRYPOINT [ "tesseract", "--version" ]
Hope this helps!
