Usage of Wgrib2 utility in R operator

[SAPSupport]

Our goal is to convert .GRB files using R script declared in an R Client operator. Is it possible to create a docker file that can be used by the custom R Client operator?

Create and build below dockerfile script:

FROM docker.io/debian:bullseye-slim

ENV DEBUG true
ENV FC=gfortran
ENV CC=gcc

RUN apt-get update && apt-get install -y \
ca-certificates \
curl \
wget \
build-essential \
bzip2 \
tar \
amqp-tools \
openssh-client \
gfortran \
cmake \
--no-install-recommends && rm -r /var/lib/apt/lists/* \
&& wget ftp://ftp.cpc.ncep.noaa.gov/wd51we/wgrib2/wgrib2.tgz -O /tmp/wgrib2.tgz \
&& mkdir -p /usr/local/grib2/ \
&& tar -xf /tmp/wgrib2.tgz -C /tmp/ \
&& rm -r /tmp/wgrib2.tgz \
&& mv /tmp/grib2/ /usr/local/grib2/ \
&& cd /usr/local/grib2/grib2 && make \
&& ln -s /usr/local/grib2/grib2/wgrib2/wgrib2 /usr/local/bin/wgrib2 \
&& apt-get -y autoremove build-essential

VOLUME /srv/
VOLUME /opt/
WORKDIR /opt/
ENTRYPOINT [ "/bin/bash" ]
CMD ["/opt/entrypoint.sh"]

Hi,

We built docker as per above steps and it is successful, however R code is still complaining that its not able to find wgrib2.

• sh: 1: /usr/local/bin/wgrib2: not found

Thanks
