invalid reference format when building a docker file

[former_member754666]

I am new to SAP docker images. I try to test this system for SAP Text-Analysis; https://github.com/SAP-samples/data-intelligence-text-analysis

However, I get this error when I try to build the Dockerfile as follows;

"""

xxxx@xxxx's-MacBookPro docker % docker build -t sap-ta-sample-image .

[+] Building 0.1s (2/2) FINISHED

=> [internal] load build definition from Dockerfile 0.0s

=> => transferring dockerfile: 1.12kB 0.0s

=> [internal] load .dockerignore0.0s

=> => transferring context: 2B0.0s

failed to solve with frontend dockerfile.v0: failed to create LLB definition: failed to parse stage name "§/com.sap.datahub.linuxx86_64/sles:15.0-sap-007": invalid reference format

"""

I tried to use opensuse/leap:15.0 as another base image since it is introduced in the README in the git repository. However it also returned the same error.
Does anyone have any clue on this? Thank you so much for your help in advance! Much appreciated.

"§/com.sap.datahub.linuxx86_64/sles:15.0-sap-007" refers to a pre-shipped Docker Image from SAP Data Intelligence.

If you want to build the Dockerfile locally, you need to adapt a few things:

• Use opensuse leap 15.0
• Install python3, pip and further build tools
• Use UTF-8 locale instead of ASCII

The resulting Dockerfile may look like this:

# FROM §/com.sap.datahub.linuxx86_64/sles:15.0-sap-007
FROM opensuse/leap:15.0

# Install tar, gzip, python3, pip3, gcc and libgthread
RUN zypper --non-interactive update && \
    zypper --non-interactive install --no-recommends --force-resolution \
    python3 python3-pip tar gzip gcc=7 gcc-c++=7 libgthread-2_0-0=2.54.3
RUN python3 -m pip --no-cache install pip --upgrade
RUN python3 -m pip --no-cache install tornado==5.0.2
ENV LANG=C.UTF-8
ENV LC_ALL=C.UTF-8
