I am trying to achieve a rather simple task, however I have been failing at it for quite a few hours now. I am sure I am missing something simple.
All I am trying to do is to capture the last line of
docker log to a variable in a shell script.
Here is my setup:
FROM python:3.7.2 WORKDIR /workspace RUN pip install jupyterlab EXPOSE 8888 ENTRYPOINT ["jupyter", "lab", "--ip=0.0.0.0", "--allow-root", "--no-browser"]
#!/bin/sh docker build -t ml/jupyterlab . docker rm -f ml-jupyterlab docker run -d -p 8888:8888 -v $(pwd)/src:/workspace --name ml-jupyterlab ml/jupyterlab until [[ "$url_info" =~ "token" ]]; do url_info=$(docker logs ml-jupyterlab --tail 1) sleep 0.1 done echo "$url_info"
Executing the following
$ chmod +x run.sh $ ./run.sh
gets into an infinite loop as
I would really appreciate any help I can get here.
