Apache PredictionIO - Docker run failed

I have been trying http://predictionio.apache.org/install/install-docker/ this tutorial. I have successfully built Docker image however when I try to run docker run i get the Can't open /etc/predictionio/pio-env.sh error.

  1. docker build -t predictionio/pio pio
  2. docker run -ti predictionio/pio

PS: If I comment out the last line CMD ["sh", "/usr/bin/pio_run"] I can build and run docker image successfully. I can open the file too from docker bash.

enter image description here

Just resolved it on my machine.

When you cloned repository on Windows, git converted end of line symbols from Unix-style (\n) to Windows style (\r\n).

You need to open file C:\wherever-you-cloned-pio-repository\predictionio\docker\pio\pio_run and change it back (for e.g. using Visual Studio Code, or Notepad++). Then you need to rebuild the image and it should work.

Also for the future you may want to disable automatic conversion Disable git EOL Conversions

Your output states you are running Windows. Did you use the default command prompt or did you use docker terminal? I had the same error messages in the past on Windows but mysteriously it disappeared after trying the tutorial again. I am not sure what I did different except I might possibly used docker instead of the default command prompt...

Could you also try using docker-compose instead of plain docker commands as described in the tutorial?

Ensure your storage (Postgres, MySQL or ElasticSearch) is running before starting PIO as well.

I think you need to grant permissions to execute this file. add the following line at the end of your Dockerfile

RUN chmod +x pio_run.sh

also, you might need to change CMD to ENTRYPOINT like following:

ENTRYPOINT ["sh","/usr/bin/pio_run.sh"]
