Without Docker the scripts are able to parse the pdf files using tika.

But however when I'm trying with Docker..I get the following error for the tika server not running: with some reading I tried the following - but the error persists.

Can some please help?

I'm attaching the Dockerfile in the end and listing the docker containers that are running -

  1. docker pull apache/tika
  2. docker run -d -p 9998:9998 apache/tika
  3. cat Dockerfile (listing in the end)
  4. docker build -t docker_parser .

  5. docker run docker_parser

  6. docker ps -a

Looks like you haven't specified a link between the containers, so tika-python isn't able to connect to port 9998. You could add Java in the docker_parser container and let it host Tika Server, otherwise you'll need to link the containers.

If you want to use the two images, you can either use the --link option on Docker CLI at run time, or build a network (docker network create) and attach the two containers together (docker network connect). I normally use docker-compose to make these kind of things easier and specify the links there.
