How i can connect to pdftk from other container ?

When i try add to Dockerfile pdftk 

ENTRYPOINT ["/bin/bash"]

still have 

pdftk_1_115fe12f025a exited with code 0

If i understand i need run in this container some daemon - how to setup it to I can connect from other container to this and use pdftk app ?

UPDATE 2

Ok i found way to install pdftk in ubuntu 18.04 container 

RUN apt-get -y install libbcprov-java libcommons-lang3-java default-jre-headless


RUN cd /tmp
RUN wget http://fr.archive.ubuntu.com/ubuntu/pool/universe/p/pdftk-java/pdftk-java_3.0.2-2_all.deb
RUN dpkg -i pdftk-java_3.0.2-2_all.deb

  • It doesn't look like pdftk is a daemon -- it's not a server, it's a single-shot linux tool that you invoke when you need it. It runs, converts files, then exits. So, you can't use it this way. – Software Engineer May 31 '19 at 09:54
  • So how connect it ? eailer i use $cmd = 'pdftk "'.$file.'" multistamp "'.$watermarkFile.'" output '.$outFile; - in php container , but in 18.04 pdfth have problems to start – Developer May 31 '19 at 09:57
  • You can't. Not from where you are. You'd have to do Docker-in-Docker to use a docker container from within a container, which means having docker installed in the container, and sharing the docker-socket. You're better off just using pdftk directly, without it being in a container, and working through the problems you mentioned. – Software Engineer May 31 '19 at 10:01
