• How can start a process and stop the process if "error" string appear in the console output strings in one line commands set

  25 janvier 2018, par Thm Lee

  Now I want one line cmd commands set which start a process and monitor the consol output strings stream. And so if error message appear in the process’s console output, then could stop the process immediately.

  For example, I tried below commends sets, but failed. It seems find command didn’t get any strings streams in which search key word "error"

  ffmpeg "endcoding process options set" | find "error" && exit

  or,

  ffmpeg "endcoding process options set" 2>&1 find "error" && exit

  Is there any solutions about this ?

  Thanks in advance

• OCI runtime exec failed : exec failed : (...) executable file not found in $PATH" : unknown

  12 octobre 2024, par Uğur Kaya

  I have dockerized an app which has ffmpeg installed in it via libav-tools. The app launches without problem, yet the problem occured when fluent-ffmpeg npm module tried to execute ffmpeg command, which was not found. When I wanted to check the version of the ffmpeg and the linux distro set up in the image, I used sudo docker exec -it c44f29d30753 "lsb_release -a" command, but it gave the following error : OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"lsb_release -a\": executable file not found in $PATH": unknown

  



  Then I realized that it gives me the same error with all the commands that I try to run inside the image or the container.

  



  OCI runtime exec failed: exec failed: container_linux.go:296: starting container process caused "exec: \"ffmpeg -a\": executable file not found in $PATH": unknown


  



  This is my Dockerfile :

  



  FROM ubuntu:xenial
FROM node
RUN apt-get -y update
RUN apt-get --yes install libav-tools
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app
RUN npm install
COPY . /usr/src/app
RUN npm run build
ENV NODE_ENV production
EXPOSE 8000
CMD ["npm", "run", "start:prod"]


  



  I would kindly ask for your help. Thank you very much !

  Can anyone tell me what I am doing wrong, since this command seems fairly simple to me ?
