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

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!

This happened to me on windows. Any of these commands will work

On Windows CMD (not switching to bash)

docker exec -it <container-id> /bin/sh

On Windows CMD (after switching to bash)

docker exec -it <container-id> //bin//sh

or

winpty docker exec -it <container-id> //bin//sh

On Git Bash

winpty docker exec -it <container-id> //bin//sh

NB: You might need to run use /bin/bash or /bin/sh, depending on the shell in your container.

The reason is documented in the ReleaseNotes file of Git and it is well explained here - Bash in Git for Windows: Weirdness...

"The cause has to do with trying to ensure that posix paths end up being passed to the git utilities properly. For this reason, Git for Windows includes a modified MSYS layer that affects command arguments."
