docker executable file not found in PATH

Question

I have a docker image which installs grunt, but when I try to run it, I get an error:

Error response from daemon: Cannot start container foo_1: \
    exec: "grunt serve": executable file not found in $PATH

grunt is available when I try to execute bash in interactive mode

What am I doing wrong?

Here’s my dockerfile

# https://registry.hub.docker.com/u/dockerfile/nodejs/ (builds on ubuntu:14.04)
FROM dockerfile/nodejs
MAINTAINER My Name, me@email.com
ENV HOME /home/web
WORKDIR /home/web/site
RUN useradd web -d /home/web -s /bin/bash -m
RUN npm install -g grunt-cli
RUN npm install -g bower
RUN chown -R web:web /home/web
USER web
RUN git clone https://github.com/repo/site /home/web/site
RUN npm install
RUN bower install --config.interactive=false --allow-root
ENV NODE_ENV development
# Port 9000 for server
# Port 35729 for livereload
EXPOSE 9000 35729
CMD ["grunt"]

Answer 1

Try to build the docker using CMD[“grunt”]

When you build docker using grunt it uses another shell or without a shell to execute the command where $PATH might not be set.

If you specify your command as a regular string (e.g. CMD grunt) then the string after CMD will be executed with /bin/sh -c.

Answer 2

Check your arguments that you've passed. This error is produced sometimes when arguments are out of order.

Answer 3

Try to run it with the following command:

docker run -v $(pwd):/src -it <container_name>

Answer 4

This error can occur when your executable file do not have the execute permission. 

chmod +x docker-entrypoint.sh

This might help.

Answer 5

Add "#!/bin/bash" to the top of your entrypoint file didn't help.

ENTRYPOINT [ "bash", "entrypoint.sh" ]

Answer 6

file not found in $PATH

What's the solution??

build image with --no-cache

Answer 7

try to build the image with --no-cache.

I replaced the docker command from CMD /bin/bash with "jva","-jar","name-of-jar" which gave error. and after that I corrected "jva" with "java" but it was not taking the corrected form and was getting this error continously.

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \".\": executable file not found in $PATH": unknown.

Then I restarted docker but no-luck, then I try the above --no-cache...which solved the problem.
