This is the Dockerfile I created for testing purposes.

FROM ubuntu:latest MAINTAINER Kapil Gupta "[email protected]" RUN apt-get update RUN apt-get install -y wget RUN apt-get install -y build-essential tcl8.5 RUN apt-get install -y git EXPOSE 9999 ENTRYPOINT ["myGit"] WORKDIR /home 

I ran this command for installing the image :

docker build -t mygit .

Output of docker images :

REPOSITORY TAG IMAGE ID CREATED SIZE mygit latest 1474c446365f 39 minutes ago 414.5 MB redis latest dc2bd412c10c 7 weeks ago 438.8 MB ubuntu latest c73a085dc378 9 weeks ago 127.1 MB 

Ouput of docker run -i -t mygit:latest :

docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"myGit\\\": executable file not found in $PATH\"\n". 

I dont understand what the error means and how to correct it. Please explain the error in your answer too.
