Answer 1

I faced the same issue, was working on Windows.

Actual Problem

Running the following command docker container commit --change="CMD ["java","-jar","/tmp/hellotm-0.0.1-snapshort.jar"]" flamboyant_knuth syedwn14/hellotm-0.0.1-snapshort:manual2 from cmd or powershell adds Windows line endings (\r\n called CRLF) .

On running the following command, the docker container is started.

docker run -p 8080:8080 syedwn14/hellotm-0.0.1-snapshort:manual2

Once the docker container has started it tries to execute the bash command.

["java","-jar","/tmp/hellotm-0.0.1-snapshort.jar"]

But instead throws an error

/bin/sh: [java,-jar,/bin/sh/hellotm-0.0.1-snapshort.jar]: not found.

For the bash command to be executed properly we need to convert the line endings of this command to Linux EOL (\n called "LF") .

Easiest Solution that I use:

1. Install Git Bash (it provides a UNIX style command interface).
2. Run the following command from Git Bash docker container commit --change="CMD ["java","-jar","/tmp/hellotm-0.0.1-snapshort.jar"]" flamboyant_knuth syedwn14/hellotm-0.0.1-snapshort:manual2 . This will ensure that the line endings are Linux EOL .

Note: On running docker container exec flamboyant_knuth ls /tmp from Git Bash you will face the following error message.

$ docker container exec elated_fermat ls /tmp
ls: C:/Users/<user_name>/AppData/Local/Temp: No such file or directory

Instead run the command on either cmd or powershell .
