File not found in Docker image

Question

while i'm not really into Docker i'm struggling with an issue of a not found file. I've added a ls command to show if the file is really there. and sometimes it is, and sometimes it isn't, but always the 'file is missing' error occurs.

I'm running Docker Desktop Community V 2.0.0.3 (31259) on Win10-2004

It went wrong when a library is build:

Dockerfile:

ADD ./build_opus.sh /usr/local/sbin/

#added for debugging
RUN cd /usr/local/sbin && ls

RUN IFS=" " &&
for arch in $TARGET_ARCHS;
do
./build_opus.sh ${arch};
done

ouput:

---> Using cache 
---> 4ddfdc31b266 Step 28/40 : ADD ./build_opus.sh /usr/local/sbin/ 
---> Using cache ---> e4c4ac7fea69 
Step 29/40 : RUN cd /usr/local/sbin && ls 
---> Using cache 
---> 6fda1595d295 Step 30/40 : RUN IFS=" " && for arch in $TARGET_ARCHS; do .usr/local/sbin/build_opus.sh ${arch}; done 
---> Running in 2fcf560d0dbc 
/bin/sh: 1: .usr/local/sbin/build_opus.sh: not found 
/bin/sh: 1: .usr/local/sbin/build_opus.sh: not found 
/bin/sh: 1: .usr/local/sbin/build_opus.sh: not found 
/bin/sh: 1: .usr/local/sbin/build_opus.sh: not found 
The command '/bin/sh -c IFS=" " && for arch in $TARGET_ARCHS; do .usr/local/sbin/build_opus.sh ${arch}; done' returned a non-zero code: 127

Does anyone have an idea?

/usr/ instead of .usr/? Or even just ./build_opus.sh, since you'd cd /usr/local/sbin to it already. — Caramiriel

Hi, thanks for the response. apologize, it should be ./build_opus.sh, it's a left over of my tryings to get it working. modified the script in the question — impeeNL

Can we see the full Dockerfile, and the error from running that dockerfile (you mention above the path shown is wrong)? — SiHa

Hi all, thanks for the response, i've added the full docker file. — impeeNL

You are confusing WORKDIR with cd. In docker, there is a concept called WORKDIR, which acts like cd. It changes the directory location from thereafter to all upcoming instructions. Using cd will only change the directory in that particular layer when instruction comes to the next layer the directory location will be reverted back to WORKDIR.

Hence in order to properly run you either need to use Absolute path of the script or use WORKDIR to change and then run the script.

Using Absolute Path:

RUN IFS=" " &&
for arch in $TARGET_ARCHS;
do
/usr/local/sbin/build_opus.sh ${arch};
done

Using 'WORKDIR':

WORKDIR /usr/local/sbin/
RUN IFS=" " &&
for arch in $TARGET_ARCHS;
do
./build_opus.sh ${arch};
done

Hi Thanks for the answer, unfortunately it didn't work out. I added the WORKDIR and added a ls command to the RUN command, the file is present, but still the file is not excecuted ``` Step 30/40 : RUN ls && IFS=" " && for arch in $TARGET_ARCHS; do ./build_opus.sh ${arch}; done ---> Running in e208955e37f4 build_opus.sh unminimize /bin/sh: 1: ./build_opus.sh: not found .....exited with code 127```

Apologize guys, It's an error INSIDE the build_opus.sh file. I've added a thon of 'echo' commands and got some steps further. Thanks for all the help!

Upvotining and accepting answers are better ways of saying thanks..upvote the answer if you find it useful and accept it if it solved the error.

@impeeNL Hi, I think I'm having the same issue you had with build_opus.sh creating docker container from Windows of pjsip. Can you help me?
