lstate error: no such file or directory while building Docker from a custom image with Docker build command
I have create a custom image for lamp stack with following files
apps.conf Dockerfile entrypoint.sh start.sh supervisord.conf
Dockerfile was create with ENV, RUN, ADD and CMD command.
Each application installed successfully, but stuck it at ADD command and check the given path which is correct.
ADD /home/ktpl/nayan/MyLamp/supervisord.conf /etc/supervisor/supervisord.conf ADD /home/ktpl/nayan/MyLamp/apps.conf /etc/supervisor/conf.d/apps.conf ADD /home/ktpl/nayan/MyLamp/entrypoint.sh /entrypoint.sh ADD /home/ktpl/nayan/MyLamp/start.sh /start.sh
Process is stuck at Add command.:
lstat home/ktpl/nayan/lamp/supervisord.conf: no such file or directory

Docker builds always work relative to the context – i.e. the directory you pass in the
docker build command. You cannot use absolute paths in ADD, you should be specifying the source file relative to the build context.
For local files you should use COPY instead of ADD too, so your Dockerfile becomes:
COPY ./supervisord.conf /etc/supervisor/supervisord.conf #etc.
And then you build it from your MyLamp directory with
docker build -t my-tag .
ADD can be used to copy local files to image while building.
Couple of things:
- You are building an image using current directory
- In your case,
/home/ktpl/nayan/lampis the valid directory
- Not sure if you have a directory
/home/ktpl/nayan/MyLampexists and files present in there.
As per the documentation of docker
The path must be inside the context of the build; you cannot ADD ../something /something, because the first step of a docker build is to send the context directory (and subdirectories) to the docker daemon.
If your files are in the same directory as you build image, then you may use below statements in
ADD ./supervisord.conf /etc/supervisor/supervisord.conf ADD ./apps.conf /etc/supervisor/conf.d/apps.conf ADD ./entrypoint.sh /entrypoint.sh ADD ./start.sh /start.sh
Of course, like it was mentioned in the other answer,
COPY can also be used.
FROM busybox ADD ./test.txt /test.txt CMD ls /
You can building image and running it shows file being added in the below image.
If all the files and directories present and still you see this problem, then check
.dockerignore has entry for the same.
