I don’t see any problems with your copy command. Verify that etc actually exists in your working directory: ‘ls -la $(pwd) src/‘ before the docker build command
There are two approach:
1) Put al the files in the same directory where the you kept the Dockerfile. And be in that persent directory, then execute the docker run command. You cannot pass any relative path, all files should be in same folder.
2) Put all the required files except the Dockerfile in a diffrent path. Use the "-f- /PATH" option in docker run command from the current directory where your Dockerfile is present. Or you can give the full path of the docker file.
docker build -t docker.io/rohitbasu77/php:7.2-apache -f- /sys/fs/cgroup < Dockerfile
OR
docker build -t docker.io/rohitbasu77/php:7.2-apache -f- /sys/fs/cgroup </root/GIT/otrs5/Dockerfile
Now the root pathe where the files are kept is /sys/fs/cgroup/. you can copy everything from here. put all your folders and file under this root path.
/root/GIT/otrs5/Dockerfile:
FROM php:7.2-apache
ADD . /tmp/fs/cgroup/. #Every thing from your local /sys/fs/cgroup/* is copied to a new folder /tmp/fs/cgroup (if not present will be created)
src/relative path you set in theCOPYcommand. Since you wrote a relative path, that path is relative to the location of the Dockerfile. Since you are building against.(your current working directory, which appears to be/mnt/sda1/var/lib/docker/tmp/docker-builder006125699), you should have asrc/dir, if not that error will occur.
