Im having trouble understanding how to proceed after puling a docker file from a repo
I have installed docker on ubuntu 20. and pulled from mediagis/nominatim
My goal is to run " docker build -t nominatim . "
as per instructions https://hub.docker.com/r/mediagis/nominatim , but when I do, I get the following error
unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/james/Dockerfile: no such file or directory
I also cant seem to locate the docker file
in /var/lib/docker I have the following folders
{builder containers network plugins swarm trust
buildkit image overlay2 runtimes tmp volumes}
typing ‘docker images’ in the console reveals the image "mediagis/nominatim latest 687be9f4eccb "
Overlay2, which appears to be my driver, contains a multitude of files , none of which seem to correlate to 687be9f4eccb
The only place I have found this is in var/lib/docker/image/overlay2/imagedb/content/sha256 ( is this the docker file ?) if I navigate to this directory and try to run I get the same error message
unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /var/lib/docker/image/overlay2/imagedb/content/sha256/Dockerfile: no such file or directory
Could someone tell me where I am meant to run this build command from ?
