Build Docker image for PHP Web application - ADD failed

Question

I have created a dockerfile with the base image devopsedu/webapp for PHP web application.

FROM devopsedu/webapp
ADD proj /var/www/html
RUN rm /var/www/html/index.html
CMD apachectl -D FOREGROUND

When I tried to build the docker image using dockerfile, it failed on step 2 indicated that "no such file or directory" error message.

edureka@server:$ docker build -t devopsedu/webapp:dockerfile .
Sending build context to Docker daemon  2.048kB
Step 1/4 : FROM devopsedu/webapp
 ---> 0ef91240e173
Step 2/4 : ADD proj /var/www/html
ADD failed: stat /var/lib/docker/tmp/docker-builder032612005/proj: no such file or directory

Paths in your Dockerfile are not absolute paths on your filesystem, but relative to the build-context. Check if that is within the build context.

Thank you Sirajul

Yes, I have changed it to the absolute paths on my filesystem and it is working now.

FROM devopsedu/webapp
ADD website /var/www/html
RUN rm /var/www/html/index.html
CMD apachectl -D FOREGROUND

Hey @Animesh, this was the error

edureka@server:$ docker build -t devopsedu/webapp:dockerfile .
Sending build context to Docker daemon  2.048kB
Step 1/4 : FROM devopsedu/webapp
 ---> 0ef91240e173
Step 2/4 : ADD proj /var/www/html
ADD failed: stat /var/lib/docker/tmp/docker-builder032612005/proj: no such file or directory

I changed the path to an absolute path. The absolute path of your resources refers to an absolute path within the build context, not an absolute path on the host. 

So all the resources must be copied into the directory where you run the docker build and then provide the path of those resources within your Dockerfiles before building the image. (This refers to the location where you run your Dockerfile).
 

This resolved the error for me.
