Allow Dockerfile to ignore itself #7969
Description
I have the smallest possible Dockerfile that I use to build our website:
FROM peopleperhour/supertasker
ADD . /var/www/
When I run the resulting container (which is a webserver) I get a Dockerfile at /var/www - not a problem but not the cleanest.
I thought I could solve this issue by adding a .dockerignore file (released in version 1.1):
$ cat .dockerignore
Dockerfile
However, if I do this, when I build I get a error:
$docker build -t="peopleperhour/supertasker:bd40102" .
2014/09/10 11:37:33 Dockerfile was excluded by .dockerignore pattern 'Dockerfile'
This is the Docker go code that gives the error: 27cca4c70cc7f0cccfda
It would be nice if Docker could use .dockerignore to prevent adding the Dockerfile to the build context. Or maybe this is a workaround?
