What does “copy . .” mean? Thank you.
COPYinstruction copies new files or directories from
<src>and adds them to the filesystem of the container at the path
<dest>is an absolute path, or a path relative to
It means the same thing yes, the dot is “where i am now”
So it will copy everything from the same place as the dockerfile, to “where i am now” in the container.
The “where i am now” in the image/container is defined by https://docs.docker.com/engine/reference/builder/#workdir
So if you set:
COPY . .
It will copy everything in the current folder, to /tmp
Hope that makes sense
