Podman COPY file

[RogerioLSantos]

Hi Guys, a question about COPY command inside Containerfile

is it mandatory that the file I want to copy be in the same folder as the Containerfile/Dockerfile file?

I ask that because in my Containerfile I put the instruction COPY
/home/user/Downloads/file.zip /opt/, however when I run the command podman build, I receive an error message: no such file or directory , however, the file exists in the folder /home/user/Downloads/

Hi RogerioLSantos,

Where is your dockerfile exists?

the folder /home/user/Downloads/file.zip should be into the same context as of dockerfile. Please go through the github issue which was raised for the same.

Hi vikassharma, my /home/user/Downloads/file.zip is in a different context

I thought that COPY would read any folder in the host.

In this structure works

However, I was trying to use a folder outside of this context, because I thought that COPY has visibility of all folders in the host.

You can't COPY a zip! You need ADD! And add does not work with zip, but with .tar

And you need all of it in the current dir where you execute the build command.
