Needs command that do not capture content ?

[YanzhaoLi]

When we copy multiple files which needs sudo capability, scp doesn't work. In this case, we could execute sudo command to copy these files to /tmp and then execute scp. Thus, we need dummy command that does not capture content.

# To Copy multiple root-owned files
# Since we have no root user, we couldn't scp root-owned files such as container logs.
# Fortunately, we have sudo privilege, we make a trick to sudo copy these logs into where we can scp
CAPTURE /bin/bash -c 'mkdir -p /tmp/containers; for file in $(ls /var/log/containers/); do sudo cat /var/log/containers/$file > /tmp/containers/$file; done'
COPY /tmp/containers
CAPTURE /usr/bin/rm -rf /tmp/containers

In this case, the two CAPTURE command would generate two useless files. How about add a RUN command which only run command instead of generating files

@YanzhaoLi thanks for this issue.
I am looking into improving how commands are executed.
This is a great case to help with that. Looking into a solution Soon.
