apk add --root fails
apk add --initdb --root /tmp/tmpdir alpine-base
however that returns
ERROR: Missing packages: alpine-base
turns out that apk tools from at least 1.10.1 onward need to have the keys and repository information in the root:
mkidr -p /tmp/tmpdir/etc cp -a /etc/apk /tmp/tmpdir/etc apk add --initdb --root /tmp/tmpdir alpine-base
I would have assumed the initdb would have copied the repository information to the tmp root, or something.
