Cannot build gce images #146

Open favila opened 9 years ago

favila commented 9 years ago

Using https://github.com/cloudius-systems/capstan-example-clojure as an example:

$ capstan build -p gce -v

Looking into this a bit more, the .capstan/repository/cloudius/osv-openjdk/openjdk.gce file contains the text string gs://osv/v0.22/osv-openjdk.gce.tar.gz instead of a binary disk image. I'm not sure what this means.

I'm having the same issue :(

The downloaded gce image file from capstan repo is not a normal image on purpose.

It is an address for an image on google cloud storage, e.g., to same the time to upload load image to gce.

gs://osv/v0.22/osv-openjdk.gce.tar.gz

Francis, capstan build with gce does not work. Can you try capstan build with qemu?

Updated capstan using the prebuilt binary.

Qemu building works (and did before IIRC).

Building for gce errors out. It looks like some tool (qemu?) is confused that the image contains only a url (which is why I mentioned it earlier). I understand that this is how google compute images work, but the image itself needs to be built somewhere locally and it doesn't look like it is. Further, the capstan-example-clojure.gce image contains the url of the openjdk image (gs://osv/v0.23/osv-openjdk.gce.tar.gz) which can't be right.

New output below:

$ capstan -v

yeah, i'm not quite sure how that works w/ the URL to the base image. It feels like it was downloaded but the final image doesn't get built.
