Hello,
My localhost is a aarch64-darwin, and I’m trying to build a docker image for aarch64-linux on a aarch64-linux host.
It seems like that I can’t get nix to try to build with the remote host, it would fail with a “hostPlatform mismatch” error, and not an “unable to connect to …” one.
PS: SSH works on a port different from 22 for this remote host. I have not found a way to specify this. Maybe this is related ?
Expected output
My flake outputs runner, which is a derivation that produces a docker image.
Actual output
When I try to build it. I get the following error message:
error: Package ‘shadow-4.14.2’ in /nix/store/h947mznq84fnw1igj3jgyisswqfma0hi-source/pkgs/os-specific/linux/shadow/default.nix:92 is not available on the requested hostPlatform:
hostPlatform.config = "aarch64-apple-darwin"
package.meta.platforms = [
"aarch64-linux"
... elided
However, I do have a remote builder set up.
I have tried…
-
nix build -j0 .#runner -vvvvvvvvv 2>&1 | grep 'decline', but no word ‘decline’ has been found. Note that I used the-j0option to disable local build, but it still fails with the “hostPlatform mismatch” error. -
nix store ping 'ssh://ubuntu@oracle'works for both my user and root on my local machine (aarch64-darwin).
My configuration
I have used this guide to set up my environment. The configuration is generated by the nix-darwin configuration here.
Here’s are some relevant configuration files:
/etc/nix/machines:
ssh://leana@carbon x86_64-linux /Users/leana/.ssh/id_ed25519 1 1 nixos-test,benchmark,big-parallel,kvm - -
ssh://ubuntu@oracle aarch64-linux /Users/leana/.ssh/id_ed25519 1 4 nixos-test,benchmark,big-parallel,kvm - -
