# Talos nodes as containers, the L2 half of the e2e substrate experiment.
#
# Sits beside hack/e2e-prepare-cluster.bats' QEMU guests rather than replacing
# them. Addressing, CPU and memory deliberately mirror that file so everything
# downstream -- the MetalLB 192.168.123.200-250 pool, hack/e2e-post-install-prep.sh,
# the chainsaw suites -- is unchanged between the two lanes.
#
# NOT `talosctl cluster create docker`: that wrapper forces a single control
# plane (it has --workers but no --controlplanes), has no --disks, and hides the
# container spec. Compose keeps three control planes, as today.
#
# The contract below comes from siderolabs/talos
# pkg/provision/providers/docker/node.go: PLATFORM/TALOSSKU/USERDATA, privileged,
# seccomp:unconfined, read_only, and the tmpfs + volume layout. Two mounts are
# NOT part of that contract and are mandatory anyway -- see the per-mount notes.

# The two host binds every node repeats below, and why each is mandatory:
#
#   /dev:/dev       Docker gives a privileged container its own 64 MB tmpfs /dev,
#                   seeded ONCE at creation. /dev/kvm works because it exists at
#                   start, but ZFS zvols created later never appear, and
#                   linstor-csi then fails ControllerPublishVolume with "could
#                   not determine device path". Binding the host devtmpfs fixes
#                   it, and is why `talosctl cluster create docker` can never
#                   support LINSTOR.
#
#   /run/udev       The LINSTOR satellite hostPath-mounts it. In a container /run
#                   is tmpfs with no udev, so the pod hangs Init:0/1 on
#                   "hostPath type check failed: /run/udev is not a directory".
#
# Written out per service rather than shared through a YAML anchor: compose
# merges mappings but not sequences, so an anchored list nests instead of
# flattening and is rejected as "volumes.0 must be a string".
