bind options are incompatible with type image

Error message

bind options are incompatible with type image

What it means

Raised by handleImageToMount when a mount of type 'image' also includes a 'bind:' options block. Bind options like propagation apply only to host-path bind mounts, so the converter fails fast on the incompatible combination.

Solutions

Remove the 'bind:' block from the image mount entry.
If a host-path mount was intended, use type: bind with a filesystem path as source instead of an image reference.

Example fix

# before
volumes:
  - type: image
    source: alpine:latest
    target: /mnt/img
    bind:
      propagation: rprivate
# after
volumes:
  - type: image
    source: alpine:latest
    target: /mnt/img

When it happens

Trigger: 'docker stack deploy' with a service volume entry having type: image plus bind: options (e.g. bind: {propagation: rprivate}).

Common situations: Copying a bind-mount entry as a template for an image mount and only changing type and source; YAML anchors merging bind defaults into every mount entry.
