Cannot copy file from host (Dockerfile COPY)

Description

Running this:

❯ CGO_ENABLED=0 \
  GOOS=linux \
  GOARCH=amd64 \
  go build -v -a \
  -installsuffix cgo \
  -trimpath \
  -o /tmp/lima/sammi-api \
  ./main.go && \
lima nerdctl --insecure-registry=true compose --file=docker-compose.local.yml up --build

I got this error from nerdctl compose command:

COPY /tmp/lima/sammi-api /usr/local/bin/sammi-api

You can't specify an abstract path in Dockerfile COPY.
The path has to be a relative path inside the build context dir (defaults to the current dir).

Yep, that was it, 👍
