Is there a way to change the CWD of the

docker_image

rule? I have a use case of running Docker on a git submodule but I'm trying to avoid modifying the code in that submodule. So my setup is in the parent directory of the submodule and looks like

docker_image(
    name="prom-aggregation-gateway",
    source="feat-configurable-gauge-agg/cmd/prom-aggregation-gateway/Dockerfile",
    dependencies=[
        ":submodule"
    ]
)

files(
    name = "submodule",
    sources = ["./feat-configurable-gauge-agg/**"]
)

Unfortunately, the Docker build isn't able to find

/prom-aggregation-gateway

FROM alpine:3.10
COPY prom-aggregation-gateway /
ENTRYPOINT ["/prom-aggregation-gateway"]
