Build docker container from Rust workspace with multiple projects

I have a Rust workspace project with multiple sub projects. I would like to build these inside of docker. I cannot use cargo build at root because some of these projects are wasm projects and use Trunk to build.
The core issue I'm finding is that when I do WORKDIR and move to a new directory, the parent directories are no longer accessible. For example the dockerfile shown below copies my entire workspace into /usr/src/rustyindie-web and then later on it switches WORKDIR to /usr/src/rustyindie-web/web and runs its Trunk build. This build fails because since the project is a workspace the target folder is in the parent /usr/src/rustyindie-web folder, which seems inaccessible from /usr/src/rustyindie-web/web. And so I get this error

FROM rustlang/rust:nightly-alpine as builder
WORKDIR /usr/src/rustyindie-web
COPY . .
RUN apk add musl-dev
RUN rustup target add wasm32-unknown-unknown
RUN cargo install wasm-bindgen-cli
RUN cargo install trunk
# first setup web build
WORKDIR /usr/src/rustyindie-web/web
RUN cargo install wasm-bindgen-cli
RUN cargo install trunk
RUN trunk build --release

Could you replace the second WORKDIR with RUN cd?
