Documentation has commands that include brunch when webpack.js is what is used by a fresh elixir phoenix app (as of v1.4.1).

If you are building with docker then changing the relevant steps in the Dockerfile to this seems to work:

# This step installs all the build tools we'll need
RUN apk update && \
  apk upgrade --no-cache && \
  apk add --update --no-cache \
    nodejs \
    nodejs-npm \
    git \
    build-base && \
  mix local.rebar --force && \
  mix local.hex --force

# This copies our app source code into the build container
COPY . .

RUN mix do deps.get, deps.compile, compile

# This step builds assets for the Phoenix app (if there is one)
# If you aren't building a Phoenix app, pass `--build-arg SKIP_PHOENIX=true`
# This is mostly here for demonstration purposes
RUN if [ ! "$SKIP_PHOENIX" = "true" ]; then \
  cd ${PHOENIX_SUBDIR}/assets && \
  npm install && \
  node node_modules/webpack/bin/webpack.js --mode production && \
  cd .. && \
  mix phx.digest; \
