Here's the one I used as of today:

ARG TARGETARCH
ARG TARGETOS
RUN if [ "$TARGETARCH" = "amd64" ] ; then \
    GCLOUD_ARCH="${TARGETOS}-x86_64"; \
    elif [ "$TARGETARCH" = "arm64" ] ; then \
    GCLOUD_ARCH="${TARGETOS}-arm"; \
    fi; \
    export GCLOUD_ARCH; \
    env | grep GCLOUD_ARCH >> /etc/profile.d/gcloud-arch.env
RUN . /etc/profile.d/gcloud-arch.env
RUN curl -sL \
    "https://www.googleapis.com/storage/v1/b/cloud-sdk-release/o?prefix=google-cloud-sdk-5" \
    | jq -r ".items[].selfLink | select ( match (\"${GCLOUD_ARCH}\") )" \
    | grep '.tar.gz' \
    | tail -n1 \
    | curl -sL $(awk '{print $1"?alt=media"}') | tar xzf - -C $SDK_DIR
RUN /usr/local/lib/google-cloud-sdk/install.sh --quiet
RUN echo "export PATH=$SDK_DIR/google-cloud-sdk/bin:$PATH" | tee -a /etc/profile.d/gcloud-sdk.sh
