Support multiple php version in one workspace

[rainbowdrg]

Hi,

I need to have one workspace to support multiple versions of php for my project that integrate with many different php versions of services

I know I can create many workspaces with different php version but I wish to make it all in one to save resources. And also can run composer install without switch between workspace containers

I have tried add the code below at the end of workspace/Dockerfile and it work previously.

RUN apt-get install -y --allow-downgrades --allow-remove-essential \
        --allow-change-held-packages \
        php8.0-cli \
        php8.0-common \
        php8.0-curl \
        php8.0-intl \
        php8.0-xml \
        php8.0-mbstring \
        php8.0-mysql \
        php8.0-pgsql \
        php8.0-sqlite \
        php8.0-sqlite3 \
        php8.0-zip \
        php8.0-bcmath \
        php8.0-memcached \
        php8.0-gd \
        php8.0-dev \
    && apt-get clean

But when I try rebuild workspace today, I got error message: Unable to locate package php8.0-cli. My workspace main version using latest php 8.1

Please advice me any way to make one workspace support multiple php versions.

Thanks.

How do you do in the development environment not dockering to switch php versions?
