How to install SWOOLE in a Dockerfile for Laravel8/PHP8 project?

I'll build a Laravel 8 app. The PHP language level is PHP8. How can I integrate Swoole in my Dockerfile?

Actually I try it this way:

RUN pecl channel-update https://pecl.php.net/channel.xml \
    && pecl install swoole

But if I build the Dockerfile, it always runs into this error:

------
 > [11/19] RUN pecl channel-update https://pecl.php.net/channel.xml  && pecl install swoole:
#14 0.283 /bin/sh: 1: pecl: not found
------
failed to solve: rpc error: code = Unknown desc = executor failed running [/bin/sh -c pecl channel-update https://pecl.php.net/channel.xml  && pecl install swoole]: exit code: 127

Does anyone has an idea? If you need more information about it, please let me know.

Regards, Manny
