This is my Dockerfile
FROM php:8.1-fpm-alpine3.15
RUN apk update; \
apk upgrade;
RUN apk add libzip-dev
RUN docker-php-ext-install zip
RUN apk add --no-cache libpng libpng-dev && docker-php-ext-install gd && apk del libpng-dev
RUN docker-php-ext-install mysqli pdo pdo_mysql
RUN apk add --no-cache pcre-dev $PHPIZE_DEPS && pecl install redis && docker-php-ext-enable redis.so
I receive back this error during building process
No releases available for package "pecl.php.net/redis"
Check out this github issue: https://github.com/laradock/laradock/issues/1661 where someone had a similar issue in a different case. There are a couple of possible workarounds there.
Boils down to your connection possibly not being able to retrieve the package to you needing to do a couple of extra steps such as updating the channels before you can search for/install redis.
