PHP8.0-alpha1: PECL not found

[michaljusiega]

Hello,

I'm trying to use an image for PHP 8.0, but pecl command does not exist:

For example:

...
&& pecl install apcu && docker-php-ext-enable apcu \
...

For PHP 7.4: docker run php:7.4.7-apache-buster pecl

Output:

E:\PROJEKTY\intranet>docker run php:7.4.7-apache-buster pecl
Commands:
build                  Build an Extension From C Source
bundle                 Unpacks a Pecl Package
channel-add            Add a Channel
...

For PHP 8.0-alpha1: docker run php:8.0.0alpha1-apache-buster pecl

Output:

E:\PROJEKTY\intranet>docker run php:8.0.0alpha1-apache-buster pecl
/usr/local/bin/docker-php-entrypoint: 9: exec: pecl: not found

It seems to me that the PHP team did something from the PECL repository but I can't find any information about it.

Okay, I found information for Dockerfile PHP 7.4:

php/7.4/buster/apache/Dockerfile

Line 227 in b6fd2f7

# in PHP 7.4+, the pecl/pear installers are officially deprecated (requiring an explicit "--with-pear") and will be removed in PHP 8+; see also https://github.com/docker-library/php/issues/846#issuecomment-505638494

but there is not that line in Dockerfile PHP 8.0.

Is there any replacement for installing this repository?

See #851

Okey,

so in PHP 8.0 instead

...
&& pecl install apcu && docker-php-ext-enable apcu \
...

should be:

...
&& mkdir -p /usr/src/php/ext/apcu && curl -fsSL https://pecl.php.net/get/apcu | tar xvz -C "/usr/src/php/ext/apcu" --strip 1 && docker-php-ext-install apcu \
...

or use a pickle utility directly

RUN wget https://github.com/FriendsOfPHP/pickle/releases/download/v0.6.0/pickle.phar && mv pickle.phar /usr/local/bin/pickle
pickle install apcu

In my case, both work.

or use a pickle utility directly

In my case I also had to:

RUN chmod +x /usr/local/bin/pickle

In my case I also had to

docker-php-ext-install zip

before being able to use pickle
