error with apk-tools 3 when installing on php-fpm Alpine

[albgau]

Describe the bug
When I try to install the apm-agent on latest PHP Alpine images (php:8.4.16-fpm-alpine or php:8.4.15-fpm-alpine), I get the following error:
ERROR: apm-agent-php.apk: v2 package format error
They seems to use now apk-tools 3

apk -v apk-tools 3.0.3-r1, compiled for x86_64.

To Reproduce
Steps to reproduce the behavior:

1. get the image
   docker run --rm -it --user root docker php:8.4.16-fpm-alpine sh

2. Download on apm-agent
   curl -sSLf https://github.com/elastic/apm-agent-php/releases/download/v1.15.1/apm-agent-php_1.15.1_x86_64.apk -o apm-agent-php.apk

3. and try to install
   apk add --allow-untrusted apm-agent-php.apk

4. Finally what i get

ERROR: apm-agent-php.apk: v2 package format error

Expected behavior
On previous container php8.4, I got this message ater installing and it work

OK: 70 MiB in 55 packages`

Can you help me fix this? I'm afraid that future PHP-FPM-Alpine image updates will use newer versions of apk-tools v3, thanks.

If you pin your docker image version to 8.4.16-fpm-alpine3.22 you will have apk v2 until they release an apk v3 format.

docker > apk --version
apk-tools 2.14.9, compiled for x86_64.

Thank you, indeed setting the version to 3.22 works better, we're now safe until the end of support in 2027
