Interesting -- possibly something we need to run at image build-time.

Here's some deets about what the impact might be (for further exploration):

$ docker run -it --rm --name test php:7-alpine sh
/ # pecl channel-update pecl.php.net
Updating channel "pecl.php.net"

@tianon I'm experiencing similar issue:

Updating channel "pear.php.net"
Channel "pear.php.net" is up to date
Updating channel "pecl.php.net"
Update of Channel "pecl.php.net" succeeded
Could not download from "http://pecl.php.net/get/apcu-5.1.11.tgz", cannot download "pecl/apcu" (File http://pecl.php.net:80/get/apcu-5.1.11.tgz not valid (received: HTTP/1.1 503 Service Unavailable
))
Error: cannot download "pecl/apcu"
Download failed
install failed

It looks that "Service Unavailable" but I'm able to download "http://pecl.php.net:80/get/apcu-5.1.11.tgz" the file manually.

[tianon]

@torinaki that sounds like an environmental, firewall, or upstream service issue, not something related to this image

I'd recommend trying the Docker Community Forums, the Docker Community Slack, or Stack Overflow for help determining the root cause of that issue.

[Lewiscowles1986]

I don't know if docker is failing somewhere silently or if there is some caching but I just had to re-run

pecl update-channels; rm -rf /tmp/pear ~/.pearrc

It's in the dockerfile. I have no idea why pulling php:7.2 is not running that line, but it's not. As a result trying to get xdebug to build leads to an error.

Need a PHP version >= 5.5.0 and < 7.2.0 (found 7.2.7)

[wglambert]

Strange, it works here without needing another pecl update-channels

Libraries have been installed in:
/tmp/pear/temp/pear-build-defaultuserU9FKQQ/xdebug-2.6.0/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the `LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the `LD_RUN_PATH' environment variable
  during linking
• use the `-Wl,--rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

Don't forget to run 'make test'.

| Documentation is available online as well: |
| - A list of all settings: http://xdebug.org/docs-settings.php |

| - Remote debugging: http://xdebug.org/docs-debugger.php |
| |
| |
| NOTE: Please disregard the message |
| You should add "extension=xdebug.so" to php.ini |

| Xdebug. |

Where are you running that? Mine was in Travis-CI using matrix builds to make Docker images.

https://api.travis-ci.org/v3/job/403109444/log.txt

[tianon]

This line is definitely getting run, but it is possible that the protocols have been updated again since the last time the image was built.

If there's something environmental causing this, then there's even less chance there's anything we can really do here.

Looking at the build log you posted (which is much easier to read at https://travis-ci.org/CODESIGN2/docker-php/jobs/403109444), I don't see any errors related to PECL -- in fact, it appears to be failing to install mcrypt?

I believe you've got an issue where you define ARG PHP_VERSION before you FROM php:XXX, which then includes ENV PHP_VERSION (which overwrites your build arg with 7.2.7), and thus when you do ENV PHP_VERSION ${PHP_VERSION} later, you're not getting your build arg, but instead are getting the environment variable from the base image, which screws up your if statements that compare against PHP_VERSION expecting just 7.2 (and getting 7.2.7 instead).
