phpdockerfilealpine-linux

Can I skip GLIBCXX check when using an unsupported Alpine distro?

I'm developing a workspace that uses Alpine and Php 7.2 as it's main components. I have a Dockerfile that uses the php:7.2-fpm-alpine distro for that matter, it builds and composes normally when performing docker compose up -d, but when I try to open it in a Remote Container, the following error appears: enter image description here

I browsed the net only to see my problem seems to be very poorly documented, the only relevant instance of my problem is the Visual Studio Code's official Github project that has the following file check-requirements-linux.sh. Obviously I could use another image, but it is imperative for it to be an Alpine distro (so anything that is php:7.2-<ALPINE DISTRO>), so I'd like to know if there is a way to ignore this, either by skipping the script check, or any other way that makes work without worrying about it, something that suddenly closes the Dev Container and makes me unable to open it and program in.

A popular workaround to this problem (that works) is to downgrade the Visual Studio Code version to v.1.8.5, as mentioned in the Github thread, but it is wildly unpractical, and only a temporary solution.

If it helps, this is my current Dockerfile that I'm building (that builds without any problem). Dockerfile

Solution

  • You can skip the requirements check by creating the file /tmp/vscode-skip-server-requirements-check, see the start of the check-requirements-linux.sh script.

    But as the error message tells you the version of alpine you used is not supported by vscode, see https://aka.ms/vscode-remote/linux: vscode requires alpine 3.16+ with musl >= 1.2.3

    The image you use - php:7.2-fpm-alpine3.12 - is based on alpine 3.12 which uses musl 1.1.24.

    So you could skip the check but would then most probably run into other issues afterwards. Instead you should use a base image with a supported alpine version, e.g., php:7.4-fpm-alpine, or if no appropriate image is available on the docker registry build your own from scratch.
