igbinary | standard php serializer | JSON Processing library

Basically this error means there is no connectivity between the container and the internet but i wasn't able to figure out why this happened.

Thanks to Rwd who did mention this Github Issue in the comment section i noticed that am using an old version of docker, i was running Ubuntu 16.04 .. later i upgraded to 20.04, during the upgrade the docker repository was disabled so i ended up not upgrading docker for quiet a time.

So what i did was simply reinstalling docker :

I removed the old versions

Fixed it, I was being an idiot yesterday night.

Solution A: (In my case): Downgrade back to Docker Desktop version 4.0.0. I was using Intel Images so that's why I had to specify x86_64.

A more better solution would to change all my images be Arm64 and Intel based as well as it being compatible with Ubuntu + Mysql (currently docker Is recommending to use MariaDB for now)

However - seeing that Docker is still relatively unstable and can stop your build process at any moment, I advise anyone to update the Docker for M1 with caution!

The easiest way is using this repo

It's as easy as

First, I don't think you need the frontend/web/php.ini when using Redis cause you will handle everything from Yii, not from php configuration, so I'm just saying that it is useless.

Second, since you're sharing a lot of components between the two applications, you might want to put the common configuration into some common php files and include them in both applications. Example:

Add this to both frontend and backend configs:

Ondřej has removed support for 16.04 just a few days ago:

As of this moment, all the packages for the Ubuntu 16.04 LTS (Xenial) have been removed from the repositories.

This explains how it worked ok for you last week, but isn't working today.

Highly doubt that anyone would have the same scenario, but I solved it by just using a separate docker container for memcached and connecting my application to that instead.

You are trying to install igbinary extension for PHP 7.2 with PHP 7.4. This cannot work.

For a proper configuration, please follow the Wizard instructions

And not enough information for more help:

Try running apt update, then it should work afterwards.

APT caches the packages available from each repository locally when running apt update. If you install a package, apt will use this cache. However, when a package is updated on the server and the old version gets deleted, apt will try to retrieve a no longer present file. This is indicated by this log output:

Looking at your Dockerfile, you don't have a copy statement which copies the your source code to the container. And in your docker compose you would would be sharing that code using volumes. Hence your code works fine in docker-compose up. But in case of docker run that volume is not shared and hence the error
