I have a custom Docker build of nginx and php-fpm that I am pretty sure was working until recently. I am now getting the error mentioned above during a build using the DockerFile below when using 8.0-fpm, but not with 8.1.1-fpm-bullseye, although there are some other issues with using 8.1.1 in some of the PHP code (deprecations and warnings).

Any suggestions regarding optimizing the build would also be appreciated.
I have another question about saving the built image to Docker Hub if I have an account to store private images. e.g. Below is a snippet from the docker-compose.yml file. It isn't really clear to me if it is possible to bypass the build and just use a built image that I store on my Docker Hub account. It seems like if I comment out the build line, then it will access the dockerhub image to build the container, but it isn't clear to me if some of the other commands in the DockerFile (i.e. entrypoint, composer install, etc.) are executed in that case.
My goal is to arrive at what I consider "stable" images and then make those available on DockerHub instead of having to build the image on a new machine everytime. Also, probably going to run into some issues with an M1 Chip on a mac once I get one.
build: php-fpm-nginx # comment out to use the built image
image: sdscotti/dockerhubimage

restart: unless-stopped
ports: ["443:443"]

PHP 8.0.15 and 8.1.2 has a bug which is breaks compile sockets extension.
You have a two options:
