PHP ZTS Container stops immediately

Question

I am attempting to create a Docker container using the official PHP 7.4 ZTS image without making any modifications. However, when I start the container, it immediately stops as if the entrypoint is incorrect.

My Dockerfile contains the following content: FROM php:7.4-zts-alpine

This is the result when I run docker compose up.

I have tried using other official ZTS images, but they also do not work.

It was not. It is not necessary for PHP FPM but it seems that is necessary for ZTS. Thank you. — Ivan Stadius, Feb 20 '23 at 20:24

If you put tty: true in the docker-compose.yml, you will be able to keep the container running. You can also do this by using the -t flag in the docker command.

The reason FPM doesn't require it to keep the container running is that FPM is the entrypoint.

With ZTS, bash is the entrypoint -- So, once you add a tty: true to the container, bash will be able to create interactive session and the container will (or at least should be) started with bash as the entrypoint.
