Behat container keeps exiting - docker

Question

I'm using the following code to create a Behat docker container:
version: '3'
services:
behat:
container_name: behat.test
image: docksal/behat
# command: tail -F anything
# tty: true
# ports:
# - 4444:4444
# restart: always
But I'm experiencing a persistent problem with the container continually exiting with a code 1 as a result I can't interact with the container.
All the commented out portions of the code are what I have tried to resolve the issue.
Here is the output for the Behat container when I run docker-compose up -d --build:
d8c515771e4d docksal/behat "behat" 6 seconds ago Exited (1) 5 seconds ago behat.test
Update
I found Behat was reporting the following error :
`FeatureContext` context class not found and can not be used.

Answer 1

FeatureContext context class not found and can not be used.
This means behat fails to find features which needed, you could use behat --init to init a one.
$ docker run --rm -v $(pwd):/src docksal/behat --init
+d features - place your *.feature files here
+d features/bootstrap - place your context classes here
+f features/bootstrap/FeatureContext.php - place your definitions, transformations and hooks here
Then in your host, there will be a features folder, then run the command again see it's ok now:
$ docker run --rm -v $(pwd):/src docksal/behat

For docker-compose, it's same, you need to assure there is features mount to the container. You could reference official folder structure to have your design, a workable step as next:
In current folder:
docker run --rm -v $(pwd):/src docksal/behat --init
Write a docker-compose.yaml like next:
version: "2.1"
services:
# Behat
behat:
hostname: behat
image: ${BEHAT_IMAGE:-docksal/behat}
volumes:
- .:/src
# Run a built-in web server for access to HTML reports
ports:
- 8000:8000
entrypoint: "php -S 0.0.0.0:8000"
docker-compose up -d
$ docker ps
