docker-php's Issues

PHP "StdOut" Logs are Actually Delivered to Host as StdErr

Summary: When using behance/docker-php:7.4, any logging or stream writing within a PHP application that is configured for stdout (e.g., php://stdout) actually arrives at the docker host on stderr.

To reproduce:

git clone [email protected]:jimdelois/behance-docker-php-stdout-bug
cd behance-docker-php-stdout-bug
docker-compose up -d

Enter the Docker Machine Name for your local

DOCKER_MACHINE_NAME=""

Send a request to the container:

curl -XGET http://$(docker-machine ip $DOCKER_MACHINE_NAME):$(docker port badboy 8080 | awk '{split($0,a,":"); print a[2]}')

Examine the Docker logging by examining the raw container logs from the docker host
(e.g., docker-machine ssh $DOCKER_MACHINE_NAME, thence tail -F /var/lib/docker/containers/$CONTAINER_ID/$CONTAINER_ID-json.log):

• Actual: {"log":"I want a Bad Boy Sandwich\n","stream":"stderr","time":"2020-11-19T06:18:08.672226893Z"}
• Expected: {"log":"I want a Bad Boy Sandwich\n","stream":"stdout","time":"2020-11-19T06:18:08.672226893Z"}

Notes:

• Observe baseline intended functionality in the repo file jimdelois/behance-docker-php-stdout-bug/public/index.php
• Raw PHP stream explicitly set to php://stdout; Loggers (e.g., Monolog) in production applications typically use this stream
• The unexpected outcome is that containers are sending "normal" PHP output to STDERR, which affects metrics in AWS, FluentD routing, Sumo queries, etc.

Support Empty Environment Variables

run.sh fails when environment variables are set to empty strings

Allow for Runtime Configuration of apc.shm_size

The default shm_size value is "32M" which is on the small side. It would be nice to override this with an environment variable. Documentation for shm_size can be found here https://www.php.net/manual/en/apc.configuration.php#ini.apc.shm-size
