Permission issue when running with docker-compose

[s3inlc]

When just using the provided docker compose in the repository root, there seems to be a permission issue

Steps:

docker-compose build
docker-compose up

After the Hashtopolis installation is done, when trying to register a new agent, it results in a internal server error when registering an agent:

[Mon Aug 22 12:24:16.016214 2022] [php:error] [pid 34] [client 172.18.0.1:46202] PHP Fatal error:  Uncaught Exception: Could not open lockfile '/var/www/html/inc/utils/locks/log.lock'! in /var/www/html/inc/utils/Lock.class.php:19

It seems that in the source directory, the permissions are not proper, even though the owner in the Dockerfile COPY command is set (COPY --chown=www-data:www-data ./src/ /var/www/html/).
