A buffer overflow occurs when:
- You are using
mysql:5.7.16ormysql:5.7.17 - You map a nonexistent/empty folder to
/etc/mysql/conf.d - Your docker-compose project has a long name
- And you connect to mysql.
docker-compose --project-name some-long-name-that-will-break-mysql up
Wait for mysql to come up. Then run the following in another terminal:
$ docker-compose --project-name some-long-name-that-will-break-mysql run web php -f index.php mysql-5.7.15 # No issues here
$ docker-compose --project-name some-long-name-that-will-break-mysql run web php -f index.php mysql-5.7.17-novol # This works too
$ docker-compose --project-name some-long-name-that-will-break-mysql run web php -f index.php mysql-5.7.17
