Troubleshooting 🧐

On MacOS while executing init scripts happens error:

/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/0001-init.sh
/usr/local/bin/docker-entrypoint.sh: /docker-entrypoint-initdb.d/0001-init.sh: /bin/bash: bad interpreter: Permission denied

For fix this needs to add execute permission for scripts:

find ./configs/postgres/scripts -type f \( -iname \*.sh -o -iname \*.sql \) -exec chmod +x {} +
