Fix Mongodb start error: FileNotOpen: Failed to open "/opt/bitnami/mongodb/logs/mongodb.log"

[anoduck]

Error

Most recent version of mongodb fails to start on docker-compose up -d with error:
FileNotOpen: Failed to open "/opt/bitnami/mongodb/logs/mongodb.log"

Fix

After some tinkering a simple resolution was discovered to resolve the problem. Create a local volume inside the CWD to hold the log file and create the log file.

1. In your shell:
   mkdir -p logs && touch logs/mongodb.log

2. Add the volume to docker-compose.yml below the bitnami volume:

volumes:
  - .:/bitnami
  - ./logs:/opt/bitnami/mongodb/logs  

3. You may now create the containers and start the application.
   docker-compose up -d
