💡 Hint

Common Mistakes

Using :rw allows writing to the config file inside the container, which is usually not needed.

Using :tmpfs or :cache are not valid for mounting regular files.

The :ro option mounts the config file as read-only inside the container, which is a common practice for config files.

💡 Hint

Common Mistakes

Using default or unrelated config filenames that do not exist in the build context.

Copying a directory instead of a single config file.

The source file mynginx.conf is copied into the image as the main nginx config.

Fix the error in the Docker run command to mount a directory with custom configs.

Nginx

💡 Hint

Common Mistakes

Using just 'conf.d' without './' may cause Docker to look in the wrong place.

Using container paths as source paths causes errors.

The local directory ./conf.d must be relative or absolute path on the host to mount correctly.

Fill both blanks to create a Dockerfile snippet that sets the working directory and copies the config.

Nginx

WORKDIR [1]
COPY [2] ./

Drag options to blanks, or click blank then click option'

A/etc/nginx

Bmynginx.conf

C/usr/share/nginx/html

Ddefault.conf

💡 Hint

Common Mistakes

Setting working directory to the wrong path.

Copying the wrong config filename.

Setting /etc/nginx as working directory and copying mynginx.conf there places the config correctly.

hard

Fill all three blanks to define a volume for nginx logs and expose port 80 in Docker Compose.

Nginx

version: '3'
services:
  web:
    image: nginx
    ports:
      - '[1]:80'
    volumes:
      - '[2]:/var/log/nginx'
    restart: [3]

Drag options to blanks, or click blank then click option'

Bnginx-logs

D80

💡 Hint

Common Mistakes

Using port 80 on host may conflict with existing services.

Forgetting to define a restart policy causes container to stop on failure.

Port 8080 is mapped to container port 80, volume nginx-logs stores logs, and restart policy always keeps the container running.
