Docker containerization in ML Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the base image in a Dockerfile.

ML Python

FROM [1]

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

BCOPY . /app

CRUN apt-get update

DCMD python app.py

💡 Hint

Common Mistakes

Using RUN or COPY instead of FROM as the first instruction.

Specifying commands instead of an image name.

The FROM instruction specifies the base image for the Docker container. 'python:3.8-slim' is a valid base image.

medium

Complete the code to copy the current directory contents into the container.

ML Python

COPY [1] /app

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

Arequirements.txt

Bapp.py

C/usr/src/app

D.

💡 Hint

Common Mistakes

Copying a single file instead of the whole directory.

Using an absolute path from the container as source.

COPY . /app copies all files from the current directory into the /app directory inside the container.

3fill in blank

hard

Fix the error in the command to install dependencies inside the container.

ML Python

RUN pip install [1]

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

Arequirements.txt

B-r requirements.txt

Cinstall requirements.txt

Dpip install -r requirements.txt

Attempts:

💡 Hint

Common Mistakes

Putting the whole command including 'pip install' in the blank.

Omitting the '-r' flag.

The correct pip command to install from a requirements file is 'pip install -r requirements.txt'. In Dockerfile RUN, only the arguments after pip install are needed, so '-r requirements.txt' is correct.

4fill in blank

hard

Fill both blanks to set the working directory and the command to run the app.

ML Python

WORKDIR [1]
CMD ["python", "[2]"]

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

A/app

Bapp.py

Cmain.py

D/usr/src/app

Attempts:

💡 Hint

Common Mistakes

Using an incorrect path for WORKDIR.

Specifying the wrong script name in CMD.

WORKDIR /app sets the working directory inside the container. CMD ["python", "app.py"] runs the app.py script when the container starts.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps file names to their sizes if size is greater than 1000 bytes.

ML Python

file_sizes = [1]: os.path.getsize([2]) for [3] in files if os.path.getsize([3]) > 1000

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

💡 Hint

Common Mistakes

Using different variable names in different parts of the comprehension.

Not using the variable as the key in the dictionary.

The comprehension uses 'f' as the variable for each file name. The dictionary maps 'f' to its size using os.path.getsize(f).
