- A
docker run -d -p 8080:80 -e ENV=production -v /data:/app/data myapp:latest
Correctly runs the container detached with port mapping, environment variable, and bind mount.
- B
set -e
set -e causes the script to exit immediately if any command fails, fulfilling requirement 1.
- C
docker build -t myapp:latest .
Why wrong: This builds the image but does not address the exit-on-error requirement.
- D
docker build --tag myapp:latest .
Why wrong: This builds the image but does not include the container run command.
- E
docker run -d -p 8080:80 -eENV=production -v /data:/app/data myapp:latest
Why wrong: Missing space after -e causes the environment variable to be parsed incorrectly.

XK0-005 Scripting, Containers, and Automation Practice Question
This XK0-005 practice question tests your understanding of scripting, containers, and automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps engineer is writing a Bash script to automate deployment of a containerized application. The script must: (1) exit immediately if any command fails, (2) build a Docker image with tag 'myapp:latest' from the current directory, (3) run a container from that image in detached mode with port mapping 8080:80, (4) set environment variable ENV=production inside the container, and (5) bind mount a host directory /data to /app/data inside the container. Which TWO of the following snippets should be included in the script to meet these requirements? (Choose TWO.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"immediately / without restart"Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
docker run -d -p 8080:80 -e ENV=production -v /data:/app/data myapp:latest
Option A (set -e) is needed to exit on error. Option E (docker run -d -p 8080:80 -e ENV=production -v /data:/app/data myapp:latest) correctly runs the container detached with port mapping, environment variable, and bind mount. Option B omits -e, Option C has syntax error (missing quotes), Option D repeats --tag but is incomplete.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the XK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
