Exam 350-901 topic 1 question 175 discussion

asked chatgpt In a GitLab CI/CD pipeline, the after_script is used to specify commands that should be run after the script has executed, regardless of the result of the script. It's commonly used for cleanup, notifying other services, or any other finishing steps. Based on the previous exhibit which is about deploying infrastructure for a containerized application, after building the container and running an Ansible playbook, you might want to include commands in the after_script section that: Push the built Docker image to a Docker registry if the build and Ansible steps were successful. Remove the Docker container to clean up the CI/CD environment. Collect logs or artifacts from the container for further analysis or debugging.

The main reason I prefer D instead of C is because of the second line of C where it specified the $DOCKER USERNAME and $DOCKER REPOSITORY. This is incorrect syntax, but also wouldn't be needed anyway since these are specified earlier on in the docker login command. If it wasn't for that, I would think C is more appropriate. However, in my opinion, this can't be right as the syntax is incorrect.

After a conversation with chatgpt: Given the requirement to automatically deploy infrastructure for a containerized application and the presence of the docker login command in the script, it is indeed more appropriate to prioritize option C (docker push) over option D (docker logout) in the after_script section. The docker push command ensures that the built container image is pushed to the Docker registry, making it available for deployment. On the other hand, docker logout simply performs a logout action, which may not be directly related to the deployment process. Therefore, in this specific scenario, it is recommended to include option C (docker push) in the after_script section rather than option D (docker logout).

I will take the answer as D, because neither answer A,B,C got incorrect command format.

Correct answer seems to be D - docker logout https://github.com/willhallonline/docker-ansible/blob/master/.gitlab-ci.yml https://docs.docker.com/engine/reference/commandline/logout/

I think C is correct. First the image needs to be pushed to the repo.

D https://docs.docker.com/engine/reference/commandline/logout/
