Create a playbook to stop execution after encountering an error in any task.
정답:
- name: Stop on error hosts: all
tasks:
- name: Intentional failure
command: exit 1
ignore_errors: no
Explanation:
By default, Ansible stops on errors unless ignore_errors is set to yes. This ensures errors are addressed before proceeding.

Run a playbook in Automation Controller using an execution environment (EE).
정답:
1. Go to Execution Environments.
2. Add a new EE with the image: registry.example.com/my_execution_env:1.0.
3. Assign the EE to a job template and run the playbook.
Explanation:
Execution environments ensure consistent runtime environments for playbook execution.

Create a playbook to conditionally execute a task based on the presence of a file /tmp/example.
정답:
- name: Conditional execution
hosts: all
tasks:
- name: Create file if it exists
command: touch /tmp/created
when: ansible_facts['distribution'] == "Ubuntu"
Explanation:
Conditional execution using when ensures tasks run only under specific conditions, preventing unnecessary or incorrect operations.

Run a playbook in an EE with a custom inventory file.
정답:
podman run --rm -v $(pwd):/workspace -w /workspace my_execution_env:1.0 ansible-playbook -i custom_inventory.yml site.yml
Explanation:
Using a custom inventory file within the EE ensures that specific hosts are targeted during playbook execution.

Create an inventory plugin configuration for AWS.
정답:
plugin: aws_ec2
regions:
- us-east-1 keyed_groups:
- key: tags.Name prefix: tag_
Explanation:
Inventory plugins like aws_ec2 dynamically fetch hosts from cloud environments, ensuring accurate inventories.

Pull the EE image from the private container registry.
정답:
podman pull registry.example.com/my_execution_env:1.0
Explanation:
Pulling the image retrieves the EE from the registry, making it available locally for use in automation tasks.

Fetch a file from a managed node to the control node using delegation.
정답:
- name: Fetch file to control node hosts: web1
tasks:
- name: Retrieve file fetch:
src: /var/log/example.log
dest: /tmp/example.log
flat: yes
delegate_to: localhost
Explanation:
The fetch module retrieves files from a managed node to the control node, useful for collecting logs or artifacts.

Deploy an EE to Kubernetes for distributed execution.
정답:
1. Push the EE image to a container registry accessible by Kubernetes:
podman push my_execution_env:1.0 registry.example.com/my_execution_env:1.0
2. Create a Kubernetes Pod configuration:
apiVersion: v1
kind: Pod
metadata:
name: ansible-execution
spec:
containers:
- name: execution-env
image: registry.example.com/my_execution_env:1.0
command: ["ansible-playbook", "site.yml"]
volumeMounts:
- name: workspace mountPath: /workspace
volumes:
- name: workspace hostPath:
path: /path/to/workspace
3. Apply the configuration:
kubectl apply -f execution_env_pod.yaml
Explanation:
Deploying an EE to Kubernetes allows for scalable and distributed playbook execution across a cluster.
podman push my_execution_env:1.0 registry.example.com/my_execution_env:1.0

A teammate accidentally pushed sensitive data to the repository. Use an interactive rebase to remove the commit containing the sensitive data.
정답:
git rebase -i HEAD~3
# In the interactive editor, mark the commit with "d" to delete it, then save and exit.
Explanation:
Interactive rebasing enables modification of commit history, such as editing, squashing, or deleting commits, useful for fixing errors.
