What are some examples of CircleCI YAML configurations?

Can you show me some examples of CircleCI YAML configurations?

Sure! Here are a few examples of CircleCI YAML configurations for different scenarios.

What does a basic CircleCI configuration look like?

A basic CircleCI configuration includes a version, jobs, and workflows. Here's a simple example:

version: 2.1
jobs:
  build:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run: python -m unittest discover
workflows:
  version: 2
  build:
    jobs:
      - build

How can I set up a job to run tests?

You can set up a job to run tests by adding a run step in your job definition. For example:

jobs:
  test:
    docker:
      - image: circleci/python:3.8
    steps:
      - checkout
      - run: pytest tests/

Can I use multiple Docker images in one job?

Yes, you can use multiple Docker images by defining them in the docker section of your job. Here's an example:

jobs:
  build:
    docker:
      - image: circleci/python:3.8
      - image: circleci/postgres:latest
    steps:
      - checkout
      - run: python -m unittest discover
