Exercise: CircleCI

It is easy to look at build servers as a nice to have when they are a must-have for DevOps best practices. One ubiquitous cloud-based build server is CircleCI. In this exercise, you will incorporate many of the concepts from this course: Docker, Makefiles, and build systems.

Instructions

• Follow these instructions for setting up local CircleCI
• Change the template below and add to your Makefile (this template is similar to what we used in earlier lessons)
• Run validate-circleci and run-circleci-local for your project, making sure to change any values that are unique to your project.

Makefile template

setup:
    python3 -m venv ~/.udacity-devops

install:
    pip install --upgrade pip &&\
        pip install -r requirements.txt

test:
    #python -m pytest -vv --cov=myrepolib tests/*.py
    #python -m pytest --nbval notebook.ipynb

validate-circleci:
    # See https://circleci.com/docs/2.0/local-cli/#processing-a-config
    circleci config process .circleci/config.yml

run-circleci-local:
    # See https://circleci.com/docs/2.0/local-cli/#running-a-job
    circleci local execute

lint:
    hadolint demos/flask-sklearn/Dockerfile
    pylint --disable=R,C,W1203 demos/**/**.py

all: install lint test
