DevOps实战项目：微服务CI/CD管道构建与应用部署策略

# Capstone Project (Cloud DevOps Engineer) Capstone project for Udacity Dev-Ops Nanodegree: develop a CI/CD pipeline for micro services applications with either blue/green deployment or rolling deployment. ## CI CD Pipeline The CI CD pipeline is as follows for this project. For initial set up: - Set up jenkins - Install dependencies for local development - Create AWS infrastructure For application development: - Make development change - Commit to git - Update AWS stack using `./awsCoUp.sh` commands listed below if required - Push to repository - Jenkins build automatically runs based on triggers - Files are linted - Docker image build and uploaded to ECR - ECS tasks updated to run new Docker image using rolling deployment ## Running the stuff There is a `Makefile` that contains lots of useful commands. Running `make` will list them, like the below output. ```text help: Show this help. setup: Create the virtial environment to run this project env: List the environment versions lint: Check the validity of the project files test: Run the tests for this prject install: Install the required imports for this project docker-build: Build the docker image and list available docker images docker-upload: Upload the docker image to AWS start-api: Run the python application locally ``` ## Creating the infrastructure From the base of this repository run the following to create or update the deployment. ```bash aws configure # set to credentials with appropriate access cd scripts; ./awsCoUp.sh network ../cloudformation/01-network.yml ../cloudformation/01-network-parameters.json; cd .. # Wait for the network stack to be complete cd scripts; ./awsCoUp.sh cluster ../cloudformation/02-cluster.yml ../cloudformation/02-cluster-parameters.json; cd .. ``` ## Jenkins set up Full jenkins set up details can be found in `jenkinsSetup.md`. ## Output From running the above the following will be created. The application is currently running [here](http://clust-applb-c1p26laf80l1-69580312.us-east-1.elb.amazonaws.com/) is a link to the load balancer. AWS Stacks:     Jenkins build when the lint fails:  Jenkins build when the lint passes and deploys to ECR:  ECR with new image uploaded:  Hello world application running:  <h3>Author</h3> <a href = "https://github.com/qasim1020/Capstone-Project-Devops">GitHub</a>
