Progressive Weather App
New Added Feature
Containerization
It uses Docker to containerized the application. On Dockerfile there are 3 stages, base, testrunner and main.
Testrunner stage used to run unit test. We used the same dockerfile with same base image to run the unit test to make sure the full compatibility with the build image. To run the test, first we need to build and specify the target to testrunner.
docker build -t app-test --target=testrunner .
docker run --rm app-test
The main stage it uses nginx to act as static web server. The nginx config is located on deploy/nginx.conf.
Makefile
Makefile uses to simplify the process. There are 4 processes.
-
Test = run unit test
-
Build = build into docker image
-
Push = push to docker registry
-
Deploy = upgrade kubernetes release using helm
Helm Chart
Helm used to package the application to be easily deployed to kubernetes cluster. With helm we can easily version and manage releases. Helm also support to deploy multiple release of the same app in the same cluster or namespace for case like staging release, canary etc.
Azure Pipeline
Azure pipeline help automate the CICD process. Every push will run the automated unit test (make test), and every tag with prefix release-* will be deployed. Deployment flow:
- Create new tag from any branch you want to deploy
git tag release-v1
git push origin release-v1
- Azure pipeline will automatically trigger build and deploy
