Prerequisites

• docker
• with docker-compose

Usage

You can run the images from docker hub which is preferred or built it on your own. First: Start Docker daemon and check with docker ps

Quick Start (docker-hub)

• Copy the docker-compose.yml locally in a desired folder and run

$ docker-compose up -d
# to follow the logs
$ docker-compose logs -tf
# to shutdown
$ docker-compose down

Built it on your own

• Run docker-compose -f docker-compose-local.yml up -d which will
  • It builds the web app war in a staged build, packs it into a docker tomcat8 container, and sets the user tomcat with password admin for the Management Console at http://localhost:8888/
  • Initializes the MySQL Database docker container with the db user defined in hibernate.cfg.xml
  • Sets up both containers and make the legacy webshop available under http://localhost:8888/EShop-1.0.0
• Follow the logs via docker-compose -f docker-compose-local.yml logs -tf
• To shutdown the containers run docker-compose -f docker-compose-local.yml down

Database Cleanup

If you change the user and password of the MySQL database, you should run

$ docker-compose rm -v
$ rm -rf .data

Kubernetes

First of all, the different components have to be packaged into Docker images. To do this, the following command has to be executed per Dockerfile:

docker build -t <your-image-name>:<your-version> -f <path-to-dockerfile> .

Then next, the individual Kubernetes configurations must be deployed. To do this, they must be deployed in the following order:

1. pvc-mysql.yaml
2. mysql-legacy.yaml
3. mysql-category.yaml
4. mysql-product.yaml
5. category-service.yaml
6. product-service.yaml
7. webshop.yaml
8. istio.yaml

The configurations can be deployed with the following command:

kubectl apply -f <file-name>

More useful commands:

• kubectl port-forward svc/<service-name> <outside-port>:<inside-port> -n <namespace>
• kubectl get ns default --show-labels
• kubectl label namespace default istio-injection=enabled
