demo

Demonstration of the cluster that have three environments(main, feature-1, feature-2) and that is deployed application with Services A, B, C (Web servers) and Service MySQL.

Usage

Create Resources

Please follow steps to create there resources.

• Proxy Controller
• Proxy A/B/C
• Service A[main, feature-1]
• Service B[main, feature-2]
• Service C[main]
• Service MySQL[main, feature-1, feature-2]
• Proxy Controller DB

Docker Compose with One Host

One host has all resources.

cd docker/all-in-one
docker compose up 

Docker Compose with Three Hosts

Separated Web Servers, a MySQL Server, and Proxy Controller DB

Host Web

It has the following resources.

• Proxy Controller
• Proxy A/B/C
• Service A[main, feature-1]
• Service B[main, feature-2]
• Service C[main]

cd docker/without-db
vim docker-compose.yaml # Please replace the IP address 192.168.0.3 with that of the Host MySQL and 192.168.0.4 with that of the Host Controller DB.
docker compose up

Host MySQL

It has Service MySQL[main, feature-1, feature-2].

cd docker/only-service-mysql
docker compose up

Please confirm that the Host Web can access the port 13306, 13307, and 13308 of the Host MySQL.

Host Controller DB

It has Proxy Controller DB.

1. Install MySQL
2. Create MySQL user picop with password picop
3. Configure it to allow the Host Web to login picop
4. Create database picop
5. Create tables referring to proxy-controller/db-schema

Please confirm that the Host Web can access the port 3306 of the Host Controller DB.

Kubernetes

Please prepare Kubernetes cluster and the other two hosts.

Kubernetes Cluster

It has the following resources.

• Proxy Controller
• Proxy A/B/C
• Service A[main, feature-1]
• Service B[main, feature-2]
• Service C[main]

cd kubernetes/manifests
vim proxy-mysql.yaml # Please replace the IP address 192.168.0.3 with that of the Host MySQL.
vim proxy-controller.yaml # Please replace the IP address 192.168.0.4 with that of the Host Controller DB.
kubectl apply namespace.yaml
kubectl apply proxy-controller.yaml
kubectl apply proxy-a.yaml
kubectl apply proxy-b.yaml
kubectl apply proxy-c.yaml
kubectl apply proxy-mysql.yaml
./script/create-service-a.sh main | kubectl apply -f -
./script/create-service-b.sh main | kubectl apply -f -
./script/create-service-c.sh main | kubectl apply -f -
./script/create-service-a.sh feature-1 | kubectl apply -f -
./script/create-service-b.sh feature-2 | kubectl apply -f -

Host MySQL and Host Controller DB

It is the same as the case of Docker Compose with Three Hosts.

Configure Proxy Controller

Please get Proxy Controller URL. If Docker Compose, it is http://<the Host IP address with Proxy Controller>:8080. If Kubernetes, it is http://<k8s cluster IP address>:31001.

cs script
./register-proxies.sh <Proxy Controller URL>
vim ./register-routes.yaml # Please replace the IP address 192.168.0.3 with that of the Host MySQL.
./register-routes.sh <Proxy Controller URL>

Send Requests with PiCoP

You can use picop-curl.

Please get Proxy A URL. If Docker Compose, it is http://<the Host IP address with Proxy A>:9001. If Kubernetes, it is http://<k8s cluster IP address>:31002.

data{ id: 0, content: test-main }
data{ id: 1, content: test-feature-100 }

Environment feature-1

$ picop-curl --env-id feature-1 --url <Proxy A URL> --method POST --data test-feature-1
