+
+Currently, you can deploy and operate a PipeCD Control Plane on a Kubernetes cluster or [on Amazon ECS](./control-plane-on-ecs.md).
+However, some developers would like to build a Control Plane more easily for introduction or development.
+This blog shows you how to install a PipeCD Control Plane on local machine easily.
+
+This blog is for those who would like to:
+- begin using PipeCD and experiment its features instantly, including Control Plane and Piped
+
+### Architecture
+
+The general architecture of PipeCD Control Plane is as below.
+![](/images/control-plane-components.png)
+
+> Note: See [Architecture Overview](docs/user-guide/managing-controlplane/architecture-overview/) doc for details.
+
+In this blog, you will build a Control Plane by these containers:
+
+- Server: pipecd server
+- Ops: pipecd ops
+- Cache: Redis
+- Data Store: MySQL
+- File Store: MinIO
+
+### Installation of Control Plane
+
+1. Get the demo codes from https://github.com/pipe-cd/demo/blob/main/control_plane/docker-compose/
+
+2. Execute the below command for docker-compose.yaml you got in [1.].
+
+```sh
+docker-compose up
+```
+
+After executing the above command, you will see logs like below if success.
+
+```log
+pipecd-server-1   | successfully loaded control-plane configuration
+pipecd-server-1   | successfully connected to file store
+pipecd-server-1   | successfully connected to data store
+pipecd-server-1   | grpc server will be run without tls
+pipecd-server-1   | grpc server will be run without tls
+pipecd-server-1   | grpc server is running on [::]:9080
+pipecd-server-1   | grpc server is running on [::]:9083
+pipecd-server-1   | grpc server will be run without tls
+pipecd-server-1   | admin server is running on 9085
+pipecd-server-1   | grpc server is running on [::]:9081
+pipecd-server-1   | start running http server on :9082
+```
+
+### To confirm: Access the console of the Control Plane
+
+1. Access http://localhost:8080 on your web browser.
+
+2. Enter a value as below and `CONTINUE`.
+   - `Project Name`: `control-plane-local`
+
+3. Enter values as below and `LOGIN`.
+   - `Username`: `hello-pipecd`
+   - `Password`: `hello-pipecd`
+
+4. You will see the applications page. Success!

+
+### Clean up
+
+To clean up the Control Plane, execute the below command.
+
+```sh
+docker-compose down
+```
+
+> Note: By following commands instead of above one, you can keep data such as Piped or applications on the Control Plane even after restarting/updating the server component.
+
+```sh
+# Restart only the server component.
+docker-compose rm -fsv pipecd-server
+docker-compose up pipecd-server
+```
