### Start Zookeeper Single Instance (Bash)

Source: https://github.com/livealone/sourcemvnlibanalyse/blob/master/sp-cloud/cloud-feign-la/README.md

Starts a single instance of Zookeeper in a Docker container. This is essential for service registration and discovery in a distributed system. The container is configured to restart automatically.

```bash
# 启动单点服务
docker run --name local-zk-single --restart always -p 2181:2181 -d zookeeper
```

### Start Spring Microservice Instances (Java)

Source: https://github.com/livealone/sourcemvnlibanalyse/blob/master/sp-cloud/cloud-feign-la/README.md

Launches multiple instances of a Spring microservice application (cloud-feign-la) using the Java command. Each instance is registered with a specific application name ('feign-la') and assigned a unique server port. This showcases how to deploy multiple replicas of a service.

```java
java -jar .\target\cloud-feign-la-1.0-SNAPSHOT.jar --spring.application.name=feign-la --server.port=9090
java -jar .\target\cloud-feign-la-1.0-SNAPSHOT.jar --spring.application.name=feign-la --server.port=9091
java -jar .\target\cloud-feign-la-1.0-SNAPSHOT.jar --spring.application.name=feign-la --server.port=9092
```

### Connect to Zookeeper using zkCli (Bash)

Source: https://github.com/livealone/sourcemvnlibanalyse/blob/master/sp-cloud/cloud-feign-la/README.md

Connects to a running Zookeeper instance using the zkCli tool within a Docker container. This allows for interaction with the Zookeeper service, such as viewing registered services. It links to a pre-existing Zookeeper container.

```bash
# 连接方式
docker run -it --rm --link local-zk-single:zookeeper zookeeper zkCli.sh -server zookeeper
```

--------------------------------

### Access Service via HTTP (Bash)

Source: https://github.com/livealone/sourcemvnlibanalyse/blob/master/sp-cloud/cloud-feign-la/README.md

Accesses a registered microservice using a simple cURL command. This demonstrates how a service gateway can be used to route requests to the appropriate service instance. Assumes a service is available at localhost:8080.

```bash
# 服务访问方式
curl http://localhost:8080/server
```
