# Memberlist

A basic http key/value example of how to use [hashicorp/memberlist](https://github.com/hashicorp/memberlist)

## Install

```shell
go get github.com/asim/memberlist
```

## Usage

```shell

-members="": comma seperated list of members
-port=4001: http port
```

### Create Cluster

Start first node
```shell
memberlist
```

Make a note of the local member address
```
Local member 192.168.1.64:60496

```

Start second node with first node as part of the member list
```shell
memberlist --members=192.168.1.64:60496 --port=4002
```

You should see the output
```
