# docker-rabbitmq-clustering

## network partition を発生させる例

```sh

pumba netem --tc-image gaiadocker/iproute2 --duration 120s loss --percent 100 docker-rabbitmq-clustering_rabbit2_1 docker-rabbitmq-clustering_rabbit3_1

```

しばらくすると log に

```

ダウン判定が出力される，このときメッセージを適当に rabbit1 へ publish する．

```

120s が経過して loss がなくなると，inconsistent になる．

## PerfTest

`docker-compose up -d` で作成された network に対して PerfTest を実行する．

```sh

docker run -it --rm --network docker-rabbitmq-clustering_default \

    pivotalrabbitmq/perf-test:latest \

    --uris amqp://rabbit1,amqp://rabbit2,amqp://rabbit3

```
