Toxiproxy Test

1. Setup toxiproxy

1, using docker to run shopify/toxiproxy
$ docker pull shopify/toxiproxy
$ docker run -it shopify/toxiproxy

2,install toxiproxy-cli

wget https://github.com/Shopify/toxiproxy/releases/download/v2.1.4/toxiproxy-cli-linux-amd64
chmod +x toxiproxy-cli-linux-amd64
mv toxiproxy-cli-linux-amd64 /bin/toxiproxy-cli
tixiproxy-cli ls
Get http://localhost:8474/proxies: dial tcp [::1]:8474: connect: connection refused

checked： 8474 is listenor for toxiproxy http.
so use bin code to run toxiproxy or use docker run -itd —net=host shopify/toxiproxy

3. use toxiproxy

3.1 install redis

3.2 create myredis in toxiproxy

toxiproxy-cli create myredis -l 0.0.0.0:26379 -u 127.0.0.1:6379 Created new proxy myredis
toxiproxy-cli ls Name Listen Upstream Enabled Toxics myredis [::]:26379 127.0.0.1:6379 enabled None
Hint: inspect toxics with toxiproxy-cli inspect
[root@node43 Linux_ssr_script]# redis-cli 127.0.0.1:6379> quit

3.3 set latency

[root@node43 Linux_ssr_script]# toxiproxy-cli toxic add myredis -t latency -a latency=1000
Added downstream latency toxic ‘latency_downstream’ on proxy ‘myredis’
[root@node43 Linux_ssr_script]#
[root@node43 Linux_ssr_script]# redis-cli -h 127.0.0.1 -p 26379 127.0.0.1:26379

put a “asdasdasd” (error) ERR unknown command put, with args beginning with: a, asdasdasd, (1.00s) 127.0.0.1:26379> quit

docker ps -a

so use bin code to install toxiproxy is better.
