Redis过滤器如何与Envoy代理一起使用
1.克隆源码到机器
[root@cx--0002 ~]# git clone https://github.com/envoyproxy/envoy Cloning into 'envoy'... remote: Enumerating objects: 70, done. remote: Counting objects: 100% (70/70), done. remote: Compressing objects: 100% (58/58), done. remote: Total 93652 (delta 13), reused 28 (delta 11), pack-reused 93582 Receiving objects: 100% (93652/93652), 35.16 MiB | 601.00 KiB/s, done. Resolving deltas: 100% (70765/70765), done. [root@cx--0002 ~]# ls anaconda-ks.cfg envoy wordpress-mysql [root@cx--0002 ~]# ls envoy/ api ci configs DEPRECATED.md examples include NOTICE PULL_REQUEST_TEMPLATE.md REPO_LAYOUT.md SECURITY_RELEASE_PROCESS.md support VERSION bazel CODE_OF_CONDUCT.md CONTRIBUTING.md DEVELOPER.md EXTENSION_POLICY.md ISSUE_TEMPLATE.md OWNERS.md README.md restarter source test windows BUILD CODEOWNERS DCO docs GOVERNANCE.md LICENSE PULL_REQUESTS.md repokitteh.star security STYLE.md tools WORKSPACE [root@cx--0002 ~]# cd envoy/examples/redis/ [root@cx--0002 redis]# ls docker-compose.yaml Dockerfile-proxy Dockerfile-redis envoy.yaml README.md
2.安装docker-compose
[root@cx--0002 redis]# curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 617 0 617 0 0 650 0 --:--:-- --:--:-- --:--:-- 650 100 15.4M 100 15.4M 0 0 1353k 0 0:00:11 0:00:11 --:--:-- 2355k [root@cx--0002 redis]# chmod +x /usr/local/bin/docker-compose [root@cx--0002 redis]# docker-compose ps Name Command State Ports ------------------------------
3.创建redis沙箱
[root@cx--0002 redis]# docker-compose up -d Creating network "redis_envoymesh" with the default driver Building proxy Step 1/2 : FROM envoyproxy/envoy-dev:latest Trying to pull repository docker.io/envoyproxy/envoy-dev ... latest: Pulling from docker.io/envoyproxy/envoy-dev 35b42117c431: Already exists ad9c569a8d98: Already exists 293b44f45162: Already exists 0c175077525d: Already exists 720b18d7211c: Pull complete 7e82cb71a605: Pull complete 8dd5fbb71c59: Pull complete cd8d5f15933d: Pull complete e7e9de9472a4: Pull complete Digest: sha256:5d558d699eeb219f672e771d9ab7d455f0c23ecf8cbe81e2fed2bcc4d16fbe21 Status: Downloaded newer image for docker.io/envoyproxy/envoy-dev:latest ---> 66dad96a6e23 Step 2/2 : CMD /usr/local/bin/envoy -c /etc/envoy.yaml -l debug --service-cluster proxy ---> Running in 91d0aa4af229 ---> 939322cd01f3 Removing intermediate container 91d0aa4af229 Successfully built 939322cd01f3 WARNING: Image for service proxy was built because it did not already exist.

Creating redis_proxy_1 ... done Creating redis_redis_1 ... done [root@cx--0002 redis]# docker-compose build Building proxy Step 1/2 : FROM envoyproxy/envoy-dev:latest ---> 66dad96a6e23 Step 2/2 : CMD /usr/local/bin/envoy -c /etc/envoy.yaml -l debug --service-cluster proxy ---> Using cache ---> 939322cd01f3 Successfully built 939322cd01f3 Building redis Step 1/1 : FROM redis ---> 3c41ce05add9 Successfully built 3c41ce05add9
[root@cx--0002 redis]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ef3799105b89 redis_redis "docker-entrypoint..." About a minute ago Up About a minute 0.0.0.0:6379->6379/tcp redis_redis_1 d851feb8d172 redis_proxy "/docker-entrypoin..." About a minute ago Up About a minute 0.0.0.0:1999->1999/tcp, 0.0.0.0:8001->8001/tcp, 10000/tcp redis_proxy_1
4.使用redis-cli发出一些Redis命令，并验证它们是否通过envoy路由
//注意端口号 > redis-cli -h localhost -p 1999 set foo foo OK > redis-cli -h localhost -p 1999 set bar bar OK > redis-cli -h localhost -p 1999 get foo "foo" > redis-cli -h localhost -p 1999 get bar "bar"
转到http://localhost:8001/stats?usedonly&filter=redis.egress_redis.command并验证以下统计信息
redis.egress_redis.command.get.total: 2 redis.egress_redis.command.set.total: 2

[root@cx--0002 ~]# curl http://localhost:8001/help admin commands are: /: Admin home page /certs: print certs on machine /clusters: upstream cluster status /config_dump: dump current Envoy configs (experimental) /contention: dump current Envoy mutex contention stats (if enabled) /cpuprofiler: enable/disable the CPU profiler /healthcheck/fail: cause the server to fail health checks /healthcheck/ok: cause the server to pass health checks /heapprofiler: enable/disable the heap profiler /help: print out list of admin commands /hot_restart_version: print the hot restart compatibility version /listeners: print listener info /logging: query/change logging levels /memory: print current allocation/heap usage /quitquitquit: exit the server /ready: print server state, return 200 if LIVE, otherwise return 503 /reset_counters: reset all counters to zero /runtime: print runtime values /runtime_modify: modify runtime values /server_info: print server version/status information /stats: print server stats /stats/prometheus: print server stats in prometheus format
