可以使用HTTP API来检查配置
[root@h104 consul]# curl http://localhost:8500/v1/health/state/critical
[{"Node":"a2","CheckID":"service:web","Name":"Service 'web' check","Status":"critical","Notes":"","Output":"","ServiceID":"web","ServiceName":"web","CreateIndex":593,"ModifyIndex":593}][root@h104 consul]#
[root@h104 consul]#
----------
[root@docker ~]# curl http://localhost:8500/v1/health/state/critical
[{"Node":"a2","CheckID":"service:web","Name":"Service 'web' check","Status":"critical","Notes":"","Output":"","ServiceID":"web","ServiceName":"web","CreateIndex":593,"ModifyIndex":593}][root@docker ~]#
[root@docker ~]#
可以在任意一个节点上进行检查
和服务一样,健康检查也可以使用 HTTP API 来动态地进行添加,删除和修改
Consul 提供了一个简单的键值存储机制,可以使用这个特性来存储动态配置,服务协调,主节点选举和其它一些功能
[root@h104 consul]# curl -v http://localhost:8500/v1/kv/?recurse
* About to connect() to localhost port 8500 (#0)

因为没有任何值,所以反馈结果为 404
