Nginx Docker AWS，Nginx无法在多容器中解析127.0.0.11

我正在从事的工作：

nginx-openresty与mecached和docker组合

在nginx中，我可以通过在docker compose it工作文件中指定resolver=127.0.0.11来连接memcached容器

但当我在AWS多容器beanstalk上部署它时，我得到了超时错误

failed to connect: memcache could not be resolved (110: Operation timed out)

但从nginx容器中，我可以ping memcahed

NGINX.conf

location /health-check {
  resolver 127.0.0.11 ipv6=off;
  access_by_lua_block {

      local memcached = require "resty.memcached"
      local memc, err = memcached:new()
      if not memc then
          ngx.say("failed to instantiate memc: ", err)
          return
      end

      memc: set_timeout(1000) -- 1 sec

      local ok, err = memc:connect("memcache", 11211)
      if not ok then
          ngx.say("failed to connect: ", err)
          return
      end

您有一个输入错误：

memc:connect（“memcache”，11211）

应该是

memc:connect（“memcached”，11211）

（您缺少一个“d”）。

更正的.json文件。把它加进去是个错误here@sandeep你也会犯同样的错误<代码>连接失败：无法解析memcache（110:操作超时）您可以重建映像
