Thank you very much for your quick response.
Everything works great.
By adding [ ] to enclose the IPv6 address additionally, I got running state
of apisix server.
```
NAME READY STATUS RESTARTS AGE
apisix-server-65fd5bb697-d8xv6 1/1 Running 0 26s
```
I don't have experience of coding Lua. FYI, let me provide my final script.
```
local function local_dns_resolver(file_path)
local file, err = io_open(file_path, "rb")
if not file then
return false, "failed to open file: " .. file_path .. ", error
info:" .. err
end
local dns_addrs = {}
for line in file:lines() do
local addr, n = line:gsub("^nameserver%s+(%d+%.%d+%.%d+%.%d+)%s*$",
"%1")
local addr6, n6 = line:gsub("^nameserver%s+([^%s]+)%s*$", "%1")
if n == 1 then
table_insert(dns_addrs, addr)
end
if n6 == 1 then
table_insert(dns_addrs, "[" .. addr6 .. "]")
end
end
file:close()
return dns_addrs
end
```
Thank you so much @spacewander .
