dns resolution problems in the fdk images

[atragon]

If one of the name servers in the /etc/resolv.conf file is not working, then dns name resolution that occurs within a container running, for example, fnproject/go:dev, fails even if the other name servers in the /etc/resolv.conf file are able to resolve host names. The failure appears to be caused by the getaddrinfo function: it aborts the processing as soon as it receives the error related to the faulty name server. This is an excerpt of the system trace generated by the address: socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = 3 bind(3, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr(“0.0.0.0”)}, 16) = 0 sendto(3, “\276!\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“A.B.C.D”)}, 16) = 46 sendto(3, “\276!\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“E.F.G.H”)}, 16) = 46 sendto(3, “\276!\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“I.J.K.L”)}, 16) = 46 sendto(3, “\300p\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“A.B.C.D”)}, 16) = 46 sendto(3, “\300p\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“E.F.G.H”)}, 16) = 46 sendto(3, “\300p\1\0\0\1\0\0\0\0\0\0\16my-proxy\2us\6o”..., 46, MSG_NOSIGNAL, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“I.J.K.L”)}, 16) = 46 poll([{fd=3, events=POLLIN}], 1, 2500) = 1 ([{fd=3, revents=POLLIN}]) recvfrom(3, “\276!\201\203\0\1\0\0\0\1\0\0\16my-proxy\2us\6o”..., 512, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“I.J.K.L”)}, [16]) = 111 recvfrom(3, “\300p\201\203\0\1\0\0\0\1\0\0\16my-proxy\2us\6o”..., 512, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr(“I.J.K.L”)}, [16]) = 111 close(3) = 0 write(2, “wget: bad address ’my-proxy”..., 52wget: bad address ‘my-proxy.com:80’ ) = 52
