Error starting userland proxy #562

Open gullitmiranda opened 9 years ago

gullitmiranda commented 9 years ago

If the docker change of IP is possible can be conflicts in libnss-resolver on Linux.

You need to make it better, it may be necessary to change src/agent/configure.js, so it can cope with this change. issue reported in: https://gitter.im/azukiapp/azk/pt?at=563b3f3d5680530d27049390 (pt-BR)

For me this happened: On ubuntu 14 we ran apt-get dist-upgrade which brought azk from 0.15 to 0.16.1 and docker to 1.9. Trying to start azk did this:

$ azk agent start
...
azk: Starting azk dns service...
azk: Error: HTTP code is 500 which indicates error: server error - Cannot start container 4efbd5f4bfff9e5be91ad2686df06d4cfb15f3869cb1f61c5e053423c189641d: failed to create endpoint dev.azk.io_type.daemon_mid.ce833fc9c9_sys.dns_seq.1_uid.f6967a908a on network bridge: Error starting userland proxy: listen udp 172.17.42.1:53: bind: cannot assign requested address

Note that also there were azktcl images left in created state

$ docker ps -a

This all cleared up by following @gullitmiranda suggestion to rm -rf /etc/resolver/dev.azk.io (and other custom domains we had in there).
