Paul Bellamy 6b5f35e574 [proxy] Only replace the request body if we've modified it. 
This is a temporary fix for a failure in docker-py tests:
"test_valid_no_config_specified".

Matthias Radestock 375af0a7b9 Improve log messages for when the proxy ignores a container 
- 'ignoring' could be misread as 'dropped request', so change that to
  'leaving container alone'
- more elaborate reasons

Paul Bellamy 4958b8d37a [proxy] Mount /w from the host for weavewaited containers 
We set it at container create. Had tried also setting it at start, but
it seems to cause weird behaviour, and there is no way to do it from the
CLI.

Michael Bridgen c44c61dc83 Merge branch '1103-proxy-chunking' of github.com:weaveworks/weave into pr1112 2015-07-20 15:09:50 +01:00
Paul Bellamy 11663dd29f [proxy] rewrote chunked response handler 
1) We cannot send "Connection: close", because the fsouza docker client
   expects the tcp socket to stay open between requests.

2) Because we cannot force-close the connection, we can't hijack the
   connection (because go's net/http doesn't let use un-hijack it).

3) Because we need to maintain the individual chunking of messages (for
   docker-py), we can't just copy the response body, as Go will remove and
   re-add the chunking willy-nilly.

Therefore, we have to read each chunk one-by-one, and flush the
ResponseWriter after each one.

Matthias Radestock 7ae06ef00d Merge pull request #1126 from weaveworks/issues/1018-more-flexible-hostname-derivation 
[proxy] More flexible container name -> hostname derivation

Closes #1018.

Tom Wilkie 8b061fd555 Gossip-based DNS embedded in the router. 
- Nameserver holds a sorted list of (hostname, peer, container id, ip) tuples.
- Entries are gossiped using topology gossip / broadcast - only new/updated entries
  are propogated as expected.
- Entries for a given peer are removed when the connection to the peer is lost.
- Entries are tombstoned when containers die.  Tombstones are kept for 10mins,
  as they do not need to survive partition, only gossip propagation delay.

Alfonso Acosta 4f82dc97fd [proxy] More flexible container name -> hostname derivation 
Provides to new two new flags: `--hostname-match <regexp>`
and `--hostname-replacement <replacement>`. When launching a container, its name
matched against regular expression `<regexp>`. Then, based on that match,
`<replacement>` will be used to generate a hostname, which will ultimately be
handed over to weaveDNS for registration.

The substitution is implemented with
https://golang.org/pkg/regexp/#Regexp.ReplaceAllString . Thus, references to
regexp substitution groups should be prepended with a dollar sign.

For instance, if we provide `--hostname-match '^aws-[0-9]+-(.*)$'` and
`--hostname-replacement 'my-app-$1'`, running a container named
`aws-12798186823-foo` through WeaveProxy will lead to WeaveDNS registering
`my-app-foo`.

Closes #1018

Paul Bellamy e4458372e8 [proxy] weavewait rewrites /etc/hosts so weave ip is returned first from 'hostname -i' 
Adds a --no-rewrite-hosts flag to the proxy, and be default, removes the
docker IP from hosts. We only discard the docker host when it exists, so
--net=none works.
