Bryan Boreham 2a04df1049 Rename "kube-peers" to "kube-utils" 
It's now doing things like network status that are outside of the
scope of "peers".

Martynas Pumputis 6dbe95a0b5 Add NO_MASQ_LOCAL to weave-kube/launch.sh 
One can enable the feature by setting NO_MASQ_LOCAL=1 among
env vars of the weave-kube DaemonSet.
 2018-06-04 14:08:24 +02:00
Martynas Pumputis ebf4b4b48a Implement and start using NoMasqLocalTracker 
The tracker updates the "no-masq-local" ipset with CIDR ranges allocated
by IPAM.
 2018-06-04 14:08:24 +02:00
Martynas Pumputis 62c30d9130 Extern LocalRangeTracker interface with String method 
Cleaner approach than passing a tracker name to ipam/http.
 2018-06-04 14:08:24 +02:00
Martynas Pumputis 21fb953d0f Create weave-no-masq-local ipset 
The ipset is used to track locally allocated CIDRs. If requested,
external traffic sent to pods within these CIDR ranges will
avoid SNAT'ing (NYI).
 2018-06-04 14:08:24 +02:00
Martynas Pumputis 27c98070e8 Move npc/ipset package to net/ipset

Martynas Pumputis 6dce685105 Merge remote-tracking branch 'origin/2.3' 2018-05-22 17:21:03 +02:00
Marc Carré 9f207f161a Add org.opencontainers.image.* labels to Dockerfiles 
- This should ultimately help for image-to-code back references.
- `org.label-schema.*` labels are now deprecated, in favour of `org.opencontainers.image.*` labels.
  See also: https://github.com/opencontainers/image-spec/blob/master/annotations.md#back-compatibility-with-label-schema
- Git revision is now injected at `docker build` time.

Bryan Boreham c2c14410d2 Remove subprocess for changing netns 
Now that Go 1.10 has removed the issue which made us do this.
 2018-04-30 23:40:59 +01:00
Bryan Boreham 672c770dbe Rework /report handler to pull format from URL 
Otherwise test 150 would fail - Gorilla mux was not handling a newline
in the format parameter.  This way you also get a better error if you
have an error in the parameter - instead of a 404.

Bryan Boreham e7f30106c0 Pass the WeaveDNS Domain into the proxy 
instead of obtaining it via the http api
 2018-01-29 15:55:36 +00:00
Bryan Boreham 86d2800b59 Make proxy use configured WeaveDNS address 
rather than assuming it is listening on the weave bridge
 2018-01-29 15:55:36 +00:00
Bryan Boreham e65006042d Remove obsolete --dns-effective-listen-address parameter 
it was needed when we ran inside a container network namespace
 2018-01-29 15:55:36 +00:00
Martynas Pumputis a0c8fc2ddb Pass WEAVE_NO_BRIDGED_FASTDP to weaver 2017-12-17 19:05:12 +01:00
Martynas Pumputis 1860f21efb Remove "create_bridge" routines 
No longer needed in the weave script and thus, in weaveutil.
 2017-12-16 21:19:25 +01:00
Martynas Pumputis 541adf6bb1 Make "weave attach" to depend on running weaver 
"weave attach $CIDR $CONTAINER_ID" is no longer possible w/o
running weaver. This feature was undocumented and complicated
the weave script, as "weave attach" required to call "create_bridge".
Removing the feature allows us to eliminate the bridge creation
from the script.

Running "weave attach" w/o weaver results in the following err:

    bridge "weave" not present; did you launch weave?

Also, this commit simplifies the "attach-container" cmd from
weaveutil by removing "mtu" as a param. The cmd is used
only by "weave attach", and a mtu is value for an attached
container interface is exactly the same as one of the weave bridge.

Shevchenko Vitaliy 12b4898b3d Add ability to set log level for net-plugin 2017-12-14 14:19:33 +02:00
Bryan Boreham d2ed91ccc8 Clean up log messages a bit 2017-12-01 14:20:39 +00:00
Bryan Boreham 333f4a1d3c Make sure Annotation names conform to Kubernetes requirements. 
E.g. replace "26:c6:0b:ba:fd:31" with "26_c6_0b_ba_fd_31"
 2017-12-01 14:20:39 +00:00
Bryan Boreham 832fe2f0b0 Update local copy of annotations even after error 
e.g. if we get a clash because someone else has updated the data, it
returns the new data so we should work off that next time.

Also re-fetch the Annotations every time round the main loop for safety.

Bryan Boreham f07238c8bb Move info log to after error check 2017-11-16 14:31:40 +00:00
Bryan Boreham 3b499ce27c Rearrange peer reclaim checks in weave-kube launch script 
This is to make it behave better on fresh start, and in the case where
the manifest has not been updated to give it permissions.

Bryan Boreham f0e511510a Don't print a message on flag not found 2017-11-15 12:35:19 +00:00
Bryan Boreham 570ab0b10b Avoid deleting persisted data on weave-kube upgrade 
Add a feature to weaveutil to get and set flags, then use this feature
to mark the DB when this version runs
 2017-11-15 11:26:43 +00:00
Bryan Boreham 214cf6cb2e Flip result code when checking for new peer 
This avoids mistaking an error condition for the result we should act on

Bryan Boreham 07459f0cec Merge pull request #3149 from weaveworks/fix-2797-loosing-ipam-ips

 2017-11-14 15:31:06 +00:00
Bryan Boreham c67bc704e1 Temporarily raise kube-peers log level to debug 2017-11-14 14:16:01 +00:00
Bryan Boreham 3501ad45e6 Cope with a Kubernetes node being deleted and coming back 
Add features to weaver and kube-peers to find the peer name and check
if it is in the list, then in launch.sh delete persisted data if not.
 2017-11-14 14:15:31 +00:00
Bryan Boreham 70a13c9c12 Make kube-peers logging consistent and add -log-level flag 
Also tag kube-peer log messages with "[kube-peers]": in a standard
deployment they end up interspersed with weaver log messages so this
makes it easier to pick them out.
