Bryan Boreham c2c14410d2 Remove subprocess for changing netns 
Now that Go 1.10 has removed the issue which made us do this.

Martynas Pumputis 1860f21efb Remove "create_bridge" routines 
No longer needed in the weave script and thus, in weaveutil.

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

Martynas Pumputis ade6738789 Handle "weave expose" in weaver 
The change makes "weave expose" to call the "/expose" HTTP
endpoint implemented in router which exposes the bridge.

Such architectural change required as we need to know whether NPC is
enabled when exposing the bridge and weaver knows this fact the best.

Unfortunately, this change makes impossible to "weave expose"
when weaver is not running.

David Shepherd 8bf08c3cf8 Remove docker binary from weaveexec container 
Fixes #2957

- replace `docker stop` with `weaveuitl stop-container`
- replace `docker kill` with `weaveutil kill-container`
- replace `docker rm` with `weaveutil remove-container`
- replace `docker run` with minimal `weaveutil container-run`
- replace `docker inspect -f {{.ID}}` with `weaveutil container-id`
- replace data-only container `docker create` with `weaveutil create-volume-container`
- remove `docker inspect` dependencies from `weave` script
  `rewrite_etc_hosts` and `with_container_fqdn`
- rework `weave` script `check_running` and `check_not_running` to use `weaveutil`
- rework `weave version` to use `weaver` /report API or `weaver --version` if not running
- rework `weave setup`'s `docker pull` to run locally rather than in `weaveexec` container

Bryan Boreham 28aa181480 Move setting up addresses for a container, into weaveutil-invoked function 
This means we only change netns by execing nsenter: changing netns in
Go is unsafe for long-running processes like the proxy.
 2017-06-16 13:19:08 +00:00
Bryan Boreham edbf85655a Move rewrite /etc/hosts from shell to Go 2017-05-12 06:56:52 +00:00
Martynas Pumputis d5d45de5a4 Get rid of ipam modes in plugin-v2 
plugin-v2 is not going to be used with Docker IPAM in most cases,
so there is no need to complicate the code with ipam mode selection.
 2017-05-05 17:25:17 +00:00
Bryan Boreham d2cbb2749e Move plugin network creation from shell script to Go 
In the process, use the default subnet instead of the whole IP
allocation range.

Bryan Boreham 108f4784a6 Add back check for datapath supported 2017-04-20 16:12:42 +00:00
Bryan Boreham 3574da267b Remove -enforce_docker_bridge_addr_assign_type no longer used 2017-04-17 19:41:47 +00:00

Bryan Boreham 8051f51d46 Move bridge-creation code from weave script into Go code 
via weaveutil create-bridge function
 2017-04-17 19:41:47 +00:00
Martynas Pumputis 0ff37d3492 Do "docker plugin inspect" inside weaveutil 
We cannot do it from weaveexec, because the latter is distributed
with an old version of Docker client which does not support
Plugins API.
 2017-04-12 13:05:40 +00:00
Martynas Pumputis 82b56848a9 Add peer discovery for Docker Swarm 
The peer discovery relies on "GET /info" API call which returns
list of master nodes. The peer list is passed to weaver when
launching it.

If node is a master, then we pass "--ipalloc-alloc
consensus=$(MASTER_NODES_COUNT)" to weaver. Otherwise, we pass
"--ipalloc-alloc observer".

Martynas Pumputis ceb0186f46 Better error reporing for weaveutil 
If a weaveutil subcmd is not found, report the fact to stderr.

Martynas Pumputis cdd6ed548c Add netdev subcommands to weaveutil 
The subcommands are going to be used with WithNetNS wrapper.
 2016-10-19 16:07:53 +01:00
Martynas Pumputis 4a49ff3083 Replace usage of WithNetNSUnsafe in plugin/net/watcher.go with safer version 
Unsafe version was in ConfigureARPforVeths; replacement is via `weaveutil configure-arp`
 2016-10-06 15:25:05 +01:00
Bryan Boreham 50a8dc1383 Add weaveutil process-addrs 
Fetches addresses for every veth that is in a network namespace and
attached to the specified bridge.  Works by iterating over every process.
 2016-09-29 14:16:05 +01:00
Martynas Pumputis 24d9a00f47 Add check-datapath to weaveutil 
The utility is used to check whether a datapath can be created.

Matthias Radestock 31b303a419 move plugin network creation into weaveutil 
Note that we remove the ability to set the weavemesh network name, or
disabling it altogether. This was always poorly support, since the
removal operation only ever operated on the default name. The option
was also not listed in the usage, though it was in the docs.
 2016-01-15 08:52:57 +00:00
Matthias Radestock 9578798ec0 move plugin network removal into weaveutil 
This does require starting containerised weaveutil with docker.sock
volume mounts.
 2016-01-15 07:58:21 +00:00
Matthias Radestock 419f2ff71b move fastdp helpers into weaveutil 
so the weave script can invoke them w/o having to run a container
 2016-01-02 14:00:44 +00:00
Matthias Radestock 4ebcd355f6 move docker_tls_args into weaveutil 
and also give users a clue what went wrong when docker isn't running
