# Weave
|
||||
|
||||
Weave 2.0.1 is supported by kubespray
|
||||
|
||||
Weave uses [**consensus**](https://www.weave.works/docs/net/latest/ipam/##consensus) mode (default mode) and [**seed**](https://www.weave.works/docs/net/latest/ipam/#seed) mode.
|
||||
|
||||
`Consensus` mode is best to use on static size cluster and `seed` mode is best to use on dynamic size cluster
|
||||
|
||||
Weave encryption is supported for all communication
|
||||
|
||||
* To use Weave encryption, specify a strong password (if no password, no encryption)
|
||||
|
||||
```ShellSession
|
||||
# In file ./inventory/sample/group_vars/k8s_cluster.yml
|
||||
weave_password: EnterPasswordHere
|
||||
```
|
||||
|
||||
This password is used to set an environment variable inside weave container.
|
||||
|
||||
Weave is deployed by kubespray using a daemonSet
|
||||
|
||||
* Check the status of Weave containers
|
||||
|
||||
```ShellSession
|
||||
# From client
|
||||
kubectl -n kube-system get pods | grep weave
|
||||
# output
|
||||
weave-net-50wd2 2/2 Running 0 2m
|
||||
weave-net-js9rb 2/2 Running 0 2m
|
||||
```
|
||||
|
||||
There must be as many pods as nodes (here kubernetes have 2 nodes so there are 2 weave pods).
|
||||
|
||||
* Check status of weave (connection,encryption ...) for each node
|
||||
|
||||
```ShellSession
|
||||
# On nodes
|
||||
curl http://127.0.0.1:6784/status
|
||||
# output on node1
|
||||
Version: 2.0.1 (up to date; next check at 2017/08/01 13:51:34)
|
||||
|
||||
Service: router
|
||||
Protocol: weave 1..2
|
||||
Name: fa:16:3e:b3:d6:b2(node1)
|
||||
Encryption: enabled
|
||||
PeerDiscovery: enabled
|
||||
Targets: 2
|
||||
Connections: 2 (1 established, 1 failed)
|
||||
Peers: 2 (with 2 established connections)
|
||||
TrustedSubnets: none
|
||||

|
||||

|
||||
DefaultSubnet: 10.233.64.0/18
|
||||
```
|
||||
|
||||
* Check parameters of weave for each node
|
||||
|
||||
```ShellSession
|
||||
# On nodes
|
||||
ps -aux | grep weaver
|
||||
# output on node1 (here its use seed mode)
|
||||

|
||||
```
|
||||
|
||||
## Consensus mode (default mode)
|
||||
|
||||
This mode is best to use on static size cluster
|
||||
|
||||
### Seed mode
|
||||
|
||||
This mode is best to use on dynamic size cluster
|
||||
|
||||
The seed mode also allows multi-clouds and hybrid on-premise/cloud clusters deployment.
|
||||
|
||||
* Switch from consensus mode to seed/Observation mode
|
||||
|
||||
See [weave ipam documentation](https://www.weave.works/docs/net/latest/tasks/ipam/ipam/) and use `weave_extra_args` to enable.
