Weave
|
|
=======
|
|
|
|
Weave 2.0.1 is supported by kubespray
|
|
|
|
Weave be use with [**consensus**](https://www.weave.works/docs/net/latest/ipam/#initialization) mode (default mode) and [**seed**](https://www.weave.works/docs/net/latest/ipam/#initialization) mode
|
|
|
|
In kubespray, Weave encryption for all communication is supported
|
|
* For use Weave encryption, it's necessary to specify password
|
|
if no password specify, no encrytion
|
|
```
|
|
# In file ./inventory/group_vars/k8s-cluster.yml
|
|
weave_password: EnterPasswordHere
|
|
```
|
|
|
|
Weave is deploy by kubernetes with daemonSet
|
|
* Check the status of Weave containers
|
|
```
|
|
kubectl -n kube-system get pods | grep weave
|
|
```
|
|
* Check status of weave (connection,encryption ...)
|
|
```
|
|
curl http://127.0.0.1:6784/status
|
|
```
|
|
|
|
### Consensus mode (default mode)
|
|
This mode is to fixed cluster
|
|
|
|
### Seed mode
|
|
This mode is to dynamic cluster
|
|
|
|
the seed mode allows multi clouds simultaneously and also hybrid on premise/cloud clusters
|
|
* Change censensus mode to seed mode
|
|
```
|
|
# In file ./inventory/group_vars/k8s-cluster.yml
|
|
weave_mode_seed: true
|
|
```
|
|
This two variables are use to have automaticaly dynamic cluster (**/!\ do not manually change these values**)
|
|
```
|
|
# In file ./inventory/group_vars/k8s-cluster.yml
|
|
weave_seed: uninitialized
|
|
weave_peers: uninitialized
|
|
```
|
|
The first variable, `weave_seed`, allows to save the first or firsts node of the weave network
|
|
|
|
The seconde variable, `weave_peers`, allows to save IP of all node of the weave network
|
|
|
|
these two allows to connecte a new node to the weave network. this new node need to know the first node (seed) and list of IP to all node of network
|
|
|
|
For reset these variables set there values to `uninitialized` |
