Weave
Weave 2.0.1 is supported by kubespray
Weave uses consensus mode (default mode) and seed mode.
Weave encryption is supported for all communication
- To use Weave encryption, specify a strong password (if no password, no encrytion)
# In file ./inventory/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 daemonSet
- Check the status of Weave containers
# From client
kubectl -n kube-system get pods | grep weave
- Check status of weave (connection,encryption ...) for each node
# On nodes
curl http://127.0.0.1:6784/status
- Check parameters of weave for each node
# On nodes
ps -aux | grep weaver
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 deployement.
- Switch from consensus mode to seed mode
# In file ./inventory/group_vars/k8s-cluster.yml
weave_mode_seed: true
These two variables are only used when weave_mode_seed is set to true (/!\ 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, saves the firsts nodes of the weave network
The seconde variable, weave_peers, saves IP of all nodes of the weave network
These two variables are used to connect a new node to the weave network. The new node needs to know the firsts nodes (seed) and the list of IPs of all nodes.
To reset these variables and reset the weave network set them to uninitialized
