Mizu daemon mode
Mizu can be run detached from the cli using the daemon flag: mizu tap --daemon
. This type of mizu instance will run
indefinitely in the cluster.
Please note that daemon mode requires you to have RBAC creation permissions, see the permissions doc for more details.
$ mizu tap "^ca.*" --daemon
Mizu will store up to 200MB of traffic, old traffic will be cleared once the limit is reached.

Stop mizu daemon
To stop the detached mizu instance and clean all cluster side resources, run mizu clean
$ mizu clean # mizu will continue running in cluster until clean is executed
Removing mizu resources
Expose mizu web app
Mizu could be exposed at a later stage in any of the following ways:
Using mizu view command
In a machine that can access both the cluster and a browser, you can run mizu view
command which creates a proxy.
Besides that, all the regular ways to expose k8s pods are valid.
$ mizu view
Establishing connection to k8s cluster...
Mizu is available at http://localhost:8899

Port Forward
$ kubectl port-forward -n mizu deployment/mizu-api-server 8899:8899
NodePort
$ kubectl expose -n mizu deployment mizu-api-server --name mizu-node-port --type NodePort --port 80 --target-port 8899
Mizu's IP is the IP of any node (get the IP with kubectl get nodes -o wide
) and the port is the target port of the new
service (kubectl get services -n mizu mizu-node-port
). Note that this method will expose Mizu to public access if your
nodes are public.
LoadBalancer
$ kubectl expose deployment -n mizu --port 80 --target-port 8899 mizu-api-server --type=LoadBalancer --name=mizu-lb
service/mizu-lb exposed
..
$ kubectl get services -n mizu
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
mizu-api-server ClusterIP 10.107.200.100 <none> 80/TCP 5m5s
mizu-lb LoadBalancer 10.107.200.101 34.77.120.116 80:30141/TCP 76s
Note that LoadBalancer
services only work on supported clusters (usually cloud providers) and might incur extra costs
If you changed the mizu-resources-namespace
value, make sure the -n mizu
flag of the kubectl expose
command is
changed to the value of mizu-resources-namespace
mizu will now be available both by running mizu view
or by accessing the EXTERNAL-IP
of the mizu-lb
service
through your browser.
