 ## Configuration
 
-Mizu can work with config file which should be stored in ${HOME}/.mizu/config.yaml (macOS: ~/.mizu/config.yaml) <br />
-In case no config file found, defaults will be used <br />
+Mizu can optionally work with a config file that can be provided as a CLI argument (using `--set config-path=<PATH>`) or if not provided, will be stored at ${HOME}/.mizu/config.yaml 
 In case of partial configuration defined, all other fields will be used with defaults <br />
 You can always override the defaults or config file with CLI flags
 
 To get the default config params run `mizu config` <br />
 To generate a new config file with default values use `mizu config -r`
 
-### Telemetry
-
-By default, mizu reports usage telemetry. It can be disabled by adding a line of `telemetry: false` in the `${HOME}/.mizu/config.yaml` file

+![Mizu: The API Traffic Viewer for Kubernetes](../assets/mizu-logo.svg)
+# Configuration options for Mizu
+
+Mizu has many configuration options and flags that affect its behavior. Their values can be modified via command-line interface or via configuration file. 
+
+The list below covers most useful configuration options.
+
+### Config file
+Mizu behaviour can be modified via YAML configuration file located at `$HOME/.mizu/config.yaml`. 
+
+Default values for the file can be viewed via `mizu config` command.
+
+### Applying config options via command line
+To apply any configuration option via command line, use `--set` following by config option name and value, like in the following example:
+
+```
+mizu tap --set tap.dry-run=true
+```
+
+Please make sure to use full option name (`tap.dry-run` as opposed to `dry-run` only), incl. section (`tap`, in this example)
+
+## General section
+
+* `agent-image` - full path to Mizu container image, in format `full.path.to/your/image:tag`. Default value is set at compilation time to `gcr.io/up9-docker-hub/mizu/<branch>:<version>`
+
+* `dump-logs` - if set to `true`, saves log files for all Mizu components (tapper, api-server, CLI) in a zip file under `$HOME/.mizu`. Default value is `false`
+
+* `image-pull-policy` - container image pull policy for Kubernetes, default value `Always`. Other accepted values are `Never` or `IfNotExist`. Please mind the implications when changing this.
+
+* `kube-config-path` - path to alternative kubeconfig file to use for all interactions with Kubernetes cluster. By default - `$HOME/.kubeconfig`
+
+* `mizu-resources-namespace` - Kubernetes namespace where all Mizu-related resources are created. Default value `mizu`
+
+* `telemetry` - report anonymous usage statistics. Default value `true`
+
+## section `tap`
+* `namespaces` - list of namespace names, in which pods are tapped. Default value is empty, meaning only pods in the current namespace are tapped. Typically supplied as command line options.
+
+* `all-namespaces` - special flag indicating whether Mizu should search and tap pods, matching the regex, in all namespaces. Default is `false`. Please use with caution, tapping too many pods can affect resource consumption.
+
+* `daemon` - instructs Mizu whether to run daemon mode (where CLI command exits after launch, and tapper & api-server pods in Kubernetes continue to run without controlling CLI). Typically supplied as command-line option `--daemon`. Default valie is `false`
+
+* `dry-run` - if true, Mizu will print list of pods matching the supplied (or default) regex and exit without actually tapping the traffic. Default value is `false`. Typically supplied as command-line option `--dry-run`
+
+* `proxy-host` - IP address on which proxy to Mizu API service is launched; should be accessible at `proxy-host:gui-port`. Default value is `127.0.0.1`
+
+* `gui-port` - port on which Mizu GUI is accessible, default value is `8899` (stands for `8899/tcp`)
+
+* `regex` - regular expression used to match pods to tap, when no regex is given in the command line; default value is `.*`, which means `mizu tap` with no additional arguments is runnining as `mizu tap .*` (i.e. tap all pods found in current workspace)
+
+* `no-redact` - instructs Mizu whether to redact certain sensitive fields in the collected traffic. Default value is `false`, i.e. Mizu will replace sentitive data values with *REDACTED* placeholder.
+
+* `ignored-user-agents` - array of strings, describing HTTP *User-Agent* header values to be ignored. Useful to ignore Kubernetes healthcheck and other similar noisy periodic probes. Default value is empty.
+
+* `max-entries-db-size` - maximal size of traffic stored locally in the `mizu-api-server` pod. When this size is reached, older traffic is overwritten with new entries. Default value is `200MB`
+ 
+
+### section `tap.api-server-resources`
+Kubernetes request and limit values for the `mizu-api-server` pod.
+Parameters and their default values are same as used natively in Kubernetes pods:
+
+```
+        cpu-limit: 750m
+        memory-limit: 1Gi
+        cpu-requests: 50m
+        memory-requests: 50Mi
+```
+
+### section `tap.tapper-resources`
+Kubernetes request and limit values for the `mizu-tapper` pods (launched via daemonset).
+Parameters and their default values are same as used natively in Kubernetes pods:
+
+```
+        cpu-limit: 750m
+        memory-limit: 1Gi
+        cpu-requests: 50m
+        memory-requests: 50Mi
+```
+
+
+--
+
+* `analsys` - enables advanced analysis of collected traffic in the UP9 coud platform. Default value is `false`
+
+* `upload-interval` -  in the *analysis* mode, push traffic to UP9 cloud every `upload-interval` seconds. Default value is `10` seconds
+
+* `ask-upload-confirmation` - request user confirmation when uploading tapped data to UP9 cloud
+
+
+## section `version`
+* `debug`- print additional version and build information when `mizu version` command is invoked. Default value is `false`.

+# 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.

+
+## Stop mizu daemon
+
+To stop the detached mizu instance and clean all cluster side resources, run `mizu clean`
+
+```bash
+$ 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.
+
+```bash
+$ mizu view
+  Establishing connection to k8s cluster...
+  Mizu is available at http://localhost:8899
+  ^C
+  ..
+```
+
+### Port Forward
+
+```bash
+$ kubectl port-forward -n mizu deployment/mizu-api-server 8899:8899
+```
+
+### NodePort
+
+```bash
+$ 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
+
+```bash
+$ 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.

+![Mizu: The API Traffic Viewer for Kubernetes](../assets/mizu-logo.svg)
+# Istio mutual tls (mtls) with Mizu
+This document describe how Mizu tapper handles workloads configured with mtls, making the internal traffic between services in a cluster to be encrypted.
+
+Besides Istio there are other service meshes that implement mtls. However, as of now Istio is the most used one, and this is why we are focusing on it.
+
+In order to create an Istio setup for development, follow those steps:
+1. Deploy a sample application to a Kubernetes cluster, the sample application needs to make internal service to service calls
+2. SSH to one of the nodes, and run `tcpdump`
+3. Make sure you see the internal service to service calls in a plain text
+4. Deploy Istio to the cluster - make sure it is attached to all pods of the sample application, and that it is configured with mtls (default)
+5. Run `tcpdump` again, make sure you don't see the internal service to service calls in a plain text 
+
+## The connection between Istio and Envoy
+In order to implement its service mesh capabilities, [Istio](https://istio.io) use an [Envoy](https://www.envoyproxy.io) sidecar in front of every pod in the cluster. The Envoy is responsible for the mtls communication, and that's why we are focusing on Envoy proxy.
+
+In the future we might see more players in that field, then we'll have to either add support for each of them or go with a unified eBPF solution.
+
+## Network namespaces
+A [linux network namespace](https://man7.org/linux/man-pages/man7/network_namespaces.7.html) is an isolation that limit the process view of the network. In the container world it used to isolate one container from another. In the Kubernetes world it used to isolate a pod from another. That means that two containers running on the same pod share the same network namespace. A container can reach a container in the same pod by accessing `localhost`.
+
+An Envoy proxy configured with mtls receives the inbound traffic directed to the pod, decrypts it and sends it via `localhost` to the target container.
+
+## Tapping mtls traffic
+In order for Mizu to be able to see the decrypted traffic it needs to listen on the same network namespace of the target pod. Multiple threads of the same process can have different network namespaces. 
+
+[gopacket](https://github.com/google/gopacket) uses [libpacp](https://github.com/the-tcpdump-group/libpcap) by default for capturing the traffic. Libpacap doesn't support network namespaces and we can't ask it to listen to traffic on a different namespace. However, we can change the network namespace of the calling thread and then start libpcap to see the traffic on a different namespace.
+
+## Finding the network namespace of a running process
+The network namespace of a running process can be found in `/proc/PID/ns/net` link. Once we have this link, we can ask Linux to change the network namespace of a thread to this one.
+
+This mean that Mizu needs to have access to the `/proc` (procfs) of the running node.
+
+## Finding the network namespace of a running pod
+In order for Mizu to be able to listen to mtls traffic, it needs to get the PIDs of the the running pods, filter them according to the user filters and then start listen to their internal network namespace traffic.
+
+There is no official way in Kubernetes to get from pod to PID. The CRI implementation purposefully doesn't force a pod to be a processes on the host. It can be a Virtual Machine as well like [Kata containers](https://katacontainers.io)
+
+While we can provide a solution for various CRIs (like Docker, Containerd and CRI-O) it's better to have a unified solution. In order to achieve that, Mizu scans all the processes in the host, and finds the Envoy processes using their `/proc/PID/exe` link.
+
+Once Mizu detects an Envoy process, it need to check whether this specific Envoy process is relevant according the user filters. The user filters are a list of `CLUSTER_IPS`. The tapper gets them via the `TapOpts.FilterAuthorities` list.
+
+Istio sends an `INSTANCE_IP` environment variable to every Envoy proxy process. By examining the Envoy process's environment variables we can see whether it's relevant or not. Examining a process environment variables is done by reading the `/proc/PID/envion` file.
+
+## Edge cases
+The method we use to find Envoy processes and correlate them to the cluster IPs may be inaccurate in certain situations. If, for example, a user runs an Envoy process manually, and set its `INSTANCE_IP` environment variable to one of the `CLUSTER_IPS` the tapper gets, then Mizu will capture traffic for it.
