How to Run

  1. Find pods you'd like to tap to in your Kubernetes cluster
  2. Run mizu tap or mizu tap PODNAME
  3. Open browser on http://localhost:8899/mizu or as instructed in the CLI
  4. Watch the API traffic flowing
  5. Type ^C to stop

Examples

Run mizu help for usage options

To tap all pods in current namespace -

 $ kubectl get pods 
 NAME                            READY   STATUS    RESTARTS   AGE
 carts-66c77f5fbb-fq65r          2/2     Running   0          20m

 front-end-649fc5fd6-kqbtn       2/2     Running   0          20m
 ..

 $ mizu tap
 +carts-66c77f5fbb-fq65r
 +catalogue-5f4cb7cf5-7zrmn
 +front-end-649fc5fd6-kqbtn
 Web interface is now available at http://localhost:8899
 ^C

To tap specific pod

 $ kubectl get pods 
 NAME                            READY   STATUS    RESTARTS   AGE
 front-end-649fc5fd6-kqbtn       2/2     Running   0          7m
 ..

 $ mizu tap front-end-649fc5fd6-kqbtn
 +front-end-649fc5fd6-kqbtn
 Web interface is now available at http://localhost:8899
 ^C

To tap multiple pods using regex

 $ kubectl get pods 
 NAME                            READY   STATUS    RESTARTS   AGE
 carts-66c77f5fbb-fq65r          2/2     Running   0          20m
 catalogue-5f4cb7cf5-7zrmn       2/2     Running   0          20m
 front-end-649fc5fd6-kqbtn       2/2     Running   0          20m
 ..

 $ mizu tap "^ca.*"
 +carts-66c77f5fbb-fq65r
 +catalogue-5f4cb7cf5-7zrmn
 Web interface is now available at http://localhost:8899
 ^C

Configuration

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
You can always override the defaults or config file with CLI flags

To get the default config params run mizu config
To generate a new config file with default values use mizu config -r

Advanced Usage

Kubeconfig

It is possible to change the kubeconfig path using KUBECONFIG environment variable or the command like flag with --set kube-config-path=<PATH>.
If both are not set - Mizu assumes that configuration is at ${HOME}/.kube/config

Namespace-Restricted Mode

Some users have permission to only manage resources in one particular namespace assigned to them By default mizu tap creates a new namespace mizu for all of its Kubernetes resources. In order to instead install Mizu in an existing namespace, set the mizu-resources-namespace config option

If mizu-resources-namespace is set to a value other than the default mizu, Mizu will operate in a Namespace-Restricted mode. It will only tap pods in mizu-resources-namespace. This way Mizu only requires permissions to the namespace set by mizu-resources-namespace. The user must set the tapped namespace to the same namespace by using the --namespace flag or by setting tap.namespaces in the config file

Setting mizu-resources-namespace=mizu resets Mizu to its default behavior

For detailed list of k8s permissions see PERMISSIONS document

User agent filtering

User-agent filtering (like health checks) - can be configured using command-line options:

$ mizu tap "^ca.*" --set tap.ignored-user-agents=kube-probe --set tap.ignored-user-agents=prometheus
+carts-66c77f5fbb-fq65r
+catalogue-5f4cb7cf5-7zrmn
Web interface is now available at http://localhost:8899
^C

Any request that contains User-Agent header with one of the specified values (kube-probe or prometheus) will not be captured

Traffic validation rules

This feature allows you to define set of simple rules, and test the traffic against them. Such validation may test response for specific JSON fields, headers, etc.

Please see TRAFFIC RULES page for more details and syntax.

OpenAPI Specification (OAS) Contract Monitoring

An OAS/Swagger file can contain schemas under parameters and responses fields. With --contract catalogue.yaml CLI option, you can pass your API description to Mizu and the traffic will automatically be validated against the contracts.

Please see CONTRACT MONITORING page for more details and syntax.

Configure proxy host

By default, mizu will be accessible via local host: 'http://localhost:8899/mizu/', it is possible to change the host, for instance, to '0.0.0.0' which can grant access via machine IP address. This setting can be changed via command line flag --set tap.proxy-host=<value> or via config file: tap proxy-host: 0.0.0.0 and when changed it will support accessing by IP

Run in 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.

For more information please refer to DAEMON MODE

    Service Unavailable

    Hi, after installing mizu binary I run: mizu tap ".*" -A

    I can see the list of pods being tapped in the terminal. I get: Mizu is available at http://localhost:8899/mizu

    However when I try to open that I get: `{ "kind": "Status", "apiVersion": "v1", "metadata": {

    }, "status": "Failure", "message": "error trying to reach service: dial tcp 10.2.19.212:8899: i/o timeout", "reason": "ServiceUnavailable", "code": 503 } ` kubectl is correctly working on my box. I can also see the temporary mizu-collector pod running in the cluster.

    Is it a port forward issue?

  • Add `AF_PACKET` support

    Add `AF_PACKET` support

    This PR adds AF_PACKET support as the capture source. AF_PACKET is supported since Linux kernel version 2.2

    Adds AF_XDP support as the capture source. AF_XDP is supported since Linux kernel version 4.18

    Adds packet-capture config alongside tls config to set the capture source. Its default value is libpcap so Mizu uses libpcap as before by default. The possible values of packet-capture flag are;

    • af_xdp
    • af_packet
    • libpcap

    an input that's not valid falls back to libpcap without a panic.

    AF_PACKET has a lower drop rate when it's compared to libpcap.

  • No analysis button appears in the UI.

    No analysis button appears in the UI.

    Describe the bug

    As described on Analysis in Mizu an Analysis button should appear in the upper right corner of the UI/Mizu webpage. It never does so though. And yes I've waited for several minutes and tried in Edge, Google Chrome and Firefox. To no avail.

    To Reproduce Steps to reproduce the behavior:

    1. Run mizu tap -A --analysis or mizu tap --namespaces NAME_OF_THE_NAMESPACE --analysis
    2. Let mizu do its magic and sniff API traffic
    3. wait and see that the Analysis button do NOT appear

    Expected behavior That the Analysis button appears in the upper right corner.

    Add the ability to set the insertion filter into CLI

    Adds tap.insertion-filter field to the configuration of the CLI which allows you to set the insertion filter of Basenine.

    The value can be a string which is the filters itself:

    $ ./cli/bin/mizu__ tap -n sock-shop --set tap.insertion-filter=http
    

    or a path to a BFL file:

    $ ./cli/bin/mizu__ tap -n sock-shop --set tap.insertion-filter=/tmp/example.bfl
    

    example.bfl can be any filter. For example;

    Only inserts HTTP or AMQP traffic:

    http or amqp
    

    Only inserts when it's HTTP and the response status is 202:

    http and response.status == 202

  • Running mizu fails silently with no logs

    Running mizu fails silently with no logs

    Describe the bug A clear and concise description of what the bug is.

    To Reproduce Steps to reproduce the behavior:

    1. Run mizu tap or any variant of it which does NOT include mizu-resources-namespace and --namespaces
    2. See mizu terminate instantly with no logs or error output
    3. Run mizu tap --set mizu-resources-namespace=my-ns --namespaces=my-ns
    4. Mizu executes as expected
    5. Run mizu tap --set mizu-resources-namespace=mizu --namespaces=mizu
    6. See mizu terminate instantly with no logs or error output

    I'm admin on this cluster, and have even gone so far as to create the mizu namespace ahead of time after it failed originally.

    Expected behavior

    mizu tap command works without mizu-resources-namespace and --namespaces command

    Additional context Add any other context about the problem here.

    We do have an OPA policy which enforces a naming scheme on our namespaces unless a certain label is added. As such, I tried adding the mizu namespace manually with the partner: core label.

    Additionally, the mac install instructions don't add mizu to your path, so I manually copied it to /usr/local/bin/mizu though the issue was happening even when executing in my home directory with ./mizu instead of just mizu

    Is your feature request related to a problem? Please describe.

    Problem is our cluster has a policy not to allow latest tags. Setting tap.docker.tag: 37.0 produces and error since it tries to apply this tag to all components:

    Describe the solution you'd like to see

    Ideal solution is to be able to set container image tag in configuration per component, meaning hub, worker...with defaults to latest or change defaults to tag versions of all components per release.

    Downloaded CLI and when trying to tap into one of my namespaces, i'm getting this error from docker.

    I'm not sure what to do, i couldn't find any similar issue anywhere, so i assume im the only one facing this, and i'm not sure how to work around this. is there a way to configure docker credentials for the pull? because apparently it is not using my already logged account.
