### Breaking Bad!

> ☢️ !!Prior to installing v0.30.0!! Please be sure to backup your k9s configs directories or move them somewhere safe!!

> ☢️ Please watch the v0.30.0 Sneak peek series (links below) for detailed information.
>
> ☢️ Most K9s configuration files have either split or changed location or names on this drop!!

> We recommend moving your current k9s config dirs to another location and start k9s from scratch and let it create and initialize the various configs
> to their new spec and location. You can then use your existing setup and patch with the new layout/spec.
> As of v0.30.0 all config files now use the `*.yaml` extension. We did our best to update all the docs to match the new version.
> If you find doc issues either file an issue or better yet submit a PR!

Some of you might say: `You're on the roll their bud! Two breaking changes drops in a row!!`
Per the wise words of my beloved Grand mama! `One can't cook a decent meal without creating a mess!`
Not to mention we're still at v0.x.y so `Open season on breaking changes` is very much in full effect.

Tho I have tested this drop quite a bit, there is a strong chance that I've broken some stuff.
The key here is to walk the fine line of improving k9s code base and features set with minimal impact to you.
As you know by now, I am committed to ease the pain and resolve issues quickly to get you all back up and running.

From the scope changes in this release, I would caution that this drop will likely break you!
If so, worry not! We will fix the duds so we are `Happy as a Hippo` once again.

There was a few issues with the way K9s persists it's configuration and various artifacts. So we rewrote it!
First and foremost all k9s related YAML resources, will now use the standard ".yaml" extension.
I think we've bloated the code checking for both extensions with no real actionable value!

As it stands the main K9s configuration `config.yml` will now be static. These settings are now readonly! All the dynamic configurations that K9s manages now live in a new directory aka `clusters`. The clusters directory manages your k8s cluster/context configurations. So things like active view, namespace, favorites, etc... now live in this directory. K9s configurations are still managed using either xdg `XDG_CONFIG_HOME` or you can set `K9S_CONFIG_DIR` to specify your preferred k9s configs location. Also all config files will now use the ".yaml" extension vs ".yml"!!

So the main k9s configuration (static) now looks like this:

```yaml
# $XDG_CONFIG_HOME/k9s/config.yaml
# File will be autogenerated with all the default fixins if not found in the config specification.
k9s:
  liveViewAutoRefresh: false
  refreshRate: 2
  maxConnRetry: 5
  readOnly: false
  noExitOnCtrlC: false
  ui: # NOTE! New level!!
    enableMouse: false
    headless: false
    logoless: false
    crumbsless: false
    noIcons: false
  skipLatestRevCheck: false
  disablePodCounting: false
  # ShellPod configuration applies to all your clusters
  shellPod:
    image: busybox:1.35.0
    namespace: default
    limits:
      cpu: 100m
      memory: 100Mi
  # ImageScan config changed from v0.29.0!
  imageScans:
    enable: false
    # Now figures exclusions ie excludes certain namespaces or specific workload labels
    exclusions:
      # Exclude the following namespaces for image vulscans!
      namespaces:
        - kube-system
        - fred
      # Exclude the following labels from image vulscans!
      labels:
        k8s-app:
          - kindnet
          - bozo
        env:
          - dev
  logger:
    tail: 100
    buffer: 5000
    sinceSeconds: -1
    fullScreenLogs: false
    textWrap: false
    showTime: false
  thresholds:
    cpu:
      critical: 90
      warn: 70
    memory:
      critical: 90
      warn: 70
```

Next context specific configurations that are managed by you and k9s live in the XDG data directory
i.e `$XDG_DATA_HOME/k9s/clusters` or `$K9S_CONFIG_DIR/clusters` if the env var is set.

```text
$XDG_DATA_HOME/k9s
// Clusters tracks visited kubeconfig cluster/contexts
├── clusters
│   ├── fred
│   │   └── bozo
│   │       └── config.yaml
│   ├── bozorg
│   │   ├── kind-bozo-1
│   │   │   └── config.yaml
│   │   ├── kind-bozo-2
│   │   │   └── config.yaml
│   │   └── kind-bozo-3
│   │       └── config.yaml
│   └── bumblebeetuna
│       └── blee
│           └── config.yaml
└── skins
    ├── black_and_wtf.yaml
    ├── dracula.yaml
    ├── in_the_navy.yml
    ├── ...
```

Now looking at a given context configuration i.e cluster-1/context-1/config.yaml

```yaml
# $XDG_DATA_HOME/k9s/clusters/bumblebeetuna/blee/config.yaml
k9s:
  cluster: bumblebeetuna
  readOnly: false # [New!] you can now single out a given context and make it readonly. Woof!
  skin: in_the_navy # [NEW!] you can also skin individual contexts. Woof Woof!
  namespace:
    active: all
    lockFavorites: false
    favorites:
    - all
    - kube-system
    - default
  view:
    active: dp
  featureGates:
    nodeShell: false
  portForwardAddress: localhost
```

Transient artifacts ie k9s logs, screen-dumps, benchmarks etc now live in the state config dir.

```text
$XDG_STATE_HOME/k9s
├── k9s.log # K9s log files
└── screen-dumps
    └── bumblebeetuna # Screen dumps location for context blee
        └── blee
            └── deployments-kube-system-1703018199222861000.csv
```

If you get stuck or if my instructions are just `clear as mud`... `k9s info` is always your friend!!

I feel this is an improvement (tho I might be unanimous on this!) especially for folks dealing with multi-clusters or swapping out there kubeconfigs...

> NOTE! Paint is still fresh on this deal. Proceed with caution and please help us flush this feature out!

# Got Prompt?

In this drop, we've also given the k9s command prompt aka `:xxx` some love.
You have the ability to specify filter directly in the prompt.

So for example, you can now run something like `:po /fred` to run pod view with a filter to just show pods containing `fred`. Likewise `:po k8s-app=fred,env=blee` to filter by labels.
And now for the`Krampus` special... you can see pods in a different context all together via `:pod @ctx-2`.
Finally you can combo and send the `whole enchilada` via `:po k8s-app=fred /blee ns-1 @ctx-x`
Did I mention with completion where applicable? Yes Please!!
Compliments of [Jayson Wang](https://github.com/wjiec). Be sure to thank him!!

Put these frequent flyers command in an alias and now you can nav your clusters with `even more style`!

# All Is Love?

🎵 `On The twentieth day of Christmas my true love gave to me... Ten workloads a-leaping??...` 🎵

This is a feature reported by many of you and its (finally!) here. As of this drop, we intro the `workload` view aka `wk` which is similar to `kubectl get all`. I was reluctant to intro it given the potential hazards on larger clusters but figured why not? YOLO. I think using it in combo with the prompt updates it could pack a serious punch to observe workload related artifacts.

# Vulnerability Scan Exclusions...

As it seems customary with all k9s new features, folks want to turn them off ;(
The `Vulscan` feature did not get out unscathed ;(
As it was rightfully so pointed out, you may want to opted out scans for images that you do not control.
Tho I think it might be a good idea to run wide open once in a while to see if your cluster has any holes??
For this reason, we've opted to intro an exclusion section under the image scan configuration to exclude certain images from the scans.

Here is a sample configuration:

```yaml
k9s:
  liveViewAutoRefresh: false
  refreshRate: 2
  ui:
    enableMouse: false
    headless: false
    logoless: false
    crumbsless: false
    noIcons: false
  imageScans:
    enable: true
    exclusions:
      # Skip scans on these namespaces
      namespaces:
        - ns-1
        - ns-2
      # Skip scans for pods matching these labels
      labels:
        - app:
          - fred
          - blee
          - duh
        - env:
          - dev
```

This is a bit of a blur now, but I think that it! We hope you guys will dig this drop or at least the concepts as likely this is going to be `Open Season` on bugs ;(

🎵 `On The second day of Christmas my true love gave to me... Eleven buggers bugging??...` 🎵

Lastly looks like the sponsorship stream is down to an alarming trickle so if you dig this project and find it useful be sure `to give til it hurts!`

🎅 Best wishes to you and yours for good health and happiness this holiday season!! 🎉

AndJoy!
