♫ Sounds Behind The Release ♭

I figured why not share one of the tunes I was spinning when powering thru teh bugs? Might as well share the pain/pleasure while viewing these release notes!

Our Release Heroes

Please join me in recognizing and applauding this drop contributors that went the extra mile to make sure K9s is better and more useful for all of us!!

Big ATTA BOY/GIRL! in full effect this week to the good folks below for their efforts and contributions to K9s!!

A Word From Our Sponsors...

First off I would like to send a Big Thank You to the following generous K9s friends for joining our sponsorship program and supporting this project!

Contrarily to popular belief, OSS is not free! We've now reached ~9k stars and 300k downloads! As you all know, this project is not pimped out by a big company with deep pockets and a big dev team. K9s is complex and does demand lots of my time. So if this tool is useful to you and your organization and part of your daily Kubernetes flow, please contribute! Your contribution whether financial, PRs, issues or shout-outs on social/blogs are crucial to keep K9s growing and powerful for all of us. Don't let OSS by individual contributors become an oxymoron!

Describe/YAML goes FullMonty!!

We've added a new option to enable full screen while describing or viewing a resource YAML. Similarly to the full screen toggle option in the log view, pressing f will now toggle full-screen for both YAML and Describe views.

Additionally, the YAML and Describe view are now reactive! YAML/Describe views will now watch for changes to the underlying resource manifests. I'll admit this was a feature I was missing, but decided to punt as it required a bit of re-org to make it happen correctly. So BIG thanks to Fabian-K for entering this issue and for the boost!!

Not cool enough for Ya? the YAML view now also affords for getting ride of those pesky managedFields while viewing a resource. Use the m key to toggle visibility on the managedFields.

Best Effort... Not!

In this drop, we've added 2 new columns namely CPU/R:L and MEM/R:L. These represents the current request:limit specified on containers. They are available in node, pod and container views. While in Pod view, you will need to volunteer them and use the Go Wide option Ctrl-W to see the columns. These columns will be display by default for Node/Container views. In the node view, they tally the total amount of resources for all pods hosted a given node. If that's inadequate, you can also leverage K9s Custom Column feature to volunteer them or not.

Set Container Images

You will have the ability to tweak your container images for experimentation, using the new SetImage binding aka i. This feature is available for un-managed pods, deployments, statefulsets and daemonsets. With a resource selected, pressing i will provision an edit dialog listing all init/container images. So you will have to ability to tweak the images and update your containers. Big Thanks to Antoine Méausoone for making this feature available to all of us!!

NOTE! This is a one shot commands applied directly against your cluster and won't survive a new resource deployment.

Crumbs On...Crumbs Off, Caterpillar

We've added a new configuCCration to turn off the crumbs via crumbsLess configuration option. You can also toggle the crumbs via the new key option Ctrl-g. You can enable/disable this option in your ~/.k9s/config.yml or via command line using --crumbsless CLI option.

k9s:
  refreshRate: 2
  headless: false
  crumbsless: false
  readOnly: true
  ...

BANG FILTERS!

Some folks have voiced the desire to use inverse filters to refine content while in resource table views. Appending a ! to your filter will now enable an inverse filtering operation For example, in order to see all pods that do not contain fred in their name, you can now use /!fred as your filtering command. If you dig this implementation, please make sure to give a big thank you to Michael Albers for the swift implementation!

New Conf On the Block...

In this release, we've made some changes to the retry policies when things fail on your cluster and the api-server is suffering from an hearing impediment. The current policy was to check for connection issues every 15secs and retry 15 times before exiting K9s. This rules were not configurable and could yield for overtaxing the api-server. So we've implemented exponential back-off so that K9s can attempt to remediate or bail out of the session if not.
To this end, there is a new config option namely maxConnRetry to will be added to your K9s config to set the retry policy. The default is currently set to 5 retries.

NOTE: This is likely an ongoing story and more will come based on your feedback!

Sample K9s configuration

k9s:
  refreshRate: 2
  # Set the maximum attempt to reconnect with the api-server in case of failures.
  maxConnRetry: 5
  ...

🏁 Start Your Engines...

As you can see, this is a pretty big drop and likely we've created some new issues in the process 🙀

Please make sure to file issues/PRs if things are not working as expected so we can improve on these features.

👻 Happy Halloween To All!! (as if 2020 is not scary enough 🙈)

Thank you all for your being fans and supporting K9s!!
