Menu Bar App for Managing Kubernetes Contexts on Mac

KubeContext

A small menu bar app for managing Kubernetes contexts.

• Easily switch between contexts
• Import/export contexts from/to kubeconfig files
• Context name in menu bar
• Assign colors to your contexts
• Easy context management UI for renaming context, setting namespace and more.

Installation

• Install from Mac App Store

• Install using Homebrew package manager: brew install --cask kubecontext

• Download from Releases

Please note: App Store version offers pro features as IAP, however other installation options bring all features as unlocked and free ;)

kubecontext's Issues

Bug after using minikube to set context

I get this alert after using minikube to set the context

Could not parse config file 
typeMismatch(Yams.Node.Mapping, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "clusters", intValue: nil), _YAMLCodingKey(stringValue: "Index 9", intValue: 9), CodingKeys(stringValue: "cluster", intValue: nil), CodingKeys(stringValue: "extensions", intValue: nil)], debugDescription: "Expected to decode Mapping but found Node instead.", underlyingError: nil))

if config file deleted app raises error

Hi there,

when I load a config from eg. my desktop, imported it and then delete it from my desktop, this error message appears, and makes the app stop. (not able close the app nor change the context:'

Could not parse config file 
Error Domain=NSCocoaErrorDomain Code=260 "The file “civo.txt” couldn’t be opened because there is no such file." UserInfo={NSFilePath=/Users/jan/Desktop/civo.txt, NSUnderlyingError=0x600002969860 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

It would be good, when the app, changes to some default context or asks for a new file.

Feature Request: Handling multiple config files

Hi turkenh,

your tool looks quite cool, but unfortunately I do have multiple kubeconfig files that I would like to use.
Basically I split the config files by customer, and merging them together would make them quite messy.

On the commandline, I can use the KUBECONFIG environment variable to merge these files and they work fine with kubectl, kubectx, lens,...

my directory structure (~/.kube/config.d in my case) would look like:

$ ls -1
00_preferences
customer_1
customer_2
customer_3
private_cluster

The preferences file is basically being used to hold the current context and global preferences, the other files look like normal kubeconfig files:

apiVersion: v1
kind: Config
contexts:
- name: customer1-develop
  context:
    cluster: customer1-develop
    user: 5nafu@customer1
- name: customer1-production
  context:
    cluster: customer1-production
    user: 5nafu@customer1
- name: test@customer1-develop
  context:
    cluster: customer1-develop
    user: test@customer1

clusters:
- name: customer1-develop
  cluster:
    server: https://<URL redacted>
- name: customer_1-production
  cluster:
    server: https://<URL redacted>

users:
- name: 5nafu@customer1
  user:
    token: <TOKEN redacted>
- name: test@customer1
  user:
    token: <TOKEN redacted>

It would be great if KubeContext could support this kind of multiple files structure.

Context icon color doesn't work in Big Sur

Changing to custom icon colors in the Manage Contexts view always defaults the text to black. This is a regression for Big Sur.

License Needed

Can you add a license so we know how we can use this code?

Kubeconfig file is growing with usage - while importing/removing contexts

When a context is deleted, KubeContext only removes respective context from contexts and does not remove the cluster or the user that the context uses. This causes a growing kubeconfig file with orphaned clusters and users.

namespaces with numbers fail

when namespaces are a number (e.g. "namespace":"973585995"), the quotes around the config are removed after changing contexts using KubeContext

kube config before using KubeContext

contexts:
- context:
    cluster: somecluster
    namespace: "973585995"
    user: someuser
  name: somename

kube config after using KubeContext

contexts:
- context:
    cluster: somecluster
    namespace: 973585995
    user: someuser
  name: somename

resulting in the following error:

$ kubectl config get-contexts

error: Error loading config file "/Users/mark/.kube/config": v1.Config.Contexts: []v1.NamedContext: v1.NamedContext.Context: v1.Context.Namespace: ReadString: expects " or n, but found 9, error found in #10 byte of ...|mespace":973585995,"|..., bigger context ...|ext"},{"context":{"cluster":"somecluster","namespace":973585995,"user":"someuser"},"name":"somename"},{"c|...

Feature request: Is the environment healthy

Would like to get the status of all the deployments,
If no deployments are failing or currently deploying turn the icon Green, otherwise turn it Yellow

I use extensively skaffold for development and have to constantly switch between the terminal and the project I am working on. Since I have to monitor the state of the cluster as I develop.

This seem like a no-brainer but its something that I have not found anywhere else. Alternatively it would be nice to add a how to compile guide and I can look into adding this feature myself

Does kubecontext support Linux? Can I package it to Linux?

Could not parse selected kubeconfig file - typeMismatch

Version 1.05 from the App Store

When selecting the kubeconfig file:

Could not parse selected kubeconfig file
 typeMismatch(Yams.Node.Sequence, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "users", intValue: nil), _YAMLCodingKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "user", intValue: nil), CodingKeys(stringValue: "exec", intValue: nil), CodingKeys(stringValue: "env", intValue: nil)], debugDescription: "Expected to decode Sequence but found Node instead.", underlyingError: nil))

Start on Login

Hi, I can't find the setting option to make this start when I boot / login, is that available anywhere?

Feature: Have a possibility to switch context with 2 clicks

Hi. I love the tool.
But I think it would be very cool if you could select the context immediately and you would not have to click Switch Context every time to do that :)
Cheers.

Giving name after importing the kubeconfig

It would be nice if we could give name to the config right after we used "Import Kubeconfig File" on menu bar.

Exporting Functinality

After importing kubeconfigs, I don't really keep track of them but when I need to share with someone else, it's really hard to find the file again. Could we have an export functionality that we can just choose a context and export it?

Could not parse kubeconfig file - keyNotFound

Hi,

first of all great idea! :)

However, after installing and configuring the kubeconfig file I get the following error message:

Could not parse selected kubeconfig file
 keyNotFound(CodingKeys(stringValue: "env", intValue: nil), Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "users", intValue: nil), _YAMLCodingKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "user", intValue: nil), CodingKeys(stringValue: "exec", intValue: nil)], debugDescription: "No value associated with key CodingKeys(stringValue: \"env\", intValue: nil) (\"env\").", underlyingError: nil))

Here the config file:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: <cert>
    server: https://<id>.sk1.us-east-1.eks.amazonaws.com
  name: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
contexts:
- context:
    cluster: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
    user: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
  name: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
current-context: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
kind: Config
preferences: {}
users:
- name: arn:aws:eks:us-east-1:<account-id>:cluster/test2-blub
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      args:
      - token
      - -i
      - test2-blub
      command: aws-iam-authenticator

In case this is relevant: the config file is generated by aws eks update-kubeconfig --name.
Any idea how to fix this? :)

malicious software

Does anyone is getting this “KubeContext.app” can’t be opened because Apple cannot check it for malicious software.
This software needs to be updated. Contact the developer for more information.
