Kube Forwarder watches for connection status and always tries reconnect on failure
Multiple clusters support
Bookmark and forward Kubernetes services from multiple clusters easily like never before
Use import and export functionality to share bookmarked services with your team or simply backup it
Zero native dependencies
Use port-forwarding without installing kubectl and avoid explanations to developers on how to use it
Add a cluster(s)
Before you start forwarding internal resources to your local machine, you have to add cluster configuration. To do this we have 3 different options in the app:
- Auto-detection of ~/.kube/config file and parsing settings from it
- Manual adding of Kubernetes config by selecting a file(s)
- Manual adding of Kubernetes config by pasting a text
- Import of the JSON file that could be generated via Kube Forwarder export functionality
When you add a new cluster via auto-detection (option 1) or manually using a file(a) selection (option 2), we could parse configs and if there are multiple contexts inside we will suggest you to add multiple clusters to the app. Few examples of yaml files we expect to have you could find there
Also, you could add a cluster by filling a form manually (option 3). The form has the following fields:
Name - the name of a cluster withing Kube Forwarder app.
Storing method (Set destination to your kube config or paste it as a text) - the method of storing a config It has two options:
Set a path- storing a path to the config file. It will be read every time when you forwarding a port. It allows a user to don't do any changes in Kube Forwarder's settings when a third-party app updates the config file. For example, when
azure-cliupdates an access token (#13).
Paste as a text- storing a config just as a yml text.
Path (if storing method is
Set a path) - the path to a config file.
Content (if storing method is
Paste as a text) - Yml config as a text.
Current Context (if storing method is
Set a path) - When you use
Set a path, you must select a context from a file which will be used to connect to a resource. Let's see an example of a problem that the field solves.
- Let's say we don't have
- A user has a config file with two contexts:
current-contextin the yml file is
- The user configured a cluster in Kube Forwarder with
Set a pathoption.
- The user created a resource
postgresand successfully forwarded ports for some time.
- Then the user executed
kubectl config use-context remote-cluster
- If the user tries to forward the resource in Kube Forwarder again, most likely there will be an error
since a connection will be established with
local-clusteras the user expected, and
So, to avoid the error we should store the current context in a separate field.
- Let's say we don't have
Add a resource
Kube Forwarder supports forwarding of all types of resources that supported by
kubectl – Pod, Deployment, Service.
We ask you to fill the form with the following fields:
Cluster Name - pick a cluster from one of the added clusters.
Namespace - the namespace of the resource you plan to forward.
Kind – pick one of the options Pod, Deployment or Service.
Name - name of the Pod, Deployment or Service.
Alias - alternative name of the resource that will be displayed on the homepage(optional)
Port Forwarding - Fill two fields. Local port - port from your local machine where the resource will be forwarded. Resource port - port of the resource from the Kubernetes cluster
Kube Forwarder allows you export cluster configuration in JSON that you could use to share with your team members or for the backup purpose. You could easily store it on Github. When you export cluster, you could export it with or without confidential information.

Fork Kube Forwarder repository (https://github.com/pixel-point/kube-forwarder/fork)
# Clone source code git clone https://github.com/<your-username>/kube-forwarder # install dependencies npm install # prepare .env files cp .env.example .env cp .env.example .env.production # serve with hot reload in Electron Dev app npm run dev # serve WEB version with hot reload at localhost:9081 npm run web
Build an application for production
# Build a target for current OS npm run build # Build a target for Windows npm run build -- -- --win # Build a target for Linux npm run build -- -- --linux # You can mix targets npm run build -- -- --win --linux # You can build static and target separately npm run build:dist npm run build:target -- --win

Running the tests
We are using Cypress to run integration tests. There are visual regression tests. It's important to run them inside docker container to get same screenshots as in Drone CI.
npm run test:cypress
Or you can run it manually on a local machine.
# Run the web version to test it npm run web # Run this command in a separate terminal tab npm run test:cypress:onhost # Or you can open Cypress GUI npm run test:cypress:open
Also, this steps could be used to configure CI environment.
