kubeconfig-merger is a command-line tool that concatenates two Kubernetes configuration files (kubeconfig files) into a single file. The resulting file can be used as a single kubeconfig file to manage multiple Kubernetes clusters.
To use kubeconfig-merger, you must have Go version 1.16 or later installed on your system. You can download Go from the official website: https://golang.org/dl/
You can download a pre-compiled release of kubeconfig-merger from the release page. Select the latest release and download the binary for your operating system.
Once you have downloaded the binary, you can use it directly without needing to compile the code.
-
Clone this repository:
git clone https://github.com/QJoly/kubeconfig-merger
-
Change to the directory where the repository was cloned:
cd kubeconfig-merger -
Compile the Go code into an executable binary:
go build -o kubeconfig-merger main.go
This will create an executable binary named
kubeconfig-mergerin the current directory.
To use kubeconfig-merger, run the executable binary with the following command:
./kubeconfig-merger <first-file> <second-file>
Replace <first-file> and <second-file> with the names of the two kubeconfig files you want to concatenate.
For example, if you have two kubeconfig files named kubeconfig-1.yaml and kubeconfig-2.yaml, you can concatenate them into a single file named combined-kubeconfig.yaml with the following command:
./kubeconfig-merger kubeconfig-1.yaml kubeconfig-2.yaml
The concatenated kubeconfig file will be saved as combined-kubeconfig.yaml in the current directory.
The purpose of kubeconfig-merger is to simplify management of multiple Kubernetes clusters by allowing you to use a single kubeconfig file to access them all. By concatenating multiple kubeconfig files into a single file, you can avoid the need to switch between different kubeconfig files when working with different clusters. This can make it easier to manage and automate Kubernetes operations.
