kubeconfig-merge: Painless and faultless way to merge kubeconfig files


release Code Coverage build go

Why is it developed?

If you are someone who works with a significant number of Kubernetes clusters, dealing with kubecontext in a manual way can be boring and also result in problems. In addition to that, I am currently working with more than 20 customers, which results in an average of five clusters per customer.

Install

Install on Linux

The following instruction list covers all of the Linux distributions (Ubuntu, Debian, Redhat, CentOS, RHEL, etc.) that provide sh as an executable:

(
    set -x
    EXEC_PATH="/usr/local/bin/kubeconfig-merge"
    cd "$(mktemp -d)" &&
        OS="$(uname | tr '[:upper:]' '[:lower:]')" &&
        ARCH="$(uname -m | sed -e 's/x86_64/amd64/' -e 's/\(arm\)\(64\)\?.*/\1\2/' -e 's/aarch64$/arm64/')" &&
        FILENAME="kubeconfig-merge_${OS}_${ARCH}" &&
        curl -fsSLO "https://github.com/btungut/kubeconfig-merge/releases/latest/download/${FILENAME}" &&
        sudo rm -rf "$EXEC_PATH" && sudo cp "${FILENAME}" "$EXEC_PATH" && sudo chmod +x "$EXEC_PATH"
)

Install on Windows

TBD
