kubexp (KubeExplorer)

kubexp is a console user interface for kubernetes.

Features

• automatic update view when cluster changes
• switch cluster
• resource details and incremental search
• following container logs
• exec into container
• pod port-forward
• upload/download files to container
• scale deployments, replicasets etc.
• delete resources

Installation

You need a shell with access to kubernetes through kubectl. Kubexp uses the same configuration file (usually ~.kube/config) to connect to the k8s cluster(s).

rbac

Your service account must have a rolebinding to cluster admin in each k8s cluster. The file rbac-default-clusteradmin.yaml contains the according clusterrolebinding for the default service account:

kubectl apply -f rbac-default-clusteradmin.yaml

Option 1: get executable

Go to releases page and download the binary for your platform.

KUBEXP_RELEASE="0.9.0"
wget https://github.com/alitari/kubexp/releases/download/${KUBEXP_RELEASE}/kubexp
chmod +x kubexp

Option 2: running with docker

To run the kubexp container you need to mount the config file. Note, that when kubexp runs in a container the port-forward feature will not work.

KUBEXP_RELEASE="0.9.0"
docker run -it -v ~/.kube/config:/root/.kube/config alitari/kubexp:${KUBEXP_RELEASE}
