Issue/Introduction

The following steps are to be implemented in case users wish to use kubectl utility from a remote machine to access the VMware Telco Cloud ServiceAssurance cluster

Resolution

Please follow the steps below:

1) To Install kubectl binary with curl on Linux, download the kubectl latest release with the command:

# curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

2) (Optional) Validate the binary by downloading the kubectl checksum file:

# curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256"
# echo "$(cat kubectl.sha256) kubectl" | sha256sum --check

If valid, the output is:
kubectl: OK

If the check fails, sha256 exits with nonzero status and prints output similar to:
kubectl: FAILED
sha256sum: WARNING: 1 computed checksum did NOT match

Note: Ensure to download the same version of the binary and checksum.

 

3) Install kubectl

# sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

 

4) Test to ensure the version you installed is up-to-date:

# kubectl version --client

 

5) Export the TCSA deployment cluster configuration by setting the KUBECONFIG environment variable:

# export KUBECONFIG=<Path to the kubeconfig>
Example: export KUBECONFIG=/root/.kube/TCSA            #where TCSA is the kubeconfig name
