Invalid kubectl #183

Open rcbarke opened 2 months ago

rcbarke commented 2 months ago

Following the O-RAN Near-Real Time RIC Installation Guide located here: https://openaicellular.github.io/oaic/oran_installation.html

The below script contains an issue with its kubernetes install: sudo ./k8s-1node-cloud-init-k_1_16-h_2_17-d_cur.sh

Dependencies: This script depends on curl being installed (sudo apt-get install curl)

Issue: During execution of the script kubectl will present several localhost:8080 connection refused errors When the script is stopped, kubectl cluster-info reveals that kubernetes is not properly installed

Resolution

  1. Attempt the process within the O-RAN Near-Real Time RIC Installation Guide until the connection refused errors are encountered. Halt the ./k8s-1node-cloud-init-k_1_16-h_2_17-d_cur.sh script.

  2. Install the latest K8S via https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/

    • Ensure to follow the instructions to install K8S in ~/.local/bin, not your local user directory

  3. Restart kubelet with sudo systemctl restart kubelet

  4. Retry sudo ./k8s-1node-cloud-init-k_1_16-h_2_17-d_cur.sh

  5. The connection refused errors will be gone, K8S pods will appropriately deploy, and the remaining instructions can be followed to setup influxDB and deploy the OAIC RIC

Important: Order of operations is pertinent here. If K8S is pre-installed before the OIAC installation script is run, the OAIC installation script will begin throwing different TCPIP errors stating localhost cannot be resolved. These appear to be due to an invalid ~/.kube/config

Where is the error within ./k8s-1node-cloud-init-k_1_16-h_2_17-d_cur.sh creating this behavior?

Just to note, containerizing this environment with docker would drastically simply this installation procedure.
