EJFAT Node Initialization

This directory contains scripts for initializing JRMs on EJFAT nodes.

Key Files

  1. node-setup.sh: Sets up individual EJFAT nodes.
  2. launch-nodes.sh: Launches EJFAT nodes.

Step-by-Step Usage

EJFAT Node Initialization Flow Chart

1. Download the Repository

Clone the GitHub repository to your local machine: 

git clone https://github.com/JeffersonLab/jiriaf-test-platform.git
cd jiriaf-test-platform/main/local-ejfat/init-jrm

2. Set API Server Port

Check your Kubernetes configuration file at ~/.kube/config to find the correct API server port. Update the APISERVER_PORT in launch-nodes.sh to match this port.

3. Customize Node Selection

By default, the script initializes only ejfat-2. To change this:

  • Open launch-nodes.sh in a text editor.
  • Locate the line: for i in $(seq 2 2)
  • Modify the numbers to select different nodes. For example:
    • $(seq 1 3) initializes nodes 1, 2, and 3.
    • $(seq 5 7) initializes nodes 5, 6, and 7.

4. Prepare SSH Access, kubeconfig, and Docker

  • Ensure you have SSH access to the EJFAT nodes you intend to initialize.
  • Verify that Docker is installed and running on each EJFAT node. The script requires Docker to pull and run necessary images.

5. Copy kubeconfig file to EJFAT nodes

Copy the kubeconfig file to the EJFAT nodes:

For example, to copy to ejfat-2: 

scp ~/.kube/config ejfat-2:/home/jlabtsai/.kube/config

6. Run the Launch Script

Execute the launch-nodes.sh script: 

./launch-nodes.sh

Script Execution Process

For each selected node, the script will:

  • Set up an SSH tunnel for port forwarding.
  • Copy node-setup.sh to the target node.
  • Execute node-setup.sh on the node with appropriate parameters.

Wait for Completion

The script will wait for all node setup processes to complete.

Special Cases

Node 7 is treated as a special case and renamed to "fs". If you're including node 7, be aware of this naming convention in the script.

Troubleshooting

If you encounter issues:

  1. Verify SSH connectivity to the target nodes.
  2. Check if the API server port is available on both local and remote machines.
  3. Ensure node-setup.sh is present in the same directory as launch-nodes.sh.
