=== This page is an index of the various docs and guides hosted on this site that will help manage and maintain a Chainlink Node. Please feel free to contact us with suggestions or if you'd like to contribute. ===

==== Accessing Chianlink Node CLI ====
The purpose of this page is to provide an index of content made available to you on this wiki.
Many of the  tasks on this page require you to have access to the Chianlink Node's CLI.


To access the CLI, you must attach to your Chainlink container's bash tty session
This content is either not indexed elsewhere, or does not exist outside of this wiki.


<code>docker exec -it $CONTAINER_NAME /bin/bash</code>

=== '''Environment Variable Details''' ===


Once connected, for the majority of the tasks you will want to accompish, you'll need to authenticate via your API credentials (the same credentials you use to access the web UI)


<code>chainlink admin login</code>
When you deploy a Chainlink Node, you need to create a .env file to include in your container's instantiation.


The purpose of this file is to override the default configuration your Chainlink node would set without it.


Now that you've authenticated with your API credentials, we can accomplish some more nuanced tasks that are not available via the web UI.

These wallets are responsible for paying the transaction fees associated with writing data on-chain for each network.

In some situations, you may find yourself in need of importing your own keys, or perhaps you've gotten a borked node and want to export your old keys and import them into a newly built Chainlink node.
The purpose of your OCR keys is to enable OCR communication between the nodes.


Whatever your situation, the steps below will assist
Each Chainlink node has their own OCR keys.  Modifying these keys in any manner is not suggested.


==== '''Key Format''' ====
==== '''P2P Keys''' ====
In order for your keys to be accepted for use in the Chainlink node, they must be in the proper, single line, json format.

Chainlink Node Account Private Keys

The Chainlink Node manages its own wallet's private keys keys for each network type it supports. At the time of this writing, that includes Layer One and Layer Two EVM chains, Solana, and Terra.

These wallets are responsible for paying the transaction fees associated with writing data on-chain for each network.

CSA Keys

The purpose of the CSA keys is for an unreleased feature. No more details can be provided at this time.

OCR Keys

The purpose of your OCR keys is to enable OCR communication between the nodes.

Each Chainlink node has their own OCR keys. Modifying these keys in any manner is not suggested.

P2P Keys

Similar to the OCR keys, the P2P keys enable peer to peer communication among the Chainlink Nodes

VRF Keys

The VRF Keys are specifically for the VRF functionality. No more details are available at this time.
