== Chainlink Node Management Index ==


=== 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. ===
== [[File:Index.png|left|frameless|30x30px]] '''Node Management Index''' ==


==== 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.

== '''Exporting Your Private Keys''' ==
----
If you'd like to export your private keys, the following steps will provide you with directions and examples
[[File:Construction.png|left|frameless|30x30px]]
=== '''Job Management''' ===
Chainlink Nodes require jobs in order for them to know what is expected of them.


While connected to, and authenticated with, the Chainlink CLI, we will want to:
==== '''Example JobSpecs''' ====
Below you will find example jobspecs for each job type that the Chainlink Node Supports


# List our keys to identify which one(s) we wish to export.
===== '''Direct Request Example''' =====
# Create a file containing our password used to encrypt the exported password.
Please click above to navigate to Direct Request (DR) / RunLog (RL) example spec
# Export our password.
# Copy the private key file to our host.


In the below example, we will be exporting an Ethereum mainnet private key.
===== '''FluxMonitor Example''' =====
Please click above to navigate to FluxMonitor (FM) example spec


==== '''List our keys to identify which one(s) we wish to export.''' ====
===== '''Off Chain Reporting Example''' =====
<code>chainlink keys eth list</code>
Please click above to navigate to Off Chain Reporting (OCR) example spec


====  '''Create a file containing our password used to encrypt the exported password.''' ====
<code>echo "$YOURPASSWORD" > passwordFile</code>


====  '''Export our password.''' ====
<code>chainlink keys eth export $0xKEY_ADDRESS --newpassword passwordFile --output $NAME_FOR_PRIAVTEKEY_FILE</code>


====  '''Copy the private key file to our host.''' ====
----
<code>docker cp $CONTAINER_NAME:/$NAME_FOR_PRIVATEKEY_FILE /host/path/$NAME_FOR_PRIVATEKEY_FILE</code>
[[File:Bridge.png|left|frameless|30x30px]]
=== '''Bridge Management''' ===
Chainlink Nodes use bridges to enable a key:value association local to the Chainlink Node.


Now that the file is on your Docker host, you can scp it somewhere else, or whatever you'd like to do with it.
This enables the node operator to modify where a bridge points to without having to redeploy every job that references that data source


==== '''Adding / Replacing / Removing Bridges''' ====
This page will provide directions on managing your bridges and all potential "gotchas" that you may run into


== '''Importing/Replacing Your Private Keys''' ==
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.


Whatever your situation, the steps below will assist


==== '''Key Format''' ====
----
In order for your keys to be accepted for use in the Chainlink node, they must be in the proper, single line, json format.
[[File:Key.png|left|frameless|30x30px]]
=== '''Key Managmeent''' ===


An example is shown below:
==== [[Node Key Management|'''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.


<pre style="white-space:pre-wrap; width:100%; border:1px solid lightgrey; background:black; color:white;">{"address":"bdcfbbd9da176e233d5a8d9a77905c2853bf10a9","crypto":{"cipher":"aes-128-ctr","ciphertext":"69ecad9449d479b7c2dc7eac19131da1af9bb64347d33e5b3bff314c7a3710f9","cipherparams":{"iv":"dd4535b11fa85e25fe0b9d4f2889aa66"},"kdf":"scrypt","kdfparams":{"dklen":32,"n":262144,"p":1,"r":8,"salt":"4be7fad8f62c395bbb7457e1e398f37a346f36df6673c377dd91d0efe201821f"},"mac":"9a7c8461b60b98d16376e665b290aecf75620d8276799fbe75045dbbf2b3bdd8"},"id":"bdcfbbd9-da17-6e23-3d5a-8d9a77905c28","version":3}</pre>
These wallets are responsible for paying the transaction fees associated with writing data on-chain for each network.


==== '''Key Password''' ====
==== '''CSA Keys''' ====
Each private key must be encrypted, and to accompish this, the Chainlink Node will require a local file (within the container) to decrypt the key.
The purpose of the CSA keys is for an unreleased feature.  No more details can be provided at this time.


<code>echo "$YOURPASSWORD" > passwordFile</code>
==== '''OCR Keys''' ====
The purpose of your OCR keys is to enable OCR communication between the nodes.


We'll need to copy both the private key file and the password file into the Chianlink Node's container.
Each Chainlink node has their own OCR keys.  Modifying these keys in any manner is not suggested.


==== '''With the key in the correct format, we will need to copy both the key and the password file into the Chainlink Node''' ====
==== '''P2P Keys''' ====
<code>docker cp /host/path/$NAME_FOR_PRIVATEKEY_FILE $CONTAINER_NAME:/$NAME_FOR_PRIVATEKEY_FILE</code>
Similar to the OCR keys, the P2P keys enable peer to peer communication among the Chainlink Nodes


<code>docker cp /host/path/$PASSWORD_FILE $CONTAINER_NAME:/$PASSWORD_FILE</code>
==== '''VRF Keys''' ====
 
The VRF Keys are specifically for the VRF functionality. No more details are available at this time.
 
Once the file is copied into the Chainlink Node's container, we will want to enter the container's bash session and authenticate with our API credentials.
 
Once done, we will want to
 
# List the contents of our working directory to make sure our private key and password files are present.
# List our keys to identify which one(s) we wish to replace.
# Delete the unwanted/unused key.
# Import the desired key.
 
==== '''List the contents of our working directory to make sure our private key and password files are present.''' ====

Assuming we want to delete the above key and replace it with a new one with the address of <code>0xDBD580eE789fF9539d6fd416d0A059C0D1cC1dbF</code>, we will need to:
