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.

Accessing Chianlink Node CLI

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

docker exec -it $CONTAINER_NAME /bin/bash

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)

chainlink admin login

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

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.

An example is shown below

{"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}
