# Full node with Docker This guide will explain how to install the `fxcored mainnet` or `fxcored testnet` command line interface (CLI) on your system with `Docker` option. With these installed on a server, you can participate on the mainnet or testnet as a [Validator](/pundi/pundi-aifx/validators.md). ## Install Pundi AIFX > **You need to** [**install Pundi AIFX**](/pundi/pundi-aifx/installation.md) **before you go further** ### Use Docker * Pull docker images > if you do not already have docker installed, there will be a prompt for you to install it.

This may take a few hours and your node has to be fully synced up before proceeding to the next step. You may cross reference the latest block you are synced to "sync\_info": "latest\_block\_height" and the latest block height of our Testnet blockchain on our [Testnet blockchain explorer](https://testnet.pundiscan.io/fxcore/blocks) or our [Mainnet](https://pundiscan.io/fxcore/proposals). > Make sure that every node has a unique `priv_validator.json`. Do not copy the `priv_validator.json` from an old node to multiple new nodes. Running two nodes with the same `priv_validator.json` will cause you to double sign. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://pundi.gitbook.io/pundi/pundi-aifx/setup-node/full-node-with-docker.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
