EOSIO Node

We are going to use what's known as a SHIP node.  This node will expose the state history web socket to monitor on chain activity and it will not produce blocks.
For nodeos's documentation head over to b1's dev docs here​
If you prefer Kubernetes, checkout our dapp dsp k8s repo: https://github.com/liquidapps-io/dapp-dsp-k8s​
Minimum requirements for nodeos:
7GB of RAM - Github Link​
5GB of DISK - Github Link​
Though you will want more than this to run a testnet nodeos instance, and significantly more to handle the EOS mainnet or other mainnets.
Chain resource analysis for Mainnet/Kylin: https://docs.dfuse.io/eosio/admin-guide/system-requirements/​
This may also provide some context for resource requirements: https://github.com/EOSChronicleProject/chronicle-tutorial/blob/master/01_nodeos_server_setup.md​

Please note the following about some config.ini settings:
read-mode = head (default is: read-more = speculative and does not need to be specified in the config.ini) must not be used to prevent duplicate xwarmup actions | read more about read modes here​
if supporting the Hyperion API https://github.com/eosrio/Hyperion-History-API, must add the chain-state-history = true, note this will significantly increase storage requirements
Run
First run (from snapshot)

nodeos --disable-replay-opts --snapshot $HOME/.local/share/eosio/nodeos/data/snapshots/boot.bin --delete-all-blocks
Copied!
You will know that the node is fully synced once you see blocks being produced every half second at the head block. You can match the block number you are seeing in the nodeos logs to what bloks.io is indicating as the head block on the chain you are syncing (mainnet, Kylin etc). Once you have confirmed that it is synced press CTRL+C once, wait for the node to shutdown and proceed to the next step.
