Running a V1 Node
We support running a full node on Ubuntu 22.04 LTS.
Minimum hardware requirements
- 8 cores of CPU and 16 gigabytes of memory (RAM).
- fixed size hard disk, 2TB or elastic volumes, 2TB.
- install docker
- install docker compose-plugin
Storing the node data in a different directory (optional)
The default node data directory(./node-data) is in the same directory as the docker-compose.yml file. Mount a new host folder, replace the path ./node-data in docker-compose.yml with the new directory.
Running a full node
- Build docker image locally(optional)
- Run node(If the docker image does not exist, pull the image from Docker Hub automaticlly.)
- Stop the full node
- Download the node data archive file(recommend).
- Note that this process may take several hours due to the size of the blockchain.
Checking the last synced block
If you change the default data directory for node, replace the path "./node-data" with your new directory. or run the command in the same directory as the docker-compose.yml file. You maybe need to wait about serval minutes, and then the node will sync blocks and generate committed logs.
Restarting a node
Sometimes a node can get stuck. You can restart the node by finding the docker container name by doing
And then copying the name (in our case the name was cmp_mainnet_node and doing:
