Node update

Before the update

  1. Check out the Power Telegram chat, the Power news, or information about the problems with the node in Zabbix. There you will find information about the necessity of update.

  2. Back up your node.config and genesis.txt.

  3. Check your node version by running the following command:

    curl -s http://{your_node_hostname}:1080/api/node/status | jq .status.ver
    note

    Your node may have automatic updates configured previously. In this case, you don't need to update your node manually (only for nodes started from the Docker image).

    Read this manual to learn how to configure automatic node updates using Watchtower (only for nodes started from the Docker image).

Updating your node built from Docker image

Check your node version by running the following command:

curl -s http://{your_node_hostname}:1080/api/node/status | jq .status.ver

    docker stop tpnode
  2. Delete the container:

    docker rm tpnode
  3. Update the Docker image:

  4. Restart your node by running the starting command:

     docker run -d \
    --name tpnode \
    --restart unless-stopped \
    --mount type=bind,source=/opt/thepower/db,target=/opt/thepower/db \
    --mount type=bind,source=/opt/thepower/log,target=/opt/thepower/log \
    --mount type=bind,source=/opt/thepower/node.config,target=/opt/thepower/node.config \
    --mount type=bind,source=/opt/thepower/genesis.txt,target=/opt/thepower/genesis.txt \

To update your node:

  1. Go to your source code directory:

    git pull 
  3. Build your node according to this guide.

  4. Stop your node after it is built:

    systemctl stop tpnode.service
  5. Replace your node code by rewriting the versions of directories:
