How to start a TP-Node from a Docker image?

You can start a TP-Node using the Docker image.

Setting up the environment

Before you start a TP-Node using the Docker image:

  1. Ensure you have Docker installed on your machine.

  2. If not, refer to Docker Installation Guide.

  3. Check user groups you belong to by running the following command:

    $ groups

  4. If you don't belong to the user group docker, you will not be able to start Docker. To resolve this problem, run:

    # usermod -a docker

  5. Ensure you have the actual genesis.txt and node.config files.

  6. Create db and log directories in your working directory (/opt, for instance).

    Hint

    You can create an additional directory named thepower, for example, and place db and log as subdirectories there.

  7. Place the files genesis.txt and node.config near db and log directories.

Starting the node

To start the TP-Node run the following command:

docker run -d \
--name tpnode \
--mount type=bind,source="$(pwd)"/db,target=/opt/thepower/db \
--mount type=bind,source="$(pwd)"/log,target=/opt/thepower/log \
--mount type=bind,source="$(pwd)"/node.config,target=/opt/thepower/node.config \
--mount type=bind,source="$(pwd)"/genesis.txt,target=/opt/thepower/genesis.txt \
-p 43292:43292 \
-p 43392:43392 \
-p 43219:43219 \
thepowerio/tpnode

where:

Command Description
docker run -d This command starts Docker in the background
--name tpnode This command specifies the name (optional)
--mount type=bind,source="$(pwd)"/db,target=/opt/thepower/db Path to the database. Bound to Docker. /opt here is mandatory, because it is the path inside the container.
--mount type=bind,source="$(pwd)"/log,target=/opt/thepower/log Path to log files. Bound to Docker. /opt here is mandatory, because it is the path inside the container.
--mount type=bind,source="$(pwd)"/node.config,target=/opt/thepower/node.config Path to your node.config file. Bound to Docker. /opt here is mandatory, because it is the path inside the container.
--mount type=bind,source="$(pwd)"/genesis.txt,target=/opt/thepower/genesis.txt Path to your genesis.txt. Bound to Docker. /opt here is mandatory, because it is the path inside the container.
-p 43292:43292
-p 43392:43392
-p 43219:43219		 These commands specify all necessary local ports. In this examples ports api, apis, and tpic are used. You can specify any port in node.config file
thepowerio/tpnode Path to Docker image.
