Quilibrium Docker Instructions

Install Docker on a Server

Important

You have to install Docker Engine on your server, you don't want to install Docker Desktop.

The official Linux installation instructions start here:
https://docs.docker.com/engine/install/

For Ubuntu you can start here:
https://docs.docker.com/engine/install/ubuntu/

While there are several installation methods, you really want to use the apt repository, this way you get automatic updates.

Make sure you also follow the Linux post-installation steps:
https://docs.docker.com/engine/install/linux-postinstall/

Install Docker on a Desktop

For a Linux desktop follow the server installation steps above, do not install Docker Desktop for Linux unless you know what you are doing.

For Mac and Windows follow the corresponding Docker Desktop installation links from the top of:
https://docs.docker.com/engine/install/

Running a Node

Copy docker-compose.yml to a new folder on a server. The official Docker image provided by Quilibrium Network will be pulled.

A .config/ subfolder will be created in this folder, this will hold both configuration and the node storage.

Optionally you can also copy Taskfile.yaml and .env.example to the server, if you are planning to use them. See below.

New Instance

If you are starting a brand new node then simply run Quilibrium in a container with:

docker compose up -d

A .config/ subfolder will be created under the current folder, this is mapped inside the container.

Important

Once the node is running (the -node-info command shows a balance) make sure you backup config.yml and keys.yml.

Restore Previous Instance

If you have both config.yml and keys.yml backed up from a previous instance then follow these steps to restore them:

  1. Create an empty .config/ subfolder.
  2. Copy config.yml and keys.yml to .config/.
  3. Start the node with:
    docker compose up -d
    

Task

You can also use the Task tool, it is a simple build tool that takes care of running complex commands and intereacting with the container. The tasks are all defined in Taskfile.yaml.

You can optionally create an .env file, in the same folder to override specific parameters. Right now only one optional env var is supported with Task and that is QUILIBRIUM_IMAGE_NAME, if you want to change the default image name from quilibrium to something else. If you are pushing your images to GitHub, for example, then you have to follow the GitHub naming convention and use a name like ghcr.io/mscurtescu/ceremonyclient. See the .env.example sample file, and keep in mind that .env is shared with docker-compose.yml.

Bellow there are example interactions with Task.

Start the container through docker compose:

task up

Show the logs through docker compose:

task logs

Drop into a shell inside the running container:

task shell

Stop the running container(s):

task down

Backup the critical configuration:

task backup

The above command will create a backup.tar.gz archive in the current folder, you still have to copy this file from the server into a safe location. The command adds the config.yml and keys.yml files from the .config/ subfolder to the archive, with the ownership of the current user.

Customizing docker-compose.yml

If you want to change certain parameters in docker-compose.yml it is better not to edit the file directly as new versions pushed through git would overwrite your changes. A more flexible solution is to create another file called docker-compose.override.yml right next to it and specifying the necessary overriding changes there.

For example:

services:
  node:
    image: ghcr.io/mscurtescu/ceremonyclient
    restart: on-failure:7

The above will override the image name and also the restart policy.

You can optionally create an .env file, in the same folder to override specific parameters. See the .env.example sample file, and keep in mind that .env is shared with Taskfile.yaml. You can customize the image name and port mappings.

To check if your overrides are being picked up run the following command:

docker compose config

This will output the merged and canonical compose file that will be used to run the container(s).

Interact with a running container

Drop into a shell inside a running container:

docker compose exec -it node sh

Watch the logs:

docker compose logs -f

Get the node related info (peer id, version, max frame and balance):

docker compose exec node node -node-info

Run the DB console:

docker compose exec node node -db-console

Run the Quilibrium client:

docker compose exec node qclient help
docker compose exec node qclient token help
docker compose exec node qclient token balance
