Ansible Role: Freqtrade-Docker

Pulls and/or builds Freqtrade Docker images on Debian/Ubuntu based systems.

Information

This Ansible Role is designed to pull or build Docker images for Freqtrade - a crypto-currency algorithmic trading software developed in Python. It also allows to build a custom image based on the official Freqtrade sources, to enhance or customize it with own Python packages and/or commands.

Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. If you are new to Ansible and/or Freqtrade, it is highly recommended to get familiar with the concept of configuration management and infrastructure as code (IaaC). Please see the latest Ansible documentation for further information.

Requirements

Currently only compatible with Debian/Ubuntu based systems. Tested on Ubuntu 20.04. At the moment it is not possible to deploy it on Rasberry Pi's (armv7l) architecture!

If you want to see other OS flavors supported, you can very much submit a pull request with the desired additions.

Note that this role requires root access, so either run it in a playbook with a global become: yes, or invoke the role in your playbook like:

- hosts: tradingbots
  roles:
    - role: nightshift2k.freqtrade_docker
      become: yes

Installation

Via Github

ansible-galaxy install git+https://github.com/nightshift2k/ansible-role-freqtrade-docker.git

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

freqtrade_branch: "stable"

The branch in GitHub for the checkout of source files, and also the tag used when pulling the Docker image from registry.

docker_build_directory: "/tmp/build/docker"

Temporary directory for the Docker images. GitHub checkout will happen into subfolder, also if custom image will be build, a Dockerfile will be created there.

build_freqtrade: false

When set to true, will build the image from GitHub sources, instead of pulling it from Docker Registry.

build_freqtrade_custom: false

Will build an additional image with custom Dockerfile and Prefix (see below).

freqtrade_custom_prefix : "custom"

Needs to be defined, when build_freqtrade_custom equals true which will define the docker image name prefix (repository), so the custom image will be created as custom/freqtrade:stableon the target.

freqtrade_custom_commands:
  - "RUN pip install --upgrade pip"

Commands that will be placed into the Dockerfile, anything that is supported in Dockerfiles can be placed here as a list.

freqtrade_custom_pips:
  - finta
  - ta
  - technical

Will be placed after freqtrade_custom_commands to install custom Python packages via pip, see templates/Dockerfile.j2 inside of the role for details.
