Docker Compose

Warning

We currently do not support Docker environments in productive use. We recommend using it for use in a test phase!

Note

You need at least 4 GB of RAM to run the containers. We recommend 8GB for a better performance.

Docker is a container-based software framework for automating deployment of applications. Compose is a tool for defining and running multi-container Docker applications.

This repo is meant to be the starting point for somebody who likes to use dockerized multi-container OpenCelium in production. The OpenCelium Docker image uses the stable branch of OpenCelium’s Git repo.

The Docker images are hosted on Dockerhub.

Install Docker Environment:

  1. Install Docker:

Use default Docker installation guide.

  1. Getting started with opencelium-docker-compose:

1git clone https://github.com/opencelium/opencelium-docker.git
2cd opencelium-docker

Note

We recommend to use always the latest tag version.

  1. Start OpenCelium using DockerHub images

1docker-compose up -d

DEB package for Ubuntu 22.04 LTS

Prepare environment:

  1. Update Ubuntu system:

3apt update
4apt install neo4j=1:5.7.0
5/usr/bin/neo4j-admin dbms set-initial-password secret1234

Note

Change password (secret1234) if you want.

Install Application:

  1. Install deb package for OpenCelium:

1curl -s https://packagecloud.io/install/repositories/becon/opencelium/script.deb.sh | sudo bash

3apt update
4apt install opencelium

Configure environment:

  1. Secure MySql and set root password (required for new MySql installations):

If this works (without your password), please set your password again with this command:

1mysql -u root -e "ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';"

Change password (root) if you want.
