Install Resoto with Docker

Docker provides the ability to run an application in a loosely isolated environment called a container. For more information on Docker, please see the official Docker documentation.

Resoto consists of multiple components published as individual Docker images:

• somecr.io/someengineering/resotocore maintains the infrastructure graph.
• somecr.io/someengineering/resotoworker collects infrastructure data from the cloud provider APIs.
• somecr.io/someengineering/resotometrics exports metrics in Prometheus format.
• somecr.io/someengineering/resotoshell provides the command-line interface used to interact with Resoto.

Prerequisites

• Docker
• Docker Compose
• At least 2 CPU cores and 8 GB of RAM

note

Resoto performs CPU-intensive graph operations. In a production setup, we recommend at least four cores and 16 gigabytes of RAM. See Configuring Resoto Worker for more information.

Installing Resoto

1. Fetch the required files from the someengineering/resoto GitHub repository:

   $ mkdir -p resoto/dockerV2
   $ cd resoto
   $ curl -Lo docker-compose.yaml https://github.com/someengineering/resoto/releases/download/2.4.7/docker-compose.yaml
   $ curl -Lo dockerV2/prometheus.yml https://raw.githubusercontent.com/someengineering/resoto/2.4.7/dockerV2/prometheus.yml

2. Start the services defined in the docker-compose.yaml file:

   $ docker-compose up -d

   Upon execution of docker-compose up -d, Docker Compose will start all components and set up the system. This process takes approximately 1-3 minutes, depending on your machine and internet connection.

   note

   Docker Compose V2 integrated compose functions in to the Docker platform.

   In Docker Compose V2, the command is docker compose (no hyphen) instead of docker-compose.

Launching the Command-Line Interface

The resh command is used to interact with resotocore.

Simply execute the following to access the Resoto Shell interface:

$ docker exec -it resotoshell resh
