Ollama User Guide

Introduction to Ollama

Ollama is a command-line tool designed to simplify the management of Docker images and containers. It allows users to efficiently copy, push, and pull Docker images between different environments, such as local development machines, private registries, or public cloud platforms. Ollama is especially useful for developers and system administrators looking to streamline their Docker workflows.

Prerequisites

Before you begin using Ollama, ensure that you have Docker installed on your system. Docker provides the underlying technology that Ollama manipulates. You can download Docker from the official Docker website.

Installing Ollama

Currently, Ollama does not have a standalone installation package. Typically, it would be installed via a package manager or directly from its source repository. This guide will assume you have direct access to the Ollama executable.

Setting Up a Docker Private Registry

To test Ollama’s functionality, you can set up a local Docker registry:

1. Start the Docker Registry Container:

   <syntaxhighlight lang="bash">docker run -d -p 5001:5000 --name registry registry:2</syntaxhighlight>

   This command runs a Docker registry as a container, accessible on port 5001 of your localhost.

Using Ollama

Basic Commands

1. Copying an Image to a Local Registry:

   <syntaxhighlight lang="bash">ollama cp llama2:latest localhost:5001/ryan/llama2:latest</syntaxhighlight>

   This command copies an image named llama2:latest to your local registry under the namespace ryan.

2. Pushing an Image:

   <syntaxhighlight lang="bash">ollama push localhost:5001/ryan/llama2:latest --insecure</syntaxhighlight>

   This pushes the image to the local registry. The --insecure flag is used because local registries typically do not have HTTPS configured.

3. Pulling an Image Back to Ollama:

   <syntaxhighlight lang="bash">ollama pull localhost:5001/ryan/llama2:latest --insecure</syntaxhighlight>

   This pulls the image from the local registry back to your local machine. ### Executing Commands

To prompt Ollama, open your command line or terminal:

Navigate to the directory where Ollama is installed if it’s not added to your PATH. Type the ollama command followed by the specific action you want to perform (e.g., cp, push, pull). Include the necessary parameters and flags as shown in the examples above.

Advanced Usage

Managing Multiple Registries: Ollama can handle multiple Docker registries. You can configure Ollama to interact with several registries by specifying different endpoints in the commands. Automating Workflows: Ollama can be integrated into scripts or CI/CD pipelines to automate the pushing and pulling of Docker images as part of a build process or deployment strategy.
