Packistry Deployment with Kamal

The Packistry Kamal repository provides a streamlined setup for deploying Packistry using Kamal. This guide walks you through configuring, deploying, and managing Packistry with ease.

Prerequisites​

Before getting started, make sure the following are installed, configured, and ready for use:

  • Kamal: A deployment tool that should be installed on your local machine.
  • Server Access: You must have root access to the server and an SSH key properly set up.
  • DNS Configuration: An A record must be configured for your domain, pointing to the server's IP address.
  • Container Registry Credentials: Ensure you have valid credentials for authentication with your container registry.

Setup Instructions​

1. Customize Deployment Configuration​

The deployment process is driven by the config/deploy.yml file. Modify this file to match your environment, such as server address and environment variables.

Replace all values enclosed in [] with your specific values. For example, replace [IMAGE NAME] with your actual image name, and [DOMAIN NAME] with your domain name.

service: packistry
image: [IMAGE NAME] # e.g., username/image-name

registry:
  server: ghcr.io/[IMAGE NAME]
  username: [USERNAME] # e.g., myusername
  password:
    - KAMAL_REGISTRY_PASSWORD # value is set in secrets

servers:
  - [SERVER IP] # e.g., 188.222.55.129

volumes:
  - ./data:/data

proxy:
  host: [DOMAIN NAME] # e.g., packistry.com
  ssl: true # Create an A record for the domain name pointing to your server's IP, and Kamal will obtain a free TLS certificate via Let's Encrypt.

env:
  clear:
    TRUSTED_PROXIES: * # accepts *, one or multiple IPs comma-separated.
  secret:
    - APP_KEY # value is set in secrets

builder:
  arch: arm64 # Specify your server's architecture, e.g., amd64 or arm64

2. Configure Secrets​

Copy the example secrets file and populate it with the necessary values:

cp .kamal/secrets.example .kamal/secrets

After copying, open the .kamal/secrets file and fill in the required values:

# Token for the GitHub Container Registry. Create one at https://github.com/settings/tokens/new with the "write:packages" scope.
KAMAL_REGISTRY_PASSWORD=your-registry-password
APP_KEY=your-app-key

To generate a secure APP_KEY, run:

echo "base64:$(openssl rand -base64 32)"

3. Initial Deployment Setup​

For the first deployment, Kamal will SSH into your server, install Docker, build your container image, and deploy the application.

Run the following command to begin the setup:

kamal setup

Once the setup is complete, create an admin user by accessing the shell within the container:

kamal app exec -i sh

Inside the container, run:

packistry add:user

4. Updates and Subsequent Deployments​

To deploy updates or new versions of the Packistry, follow these steps:

Update the Dockerfile: In the root of your project, modify the Dockerfile to use the latest version of the Packistry image. For example, update the version number as follows:

- FROM ghcr.io/packistry/packistry:0.7.2
+ FROM ghcr.io/packistry/packistry:0.8.0

Run the Deployment: After updating the Dockerfile, deploy the updated version by running:

kamal deploy

Kamal will pull the updated container image and deploy it to your server, ensuring that the latest version is running.

Managing Volumes​

Application data is persisted in the /root/data directory on the server. This ensures that your data remains intact between deployments and container restarts.

Additional Customization​

Feel free to adjust deployment scripts and configurations to suit your specific needs. For advanced customization options, refer to the official Kamal Documentation.
