Unpub

🧪 This is a small adaption of unpub to docker.

---

📦 About

Unpub is a self-hosted private Dart Pub server, designed for enterprise use.
It includes a simple web interface for browsing and searching package information.

---

⚠️ MongoDB Compatibility

The latest version of Unpub is v2.1.0, which was released over 2 years ago.
Using MongoDB version 4.4 in conjunction provides the most stable experience.

---

🚀 Publishing a Package

Make sure your pubspec.yaml contains the following:

name: <package_name>
description: <short description>
version: <semantic_version>
repository: <unpub_server_url>/packages/<package_name>
publish_to: <unpub_server_url>

1. Publish using Dart:

dart pub publish

---

2. Authentication issues?

If you encounter problems during publishing, set a fake auth token:

Install and use unpub_auth:

dart pub global activate unpub_auth      # install the auth tool
unpub_auth login                         # log in via provided URL
unpub_auth get | dart pub token add <unpub_server_url>
                                         # add token to pub client
dart pub publish                         # then try again

The email address used for login will be displayed on the package’s webpage under the uploader section.

---

📥 Retrieving Packages

To use a package hosted on Unpub server, add the following to your pubspec.yaml:

dependencies:
  <package_name>:
    hosted:
      name: <package_name>
      url: <unpub_server_url>
    version: <semantic_version>

---

🐳 Docker Setup

This project includes a Docker-based deployment setup.

1. Adjust Unpub settings (especially the version) in res/unpub/pubspec.yaml
2. Build the image:

   docker image build -t unpub .
   

3. Start containers:

   docker-compose up -d
   

🔧 Make sure to adjust the docker-compose.yaml file according to your needs before running the containers.

---

🎨 Customizing the Web UI

To modify the web interface (e.g. logo, colors, layout):

• Edit the files in the res/web directory
• Do this before building the Docker image, so your changes are included

---

💽 Backup & Restore Data

Packages are stored in the volume volumes/packages-data, the corresponding metadata in MongoDB (volume volumes/db-data). Make sure the volumes (see docker-compose.yaml) are not deleted.

In terms of prevent data lost, the volume volumes/packages-data has only be copied, but just copying the volume volumes/db-data is not the best choice, additionally, you have the following options:

📦 Download a Package Archive

On the Unpub web interface, you can download an archive of any package version directly under the Versions section of the package page.

---

🔄 Create a MongoDB Backup

1. Create a backup inside the container (e.g., under /data/backup)

docker exec mongo-unpub mongodump --out=/data/backup

2. Copy the backup to the host machine

docker cp mongo-unpub:/data/backup ./mongo-backup

---

♻️ Restore a MongoDB Backup

1. Copy the backup back into the container

docker cp ./mongo-backup mongo-unpub:/data/restore

2. Start the restore process

docker exec mongo-unpub mongorestore /data/restore

🔁 Optional: Drop existing data before restoring:

docker exec mongo-unpub mongorestore --drop /data/restore

---

🗄️ Using the Provided Backup Service

A dedicated backup service is included to simplify data preservation. It performs a full backup by copying all unpub packages and dumping the MongoDB database in one step.

To run the backup, use the following command:

docker-compose run --rm backup

The resulting archive file will be saved in the volumes/backups directory.

---

🌐 Access

Once deployed, you can access the web interface via the unpub server address:

scheme://<unpub-server>/

Depending on the settings in docker-compose.yaml the uri can differ. Without reverse proxy and other settings the server can be reached under the adress:

http://localhost:8080
