Get started with OpenRegistry Development on Linux/MacOS

Clone the repository

We recommend using the Git method to clone the repository:

git clone git@github.com:containerish/OpenRegistry.git
cd OpenRegistry

Configuration File

OpenRegistry uses the standard yaml based configuration. This configuration file is named config.yaml and can be either in the current directory or $HOME/.openregistry/config.yaml directory. Some of the features are disabled by default just to keep the on-boarding process simple.

  • Add the following contents to config.yaml file:
environment: local
debug: true
web_app_url: "http://localhost:3000"
web_app_redirect_url: "/"
web_app_error_redirect_path: "/auth/unhandled"
registry:
    dns_address: registry.local
    version: master
    fqdn: registry.local
    host: registry.local
    port: 5000
    tls:
        enabled: true
        key: .certs/openregistry.key
        cert: .certs/openregistry.cert
    services:
        - github
        - token
dfs:
    s3_any:
        access_key: <access-key>
        secret_key: <access-secret-key>
        endpoint: <s3-compatible-api-endpoint>
        bucket_name: <s3-bucket-name>
        dfs_link_resolver: <optional-dfs-link-resolver-url>
database:
    kind: postgres
    host: 0.0.0.0
    port: 5432
    username: postgres
    password: Qwerty@123
    name: open_registry

If you check the registry.tls section, you'll notice that we have enabled the TLS configuration, but we need to generate the TLS certificates before we move forward:

make certs

Database Setup

We currently use PostgreSQL, any modern version of Postgres should work fine but we recommend using the latest version.

Create Database and tables

Once you've installed PostgreSQL, login to Postgres Shell and create a database:

psql
>CREATE DATABASE open_registry;

Exit the Postgres shell.

Create the tables

We have a simple Makefile, which exposes the following commands:

  • migup - Populate all the migrations, create tables, schema changes
  • migdown - Teardown all the tables, schemas, etc
  • cleanup - Runs migdown first and then migup

Before we begin setting up tables in our database, we need to use another tool called golang-migrate. This is a database migration tool that makes database migrations dead simple. Use either of the following links to install golang-migrate:

To make sure that OpenRegistry can find all the required tables, schemas, etc, run the following command:

make migup
Output:
migrate -database 'postgres://postgres:postgres@0.0.0.0:5432/open_registry?sslmode=disable' -path db/migrations up
1/u create_users_table (9.436292ms)
2/u create_blob_table (17.848625ms)
3/u create_layer_table (24.613917ms)
4/u create_config_table (29.878583ms)
5/u create_image_manifest_table (33.47625ms)
6/u create_session_table (37.176292ms)
7/u create_verify_emails_table (40.206583ms)

Run OpenRegistry

go build
./OpenRegistry
Output:
connection to database successful
Environment: LOCAL
Service Endpoint: https://registry.local:5000
