Dockyard – Container And Artifact Repository


What is Dockyard ?

Dockyard is a container and artifact repository storing and distributing container image, software artifact and virtual images of KVM or XEN. It’s key features and goals include:

  • Multi supported distribute protocols include Docker Registry V1 & V2 and App Container Image Discovery.
  • Multi supported software artifact format include jar, war, tar and so on.
  • Multi supported virtual images of KVM, XEN, VirtualBox and so on.
  • Container image, software artifact and virtual images encryption, verification and vulnerability analysis.
  • Custome distribute protocol by framework base HTTPS and peer to peer.
  • Authentication in distributing process and authorization for public and private repository.
  • Supporting mainstream object storage service like Amazon S3, Google Cloud Storage.
  • Built-in object storage service for deployment convenience.
  • Web UI portal for all functions above.

Why it matters ?

The Dockyard’s Story 🙂

Runtime configuration

runmode = "dev"

listenmode = "https"
httpscertfile = "cert/containerops/containerops.crt"
httpskeyfile = "cert/containerops/containerops.key"

domain = ""

filepath = "log/backend.log"
level = "info"

driver = "mysql"
uri = "containerops:[email protected]/containerops?charset=utf8&parseTime=True&loc=Asia%2FShanghai"

domains = ""

standalone = "true"
version = "0.9"
storage = "/tmp/data/dockerv1"

distribution = "registry/2.0"
storage = "/tmp/data/dockerv2"

storage = "/tmp/data/appc"

keymanager = "/tmp/containerops_keymanager_cache"
storage = "/tmp/containerops_storage_cache"

Nginx configuration

It’s a Nginx config example. You can change client_max_body_size what limited upload file size. You should copy keys from cert/ to /etc/nginx, then run Dockyard with http mode and listen on

upstream dockyard_upstream {

server {
  listen 80;
  rewrite  ^/(.*)$$1  permanent;

server {
  listen 443;


  access_log /var/log/nginx/containerops-me.log;
  error_log /var/log/nginx/containerops-me-errror.log;

  ssl on;
  ssl_certificate /etc/nginx/;
  ssl_certificate_key /etc/nginx/;

  client_max_body_size 1024m;
  chunked_transfer_encoding on;

  proxy_redirect     off;
  proxy_set_header   X-Real-IP $remote_addr;
  proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header   X-Forwarded-Proto $scheme;
  proxy_set_header   Host $http_host;
  proxy_set_header   X-NginX-Proxy true;
  proxy_set_header   Connection "";
  proxy_http_version 1.1;

  location / {
    proxy_pass         http://dockyard_upstream;

Database Configuration

Database SQL

INSERT INTO mysql.user(Host,User,Password) VALUES ('localhost', 'containerops', password('containerops'));
CREATE DATABASE `containerops` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON containerops.* TO [email protected] IDENTIFIED BY 'containerops';

Initlization Tables

./dockyard database migrate

Start dockyard service

  • Run directly:
./dockyard daemon run --address --port 443
  • Run with Nginx:
./dockyard daemon run --address --port 9911 &

How to build

We are using glide as package manager/

  • retrieve dependencies
glide install
  • build (with go 1.6+)
go build

Pull Requests

If you want to contribute to the template, you can create pull requests. All pull requests must be done to the develop branch. We are working on build an automated tests with ourself means containerops, now we just add Travis CI instead.

Who should join

  • Ones who want to choose a container image hub instead of docker hub.
  • Ones who want to ease the burden of container image management.
