Dockyard is an container registry with volume management function for Docker, rkt or other container engines. Its features include:
- Image storage and meta discovery for popular container runtime such as docker and rkt.
- Image distribution by P2P protocol.
- Public and private repositories for users and organizations.
- Built-in object storage engine and drivers.
- Built-in object storage service.
- Built-in container volume management for runtime with distributed file system.
- Convert image object to distributed file-system for container mount and start directly.
- Container image encryption and verification.
The architecture of Dockyard illustrated as below:
Please refer to design for more information.
Confused by docker registry v1 and v2? Helpless to face different container images(e.g. Docker or rkt)? Too lazy to deal with container image storage problems? Do not worry, Dockyard is coming for you. Please have a cup of tea and wait for this whole thing to blow over.
With dockyard you can manage your container images as freely as you can, you need not to concern with different container engines, and you will not be locked in by docker hub. Just throw these tricky work to Dockyard and focus on your main business.
Please watch this space for updates on the progress. Dockyard project is under heavy development and is ready for simple use.
- Docker registry V1
- Docker registry V2
- Object storage backend and drivers
- REST API interface
- Rkt Meta Discovery
- P2P modules
- Object storage service
Work in the future illustrated as below:
- Volume management with distributed file-system.
- Convert between object storage and distributed file-system.
- Web interface and CLI interface.
- Container image encryption and verification.
Please refer to roadmap for more information.
Although dockyard is still in development, we encourage you to try out the tool and give feedback.
Installation is as simple as:
# create a 'github.com/containerops' directory in your GOPATH/src
cd github.com/containerops
git clone https://github.com/containerops/dockyard
cd dockyard
make
sudo make install
or as involved as:
go get github.com/containerops/dockyard
cd $GOPATH/src/github.com/containerops/dockyard
go build
You can build Dockyard via make
that depends on Godeps or go build
that depends on your local package.There may be some problems occured when executing go get
in chinese network,you'd better use make
to build it.
It is quite easy to use Dockyard, only a little work should be done before starting dockyard service. Take it easy, just follow the instructions as below.
Please add a runtime config file named runtime.conf
under dockyard/conf
before starting dockyard
service. Below is a runtime.conf
example:
runmode = dev
listenmode = https
httpscertfile = cert/containerops/containerops.crt
httpskeyfile = cert/containerops/containerops.key
[log]
filepath = log/containerops-log
[db]
driver = mysql
uri = localhost:3306
user = root
passwd = 123456
name = dockyard
[dockyard]
path = data
domains = containerops.me
registry = 0.9
distribution = registry/2.0
standalone = true
driver = qiniu
[qiniu]
endpoint = sample.com
bucket = dockyard
accessKeyID = userid
accessKeysecret = userkey
- runmode: application run mode must be
dev
orprod
. - listenmode: support
http
andhttps
protocol. - httpscertfile: specify user own https certificate file by this parameter.
- httpskeyfile: specify user own https key file by this parameter.
- [log] filepath: specify where Dockyard logs are stored.
- [db] driver: specify
mysql
orredis
to store image context. - [db] uri: Dockyard database provider is
mysql
orredis
,IP
andPort
would be specified before database boots. - [db] user: optionally,specify the user to login and access when
mysql
is used. - [db] passwd: specify the password to login and access db.
- [db] name: optionally,specify db name when
mysql
is used. - [db] db: optionally,specify db partition number when
redis
is used. - [dockyard] path: specify where
Docker
andRocket
image files are stored. - [dockyard] domains: registry server name or IP.
- [dockyard] registry: specify the version of Docker V1 protocol.
- [dockyard] distribution: specify the version of Docker V2 protocol.
- [dockyard] standalone: must be
true
orfalse
,specify run mode whether do authorization checks or not.
Specify parameters to enable Dockyard notification function. Below is an example of config.json
:
{
"notifications":{
"name":"notifications",
"endpoints":[
{
"name":"notifyProxy",
"url":"http://notifyproxy:8088/events",
"headers":{"Authorization":["Bearer","token"]},
"timeout":5000,
"threshold":5,
"backoff":5000,
"eventdb":"/tmp",
"disabled":false
}
]
}
}
It's a Nginx config example. You can change client_max_body_size what limited upload file size. You should copy containerops.me
keys from cert/containerops.me
to /etc/nginx
, then run Dockyard with http
mode and listen on 127.0.0.1:9911
.
upstream dockyard_upstream {
server 127.0.0.1:9911;
}
server {
listen 80;
server_name containerops.me;
rewrite ^/(.*)$ https://containerops.me/$1 permanent;
}
server {
listen 443;
server_name containerops.me;
access_log /var/log/nginx/containerops-me.log;
error_log /var/log/nginx/containerops-me-errror.log;
ssl on;
ssl_certificate /etc/nginx/containerops.me.crt;
ssl_certificate_key /etc/nginx/containerops.me.key;
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;
}
}
- Run directly:
./dockyard web --address 0.0.0.0 --port 80
- Run with Nginx:
./dockyard web --address 127.0.0.1 --port 9911
Congratulations! Dockyard is ready for you, just enjoy it:-)
- Add containerops.me in your
hosts
file like192.168.1.66 containerops.me
with IP which rundockyard
. - Then
push
withdocker push containerops.me/somebody/ubuntu
. - You could
pull
withdocker pull -a containerops.me/somebody/ubuntu
. - Work for fun!
