# Docker Compose V1 + V2 registry
This compose configuration will setup a v1 and v2 registry behind an nginx
proxy. By default the combined registry may be accessed at localhost:5000.
This registry does not support pushing images to v2 and pull from v1. Clients
from before 1.6 will be configured to use the v1 registry, and newer clients
will use the v2 registry.
This compose configuration configures a `v1` and `v2` registry behind an `nginx`
proxy. By default, you can access the combined registry at `localhost:5000`.
## Prerequisites
Install [docker-compose](https://github.com/docker/compose)
The configuration does not support pushing images to `v2` and pulling from `v1`.
If a `docker` client has a version less than 1.6, Nginx will route its requests
to the 1.0 registry. Requests from newer clients will route to the 2.0 registry.
## How to run
```
$ docker-compose up
```
### Install Docker Compose
1. Open a new terminal on the host with your `distribution` source.
2. Get the `docker-compose` binary.
$ sudo wget https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` -O /usr/local/bin/docker-compose
This command installs the binary in the `/usr/local/bin` directory.
3. Add executable permissions to the binary.
$ sudo chmod +x /usr/local/bin/docker-compose
## Build and run with Compose
1. In your terminal, navigate to the `distribution/contrib/compose` directory
This directory includes a single `docker-compose.yml` configuration.
nginx:
build: "nginx"
ports:
- "5000:5000"
links:
- registryv1:registryv1
- registryv2:registryv2
registryv1:
image: registry
ports:
- "5000"
registryv2:
build: "../../"
ports:
- "5000"
This configuration builds a new `nginx` image as specified by the
`nginx/Dockerfile` file. The 1.0 registry comes from Docker's official
public image. Finally, the registry 2.0 image is built from the
`distribution/Dockerfile` you've used previously.
2. Get a registry 1.0 image.
$ docker pull registry:0.9.1
The Compose configuration looks for this image locally. If you don't do this
step, later steps can fail.
3. Build `nginx`, the registry 2.0 image, and
$ docker-compose build
registryv1 uses an image, skipping

### Explore a bit
1. Check for TLS on your `nginx` server.

* SSL certificate problem: self signed certificate
* Closing connection 0
curl: (60) SSL certificate problem: self signed certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
2. Tag the `v1` registry image.
$ docker tag registry:latest localhost:5000/registry_one:latest
2. Push it to the localhost.
$ docker push localhost:5000/registry_one:latest
If you are using the 1.6 Docker client, this pushes the image the `v2 `registry.
4. Use `curl` to list the image in the registry.
$ curl -v -X GET http://localhost:32777/v2/registry1/tags/list
* Hostname was NOT found in DNS cache
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 32777 (#0)

This example refers to the specific port assigned to the 2.0 registry. You saw
this port earlier, when you used `docker ps` to show your running containers.

### Add the certificates to the image
6. List the contents of the `certs` directory.
In this section, you copy the certifications from your `certs` directory into
your base image.
1. Edit the `Dockerfile` and add a `CERTS_PATH` environment variable.
ENV CERTS_PATH /etc/docker/registry/certs
$ ls certs
domain.crt domain.key
2. Add a line to make the `CERTS_PATH` in the filesystem.
RUN mkdir -v $CERTS_PATH
3. Add `RUN` instructions to hard link your new certifications into this path:
RUN cp -lv ./certs/domain.crt $CERTS_PATH
RUN cp -lv ./certs/domain.key $CERTS_PATH
This copies your certifications into your container.
4. Save your work.
At this point your Dockerfile should look like the following:
FROM golang:1.4
ENV CONFIG_PATH /etc/docker/registry/config.yml
ENV CERTS_PATH /etc/docker/registry/certs
ENV DISTRIBUTION_DIR /go/src/github.com/docker/distribution

RUN cp -lv ./certs/domain.crt $CERTS_PATH
RUN cp -lv ./certs/domain.key $CERTS_PATH
RUN cp -lv ./cmd/registry/config.yml $CONFIG_PATH
5. Before you close the Dockerfile look for an instruction to copy the `config.yml` file.
When you build this container, the `certs` directory and its contents
automatically get copied also.

## Configure Nginx with a v1 and v2 registry
This sections describes how to user `docker-compose` to run a combined version
1 and version 2.0 registry behind an `nginx` proxy. The combined registry is
accessed at `localhost:5000`. If a `docker` client has a version less than 1.6,
Nginx will route its requests to the 1.0 registry. Requests from newer clients
will route to the 2.0 registry.
This procedure uses the same `distribution` directory you created in the last
procedure. The directory includes an example `compose` configuration.
### Install Docker Compose
1. Open a new terminal on the host with your `distribution` directory.
2. Get the `docker-compose` binary.
$ sudo wget https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` -O /usr/local/bin/docker-compose
This command installs the binary in the `/usr/local/bin` directory.
3. Add executable permissions to the binary.
$ sudo chmod +x /usr/local/bin/docker-compose
## Adding a middleware configuration
This section describes how to configure storage middleware in a registry.
Middleware allows the registry to server layers via a content delivery network
(CDN). This is useful for reducing requests to the storage layer.
### Do some housekeeping
Currently, the registry supports [Amazon
Cloudfront](http://aws.amazon.com/cloudfront/). You can only use Cloudfront in
conjunction with the S3 storage driver.
1. Remove any previous images.
<table>
<tr>
<th>Parameter</th>
<th>Description</th>
</tr>
<tr>
<td><code>name</code></td>
<td>The storage middleware name. Currently <code>cloudfront</code> is an accepted value.</td>
</tr>
<tr>
<td><code>disabled<code></td>
<td>Set to <code>false</code> to easily disable the middleware.</td>
</tr>
<tr>
<td><code>options:</code></td>
<td>
A set of key/value options to configure the middleware.
<ul>
<li><code>baseurl:</code> The Cloudfront base URL.</li>
<li><code>privatekey:</code> The location of your AWS private key on the filesystem. </li>
<li><code>keypairid:</code> The ID of your Cloudfront keypair. </li>
<li><code>duration:</code> The duration in minutes for which the URL is valid. Default is 20. </li>
</ul>
</td>
</tr>
</table>
$ docker rmi -f $(docker images -q -a )
This step is a house keeping step. It prevents you from mistakenly picking up
an old image as you work through this example.
2. Edit the `distribution/cmd/registry/config.yml` file and remove the `tls` block.
The following example illustrates these values:
If you worked through the previous example, you'll have a `tls` block.
```
middleware:
storage:
- name: cloudfront
disabled: false
options:
baseurl: http://d111111abcdef8.cloudfront.net
privatekey: /path/to/asecret.pem
keypairid: asecret
duration: 60
```
4. Save any changes and close the file.
### Configure SSL
>**Note**: Cloudfront keys exist separately to other AWS keys. See
>[the documentation on AWS credentials](http://docs.aws.amazon.com/AWSSecurityCredentials/1.0/
>AboutAWSCredentials.html#KeyPairs) for more information.
1. Change to the `distribution/contrib/compose/nginx` directory.
This directory contains configuration files for Nginx and both registries.
2. Use SSL to generate some self-signed certificates.
$ openssl req \
-newkey rsa:2048 -nodes -keyout domain.key \
-x509 -days 365 -out domain.crt
This command prompts you for basic information it needs to create certificates.
3. Edit the `Dockerfile`and add the following lines.
**TODO(stevvooe): Need a "best practice" configuration overview. Perhaps, we can point to a documentation section.
COPY domain.crt /etc/nginx/domain.crt
COPY domain.key /etc/nginx/domain.key
When you are done, the file looks like the following.
FROM nginx:1.7
COPY nginx.conf /etc/nginx/nginx.conf
COPY registry.conf /etc/nginx/conf.d/registry.conf
COPY docker-registry.conf /etc/nginx/docker-registry.conf
COPY docker-registry-v2.conf /etc/nginx/docker-registry-v2.conf
COPY domain.crt /etc/nginx/domain.crt
COPY domain.key /etc/nginx/domain.key
# Configure nginx to deploy alongside v1 registry
4. Save and close the `Dockerfile` file.
5. Edit the `registry.conf` file and add the following configuration.
This sections describes how to configure nginx to proxy to both a v1 and v2
registry. Nginx will handle routing of to the correct registry based on the
URL and Docker client version.
ssl on;
ssl_certificate /etc/nginx/domain.crt;
ssl_certificate_key /etc/nginx/domain.key;
This is an `nginx` configuration file.
## Example configuration
With v1 registry running at `localhost:5001` and v2 registry running at
`localhost:5002`. Add this to `/etc/nginx/conf.d/registry.conf`.
```

}
}
```
$ docker pull registry:0.9.1
## Running nginx without a v1 registry
When running a v2 registry behind nginx without a v1 registry, the `/v1/` endpoint should
be explicitly configured to return a 404 if only the `/v2/` route is proxied. This
is needed due to the v1 registry fallback logic within Docker 1.5 and 1.6 which will attempt
to retrieve content from the v1 endpoint if no content was retrieved from v2.
The Compose configuration looks for this image locally. If you don't do this
step, later steps can fail.
3. Build `nginx`, the registry 2.0 image, and
$ docker-compose build

### Explore a bit
1. Check for TLS on your `nginx` server.
$ curl -v https://localhost:5000
* Rebuilt URL to: https://localhost:5000/
* Hostname was NOT found in DNS cache
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 5000 (#0)
* successfully set certificate verify locations:
* CAfile: none
CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* SSLv3, TLS handshake, Server hello (2):
* SSLv3, TLS handshake, CERT (11):
* SSLv3, TLS alert, Server hello (2):
* SSL certificate problem: self signed certificate
* Closing connection 0
curl: (60) SSL certificate problem: self signed certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
2. Tag the `v1` registry image.
$ docker tag registry:latest localhost:5000/registry_one:latest
2. Push it to the localhost.
$ docker push localhost:5000/registry_one:latest
If you are using the 1.6 Docker client, this pushes the image the `v2 `registry.
4. Use `curl` to list the image in the registry.
$ curl -v -X GET http://localhost:32777/v2/registry1/tags/list
* Hostname was NOT found in DNS cache
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 32777 (#0)
> GET /v2/registry1/tags/list HTTP/1.1
> User-Agent: curl/7.36.0
> Host: localhost:32777
> Accept: */*

This example refers to the specific port assigned to the 2.0 registry. You saw
this port earlier, when you used `docker ps` to show your running containers.
Add this location block to explicitly block v1 requests.
```
localhost /v1/ {
return 404;
}
```
