Deploying Docker to Amazon using Tutum explained how to deploy a Docker image to Docker Tutum. Tutum is now Docker Cloud.
Ler Announcing Docker Cloud para mais detalhes.
The key features of Docker Cloud are:
- Authentication using Docker ID
- Integration with Docker Hub
- Support for Docker official repositories
- Commercially supported Docker Engine
- Ability to deploy and scale your applications using GUI, API and CLI
This blog will show:
- Key concepts of Docker Cloud
- How to create a new Docker Cloud Node
- How to install Docker Cloud CLI
- How to create a new Docker Cloud Service
- Access Couchbase Server in Docker Cloud
- How to terminate the Docker Cloud Service and Node
And finally it’ll leave with some references for Docker Cloud docs.
The blog will use Couchbase Server – an open source, highly scalable, JSON document database for the Docker image.
Docker Cloud TL;DR
Here are the quick commands to run a Docker image using Docker Cloud in Amazon:
|
1 2 3 4 5 |
brew instalar docker–nuvem docker–nuvem nodecluster criar –t 1 —tag Couchbase Couchbase–nó aws us–west–1 m3.large docker–nuvem service criar —tag Couchbase –p 8091:8091 –p 8092:8092 –p 8093:8093 –p 11210:11210 arungupta/Couchbase docker–nuvem service start {SERVICE_ID} docker–nuvem service inspect {SERVICE_ID} | jq “.container_ports[0].endpoint_uri” | sed ‘s/tcp/http/g’ |
More details below.
Key Concepts of Docker Cloud
Let’s understand the core concepts of Docker Cloud:
- Nodes are individual Linux hosts/VMs used to deploy and run your applications. New nodes can be provisioned to increase the capacity. Docker Cloud does not provide hosting services. Nodes are provisioned using physical servers, virtual machine or cloud providers.
- Node Clusters are logical groups of nodes of the same type. Node Clusters allow to scale the infrastructure easily by provisioning more nodes.
- Services are logical groups of containers from the same image. Services make it simple to scale your application across different nodes.
Docker Cloud can be managed with Web, CLI ou API REST. This blog will use the Docker Cloud CLI to perform all the commands.
Install Docker Cloud CLI
Install Docker Cloud CLI:
|
1 2 3 4 5 |
brew instalar docker–nuvem ==> Downloading https://homebrew.bintray.com/bottles/docker-cloud-1.0.2.yosemite.bottle.tar.gz Already downloaded: /Library/Caches/Homebrew/docker–nuvem–1.0.2.yosemite.bottle.tar.gz ==> Pouring docker–nuvem–1.0.2.yosemite.bottle.tar.gz ? /usr/local/Cellar/docker–nuvem/1.0.2: 482 files, 4.1M |

Create new Docker Cloud Node
Register your cloud provider credentials with Docker Cloud Web UI as explained in Link to a Cloud Service Provider. Amazon, Digital Ocean, Azure, and other cloud providers are supported.
Create a new node cluster with a single node:
|
1 2 |
docker–nuvem nodecluster criar –t 1 —tag Couchbase Couchbase–nó aws us–west–1 m3.large 42a34e04–02e1–47be–bf87–ec06e0e0b604 |
This node cluster has a single node (-t 1) and uses the tag “couchbase” (--tag couchbase). Last four parameters are nodecluster name (couchbase-node, provider (aws, region (us-west-1 and nodetype (m3.large).
Each node in this node cluster will be given the assigned tag. This will be used later to assign services to a specific node or node cluster.
Status of this node cluster can be checked:

docker–nuvem nodecluster inspect 42a34e04–02e1–47be–bf87–ec06e0e0b604 | jq { “disk”: 60, “uuid”: “42a34e04-02e1-47be-bf87-ec06e0e0b604”, “tags”: [ { “nome”: “couchbase” } ], “current_num_nodes”: 1, “region”: “/api/infra/v1/region/aws/us-west-1/”, “target_num_nodes”: 1, “state”: “Deployed”, “node_type”: “/api/infra/v1/nodetype/aws/m3.large/”, “resource_uri”: “/api/infra/v1/nodecluster/42a34e04-02e1-47be-bf87-ec06e0e0b604/”, “destroyed_datetime”: null, “provider_options”: {}, “nodes”: [ “/api/infra/v1/node/5c4c78e0-71c9-4420-9a1d-fdb04a35d1de/” ], “deployed_datetime”: “Tue, 15 Mar 2016 17:18:17 +0000”, “nickname”: “couchbase-node”, “dockercloud_action_uri”: “”, “nome”: “couchbase-node” } |
The dashboard at cloud.docker.com is updated to show: 
More information about each node can be seen as well: 
Create a new Docker Cloud Service
Create a Docker Cloud Service:
|
1 2 |
docker–nuvem service criar —tag Couchbase –p 8091:8091 –p 8092:8092 –p 8093:8093 –p 11210:11210 arungupta/Couchbase 936dbe58–7c7c–4289–837a–15d29128e5ea |
If multiple node clusters exists, then --tag is used to assign a service to a node cluster. docker-cli#10 is filed to ensure multiple ports can be exposed using -p 8091-8093:8091-8093 format. This will be aligned with the docker CLI.
Docker image used here is arungupta/couchbase. This image is based on the official Couchbase image at Docker Hub e pre-configures it for different services.
Start the Docker Cloud Service:

docker–nuvem service start 834343fd–b1d5–4d66–a2cd–69d27a471658 834343fd–b1d5–4d66–a2cd–69d27a471658 |

Access Couchbase Server in Docker Cloud
Inspect the Docker Cloud service for the exposed container ports:
0
To be more specific, exact URI for the Console da Web do Couchbase can be obtained as:
1
Access the Couchbase Web Console at https://couchbase-b9132b42.936dbe58.svc.dockerapp.io:8091/ to see the Couchbase Web Console login screen. Enter the password credentials of Administrador e senha. 
And the Console da Web do Couchbase looks like:
