+# Docker OS Images : COUCHBASE
+
+Simple container used to deliver distributed and low latency document oriented database
+Run [couchbase daemon](https://www.couchbase.org/) under a container 
+based on [startx/fedora container](https://hub.docker.com/r/startx/fedora)
+
+| [![Build Status](https://travis-ci.org/startxfr/docker-images.svg)](https://travis-ci.org/startxfr/docker-images) | [Dockerhub Registry](https://hub.docker.com/r/startx/sv-couchbase/) | [Sources](https://github.com/startxfr/docker-images/Services/couchbase)             | [STARTX Profile](https://github.com/startxfr) | 
+|-------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------|------------------------------------------------------------------------------------|-----------------------------------------------|
+
+## Available flavours
+
+* `:latest` : Fedora core 23 + couchbase 1.4.17 
+* `:fc23` : Fedora core 23 + couchbase 1.4.17
+* `:centos7` : CentOS 7 + couchbase
+
+## Running from dockerhub registry
+
+* with `docker` you can run `docker run -it --name="service-couchbase" startx/sv-couchbase` from any docker host
+* with `docker-compose` you can create a docker-compose.yml file with the following content
+```
+service:
+  image: startx/sv-couchbase:latest
+  container_name: "service-couchbase"
+  environment:
+    CONTAINER_TYPE: "service"
+    CONTAINER_SERVICE: "couchbase"
+    CONTAINER_INSTANCE: "service-couchbase"
+  volumes:
+    - "/tmp/container/logs/couchbase:/data/logs/couchbase"
+```
+
+## Docker-compose in various situations
+
+* sample docker-compose.yml linked to host port 1000
+```
+service:
+  image: startx/sv-couchbase:latest
+  container_name: "service-couchbase"
+  environment:
+    CONTAINER_INSTANCE: "service-couchbase"
+  ports:
+    - "1000:11211"
+```
+* sample docker-compose.yml with port exposed only to linked services
+```
+service:
+  image: startx/sv-couchbase:latest
+  container_name: "service-couchbase"
+  environment:
+    CONTAINER_INSTANCE: "service-couchbase"
+  expose:
+    - "11211"
+```
+
+## Using this image in your own container
+
+You can use this Dockerfile template to start a new personalized container based on this container. Create a file named Dockerfile in your project directory and copy this content inside. See [docker guide](http://docs.docker.com/engine/reference/builder/) for instructions on how to use this file.
+ ```
+FROM startx/sv-couchbase:latest
+#... your container specifications
+CMD ["/bin/run.sh"]
+```
+
+## Environment variable
+
+| Variable                  | Type     | Mandatory | Description                                                              |
+|---------------------------|----------|-----------|--------------------------------------------------------------------------|
+| CONTAINER_INSTANCE        | `string` | `yes`     | Container name. Should be uning to get fine grained log and application reporting
+| CONTAINER_TYPE            | `string` | `no`      | Container family (os, service, application. could be enhanced 
+| CONTAINER_SERVICE         | `string` | `no`      | Define the type of service or application provided
+| HOSTNAME                  | `auto`   | `auto`    | Container unique id automatically assigned by docker daemon at startup
+| LOG_PATH                  | `auto`   | `auto`    | default set to /data/logs/couchbase and used as a volume mountpoint
+
+## Exposed port
+
+| Port  | Description                                                              |
+|-------|--------------------------------------------------------------------------|
+| 11211 | standard couchbase network port used for key/value recovery
+
+## Exposed volumes
+
+| Container directory  | Description                                                              |
+|----------------------|--------------------------------------------------------------------------|
+| /data/logs/couchbase  | log directory used to record container and couchbase logs
+| /data/couchbase       | data directory served by couchbase. If empty will be filled with app on startup. In other case use content from mountpoint or data volumes
+
+## Testing the service
+
+access to the running couchbase daemon with `telnet localhost 11211; stats`. Change port and hostname according to your current configuration
+
+## For advanced users
+
+You want to use this container and code to build and create locally this container, follow theses instructions.
+
+This section will help you if you want to :
+* Get latest version of this service container
+* Enhance container content by adding instruction in Dockefile before build step
+
+You must have a working environment with the source code of this repository. Read and follow [how to setup your working environment](https://github.com/startxfr/docker-images#setup-your-working-environment-mandatory) to get a working directory. The following instructions assume you are at the top level of your working directory.
+
+### Build & run a container using `docker`
+
+1. Jump into the container directory with `cd Services/couchbase`
+2. Build the container using `docker build -t sv-couchbase .`
+3. Run this container 
+  1. Interactively with `docker run -p 11211:11211 -v /data/logs/couchbase -it sv-couchbase`. If you add a second parameter (like `/bin/bash`) to will run this command instead of the default entrypoint. Usefull to interact with this container (ex: `/bin/bash`, `/bin/ps -a`, `/bin/df -h`,...) 
+  2. As a daemon with `docker run -p 11211:11211 -v /data/logs/couchbase -d sv-couchbase`
+
+
+### Build & run a container using `docker-compose`
+
+1. Jump into the container directory with `cd Services/couchbase`
+2. Run this container 
+  1. Interactively with `docker-compose up` Startup logs appears and escaping this command stop the container
+  2. As a daemon with `docker-compose up -d`. Container startup logs can be read using `docker-compose logs`
+
+If you experience trouble with port already used, edit docker-compose.yml file and change port mapping
