# 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)
| [](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
