-
-## Build and run from local Dockerfile
-### Building docker image
-Copy sources in your docker host
-
- mkdir startx-docker-images;
- cd startx-docker-images;
- git clone https://github.com/startxfr/docker-images.git .
-
-Change configuration and personalize your base image. See sx/mariadb_run.sh to perform some usefull task against the database, especially importing sql script, adding users and changing passwords. See also example.sql for injecting sql content when creating container.
-
-Build the container
-
- docker build -t sv-mariadb Services/mariadb/
-
-### Running local image
-
- docker run -d -p 3306:3306 --name="mariadb" sv-mariadb
-
-## Accessing server
-get connection information's, use docker logs to see result and connection details
-
- docker logs mariadb
-
-access to the running database
-
- mysql -h localhost -p 3306
-

+
+## Running from dockerhub registry
+
+* with `docker` you can run `docker run -it --name="sv-mariadb" startx/sv-mariadb` from any docker host
+* with `docker-compose` you can create a docker-compose.yml file with the following content
+```
+service:
+ image: startx/sv-mariadb:latest
+ container_name: "sv-mariadb"
+ environment:
+ CONTAINER_TYPE: "service"
+ CONTAINER_SERVICE: "mariadb"
+ CONTAINER_INSTANCE: "service-mariadb"
+ MYSQL_ROOT_PASSWORD: "rootpassword"
+ MYSQL_USER: "user-test"
+ MYSQL_PASSWORD: "pwd-test"
+ MYSQL_DATABASE: "db_test"
+ volumes:
+ - "/tmp/container/logs/mariadb:/data/logs/mariadb"
+ - "/tmp/container/mariadb:/data/mariadb"
+```
+
+## Docker-compose in various situations
+
+* sample docker-compose.yml linked to host port 1000
+```
+service:
+ image: startx/sv-mariadb:latest
+ container_name: "sv-mariadb"
+ environment:
+ CONTAINER_INSTANCE: "service-mariadb"
+ ports:
+ - "1001:3306"
+```
+* sample docker-compose.yml with port exposed only to linked services
+```
+service:
+ image: startx/sv-mariadb:latest
+ container_name: "sv-mariadb"
+ environment:
+ CONTAINER_INSTANCE: "service-mariadb"
+ expose:
+ - "3306"
+```
+* sample docker-compose.yml using data container
+```
+data:
+ image: startx/fedora:latest
+ container_name: "sv-mariadb-data"
+ environment:
+ CONTAINER_INSTANCE: "service-mariadb-data"
+service:
+ image: startx/sv-mariadb:latest
+ container_name: "sv-mariadb"
+ environment:
+ CONTAINER_INSTANCE: "service-mariadb"
+ volume_from:
+ - data:rw
+```
+
+## 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-mariadb:latest
+#... your container specifications
+CMD ["/bin/run.sh"]
+```
+

+
+## Exposed volumes
+

+
+## Testing the service
+
+access to the running service with mysql terminal `mysql --host=localhost --port=3306 --user=<MYSQL_USER> --password=<MYSQL_PASSWORD>`. 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/mariadb`
+2. Build the container using `docker build -t sv-mariadb .`
+3. Run this container
+ 1. Interactively with `docker run -p 3306:3306 -v /data/logs/mariadb -it sv-mariadb`. 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 3306:3306 -v /data/logs/mariadb -d sv-mariadb`
+
+
+### Build & run a container using `docker-compose`
+
+1. Jump into the container directory with `cd Services/mariadb`
+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
