-# STARTX Services docker-images : MongoDB Server
-
-Container running mongod daemon under a fedora server
-
-## Running from docker registry
-
-	docker run -d -p 27017:27017 --name="mongo" startx/sv-mongo
-        # when used with a volume container (run data container, then run service)
-	docker run -d -v /var/lib/mongodb -v /var/log/mongodb --name mongo-data startx/sv-mongo  echo "Data container for mongodb"
-	docker run -d -p 27017:27017 --volumes-from mongo-data --name="mongo" startx/sv-mongo
-	when linked to another container
-	docker run -d --name="mongo" startx/sv-mongo
-	docker run -d -p 80:80 --name="php" --link mongo:mongo startx/sv-php
-
-## 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/mongod_run.sh to perform some usefull task against the database, especially importing sql script, adding users and changing passwords. See also mongodb.conf for configuring the mongo server running in the container.
-
-Build the container
-
-	docker build -t sv-mongo Services/mongo/
-
-### Running local image
-
-	docker run -d -p 27017:27017 --name="mongo" sv-mongo
-
-## Accessing server
-access to the running database
-
-	mongo -h localhost -p 27017
-
-access to the container itself
-
-	docker exec -it mongo /bin/bash

+# Docker OS Images : APACHE
+
+Simple and lightweight (120Mo) container used to deliver static http content include all apache's modules but no external languages engines (like php). For dynamic content, you should use our [sv-php service container](https://hub.docker.com/r/startx/sv-php)
+Run [apache httpd daemon](https://httpd.apache.org/) under a container based on [startx/fedora container](https://hub.docker.com/r/startx/fedora)

+
+## Running from dockerhub registry
+
+* with `docker` you can run `docker run -it --name="sv-apache" startx/sv-apache` from any docker host
+* with `docker-compose` you can create a docker-compose.yml file with the following content
+```
+service:
+  image: startx/sv-apache:latest
+  container_name: "sv-apache"
+  environment:
+    CONTAINER_TYPE: "service"
+    CONTAINER_SERVICE: "apache"
+    CONTAINER_INSTANCE: "service-apache"
+    SERVER_NAME: "localhost"
+    DOC_ROOT: "/data/apache"
+  volumes:
+    - "/tmp/container/logs/apache:/data/logs/apache"
+    - "/tmp/container/apache:/data/apache"
+```
+
+## Docker-compose in various situations
+
+* sample docker-compose.yml linked to host port 1000
+```
+service:
+  image: startx/sv-apache:latest
+  container_name: "sv-apache"
+  environment:
+    CONTAINER_INSTANCE: "service-apache"
+  ports:
+    - "1000:27017"
+```
+* sample docker-compose.yml with port exposed only to linked services
+```
+service:
+  image: startx/sv-apache:latest
+  container_name: "sv-apache"
+  environment:
+    CONTAINER_INSTANCE: "service-apache"
+  expose:
+    - "27017"
+```
+* sample docker-compose.yml using data container
+```
+data:
+  image: startx/fedora:latest
+  container_name: "sv-apache-data"
+  environment:
+    CONTAINER_INSTANCE: "service-apache-data"
+service:
+  image: startx/sv-apache:latest
+  container_name: "sv-apache"
+  environment:
+    CONTAINER_INSTANCE: "service-apache"
+  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-apache:latest
+#... your container specifications
+CMD ["/bin/run.sh"]
+```

+
+## Testing the service
+
+access to the running webserver with your favorites browser `firefox http://localhost:27017`. 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/apache`
+2. Build the container using `docker build -t sv-apache .`
+3. Run this container 
+  1. Interactively with `docker run -p 27017:27017 -v /data/logs/apache -it sv-apache`. 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 27017:27017 -v /data/logs/apache -d sv-apache`
+
+
+### Build & run a container using `docker-compose`
+
+1. Jump into the container directory with `cd Services/apache`
+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
