# Docker OS Images : APACHE + PHP

Simple container used to deliver dynamic http content using apache associated with PHP engine
Run [PHP engine](https://www.php.net) under a container 
based on [startx/sv-apache container](https://hub.docker.com/r/startx/sv-apache)

## Running from dockerhub registry

* with `docker` you can run `docker run -it --name="service-php" startx/sv-php` from any docker host
* with `docker-compose` you can create a docker-compose.yml file with the following content
```
service:
  image: startx/sv-php:latest
  container_name: "service-php"
  environment:
    CONTAINER_TYPE: "service"
    CONTAINER_SERVICE: "php"
    CONTAINER_INSTANCE: "service-php"
    SERVER_NAME: "localhost"
    DOC_ROOT: "/data/apache_php"
  volumes:
    - "/tmp/container/logs/php:/data/logs/apache_php"
    - "/tmp/container/php:/data/apache_php"
```

## Docker-compose in various situations

* sample docker-compose.yml linked to host port 1000
```
service:
  image: startx/sv-php:latest
  container_name: "service-php"
  environment:
    CONTAINER_INSTANCE: "service-php"
  ports:
    - "1000:80"
```
* sample docker-compose.yml with port exposed only to linked services
```
service:
  image: startx/sv-php:latest
  container_name: "service-php"
  environment:
    CONTAINER_INSTANCE: "service-php"
  expose:
    - "80"
```
* sample docker-compose.yml using data container
```
data:
  image: startx/fedora:latest
  container_name: "service-php-data"
  environment:
    CONTAINER_INSTANCE: "service-php-data"
service:
  image: startx/sv-php:latest
  container_name: "service-php"
  environment:
    CONTAINER_INSTANCE: "service-php"
  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-php:latest
#... your container specifications
CMD ["/bin/run.sh"]
```

## Testing the service

access to the running webserver with your favorites browser `firefox http://localhost:80`. 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/php`
2. Build the container using `docker build -t sv-php .`
3. Run this container 
  1. Interactively with `docker run -p 80:80 -v /data/logs/apache_php -it sv-php`. 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 80:80 -v /data/logs/apache_php -d sv-php`


### Build & run a container using `docker-compose`

1. Jump into the container directory with `cd Services/php`
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
