## Introduction
This is a Dockerfile to build a container image for nginx and php-fpm, with the ability to pull website code from git. The container also has the ability to update templated files with variables passed to docker in order to update your settings. There is also support for lets encrypt SSL support.
## Overview
This is a Dockerfile/image to build a container for nginx and php-fpm, with the ability to pull website code from git when the container is created, as well as allowing the container to push and pull changes to the code to and from git. The container also has the ability to update templated files with variables passed to docker in order to update your code and settings. There is support for lets encrypt SSL configurations, custom nginx configs, core nginx/PHP variable overrides for running preferences, X-Forwarded-For headers and UID mapping for local volume support.

## Building from source
To build from source you need to clone the git repo and run docker build:
```
git clone https://github.com/ngineered/nginx-php-fpm
.git
docker build -t nginx-php-fpm:latest .
```
## Pulling from Docker Hub
```
docker pull richarvey/nginx-php-fpm
```
## Running
To simply run the container:
```
sudo docker run -d richarvey/nginx-php-fpm
```
You can then browse to ```http://<DOCKER_HOST>``` to view the default install files. To find your ```DOCKER_HOST``` use the ```docker inspect``` to get the IP address (normally 172.17.0.2)

To pull code from git when running:
```
docker run -d -e 'GIT_EMAIL=email_address' -e 'GIT_NAME=full_name' -e 'GIT_USERNAME=git_username' -e 'GIT_REPO=github.com/project' -e 'GIT_PERSONAL_TOKEN=<long_token_string_here>' richarvey/nginx-php-fpm:latest

## Documentation
### Dynamically Pulling code from git
One of the nice features of this container is its ability to pull code from a git repository with a couple of environmental variables passed at run time. Please take a look at our recommended [repo layout guidelines](https://github.com/ngineered/nginx-php-fpm/blob/master/docs/repo_layout.md).
There are two methods of pulling code from git, you can either use a Personal Token (recommended method) or an SSH key.
**Note:** We would recommend using a git personal token over an SSH key as it simplifies the set up process. To create a personal access token on Github follow this [guide](https://help.github.com/articles/creating-an-access-token-for-command-line-use/).
#### Personal Access token
You can pass the container your personal access token from your git account using the __GIT_PERSONAL_TOKEN__ flag. This token must be setup with the correct permissions in git in order to push and pull code.
Since the access token acts as a password with limited access, the git push/pull uses HTTPS to authenticate. You will need to specify your __GIT_USERNAME__ and __GIT_PERSONAL_TOKEN__ variables to push and pull. You'll need to also have the __GIT_EMAIL__, __GIT_NAME__ and __GIT_REPO__ common variables defined.
```
docker run -d -e 'GIT_EMAIL=email_address' -e 'GIT_NAME=full_name' -e 'GIT_USERNAME=git_username' -e 'GIT_REPO=github.com/project' -e 'GIT_PERSONAL_TOKEN=<long_token_string_here>' richarvey/nginx-php-fpm:latest
```
To pull a repository and specify a branch add the __GIT_BRANCH__ environment variable:
```
docker run -d -e 'GIT_EMAIL=email_address' -e 'GIT_NAME=full_name' -e 'GIT_USERNAME=git_username' -e 'GIT_REPO=github.com/project' -e 'GIT_PERSONAL_TOKEN=<long_token_string_here>' -e 'GIT_BRANCH=stage' richarvey/nginx-php-fpm:latest
```
#### SSH keys
##### Preparing your SSH key
The container has the option for you to pass it the __SSH_KEY__ variable with a **base64** encoded **private** key. First generate your key and then make sure to add it to github and give it write permissions if you want to be able to push code from the container. Then run:
```
base64 -w 0 /path_to_your_private_key
```
**Note:** Copy the output, but be careful not to copy your prompt
##### Running with SSH Keys
To run the container and pull code simply specify the GIT_REPO URL including *git@* and then make sure you have also supplied your base64 version of your ssh deploy key:
```
sudo docker run -d -e 'GIT_NAME=full_name' -e 'GIT_USERNAME=git_username' -e 'GIT_REPO=github.com/project' -e 'SSH_KEY=BIG_LONG_BASE64_STRING_GOES_IN_HERE' richarvey/nginx-php-fpm:latest
```
To pull a repository and specify a branch add the GIT_BRANCH environment variable:
```
sudo docker run -d -e 'GIT_NAME=full_name' -e 'GIT_USERNAME=git_username' -e 'GIT_REPO=github.com/project' -e 'SSH_KEY=BIG_LONG_BASE64_STRING_GOES_IN_HERE' -e 'GIT_BRANCH=stage' richarvey/nginx-php-fpm:latest
```
### User / Group Identifiers
Sometimes when using data volumes (`-v` flags) permissions issues can arise between the host OS and the container. We avoid this issue by allowing you to specify the user `PUID` and optionally the group `PGID`. Ensure the data volume directory on the host is owned by the same user you specify and it will "just work" ™.
An example of mapping the UID and GID to the container is as follows:
```
docker run -d -e "PUID=`id -u $USER`" -e "PGID=`id -g $USER`" -v local_dir:/var/www/html richarvey/nginx-php-fpm:latest
```
This will pull your local UID/GID and map it into the container so you can edit on your host machine and the code will still run in the container.
### Custom Nginx Config files
Sometimes you need a custom config file for nginx to achieve this read the [Nginx config guide](https://github.com/ngineered/nginx-php-fpm/blob/master/docs/nginx_configs.md)
#### REAL IP / X-Forwarded-For Headers
If you operate your container behind a load balancer, an ELB on AWS for example, you need to configure nginx to get the real IP and not the load balancer IP in the logs by using the X-Forwarded-For. We've provided some handy flags to let you do this. You need to set both of these to get this to work:
```
-e "REAL_IP_HEADER=1"
-e "REAL_IP_FROM=Your_CIDR"
```
For example:
```
docker run -d -e "REAL_IP_HEADER=1" -e "REAL_IP_FROM=10.1.0.0/16" richarvey/nginx-php-fpm:latest
```
### Scripting and Templating
Please see the [Scripting and templating guide](https://github.com/ngineered/nginx-php-fpm/blob/master/docs/scripting_templating.md) for more details.
### Lets Encrypt support
This container includes support to easily manage lets encrypt certificates. Please see the [Lets Encrypt guide](https://github.com/ngineered/nginx-php-fpm/blob/master/docs/lets_encrypt.md) for more details.
### Install PHP Modules
First of all drop into the container:
```
docker exec -t -i nginx /bin/bash
```
Then configure and install your module:
```
/usr/local/bin/docker-php-ext-configure sockets
/usr/local/bin/docker-php-ext-install sockets
```
Now restart php-fpm:
```
supervisorctl restart php-fpm
```
## Special Git Features
Specify the ```GIT_EMAIL``` and ```GIT_NAME``` variables for this to work. They are used to set up git correctly and allow the following commands to work.
### Push code to Git
To push code changes made within the container back to git run:
```
sudo docker exec -t -i <CONTAINER_NAME> /usr/bin/push
```
### Pull code from Git (Refresh)
In order to refresh the code in a container and pull newer code from git run:
```
sudo docker exec -t -i <CONTAINER_NAME> /usr/bin/pull
```
## Logging and Errors
### Logging
All logs should now print out in stdout/stderr and are available via the docker logs command:
```
docker logs <CONTAINER_NAME>
```
### WebRoot
You can set your webroot in the container to anything you want using the ```WEBROOT``` variable e.g -e "WEBROOT=/var/www/html/public". By default code is checked out into /var/www/html/ so if your git repository does not have code in the root you'll need to use this variable.
