# How to maintain this repository

The structure and usage of this repository is influenced by other, official docker repositories.

# Version directories

**This is important!**

Never ever change a file/folder inside a directory without a `.` at the beginning (`2018.05-rc`, ...).
This folder will get updated automatically based on the templates you want to change.
All changes in such folders will get overwritten during an update.

# Maintenance scripts

# `update.sh`
   
Creates a directory and the necessary files for each combination of version (2018.05-rc, 3.6, ...) and variant (apache, fpm, fpm-alpine):

- Creating the right `Dockerfile` (from one of the two *.template files)
- Copy each shell and *.exclude file in `.docker-files/`
- Recreating the version/variant environment in `.travis.yml` 
   
If you want to update the Docker-images to a newer version, just change the list in `update.sh` at
```shell
versions=(
  2018.05-rc
)
```
   
# `generate-stackbrew-library.sh`
   
This file automatically creates a "manifest" for the docker-images.
Like:

```console

# `build_and_push.sh`

This file automatically builds and publish all docker image variants (apache, fpm, ...) and versions (stable, latest, dev, ...)

It uses [bashbrew](https://github.com/docker-library/official-images/tree/master/bashbrew) for building and publishing and `generate-stackbrew-library.sh` for the definition (manifest) what to build and publish.

See [Instruction format](https://github.com/docker-library/official-images/blob/master/README.md#instruction-format) for more background information.
