Docker
======
TOOLS ARE WRITTEN FOR TESTING AND TO SEE WHAT IT IS!
For this to work you will need the nifty docker tool [docker-compose].
The most simple setup will look like this:
```sh
./assemble_blocks.sh docker_gogs w_db option_db_mysql
docker-compose up
```
That's it. You have GoGS running in docker linked to a MySQL docker container.
Now visit http://localhost:3000/ and give details for the admin account an you're up and running.
How does it work
----------------
`./assemble_blocks.sh` will look in `blocks` for subdirectories.
In the subdirectories there are three relevant files: `Dockerfile` , `config` and `docker-compose` .
`Dockerfile` will be copied to `docker/` (also means last `Dockerfile` wins).
The `config` file contains lines which will in the gogs docker container end up in `$GOGS_PATH/custom/config/app.ini` and by this gogs will be configured.
Here you can define things like the MySQL server for your database block.
The `docker-compose` file will just be added to `docker-compose.yml` , which is used by docker-compose to manage your containers.
This includes container linking!
Just have a look at them and it will be clear how to write your own blocks.
Just some things
- all files (`Dockerfile`, `docker-compose` and `config` ) are optional
- the gogs block should always be the first block
Currently the blocks are designed that, the blocks that start with `docker` pull in the base docker image.
Then one block starting with `w` defines, what containers should be linked to the gogs container.
For every option in the `w` block you need to add an `option` container.
Example:
```sh
./assemble_blocks.sh docker_gogs w_db_cache option_db_mysql option_cache_redis
```
More sophisticated Example
--------------------------
Here is a more elaborated example
```sh
./assemble_blocks.sh docker_gogs w_db_cache_session option_db_postgresql option_cache_redis option_session_mysql
docker-compose up
```
This will set up four containters and link them proberly. One for each of
docker-compose
- session (mysql)
WARNING: This will not work at the Moment! MySQL session is broken!
Remark
------
After you execute `assemble_blocks.sh` you should always trigger `docker-compose build` to inculde the the new init script `init_gogs.sh` in the docker image.
If you want to use another GoGS docker file, but keep everything else the same, you can create a block, e.g. `docker_gogs_custom` , with only a `Dockerfile` and call
```sh
./assemble_blocks.sh docker_gogs_custom w_db option_database_mysql
```
This will pull in the `Dockerfile` from `docker_gogs` instead of the one from `docker_gogs` .
`Dockerfile` s for the `master` and `dev` branch are provided as `docker_gogs` and `docker_gogs_dev`
