======

|
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`
