📄 Description

Add gettext dependencies as we need envsubst command;
Modified s6's gitea setup script, instead of cp the template if no
app.ini exist, it will substitude the envvars and generate the new
app.ini;
Make /docker/etc/templates/app.ini a template contains environment
variables;

The following environment variable can be set:

APP_NAME: (default: Gitea: Git with a cup of tea)
APP_MODE: (default: dev)
[server]:
- SSH_DOMAIN: (default: localhost)
- HTTP_PORT: (default: 3000)
- ROOT_URL: (default: '')
- DISABLE_SSH: (default: false)
- SSH_PORT: (default: 22)
[database]:
- DB_TYPE: (default: sqlite3)
- DB_HOST: (default: localhost:3306)
- DB_NAME: (default: gitea)
- DB_USER: (default: root)
- DB_PASSWD: (default: ``)
[security]:
- INSTALL_LOCK: (default: true)
- SECRET_KEY: (default: JPuNRXxX2G)

With these environment variables available, user can easily run the docker image with minor modifications without creating an custom app.ini, such as:

$ docker run -d -p 3000:3000 \
    -e ROOT_URL=http://dev.example.com \
    -e DB_TYPE=mysql \
    -e DB_HOST=1.2.3.4:3306 \
    -e DB_USER=gitea \
    -e DB_PASSWD=Sup3rPassw0rd \
    -e SECRET_KEY=Sup3r3ecre7 \
    gitea/gitea:latest
