|
|
|
|
This project contains all sources to build the container image
|
|
`docker.io/volkerraschek/fetchmail`. The primary goal of the image is to fetch
|
|
mails from external servers and forward them to on local running mail server.
|
|
|
|
The configuration file will be automatically generated based on information from
|
|
a supported database backend of
|
|
[postfixadmin](https://github.com/postfixadmin/postfixadmin). The information
|
|
are stored in the table `fetchmail` of the database scheme of PostfixAdmin.
|
|
|
|
## Usage
|
|
|
|
Possible database types are `my` for MySQL and `Pg` for postgres. Make sure that
|
|
the database and the SMTP server are accessible. Otherwise, adjust the enclosed
|
|
docker-compose or docker command accordingly. Alternatively you can use
|
|
docker-compose in addition to the docker commands.
|
|
|
|
### PostgreSQL
|
|
|
|
```bash
|
|
$ docker run \
|
|
--rm \
|
|
--env DATABASE_TYPE: Pg \
|
|
--env DATABASE_HOST: postgres \
|
|
--env DATABASE_PORT: 5432 \
|
|
--env DATABASE_NAME: postgres \
|
|
--env DATABASE_USER: fetchmail \
|
|
--env DATABASE_PASSWORD: MySecretPassword \
|
|
--network host \
|
|
volkerraschek/fetchmail:latest
|
|
```
|
|
|
|
### MySQL
|
|
|
|
```bash
|
|
$ docker run \
|
|
--rm \
|
|
--env DATABASE_TYPE: my \
|
|
--env DATABASE_HOST: root \
|
|
--env DATABASE_PORT: 3306 \
|
|
--env DATABASE_NAME: mysql \
|
|
--env DATABASE_USER: fetchmail \
|
|
--env DATABASE_PASSWORD: MySecretPassword \

### docker-compose
|
|
|
|
The repository contains a default `docker-compose.yml` file, which can be used
|
|
to start the container. To set the environment variables you need a `.env` file.
|
|
The `.dev_env` from this repository can be used for this. This must be located
|
|
exclusively in the same directory as the `docker-compose.yml` file and must be
|
|
renamed as `.env`.
|
|
|
|
```yml
|
|
version: "3"
|
|
services:
|
|
fetchmail:
|
|
image: volkerraschek/fetchmail:latest
|
|
environment:
|
|
