# docker-ttrss
|
||||
|
||||
This docker image allows you to run the [Tiny Tiny RSS](http://tt-rss.org) feed reader.
|
||||
Keep your feed history to yourself and access your RSS and atom feeds from everywhere.
|
||||
You can access it through an easy to use webinterface on your desktop, your mobile browser
|
||||
or using one of available apps.
|
||||
|
||||
## Instructions
|
||||
|
||||
```bash
|
||||
$ git clone https://github.com/clue/docker-ttrss.git
|
||||
$ cd docker-ttrss
|
||||
$ sudo docker build -t ttrss .
|
||||
```
|
||||
|
||||
### Running
|
||||
|
||||
Following docker's best practices, this container does not contain its own database,
|
||||
but instead expects you to supply a running instance.
|
||||
While slightly more complicated at first, this gives your more freedom as to which
|
||||
database instance and configuration you're relying on.
|
||||
Also, this makes this container quite disposable, as it doesn't store any sensitive
|
||||
information at all.
|
||||
|
||||
#### Starting a database instance
|
||||
|
||||
This container requires a PostgreSQL database instance. You're free to pick (or build)
|
||||
any, as long as is exposes its database port (5432) to the outside.
|
||||
|
||||
Example:
|
||||
|
||||
```bash
|
||||
$ sudo docker pull nornagon/postgres
|
||||
$ sudo docker run -d --name=tinystore nornagon/postgres
|
||||
```
|
||||
|
||||
#### Testing ttrss in foreground
|
||||
|
||||
For testing purposes it's recommended to initially start this container in foreground.
|
||||
This is particular useful for your initial database setup, as errors get reported to
|
||||
the console and further execution will halt.
|
||||
|
||||
```bash
|
||||
$ sudo docker run -it --link tinystore:db -p 80:80 ttrss
|
||||
```
|
||||
|
||||
##### Database configuration
|
||||
|
||||
Whenever your run ttrss, it will check your database setup. It assumes the following
|
||||
default configuration, which can be changed by passing the following additional arguments:
|
||||
|
||||
```
|
||||
-e DB_NAME=ttrss
|
||||
-e DB_USER=ttrss
|
||||
-e DB_PASS=ttrss
|
||||
```
|
||||
|
||||
##### Database superuser
|
||||
|
||||
When you run ttrss, it will check your database setup. If it can not connect using the above
|
||||
configuration, it will automatically try to create a new database and user.
|
||||
|
||||
For this to work, it will need a superuser account that is permitted to create a new database
|
||||
and user. It assumes the following default configuration, which can be changed by passing the
|
||||
following additional arguments:
|
||||
|
||||
```
|
||||
-e DB_ENV_USER=docker
|
||||
-e DB_ENV_PASS=docker
|
||||
```
|
||||
|
||||
#### Running ttrss daemonized
|
||||
|
||||
Once you've confirmed everything works in the foreground, you can start your container
|
||||
in the background by replacing the `-it` argument with `-d` (daemonize).
|
||||
Remaining arguments can be passed just like before, the following is the recommended
|
||||
minimum:
|
||||
|
||||
```bash
|
||||
$ sudo docker run -d --link tinystore:db -p 80:80 ttrss
|
||||
```
|
||||
|
||||
### Accessing your webinterface
|
||||
|
||||
The above examples expose the Tiny Tiny RSS webinterface on port 80, so that you can browse to:
|
||||
|
||||
http://localhost/
|
||||
|
||||
The default login credentials are:
|
||||
|
||||
Username: admin
|
||||
Password: password
|
||||
|
||||
Obviously, you're recommended to change those ASAP.
