# Guide for running on docker
|
||||
|
||||
## Host system
|
||||
This guide will assume an updated installation of Debian bullseye (11), it should work on a lot of different linux OS and architectures.<br>
|
||||
You will need to install the libraries and supporting sw/fw for your sdr device, including udev rules and blacklists.<br>
|
||||
Additional software such as soapysdr is not needed on the host, but can certainly be installed.<br>
|
||||
```shell
|
||||
sudo apt install rtl-sdr
|
||||
echo "blacklist dvb_usb_rtl28xxu" | sudo tee /etc/modprobe.d/blacklist-rtlsdr.conf
|
||||
sudo modprobe -r dvb_usb_rtl28xxu
|
||||
```
|
||||
|
||||
See the [docker installation](#install-dockerio) at the bottom of this page.
|
||||
|
||||
## Building the image
|
||||
If the docker image is not available, or you want to build from your own branch etc.
|
||||
```shell
|
||||
git clone https://github.com/projecthorus/horusdemodlib.git
|
||||
cd horusdemodlib
|
||||
docker-compose build
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Start with creating a directory with a name representing the station, this will be shown in several places in the resulting stack.
|
||||
```shell
|
||||
mkdir -p projecthorus
|
||||
cd projecthorus
|
||||
wget https://raw.githubusercontent.com/projecthorus/horusdemodlib/master/docker-compose.yml
|
||||
wget -O user.cfg https://raw.githubusercontent.com/projecthorus/horusdemodlib/master/user.cfg.example
|
||||
wget -O user.env https://raw.githubusercontent.com/projecthorus/horusdemodlib/master/user.env.example
|
||||
```
|
||||
|
||||
The file `user.env` contains all the station variables (earlier in each script), the DEMODSCRIPT is used by compose.<br>
|
||||
The `user.cfg` sets the details sent to Sondehub.<br>
|
||||
Use your favourite editor to configure these:
|
||||
```shell
|
||||
nano user.env
|
||||
nano user.cfg
|
||||
```
|
||||
Please note that the values in user.env should not be escaped with quotes or ticks.
|
||||
|
||||
## Bringing the stack up
|
||||
|
||||
The `docker-compose` (on some systems it's `docker compose` without the hyphen) is the program controlling the creation, updating, building and termination of the stack.
|
||||
The basic commands you will use is `docker-compose up` and `docker-compose down`.
|
||||
When you edit the compose file or configuration it will try to figure out what needs to be done to bring the stack in sync of what has changed.
|
||||
|
||||
Starting the stack in foreground (terminate with Ctrl-C):
|
||||
```shell
|
||||
docker-compose up
|
||||
```
|
||||
|
||||
Starting the stack in background:
|
||||
```shell
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
Stopping the stack:
|
||||
```shell
|
||||
docker-compose down
|
||||
```
|
||||
|
||||
Updating the images and bringing the stack up:
|
||||
```shell
|
||||
docker-compose pull
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
Over time there will be old images accumulating, these can be removed with `docker image prune -af`
|
||||
|
||||
## Using SoapySDR with rx_tools
|
||||
|
||||
If you want to use other SDR than rtl_sdr, the docker build includes rx_tools.<br>
|
||||
Select docker_soapy_single.sh and add the extra argument to select the sdr in SDR_EXTRA:
|
||||
```shell
|
||||
# Script name
|
||||
DEMODSCRIPT="docker_soapy_single.sh"
|
||||
SDR_EXTRA="-d driver=rtlsdr"
|
||||
```
|
||||
|
||||
## Monitoring and maintenance
|
||||
|
||||
Inside each container, the logs are output to stdout, which makes them visible from outside the container in the logs.
|
||||
Starting to monitor the running stack:
|
||||
```shell
|
||||
docker-compose logs -f
|
||||
```
|
||||
|
||||
If you want to run commands inside the containers, this can be done with the following command:
|
||||
````shell
|
||||
docker-compose exec horusdemod bash
|
||||
````
|
||||
The container needs to be running. Exit with Ctrl-D or typing `exit`.
|
||||
|
||||
# Install Docker.io
|
||||
(Or you can install Docker.com engine via the [convenience script](https://docs.docker.com/engine/install/debian/#install-using-the-convenience-script))
|
||||
|
||||
In Debian bullseye there's already a docker package, so installation is easy:
|
||||
```shell
|
||||
sudo apt install docker.io apparmor
|
||||
sudo apt -t bullseye-backports install docker-compose
|
||||
sudo adduser $(whoami) docker
|
||||
```
|
||||
Re-login for the group permission to take effect.
|
||||
|
||||
The reason for using backports is the version of compose in bullseye is 1.25 and lacks cgroup support, the backport is version 1.27
|
||||
<br>If your dist doesn't have backports, enable with this, and try the installation of docker-compose again:
|
||||
```shell
|
||||
echo "deb http://deb.debian.org/debian bullseye-backports main contrib non-free" | sudo tee /etc/apt/sources.list.d/backports.list
|
||||
suod apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 648ACFD622F3D138 0E98404D386FA1D9
|
||||
sudo apt update
|
||||
```
|
||||
If you cannot get a good compose version with your dist, please follow [the official guide](https://docs.docker.com/compose/install/linux/#install-the-plugin-manually).
