Create a Docker-Compose App¶

In the Configuring Git section, you should have set up git with your auth token, meaning you can clone your Factory repositories from https://source.foundries.io/factories/<factory>/ and begin creating new targets for your devices to update to.

Example Apps¶

This default example shows how apps are enabled. You should read the contents of the shellhttpd folder to see how this application has been defined, or read the other examples to learn how you can define an app from scratch.

Clone your containers.git repo and enter it:

git clone https://source.foundries.io/factories/<factory>/containers.git
cd containers.git

We initialise your containers.git repository with a simple compose app example in shellhttpd.disabled/

Tip

Directory names ending with .disabled in containers.git are ignored by our CI system.

Enable the shellhttpd example app:
```
mv shellhttpd.disabled shellhttpd
```

Add, commit and push:

git add .
git commit -m "shellhttpd: enable shellhttpd app"
git push

Watch Your Build

When changes are made to containers.git in your Factory sources, a new target is built by our CI system. Devices that are registered to your Factory will be able to see this target and conditionally update to it, depending on their device configuration.

Device Configuration

Now that a target is being built, we want to tell our device(s) to update to this new target. This is done using Fioctl.

Determine the device you want to configure to use shellhttpd:

fioctl devices list

your output should look like this:

NAME  FACTORY  OWNER           TARGET                  STATUS  APPS  UP TO DATE
----  -------  -----           ------                  ------  ----  ----------
foo   gavin    <unconfigured>  raspberrypi3-64-lmp-19  OK            true

Configure the device to run the shellhttpd app. Make sure to replace <device> with the NAME of yours:
```
fioctl devices config updates <device> --apps shellhttpd
```

This example describes how to create a docker-compose app for the Mosquitto MQTT Broker from scratch.

Clone your containers.git repo and enter it. Make sure to replace <factory> in the example with the name of your Factory:
```
git clone https://source.foundries.io/factories/<factory>/containers.git
cd containers.git
```
Create a directory named mosquitto and cd into it. This folder name defines the name of the container image that will be pulled on your device from hub.foundries.io:
```
mkdir mosquitto
cd mosquitto
```
Create a file named Dockerfile to describe your container, with the following contents:
```
FROM eclipse-mosquitto:latest
```
Create a file named docker-compose.yml to describe how you want this container to run, with the following contents. Make sure to replace <factory> in the example below with the name of your Factory:
```
version: "3.2"

services:
  mosquitto:
    restart: always
    image: hub.foundries.io/<factory>/mosquitto:latest
    ports:
      - "1883:1883"
```

Add, commit and push:

git add .
git commit -m "mosquitto: create mosquitto container"
git push

----  -------  -----           ------                  ------  ----  ----------
foo   gavin    <unconfigured>  raspberrypi3-64-lmp-19  OK            true

Configure the device to run the mosquitto app. Make sure to replace <device> with the NAME of yours:
```
fioctl devices config updates <device> --apps mosquitto
```

About Targets¶

You can see the available targets your Factory has produced:

fioctl targets list

CLI Output:

VERSION  TAGS    APPS        HARDWARE IDs
-------  ----    ----        ------------
2        devel               raspberrypi3-64
3        master              raspberrypi3-64
4        master  shellhttpd  raspberrypi3-64

details about target can be printed by passing its version number to the show subcommand:

fioctl targets show 4

CLI Output:

Completion¶

Now that you’re done, you might want to read Tutorials to see some examples of the things that can be done with your Factory. Additionally, you can read the Reference Manual to learn more about the architecture of FoundriesFactory and the Linux microPlatform.
