When you have appdaemon installed by either method, copy the conf/appdaemon.cfg.example file to conf/appdaemon.cfg, then edit the [AppDaemon] section to reflect your environment:

[AppDaemon]
ha_url = <some_url>
ha_key = <some key>
logfile = STDOUT
errorfile = STDERR
app_dir = <Path to appdaemon dir>/conf/apps
threads = 10
latitude = <latitude>
longitude = <longitude>
elevation = <elevation
timezone = <timezone>
cert_path = <path/to/root/CA/cert>
# Apps
[hello_world]
module = hello
class = HelloWorld

• ha_url is a reference to your Home Assistant installation and must include the correct port number and scheme (http:// or https:// as appropriate)
• ha_key should be set to your key if you have one, otherwise it can be removed.
• logfile (optional) is the path to where you want AppDaemon to keep its main log. When run from the command line this is not used - log messages come out on the terminal. When running as a daemon this is where the log information will go. In the example above I created a directory specifically for AppDaemon to run from, although there is no reason you can't keep it in the appdaemon directory of the cloned repository. If logfile = STDOUT, output will be sent to stdout instead of stderr when running in the foreground, if not specified, output will be sent to STDOUT.
• errorfile (optional) is the name of the logfile for errors - this will usually be errors during compilation and execution of the apps. If errorfile = STDERR errors will be sent to stderr instead of a file, if not specified, output will be sent to STDERR.
• app_dir (optional) is the directory the apps are placed in. If not specified, AppDaemon will look first in ~/.homeassistant then /etc/appdaemon for a subdirectory named apps
• threads - the number of dedicated worker threads to create for running the apps. Note, this will bear no resemblance to the number of apps you have, the threads are re-used and only active for as long as required to tun a particular callback or initialization, leave this set to 10 unless you experience thread starvation
• latitude, longitude, elevation, timezone - should all be copied from your Home Assistant configuration file
• cert_path (optional) - path to root CA cert directory - use only if you are using self signed certs.

The #Apps section is the configuration for the Hello World program and should be left in place for initial testing but can be removed later if desired, as other Apps are added, App configuration is described in the API doc.

For Docker Configuration you need to take a couple of extra things into consideration.

Our Docker image is designed to load your configuration and apps from a volume at /conf so that you can manage them in your own git repository, or place them anywhere else on the system and map them using the Docker command line.

For example, if you have a local repository in /Users/foo/ha-config containing the following files:

$ git ls-files
configuration.yaml
customize.yaml
known_devices.yaml
appdaemon.cfg
apps
apps/magic.py

You will need to modify the appdaemon.cfg file to point to these apps in /conf/apps:

[AppDaemon]
ha_url = <some_url>
ha_key = <some key>
logfile = STDOUT
errorfile = STDERR
app_dir = /conf/apps
threads = 10
latitude = <latitude>
longitude = <longitude>
elevation = <elevation
timezone = <timezone>

You can run Docker and point the conf volume to that directory.
