Client Image
Usually the Airnode is deployed on a serverless platform using the deployer. However, there is another option which is to run the Airnode in a docker container on your machine locally, on premise or cloud hosted.
A docker client image has been published on Docker Hub. If you want to build the container from the source yourself, you can find the image and built instructions in the Airnode repository.
Configuration
The Airnode needs two configuration files for its run: config.json
and secrets.env
. These files need to be passed to the Docker container via volumes.
The Docker container looks for configuration files mounted internally in the /app/config
directory.
Your current working directory should contain the configuration files above and you bind it to the /app/config
directory for the docker using the --volume
parameter.

Usage
Example directory structure and commands for running the Airnode Docker container. The below commands are run from the depicted directory.
Running Airnode
Use the following command to run Airnode:
docker run \
--volume $(pwd):/app/config \
--name airnode \
api3/airnode-client:0.15.0

If you want to connect Airnode to a blockchain running on localhost, you need to make the blockchain accessible from within the docker itself. If you use docker for linux you can use
--network="host"
parameter. If you are using Docker Desktop (on any platform), connect tohttp://host.docker.internal:8545
instead ofhttp://127.0.0.1:8545
. See https://stackoverflow.com/a/24326540.
Checking Airnode logs
Logs will be output to the console after running the above command. If you decide to run Airnode in detached mode with --detach
, you need to use the logs
command, optionally with --follow
, to access the logs.
docker logs airnode
or
docker logs --follow airnode
Stopping Airnode
docker stop airnode
