Docker

Run Howland on a machine with no screen.

5.1Run Howland in Docker

The image does not include the models; install them in 5.2.

docker run -d --name howland \
  -p 127.0.0.1:31050-31053:31050-31053 \
  -v howland-data:/data \
  ayerselectronics/howland:1.0.0

Open http://localhost:31052 in a browser on the Docker host.

5.2Install the models

Check free disk space first.

docker exec howland howland-setup install --yes

Check

Howland responds in the browser and finds its models.

5.3Allow other devices to connect

The loopback binding above limits access to the Docker host. To serve your local network, replace 127.0.0.1 with the host's trusted LAN address and recreate the container using the same data volume.

Use host firewall rules to limit access to the intended network. Do not forward these ports to the public internet.

5.4Operate and inspect

docker logs howland
docker stop howland
docker start howland

Keep the howland-data volume when replacing the container, and back it up before upgrading.

For a computer with a desktop, see Installation.
