Docker Deployment

Running Lires with docker provide another level of isolation and security.

Basic usage

Start

# build the image
docker build -f docker/Dockerfile -t lires:runtime .

# run the container, map the port 8080 to the host machine port 80
docker run -d -p 80:8080 -v </path/to/data>:/root/.Lires --name lrs lires:runtime

Now you can access the web interface at http://localhost.

Management

# user management
docker exec -it lrs lrs-user ...

# check the logs
docker exec -it lrs lrs-log ...

# or check output by docker logs
docker logs -f lrs

Change the configuration

The docker image essentially runs the lrs-cluster command with the configuration file /root/.Lires/container-cluster.yaml. Which should be mounted to the host machine for easy access and modification.

INFO

Although you may change the environment variables with docker run -e ..., it is recommended to modify them in the cluster configuration file, to make sure it will not be overwritten by the values set with the configuration file.

Limit the resources

An advantage of running the app with docker is that you can limit the resources of the container.

To limit the memory and cpu usage, you can use the --memory and --cpus flags.

docker run --memory 4g --cpus 2 ...

To limit the disk usage, you can use the docker volume driver, for example, first create a volume with limited size, then mount it to the container.

# create a volume with 10G size
docker volume create --driver local --opt type=btrfs --opt o=size=10G lrs-data

# run the container with the volume
docker run -v lrs-data:/root/.Lires ...
