System Services

A system service is a container that can be run in either System Docker or Docker. Rancher provides services that are already available in RancherOS by adding them to the os-services repo. Anything in the index.yml file from the repository for the tagged release will be an available system service when using the ros service list command.

Enabling and Starting System Services

For any services that are listed from the ros service list, they can be enabled by running a single command. After enabling a service, you will need to run start the service.

# List out available system services
$ sudo ros service list
disabled amazon-ecs-agent
disabled kernel-headers
disabled kernel-headers-system-docker
disabled open-vm-tools
# Enable a system service
$ sudo ros service enable kernel-headers
# Start a system service
$ sudo ros service up kernel-headers

Disabling and Removing System Services

In order to stop a system service from running, you will need to stop and disable the system service.

# List out available system services
$ sudo ros service list
disabled amazon-ecs-agent
enabled kernel-headers
disabled kernel-headers-system-docker
disabled open-vm-tools
# Disable a system service
$ sudo ros service disable kernel-headers
# Stop a system service
$ sudo ros service stop kernel-headers
# Remove the containers associated with the system service
$ sudo ros service down kernel-headers

If you want to remove a system service from the list of service, just delete the service.

$ sudo ros service delete <serviceName>
