  • Never: Do not automatically restart the container when it exits. This is the default.
  • Always: Always restart the container regardless of the exit status. When you specify always, Docker will try to restart the container indefinitely. The container will also always start on Docker startup, regardless of the current state of the container.
  • On failure: Restart only if the container exits with a non-zero exit status.
  • Unless stopped: Always restart the container regardless of the exit status, including on Docker startup, except if the container was put into a stopped state before Docker was stopped.

Runtime & Resources

This section lets you configure runtime options for your container, add or configure GPUs for use within the container, and specify resource limitations on the container.

Runtime

Here you can configure runtime options for the container.
Field/Option

Privileged mode
Enable this option to run the container in privileged mode.
Init
Enable this option to tell Docker that an init process should be used as PID 1 in the container.
Runtime
Select the runtime to use to start the container. Options will depend on available runtimes on your Docker host.
Devices
Use this option to make devices on your Docker host available within the container. Click add device to add a new device, and define the host path for the device and the container path for where you want the device to appear within the container.
Sysctls
Use this option to specify sysctls to make available within the container. Click add sysctl to add a new sysctl, and set the name and value for your sysctl as required.
