Using Docker – Operations with Containers

You can do the following with containers:

• Restart (Restart) or stop (Stop) a container. In these cases,
  the container will be recreated with the current settings.

  Note: If you did not save the data to the mounted volumes (see the
  Volume Mapping section below), the data will be lost.

• View logs and resource consumption (Details).

• Change container settings, such as environment variables or volume
  mapping (Settings or Details > Settings).

  In Plesk on CentOS, you can set a memory limit for a container
  (Settings > Memory limit).

• Rename a container (Settings > Container name).

• Recreate a container using the same or another version of the image
  (Details > Recreate).

• Create an image based on a container with your custom settings
  (Details > Save as Image).

• Take a snapshot of a container (Details > Download a
  Snapshot).

• Remove a container (Remove or Details > Remove).

Recreating a Container

Usually, you need to recreate a container when you want to update the
application to a newer version. In fact, you can rebuild a container
using any application version available in the catalog, not only a newer
one.

Custom settings are preserved during recreation. To preserve data used
by the application inside a container, you should specify volume mapping
before you recreate a container. Volume mapping enables you to have
access to directories used inside a container (see Volume
Mapping in container settings).

To recreate a container:

1. Go to Docker and click Details below the container you want
   to recreate.
2. Click Recreate in the container settings and specify the image
   version, and whether to use default environment variables.
