The save command perform configuration save for all the containers running in a lab.

The exact command that performs configuration save depends on a given kind. The below table explains the method used for each kind:

containerlab [global-flags] save [local-flags]


topology | name#

With the global --topo | -t flag a user sets the path to the topology definition file that will be used to spin up a lab.

When the topology path refers to a directory, containerlab will look for a file with .clab.yml extension in that directory and use it as a topology definition file.

When the topology file flag is omitted, containerlab will try to find the matching file name by looking at the current working directory.

If more than one file is found for directory-based path or when the flag is omitted entirely, containerlab will fail with an error.


The local --node-filter flag allows users to specify a subset of topology nodes targeted by save command. The value of this flag is a comma-separated list of node names as they appear in the topology.

When a subset of nodes is specified, containerlab will only attempt to save configuration on the selected nodes.
