Facing error while deploying xrd routers using containerlab

[rahulsharma02jul]

Hi Experts,
I am trying to deploy xrd routers using containerlab with this small .yaml file

name: sr

topology:
  nodes:

    xrd1:
      kind: cisco_xrd
      image: xrd-control-plane:24.4.1
      startup-config: xrd1.cfg
      cmd: /bin/bash

    xrd2:
      kind: cisco_xrd
      image: xrd-control-plane:24.4.1
      startup-config: xrd2.cfg
      cmd: /bin/bash

  links:
    - endpoints: ["xrd1:Gi0-0-0-0", "xrd2:Gi0-0-0-0"]

When i try to deploy using sudo clab deploy -c... it creates the containers but immediately powers them off and shows below error:

ERRO[0002] failed deploy stage for node "xrd1": Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown 
ERRO[0002] failed deploy stage for node "xrd2": Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown

If i remove the cmd statements, it shows below error:

ERRO[0000] failed deploy stage for node "xrd2": Error response from daemon: no command specified 
ERRO[0000] failed deploy stage for node "xrd1": Error response from daemon: no command specified

Please suggest, Thanks in advance

I never used cisco_xrd, but

you’ll need to remove the "cmd: /bin/bash" lines or replace them with a command that actually exists in the xrd-control-plane image—unfortunately, /bin/bash isn’t there. If removing the cmd lines leads to a “no command specified” error, try specifying an actual startup command or just rely on the container’s default entrypoint.

The examples also using the default entrypoint
https://containerlab.dev/manual/kinds/xrd/

I changed the cmd as below (referred from container's default entrypoint)
cmd: /usr/sbin/init
However, container immediately exited after creation. How shall i troubleshoot that

❯ sudo docker logs 42f888e0d45a
assertion failed [!result.is_error]: Failed to create temporary file
(ThreadContextFcntl.cpp:84 create_tempfile)
 [ERROR  ] Unable to determine system memory limit
[ERROR  ] XRd hit a critical error during initialization and has aborted launch

1. you have to remove the cmd
2. you have to use docker load -i <xrd tar archive>
