dockerd-entrypoint.sh: 148: modprobe: not found

It looks like the Kasm Workspaces container is encountering permission issues and missing the modprobe command. These issues can be resolved by running the container in privileged mode and ensuring the necessary permissions are granted. Here’s how you can address these issues: Step 1: Run the Container in Privileged Mode Running the container in privileged mode will grant it the necessary permissions to perform operations that require elevated privileges.

1. Stop the Existing Container

   # docker stop kasm_workspaces
   # docker rm kasm_workspaces
   

2. Run the Container in Privileged Mode

   # docker run -d --name kasm_workspaces --restart unless-stopped \
     --privileged \
     -p 8444:8443 -p 443:443 -p 80:80 \
     kasmweb/workspaces:1.16.1
   

Step 2: Ensure modprobe is Available The modprobe command is used to add and remove modules from the Linux kernel. Ensure that it is available on your host system.

1. Install modprobe if Missing

   # apt install kmod
   

Step 3: Verify Permissions and AppArmor Ensure that the necessary permissions are granted and AppArmor is not restricting the container.

1. Check AppArmor Status

   # aa-status
   

2. Disable AppArmor for the Container (if necessary)

   # aa-complain /etc/apparmor.d/docker
   

Step 4: Restart the Container After making these changes, restart the container and check the logs again.

1. Restart the Container

   # docker restart kasm_workspaces
   

2. Check the Logs

   # docker logs -f kasm_workspaces
