GitHub user Fr3dL closed a discussion: Issue generating SystemVM SSH keys when
running cloudstack-management in a Docker container
Hello all,
I am trying to run cloudstack-management from a Docker container (ACS 4.18.1
using Ubuntu 22.04 image). Most of it is working as expected, however I cannot
start the SystemVMs. I am getting this in the logs of the ACS node:
Failed to scp files to system VM due to, /root/.ssh/id_rsa.cloud (No such file
or directory)
I understand that there is a script that can stop the management service to
copy the SSH keys if running from a container with no privileges
(/usr/share/cloudstack-common/scripts/vm/systemvm/injectkeys.sh):
```
# if running into Docker as unprivileges, skip ssh verification as iso cannot
be mounted due to missing loop device.
if [ -f /.dockerenv ]; then
if [ -e /dev/loop0 ]; then
# it's a docker instance with privileges.
copy_priv_key $newprivkey
else
......
```
I would really appreciate if someone had the time to explain the process when
deploying a SystemVM in 4.18.1? When and how does it mount the SystemVM on the
management server (is it always using /dev/loop0)?
I am also not sure at what point this script is running (like most of the
scripts in the /usr/share/cloudstack-common/scripts/vm directory ). Is it every
time we deploy a SystemVM, or only when we download the ISO to the secondary
storage for the first time?
Any help will be much appreciated.
