After resizing the disk, root partition did not take more space that is available.
When running
fdisk -l
on remote VM result is :
The backup GPT table is not on the end of the device. This problem will be corrected by write.

I saw lot of answers saying that I should use growpart command, but this command is not available and it seems that in containerOS you cannot install anything. I tried anyway yum, apt, apt-get, rpm without success.
I digged in Google Documentation, but did not find anything related with ContainerOS
The only workaround I found is to restart the VM, but is there any alternative that does not involve a restart ?

I believe you are doing an online resizing of the disk, right? If so, you can reboot your Container-Optimized OS (COS) machine after the resize. After reboot, the filesystem will be automatically resized to fix your disk. What's happening behind the scene, is that everytime COS boot up, resize-stateful-partition.service will handle this logic for you.
If you cannot easily reboot the COS VM, you could try run sudo /usr/share/cloud/resize-stateful, which should also work.
