Got following error when starting VM
No 3D Support is available from the Host - The 3D features of the virtual machine will be disabledAdd following lines in .vmx file
mks.enableMTLRenderer = "0"
mks.enableGLRenderer = "1"Use environment variable RSYNC_PASSWORD to provide password to rsync command
export RSYNC_PASSWORD=$PASSWORD
rsync -zvr source destinationor
env RSYNC_PASSWORD=$PASSWORD rsync -zvr source destinationrsync --password-file=rsync_pass -zvr source destinationSuch as sshpass and public key.
How can I rsync without prompt for password, without using public key authentication?
Docker requires legacy iptables. If docker installation got network issue, following commands might fix the issue.
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
apt remove apparmorUse docker pull command can get image digest
docker pull registry.example.com/image_path/image:tagIf it is daily build for container backup purpose, the tag can be in date format, such as YYYYMMDD. The output can be
20210624: Pulling from image_path/image
