# Notes: Automating Container Updates
This would have worked in an lxc only world...
```sh
#!/bin/bash
# Purpose: Update all lxc vms
# Note: Tested on Ubuntu LTS only
# Author: Vivek Gite <www.cyberciti.biz>, under GPL v2+
# -------------------------------------------------------
# Get the vm list
vms="$(lxc-ls --active)"
# Update each vm
update_vm(){
local vm="$1"
echo "*** [VM: $vm [$(hostname) @ $(date)] ] ***"
/usr/bin/lxc-attach -n "$vm" apt-get -- -qq update
/usr/bin/lxc-attach -n "$vm" apt-get -- -qq -y upgrade
/usr/bin/lxc-attach -n "$vm" apt-get -- -qq -y clean
/usr/bin/lxc-attach -n "$vm" apt-get -- -qq -y autoclean
# Note for RHEL/CentOS/Fedora Linux comment above two line and uncomment the following line #
# lxc-attach -n "$vm" yum -y update
echo "-----------------------------------------------------------------"
}
# Do it
for v in $vms
do
update_vm "$v"
done
```
This works for updating everything debian under the lxd.. Not sure you need anything else :)
```sh
Shell Fragment for looking at os distribution.
# Determine OS platform
UNAME=$(uname | tr "[:upper:]" "[:lower:]")
# If Linux, try to determine specific distribution
if [ "$UNAME" == "linux" ]; then
# If available, use LSB to identify distribution
if [ -f /etc/lsb-release -o -d /etc/lsb-release.d ]; then
export DISTRO=$(lsb_release -i | cut -d: -f2 | sed s/'^\t'//)
# Otherwise, use release info file
else
export DISTRO=$(ls -d /etc/[A-Za-z]*[_-][rv]e[lr]* | grep -v "lsb" | cut -d'/' -f3 | cut -d'-' -f1 | cut -d'_' -f1)
fi
fi
# For everything else (or if above failed), just use generic identifier
[ "$DISTRO" == "" ] && export DISTRO=$UNAME
unset UNAME
```
