Dependency Installed:
lua-alt-getopt.noarch 0:0.7.0-1.el6 lua-filesystem.x86_64 0:1.4.2-1.el6 lua-lxc.x86_64 0:1.0.11-1.el6 lxc-libs.x86_64 0:1.0.11-1.el6


Create your first container!

Let's check the available templates first:

ls /usr/share/lxc/templates/
lxc-altlinux lxc-busybox lxc-cirros lxc-download lxc-gentoo lxc-opensuse lxc-plamo lxc-ubuntu
lxc-alpine lxc-archlinux lxc-centos lxc-debian lxc-fedora lxc-openmandriva lxc-oracle lxc-sshd lxc-ubuntu-cloud

We use the lxc-create command, the relevant parts below are as follows:

-n = the name of the container

-t = template type (so if we see lxc-debian) we would type "debian"

-r = release (in Debian there is wheezy, sid, stretch etc..) that correspond to specific versions

-a = architecture (most commonly amd64 for 64bit or i386 for 386)

-p = the path this is optional but if you want it somewhere else like /mnt/sdb1 you would use this flag

lxc-create -n -t debian -- -r stretch -a amd64
/usr/share/lxc/templates/lxc-debian: line 574: type: debootstrap: not found
'debootstrap' command is missing
lxc_container: lxccontainer.c: create_run_template: 1092 container creation template for mywheezy failed
lxc_container: lxc_create.c: main: 274 Error creating container mywheezy
-bash-4.1# lxc-create -n -t debian -- -r stretch -a amd64
/usr/share/lxc/templates/lxc-debian: line 574: type: debootstrap: not found
'debootstrap' command is missing
lxc_container: lxccontainer.c: create_run_template: 1092 container creation template for failed
lxc_container: lxc_create.c: main: 274 Error creating container

Oops, we have a debootstrap missing command error. For Debian machines we need debootstrap:

yum -y install debootstap

Try again:

lxc-create -n -t debian -- -r stretch -a amd64 -p /mnt/sdb1/
debootstrap is /usr/sbin/debootstrap
