   4 What is lxc:
   5
   6   The container technology is actively being pushed into the mainstream linux
   7   kernel. It provides the resource management through the control groups  aka
   8   process containers and resource isolation through the namespaces.
   9
  10   The  linux  containers, lxc, aims to use these new functionalities to pro-
  11   vide an userspace container object which provides full  resource  isolation
  12   and resource control for an applications or a system.
  13
  14   The first objective of this project is to make the life easier for the ker-
  15   nel developers involved in the containers project and  especially  to  con-
  16   tinue  working  on  the  Checkpoint/Restart  new features. The lxc is small
  17   enough to easily manage a container with simple command lines and  complete
  18   enough to be used for other purposes.
  19
  20 Using lxc:
  21
  22   Refer the lxc* man pages (generated from doc/* files)
  23
  24 Downloading the current source code:
  25
  26   Source for the latest released version can always be downloaded from
  27   http://lxc.sourceforge.net/download/lxc
  28
  29   You can browse the up to the minute source code and change history online.
  30   http://lxc.git.sourceforge.net
  31
  32   For an even more bleeding edge experience, you may want to look at the
  33   staging branch where all changes aimed at the next release land before
  34   getting pulled into the master branch.
  35   http://github.com/lxc/lxc
  36
  37   For detailed build instruction refer to INSTALL and man lxc man page
  38   but a short command line should work:
  39   ./autogen.sh && ./configure && make && sudo make install && sudo lxc-setcap
  40   preceded by ./autogen.sh if configure do not exist yet.
  41
  42 Getting help:
  43
  44   when you find you need help, you can check out one of the two
  45   lxc mailing list archives and register if interested:
  46   https://lists.sourceforge.net/lists/listinfo/lxc-devel
  47   https://lists.sourceforge.net/lists/listinfo/lxc-users
  48
  49 Portability:
  50
  51   lxc  is  still  in  development, so the command syntax and the API can
  52   change. The version 1.0.0 will be the frozen version.
  53
  54   lxc is developed and tested on Linux since kernel mainline version 2.6.27
  55   (without network) and 2.6.29 with network isolation.
  56   It's compiled with gcc, and should work on most architectures as long as the
  57   required kernel features are available. This includes (but isn't limited to):
  58   i686, x86_64, ppc, ppc64, S390, armel and armhf.

  63 Seccomp with LXC
  64 ----------------
  65
  66 To restrict a container with seccomp, you must specify a profile which is
  67 basically a whitelist of system calls it may execute.  In the container
  68 config file, add a line like
  69
  70 lxc.seccomp = /var/lib/lxc/q1/seccomp.full
  71
  72 I created a usable (but basically worthless) seccomp.full file using
  73
  74 cat > seccomp.full << EOF
  75 1
  76 whitelist
  77 EOF
  78 for i in `seq 0 300`; do
  79     echo $i >> secomp.full
  80 done
  81 for i in `seq 1024 1079`; do
  82     echo $i >> seccomp.full
  83 done
