[lxc-devel] How to create a container without Internet connection？？

[黄奕]

Hello everybody,
I am using LXC in RedHat 7 and have to  create a redhat container without Internet connection.
I tried to modify the template file of centos(changing the mirrorlist path to "file:///mnt" where i mount my .iso), but I failed and I got errors below:


Host CPE ID from /etc/os-release: cpe:/o:redhat:enterprise_linux:7.0:GA:server
This is not a CentOS or Redhat host and release is missing, defaulting to 6 use -R|--release to specify release
Checking cache download in /usr/local/var/cache/lxc/centos/x86_64/6/rootfs ...
Downloading centos minimal ..
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
 One of the configured repositories failed (Unknown),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

      1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working

        upstream. This is most often useful if you are using a newer

        distribution release than is supported by the repository (and the

        packages for the previous distribution release still work).

      3. Disable the repository, so yum won't use it by default. Yum will then

        just ignore the repository until you permanently enable it again or use

        --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>

     4. Configure the failing repository to be skipped, if it is unavailable.

        Note that yum will try to contact the repo. when it runs most commands,

        so will have to try and fail each time (and thus. yum will be be much

        slower). If it is a very temporary problem though, this is often a nice

        compromise:

 

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

 Cannot find a valid baseurl for repo: base

Failed to download the rootfs, aborting.

Failed to download 'centos base'

failed to install centos

lxc_container: lxccontainer.c: create_run_template: 1125 container creation template for mylxc4 failed
