lxc-helpers - LXC container management helpers
|
|
|
|
SYNOPSIS
|
|
|
|
lxc-helpers [-v|--verbose] [-h|--help]
|
|
[-o|--os {bookworm|bullseye} (default bookworm)]
|
|
command [arguments]
|
|
|
|
DESCRIPTION
|
|
|
|
A thin shell based layer on top of LXC to create, populate, run and
|
|
destroy LXC containers. A container is created from a copy of an
|
|
existing container.
|
|
|
|
CREATE AND DESTROY
|
|
|
|
lxc_prepare_environment
|
|
|
|
Install LXC dependencies.
|
|
|
|
lxc_template_release
|
|
|
|
Echo the name of the container for the Operating System
|
|
specified with `--os`.
|
|
|
|
lxc_build_template `existing_container` `new_container`
|
|
|
|
Copy `existing_container` into `new_container`. If
|
|
`existing_container` is equal to $(lxc_template_release) it
|
|
will be created on demand.
|
|
|
|
lxc_container_mount `name` `path`
|
|
|
|
Configure `name` container to bind mount `path` so that it is
|
|
also accessible at `path` from within the container.
|
|
|
|
lxc_container_start `name`
|
|
|
|
Start the `name` container.
|
|
|
|
lxc_container_stop `name`
|
|
|
|
Unmount all bind mounted directories and stop the `name`
|
|
container.
|
|
|
|
lxc_container_destroy `name`
|
|
|
|
Call lxc_container_stop `name` and destroy the container.
|
|
|
|
ACTIONS IN THE CONTAINER
|
|
|
|
For some command lxc_something `name` that can be called from outside the container
|
|
there is an equivalent function lxc_something_inside that can be called from inside
|
|
the container.
|
|
|
|
lxc_install_lxc `name` `prefix`
|
|
lxc_install_lxc_inside `prefix`
|
|
|
|
Install LXC in the `name` container to allow the creation of
|
|
named containers. `prefix` is a class C IP prefix from which
|
|
containers will obtain their IP (for instance 10.40.50).
|
|
|
|
lxc_container_run_script `name` `path`
|
|
lxc_container_run_script_as `name` `user` `path`
|
|
|
|
Run the script found at `path` within the `name` container. The
|
|
environment is cleared before running the script. The first form
|
|
will run as root, the second form will impersonate `user`.
|
|
|
|
lxc_container_user_install `name` `user_id` `user` [`homedir` default `/home`]
|
|
|
|
Create the `user` with `user_id` in the `name` container with a
|
|
HOME at `/homedir/user`. Passwordless sudo permissions are
|
|
granted to `user`. It is made a member of the groups docker, kvm
|
|
and libvirt if they exist already. A SSH key is created.
|
|
|
|
Example: lxc_container_user_install mycontainer $(id -u) $(USER)
