# LXC Builder
|
|
||||||
|
|
||||||
Type: `lxc`
|
|
||||||
Artifact BuilderId: `ustream.lxc`
|
|
||||||
|
|
||||||
The `lxc` Packer builder builds containers for lxc1. The builder starts an LXC
|
|
||||||
container, runs provisioners within this container, then exports the container
|
|
||||||
as a tar.gz of the root file system.
|
|
||||||
|
|
||||||
The LXC builder requires a modern linux kernel and the `lxc` or `lxc1` package.
|
|
||||||
This builder does not work with LXD.
|
|
||||||
|
|
||||||
~> Note: to build Centos images on a Debian family host, you will need the
|
|
||||||
`yum` package installed. <br />Some provisioners such as `ansible-local` get
|
|
||||||
confused when running in a container of a different family. E.G. it will
|
|
||||||
attempt to use `apt-get` to install packages, when running in a Centos
|
|
||||||
container if the parent OS is Debian based.
|
|
||||||
|
|
||||||
## Basic Example
|
|
||||||
|
|
||||||

}
|
|
||||||
```
|
|
||||||
|
|
||||||
## Configuration Reference
|
|
||||||
|
|
||||||
### Required:
|
|
||||||
|
|
||||||
- `config_file` (string) - The path to the lxc configuration file.
|
|
||||||
|
|
||||||
- `template_name` (string) - The LXC template name to use.
|
|
||||||
|
|
||||||
- `template_environment_vars` (array of strings) - Environmental variables to
|
|
||||||
use to build the template with.
|
|
||||||
|
|
||||||
### Optional:
|
|
||||||
|
|
||||||
- `target_runlevel` (number) - The minimum run level to wait for the
|
|
||||||
container to reach. Note some distributions (Ubuntu) simulate run levels
|
|
||||||
and may report 5 rather than 3.
|
|
||||||
|
|
||||||
- `output_directory` (string) - The directory in which to save the exported
|
|
||||||
tar.gz. Defaults to `output-<BuildName>` in the current directory.
|
|
||||||
|
|
||||||
- `container_name` (string) - The name of the LXC container. Usually stored
|
|
||||||
in `/var/lib/lxc/containers/<container_name>`. Defaults to
|
|
||||||
`packer-<BuildName>`.
|
|
||||||
|
|
||||||
- `command_wrapper` (string) - Allows you to specify a wrapper command, such
|
|
||||||
as `ssh` so you can execute Packer builds on a remote host. Defaults to
|
|
||||||
Empty.
|
|
||||||
|
|
||||||
- `init_timeout` (string) - The timeout in seconds to wait for the the
|
|
||||||
container to start. Defaults to 20 seconds.
|
|
||||||
|
|
||||||
- `template_parameters` (array of strings) - Options to pass to the given
|
|
||||||
`lxc-template` command, usually located in
|
|
||||||
`/usr/share/lxc/templates/lxc-<template_name>`. Note: This gets passed as
|
|
||||||
ARGV to the template command. Ensure you have an array of strings, as a
|
|
||||||
single string with spaces probably won't work. Defaults to `[]`.
|
|
||||||
|
|
||||||
- `create_options` (array of strings) - Options to pass to `lxc-create`. For
|
|
||||||
instance, you can specify a custom LXC container configuration file with
|
|
||||||
`["-f", "/path/to/lxc.conf"]`. Defaults to `[]`. See `man 1 lxc-create` for
|
|
||||||
available options.
|
|
||||||
|
|
||||||
- `start_options` (array of strings) - Options to pass to `lxc-start`. For
|
|
||||||
instance, you can override parameters from the LXC container configuration
|
|
||||||
file via `["--define", "KEY=VALUE"]`. Defaults to `[]`. See
|
|
||||||
`man 1 lxc-start` for available options.
|
|
||||||
|
|
||||||
- `attach_options` (array of strings) - Options to pass to `lxc-attach`. For
|
|
||||||
instance, you can prevent the container from inheriting the host machine's
|
|
||||||
environment by specifying `["--clear-env"]`. Defaults to `[]`. See
|
|
||||||
`man 1 lxc-attach` for available options.

## Configuration Reference
|

### Required:
|
|

|

- `image` (string) - The source image to use when creating the build

container. This can be a (local or remote) image (name or fingerprint).
