lxd-functions

This bash file allows you to create, start and delete an LXD container. The goal is to mount the container with appropriate rights and ownership (with bindfs). After container started, you can work directly on the host machine, the current user is used in the mounted point and you have full access to it. In the container, a default user is used to map with the host user.

Dependencies

• bindfs : the bash package to make advanced mounted directory (in ubuntu sudo apt-get install bindfs)

Installation

Clone this repository in /path/to/lxd-functions

Add in the .bashrc file (/home/<me>/.bashrc) or in the .profile :

if [ -f /path/to/lxd-functions/main.sh ]; then
  . /path/to/lxd-functions/main.sh
fi

Copy the example of configration file /path/to/lxd-functions/config.sh.example to /path/to/lxd-functions/config.sh and edit it, specially check that :

• LXD_SOURCE_DIR need to match with the path of LXD containers in your system
• LXD_MOUNT_DIR, it's where containers will be mounted. The default value is /var/lxd. It will be automaticaly created if you run the script.

To allow bash-completion to work, you need to give read access of the /var/lib/lxd/containers like this : sudo chmod ugo+r /var/lib/lxd/containers/

No need to change an existing LXD container, this script use the LXD API without container modification !

Commands

Commands available:

• lxd-start <container name> (Start an LXD container and mount it)
• lxd-stop <container name> (Stop an LXD container and umount it)
• lxd-bindfs-mount <container name> <host user> <host group> <guest user> <guest group> (Mount an LXD Container)
• lxd-bindfs-umount <container name> (Umount an LXD Container)
• More soon (for example lxd-create ...)

Example of use

In this example, you already have a LXD named mylxd (started or not, it doesn't matter) and you let the default configuration (in the config.sh). Before working with it, just enter this : lxd-start mylxd The script will start LXD container (with lxc start mylxd), then try to mount the container in this path : /var/lxd/mylxd, if the directory mylxd isn't already present, the script will ask if you agree to create it automatically. That's all ! You can try to create files directly in the container or in the mounted directory, the file created will have the current user uid/gid in the host and the default user in the container.

The command lxd-stop mylxd is not required, but it will shutdown the lxd and unmount it for you.

Others commands are not needed too, this is for advanced use.
