lxd-import-ansibleplaybook

This Ansible Playbook looks for LXD image tar files in a directory and imports them to the local image store for public access. Imported image tar files are then moved to a different directory. You can read more about LXD image management and running a public LXD server here.

Instructions

Before running this playbook, the following variables need to be specified in the external_vars.yml file:

  • imagedir: This is the directory the playbook should look for LXD image tar files. The playbook assumes all *.tar.gz files in this directory are LXD images.
  • lxcpath: Path to your lxc installation. You can determine this using which lxc on Ubuntu. This varies based on installation method.
  • oldimagepath: Directory where imported images will be moved to.

After the variables above have been set, run the playbook using:

ansible-playbook main.yml

Notes

Please note the following:

  • This playbook has only been tested on Ubuntu 16.04 & Ubuntu 18.04 with Ansible 2.7 installed using pip install ansible.
  • Currently, errors in the LXD image import step are ignored. This is due to the random behavior of this task. Errors were being returned even when images were successfully imported. This needs further investigation.
  • It is assumed that tar image files will be be copied to imagedir using something like rsync which creates a temporary file in a different location before moving the completed file to the destination directory. The playbook does not check to see if a tar file is still being written to before performing the image import.
