ISSUE TYPE

Bug Report

COMPONENT NAME

lxc_container

ANSIBLE VERSION

ansible 2.1.0.0
  config file =
  configured module search path = Default w/o overrides

CONFIGURATION

None

OS / ENVIRONMENT

I have used both Ubuntu 14.04 LTS and Ubuntu 16.04 LTS with the same results. More details in this gist: https://gist.github.com/odyssey4me/97e0edbb9e46748cdf8775b786f820b6

SUMMARY

When using the lxc_container module to create a container (overlayfs1) based on a snapshot of another container (base1) (ie lxc-clone --snapshot), instead of starting 'overlayfs1' the base container starts and thus the one that's supposed to start fails.

STEPS TO REPRODUCE

Using https://gist.github.com/odyssey4me/97e0edbb9e46748cdf8775b786f820b6#file-0-create-containers-yml you will notice the changes in state. Instead of overlayfs1 and overlayfs2 being in a started state (with base1 and base2 in a stopped state), the result is the opposite.

The playbook below does a comparative test using the module and the CLI.

- name: Create containers via host target
  hosts: localhost
  tasks:

    - name: Clean up previous tests
      lxc_container:
        name: "{{ item }}"
        state: absent
      with_items:
        - overlayfs1
        - base1
        - overlayfs2
        - base2

    - name: Create container base1
      lxc_container:
        name: base1
        template: download
        state: stopped
        backing_store: dir
        template_options: --dist ubuntu --release trusty --arch amd64

    - name: Check state of base1
      command: lxc-info -n base1

    - name: Create container overlay1
      lxc_container:
        name: base1
        clone_snapshot: yes
        clone_name: overlayfs1
        state: started
        backing_store: overlayfs

    - name: Check state of base1
      command: lxc-info -n base1

    - name: Check state of overlayfs1
      command: lxc-info -n overlayfs1

    - name: Create container base2
      command: lxc-create --name=base2 --template=download -- --dist ubuntu --release trusty --arch amd64

    - name: Check state of base2
      command: lxc-info -n base2

    - name: Create container overlayfs2
      command: lxc-clone --snapshot --backingstore overlayfs --orig base2 --new overlayfs2

    - name: Start container overlayfs2
      command: lxc-start --name overlayfs2

    - name: Check state of base2
      command: lxc-info -n base2

    - name: Check state of overlayfs2
      command: lxc-info -n overlayfs2

EXPECTED RESULTS

The container overlayfs1 and overlayfs2 should be running, while the base containers should be stopped.

ACTUAL RESULTS

The container base1 and overlayfs2 are running. The container overlayfs1 tried to start, but failed because the base was running.

It seems that option state is bound to container specified by name. Additionally, state is by default started. The possible workaround would be to explicitly force stop state on base container during clone step, and later start cloned container in another task:

- name: Create container overlay1
  lxc_container:
    name: base1
    clone_snapshot: yes
    clone_name: overlayfs1
    state: stopped
    backing_store: overlayfs
    
- name: Start container overlay1
  lxc_container:
    name: overlayfs1
    state: started

odyssey4me · 2016-09-14T22:20:40Z

@morfeush22 Yeah, that makes sense as a workaround. Thanks - we're doing something similar, but due to #2691 we're using the CLI commands anyway.
