Review context package dependencies

[dann1]

Description
Running hostname contextualization fails on some distros from the LXD marketplace.

Ubuntu Xenial:

root@LXC_NAME:~# hostnamectl set-hostname --static oned
Failed to create bus connection: No such file or directory

Debian Buster:

root@LXCNAME:~# hostnamectl set-hostname --static oned
Could not set property: Failed to activate service 'org.freedesktop.hostname1': timed out (service_start_timeout=25000ms)

To Reproduce
Deploy any of the affected apps from the LXD marketplace.

Expected behavior
Hostname contextualzation should set the appropriate hostname

Details

• Affected Component: Virtualization
• Hypervisor: LXD
• Version: 5.8.0

Additional context
The command Ubuntu bionic runs ok, also 16.04 - KVM image doesn't show issues.

Progress Status

• Branch created
• Code committed to development branch
• Testing - QA
• Documentation
• Release notes - resolved issues, compatibility, known issues
• Code committed to upstream release/hotfix branches
• Documentation committed to upstream release/hotfix branches

I had to install dbus package on Xenial container to get hostname contextualization working.

Thanks a lot for the info!

I would say Ubuntu (and maybe other images) are missing much more services to be usable (e.g., openssh-server).

[dann1]

The container images from the public LXD servers are very minimal, we need to look for the distros we support context on and check for missing dependencies. Alpines don't even have bash

[vholer]

Bash is already a dependency of Alpine packages. Maybe you are installing them wrong.

Anyway, I'm changing the topic of this issue to review all the dependencies. The dbus PR is for now merged.

List of dependencies to consider (to be updated):

• SSH server (note: Alpine has multiple alternatives)

I think we can close this since OpenNebula/one#3189 and https://github.com/OpenNebula/infra/pull/344 showed good results for tests
