A LXD UI for managing containers across hosts

neophenix Ping checks to verify IP is available and container is up (#8)
* go-ping dep

* check the IP we pick from DNS with a ping (optional) before using it

* flag off the ping test

* Ping non-DHCP containers before bootstrapping

Since we will have an IP to look for if we used a DNS provider,
instead of just sleeping and hoping the cotainer comes up, we will
ping it.

If we don't get a response and time out then we assume its bad and
bail on bootstrapping.

Also only use networking templates for non-DHCP containers as the
default configs in the images should just work for DHCP (to be
revisited later)

LXDepot is a simple UI to interface with one to many LXD servers, allowing you to start, stop, create, and delete containers.

Additionally, it can talk to third party DNS providers to automatically register and remove records, and bootstrap containers so once a user hits create, they can sit back for a moment and then be ready to SSH in and begin work.


LXDepot has only a few command line flags to keep things simple

    -port       (default:8080) which port to bind to
    -config     (default:configs/config.yaml) instance config file
    -webroot    (default:web/) where our templates + static files live
    -cache_templates (default:true) more for dev work, setting to false make the service read the web templates off disk each request


./lxdepot -port=8888 -config=/opt/lxdepot/configs/config.yaml -webroot=/opt/lxdepot/web/


The config file controls PKI, the hosts we talk to, DNS configuration, and bootstrapping commands. A fully documented sample config can be found in configs/sample.yaml


To use this you need to create a client cert and key using openssl or similar. An example openssl command is:

openssl req -x509 -nodes -newkey rsa:4096 -keyout client.key -out client.crt -days 365 -subj '/CN=lxdepot'

This cert will then need added to all the LXD hosts you want to talk to. Put the client.crt on the host and then do:

lxc config trust add client.crt

Alter the commands as you see fit, these are only examples.

The server certificate can then be found (on the LXD host) at: /var/lib/lxd/server.crt

Disabling remote management for certain containers

Sometimes you don't want people messing with your stuff. To that end, if you do not want LXDepot to manage a container, that is to say start, stop, delete (it will still be listed and you can view info on it), add this user flag to the container. It will tell LXDepot the container is off limits

During creation add this to the config, the container will start and bootstrap and then be unmanageable by LXDepot


Or from the command line:

lxc config set CONTAINERNAME user.lxdepot_lock true


First, this was an experiment in learning Go, so I'm sure there are a few things that make you go ... wat

Secondly, everthing was initially developed for use at Circonus so perhaps some assumptions were made (like limiting to IPv4).

Last, tests are light / not really exsistent for anything as this depends on a lot of external services to really do anything, and I haven't decided how to handle that in test yet
