# More Notes and Tips for Using LXD
|
||
|
|
|
||
|
|
### LXD Server and _Clients_
|
||
|
|
|
||
|
|
#####Your LXD hosts can establish a secure client-server relationship very quickly and easily.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# First enable networking on Both the server and client:
|
||
|
|
lxc config set core.https_address [::]:8443
|
||
|
|
|
||
|
|
# Then on the server, set a password:
|
||
|
|
lxc config set core.trust_password <something-secure>
|
||
|
|
|
||
|
|
# Then on the client, add the server as a remote,
|
||
|
|
# and enter the password you just created for it:
|
||
|
|
lxc remote add <server> <ip address>
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
#####Now from the perspective of the client machine, the server is just another remote, same as:
|
||
|
|
|
||
|
|
* **local** (the default)
|
||
|
|
* **ubuntu** (where ubuntu images come from), and
|
||
|
|
* **images** (where lxc images of other distros come from).
|
||
|
|
* **clyde** (your host named clyde)
|
||
|
|
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# command to list remotes
|
||
|
|
# returns local, images, ubuntu, etc.
|
||
|
|
lxc remote list
|
||
|
|
|
||
|
|
# command to list containers on a remote
|
||
|
|
lxc list <remote>:
|
||
|
|
# i.e. for a remote named "black"
|
||
|
|
lxc list black:
|
||
|
|
|
||
|
|
# command to list images on a remote
|
||
|
|
# i.e. for a remote name "images"
|
||
|
|
lxc image list images:
|
||
|
|
# or for a remote named "ubuntu"
|
||
|
|
lxc image list ubuntu:
|
||
|
|
# or for a specific image
|
||
|
|
lxc image list ubuntu:16.04 # or
|
||
|
|
lxc image list ubuntu:fdceb4d263b9
|
||
|
|
```
|
||
|
|
|
||
|
|
#####Now you can move containers around between servers and clients.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# launch an ubuntu container from the ubuntu remote
|
||
|
|
lxc launch ubuntu:16.04 <optional name>
|
||
|
|
# or from a remote named "black"
|
||
|
|
lxc launch black:069b95ed3a60 <optional name>
|
||
|
|
# to list the images that black has available
|
||
|
|
lxc image list black:
|
||
|
|
|
||
|
|
# copy a container from a server named "black"
|
||
|
|
# to your local client
|
||
|
|
lxc copy black:jerry <optional name to copy to>
|
||
|
|
# or from "local" back to "black"
|
||
|
|
lxc copy jerry black:<optional name to copy to>
|
||
|
|
# or move
|
||
|
|
lxc move black:jerry <optional name to copy to>
|
||
|
|
|
||
|
|
# or change the default remote from "local" to "black"
|
||
|
|
lxc remote set-default black
|
||
|
|
# and then reverse the syntax
|
||
|
|
# copy a container from a server named "black"
|
||
|
|
# to your local client
|
||
|
|
lxc copy jerry local:<optional name to copy to>
|
||
|
|
# or from "local" back to "black"
|
||
|
|
lxc copy local:jerry <optional name to copy to>
|
||
|
|
```
|
||
|
|
|
||
|
|
#####Or remote control another LXD server
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# bash shell on container named "jim" running on
|
||
|
|
# a remote server named "black"
|
||
|
|
lxc exec black:jim bash
|
||
|
|
|
||
|
|
# copy that
|
||
|
|
lxc copy black:jim black:francine
|
||
|
|
|
||
|
|
# snapshot
|
||
|
|
lxc snapshot black:jim
|
||
|
|
|
||
|
|
# delete a snapshot from a remote container
|
||
|
|
# first get the containers info to see what
|
||
|
|
# snapshots it has
|
||
|
|
lxc info black:jim
|
||
|
|
# and then delete
|
||
|
|
lxc delete black:jim/snap0
|
||
|
|
|
||
|
|
# or rollback/restore,
|
||
|
|
# slightly different syntax vs "delete"
|
||
|
|
lxc restore black:jim snap0
|
||
|
|
```
|
