[lxc-users] Feature request: raw lxc utilities output format and operations with multiplie containers?

[Andriy Tovstik]

Hi all!

During LXD learning i encountered with lack of some features.

The first one is "raw" output format of lxc list. Currently lxc list
supports two formats: table and json. Unfortunately both formats are
unusable for scripting.
It is very difficult to pass to script output likes:
# lxc list --format table -c n
+------------+
|    NAME    |
+------------+
| mysql-rep1 |
+------------+
| mysql-rep2 |
+------------+
| mysql-rep3 |
+------------+

When i try to use json format i see that useful fields like container name
are missing in output. May be it will be useful to implement feature like:

# lxc list --format raw -c n --no-header
mysql-rep1
mysql-rep2
mysql-rep3

The second feature looks useful is ability run commands on multiplie
containers simultaneously. For example:

# lxc exec web-node* -- apt update

What do you think about it?
