Is it possible to get all MAC/IPs for macvlan interface?
I have macvlan interface:

[root@srv ~]# ip a

    ..................

    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000

        link/ether 52:54:00:e7:e6:10 brd ff:ff:ff:ff:ff:ff

    ......................

    4: macvlan0@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN qlen 1

        link/ether 52:54:00:e7:e6:11 brd ff:ff:ff:ff:ff:ff

        inet 1.1.0.6/24 brd 1.1.0.255 scope global macvlan0

           valid_lft forever preferred_lft forever

and i have 16 docker containers with macvlan interfaces

[root@srv ~]# docker ps | grep 'Up ' |wc

     16     166    3512

how can i list ALL subinterfaces for macvlan0 ?

ip netns - show nothing

lsns -t net - show 16 docker's net namespaces

arp -an shows <16 arps, and some arps from other hosts (1.1.0.1,1.1.0.253,1.1.0.254)

[root@srv ~]# arp -an

? (1.1.0.1) at 00:00:0c:07:ac:1e [ether] on macvlan0

? (1.1.10.1) at 52:54:00:0e:84:51 [ether] on eth1

[root@srv ~]#

I understand, that all macvlan0 interfaces are in different net namespaces, and apparently ip link show macvlan0 show can't show subinterfaces in different namespaces.
But is there other command to get all ip's and MAC's in all namespaces ?

You need to iterate over each namespace, and run ip in this namespace, e.g. ip -n your_namespace addr show. Not fun. What's wrong with docker network inspect docker-net instead?

I wonder why it is impossible to see all of MACs of particular macvlan interface. And ip -n don't work, due empty of /var/run/netns And i can have some macvlan subinterfaces inside docker, some not. So docker network inspect not best choice. I want to have most general way to list all the MACs of particular macvlan in all namespaces (in docker or not)

Because I'd assume it's not a "particular macvlan inerface", it's a dozen interfaces in different namespaces which all happen to have the name macvlan0. So you need to iterate over all of those, one way or other. I haven't tried to access docker namespaces before, you may need the docker tools to run ip in that particular namespace.

I wonder why it is impossible to see all of MACs of particular macvlan interface. And ip -n don't work, due empty of /var/run/netns And i can have some macvlan subinterfaces inside docker, some not.
