I confirm this is working no trouble..

Note:
If you have container dual stack (IPV4,IPV6)
but NOT all container on the IPV4 subnet,
you need to define a second bridge on
the host (with the IPV6 number) and container
with a second interface (eth1) attached to
the host second bridge.

Having the container set with one interface
carrying both IPV6+IPV6, but not all the container
on the same IPV4 subnet make the routing quite
unreliable.

Hello,

Question
I have a big node running several containers
Below the memory usages
What is important for performance
The Physical memory usage (88%)
Or the kernel+ applications (28%)
Has someone a explanation how to read this ?

Memory Usage
Type Percent Capacity Free Used Size
Physical Memory 88% 2.74 GB 20.96 GB 23.71 GB
- Kernel + applications 28% 6.64 GB
- Buffers 3% 837.63 MB
- Cached 57% 13.51 GB
Disk Swap 0% 3.99 GB 8.21 MB 4.00 GB


Thanxs

Steffan

A few hints to consider:
Linux always try to use the whole RAM available, free RAM is useless
after all. So nearly all RAM not used by applications/kernel/network
buffers is used as filesystem cache as needed. In your case the most
is in the fs-cache and Swap is not used at all, so you don't have a
RAM shortage/performance problem related to RAM.

Regards

Andreas
