Give your host access to Docker containers with macvlan

Let's assume you have a macvlan interface running.

#$ docker network inspect test_loc-macvlan

[

Ostico

#!/bin/bash
ps -ylC apache2 --sort:rss | awk '{sum+=$8; ++n} END {print "Tot="sum"("n")";print "Avg="sum"/"n"="sum/n/1024"MB"}'

Ostico

#!/bin/bash

#
# copy this into /etc/profile.d/instance-name-tag.sh
#
# you will need: 
# - curl, jq, and aws cli installed
# - an IAM role that gives the EC2 instance access to describe tags

How to use a custom resolv.conf file with systemd-resolved in Ubuntu

Stages

• Disable and stop the systemd-resolved service:

  sudo systemctl stop systemd-resolved
  

• Then put the following line in the [main] section of your /etc/NetworkManager/NetworkManager.conf:

Ostico

# maximum capability of system
user@ubuntu:~$ cat /proc/sys/fs/file-max
708444

# If this limit is too low, you can increase the available limit to say 200000
user@ubuntu:~$ sudo vim /etc/sysctl.conf

# add the following line to it
fs.file-max = 200000
