# N.B. The only tool missing here that is mentioned in the document is `zenmap`
# purely because this image is intended to be run via a CLI and `zenmap` is a GUI
# to `nmap` i.e. one can play around with the tools by running:

# $ docker build --name bite_size_networking:latest .
# $ docker run --rm -d --name bsn_test bite_size_networking:latest
# $ docker exec -it bsn_test bash

# Alternatively, one can change the `ENTRYPOINT` to `["bash"]` and run:

Ansible variable precedence

Source: http://docs.ansible.com/ansible/latest/playbooks_variables.html#variable-precedence-where-should-i-put-a-variable

From least to most important

• command line values (for example, -u my_user, these are not variables)
• role defaults (defined in role/defaults/main.yml)
• inventory file or script group vars
• inventory group_vars/all

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.

12.5 style custom resources

This is by far the most recommended way of writing resources for all users. There are two gotchas which we're working through:

1. For helper functions that you used to write in your provider code or used to mixin to your provider code, you have to use an action_class do ... end block.

Networking Troubles with Vagrant Box ubuntu/wily64

For some reason, the network interfaces in ubuntu/wily64 fail to configure at boot. The interfaces are renamed during boot, with dmesg reporting things like udev renamed network interface eth0 to enp1s0. This is apparently the result of a change in systemd. You can read about it here:

Starting with v197 systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces. This is a departure from the traditional interface naming scheme ("eth0", "eth1", "wlan0", ...), but should fix real problems.
