Frederick Ollinger's questions

Given a Bash Shell say in a Docker container running on Gitlab, for example, how would I get the password to get passed in?

When I login with this:

 $ vault login -method=ldap username=myusername

It asks me for a password.

How do I get the prompt to not stop and for the password to be passed in as a variable?

I plan on using Gitlab Variables to pass in my password.

Given this block of pseudo code from Terraform:

resource "null_resource" {
    provisioner "local-exec" {
        command = "echo hello"
        interpreter = local.os == "Windows" ? ["PowerShell", "-Command"] : ["bash"]
}

How would I get this to run in Powershell on Windows and bash on Linux?

I'd like to start the busybox udhcpd service using systemd.

I have a simple /etc/udhcpd.conf file:

start           192.168.8.20    #default: 192.168.0.20
end             192.168.8.254   #default: 192.168.0.254
interface       wlan0

Here's my /lib/systemd/system/udhcpd.service

[Unit]
Description=DHCP Service

[Service]
ExecStart=/usr/sbin/udhcpd /etc/countx-udhcpd.conf
ExecStartPre=/usr/bin/ip-up.sh

[Install]
WantedBy=multi-user.target

Here's my /usr/bin/ip-up.sh

#!/bin/sh

ip addr add 192.168.8.1 dev wlan0
ip link set wlan0 up

When I run the scripts manually, everything works properly.

But when I run the scripts with systemd, it fails.

systemctl start udhcpd

This is what works:

/usr/bin/udhcpd-ip-up.sh
/usr/sbin/udhcpd /etc/countx-udhcpd.conf

Anyone get this working with systemd?
