Install Prerequisites on ALL (Worker and Master) Nodes

Let's remove any old versions of Docker if they exist:

                  docker-common \
                  docker-selinux \

Running NGINX and CertBot Containers on the Same Host

Running NGINX and CertBot Containers on the Same Host

The Problem

A lot of people run into the problem of running Let's Encrypt's CertBot Tool and an NGINX on the same container host. A big part of this has to do with CertBot needing either port 80 or 443 open for the tool to work as intended. This tends to conflict with NGINX as most people usually use port 80 (HTTP) or 443 (HTTPS) for their reverse proxy. Section 1 outlines how to configure NGINX to get this to work, and Section 2 is the Docker command to run CertBot.

1. NGINX Configuration

I use Docker Compose (docker-compose) for my NGINX server. My docker-compose.yml file looks something like this:

Installing Fedora 23 on Macbook Pro Retina 2016, and attaching Airport Extreme

Installing Fedora on Macbook Pro retina

  1. Download Fedora 23 iso, create a usb bootable media Follow instructions here Basically,
  2. use diskutil list to figure out which drive is the usb, on macbook pro with 1 hardrive, the usb is /dev/disk2
  3. umount the disk using diskutil unmountDisk /dev/disk2 or use Mac's Disk Utility (just umount, don't eject, umount removes it from directory structure and eject disconncet it altogether)
  4. use dd(a low level cp) to write iso content into the usb drive, sudo dd if=~/Downloads/Fedora-Live-Desktop-x86_64-20-1.iso of=/dev/disk2 bs=1m, this will take a bit of time, make sure you wait until it's done, additionally compare the size or checksum to make sure all has been copied (not that necessary since if it weren't copied, it'll err at boot time)
  5. use Disk Utility to shrink Mac's harddrive
