[20XX-XX-XX] Service Name downtime

This is a blameless Post-mortem.
We will not focus on the past events as they pertain to "could've", "should've", etc.
All follow up action items will be assigned to a team/individual before the end of the meeting.
If the item is not going to be top priority leaving the meeting, don't make it a follow up item.

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Setup GitHub repository SSH deploy keys

Create GitHub repository in github and save the SSH repository url
Init git on server in code directory

git init

Create SSH keys on the server

ssh-keygen -t rsa -b 4096 -C [email protected]
Rename the key that doesn't end with .pub to repo-name.deploy.pem

	curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg \| sudo apt-key add -
	echo "step1"
	echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" \| sudo tee /etc/apt/sources.list.d/kubernetes.list
	echo "kubeadm install"
	sudo apt update -y
	sudo apt -y install vim git curl wget kubelet=1.24.3-00 kubeadm=1.24.3-00 kubectl=1.24.3-00
	echo "memory swapoff"
	sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
	sudo swapoff -a
	sudo modprobe overlay

	More recent resolution:

	1. cd ~/../../etc (go to etc folder in WSL).
	2. echo "[network]" \| sudo tee wsl.conf (Create wsl.conf file and add the first line).
	3. echo "generateResolvConf = false" \| sudo tee -a wsl.conf (Append wsl.conf the next line).
	4. wsl --terminate Debian (Terminate WSL in Windows cmd, in case is Ubuntu not Debian).
	5. cd ~/../../etc (go to etc folder in WSL).
	6. sudo rm -Rf resolv.conf (Delete the resolv.conf file).
	7. In windows cmd, ps or terminal with the vpn connected do: Get-NetIPInterface or ipconfig /all for get the dns primary and
	secondary.
