What if I lost my EC2 ssh key?

For EBS backed instances

1 - Best option

Run the AWSSupport-ResetAccess automation document via AWS Systems Manager.
Detailed doc here

2 - Modify ssh authorized keys

Add --allow-privileged=true to:

# kubelet config
sudo vim /var/snap/microk8s/current/args/kubelet

#kube-apiserver config
sudo vim /var/snap/microk8s/current/args/kube-apiserver

Restart services:

S3 bucket to private user

Create a IAM policy called s3-admin-nexus-s3-bucket. It will be used later.

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Go to https://www.autohotkey.com/download/ On your desktop, right-click on an empty space and select "AutoHotkey Script" inside the "New" menu. Give the script a name (e.g. AlwaysOnTop) and save it. Right-click on the script and select "Edit Script". Replace the content of the file with the following code:

#Space:: Winset, AlwaysOnTop, Toggle, A

Save the file.
