Getting a Shell in the Docker Desktop Mac VM

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

Change ownership of selected older commits in Git
  1. Clone the repo.
  2. Use git rebase -i --root
  3. vim will open. Select the commits you want to modify by changing pick to edit. If you would like to change all the commits, perform the following replace: :%s/^pick/edit/g. This command changes all instances of "pick" at the start of lines to "edit".
  4. You will now be shown all the selected commits one by one. Each commit message will be displayed. You have two options:
    • If you would like to keep the commit author details the same, do a git rebase --continue.
    • If you would like to change it to a different name/email, do git commit --amend --reset-author. If --reset-author is specified, it will use the details from your git config. (If you need to specify an alternate name/email, you can do so with --author="John Doe <john@example.com>". If you would like to change the time to a previous date, you can do so with --date "2 days ago".)
  5. Do the same for all the commits and finish the rebase.
  6. Perform git push -f origin master to

A SaltStack AWS Auto Scaling Solution

A SaltStack AWS Auto Scaling Solution

Overview

The AWS Auto Scaling Goup, configured with a customised Cloud-Init file, sends a notification to an SNS Topic, which in turn passes it onto an SQS queue that the Salt Master is subscribed to. A Reactor watches for the auto scaling events and pre-approves the new minion based on its Auto Scaling group name and instance ID.
