Fix DNS resolution in WSL2

Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.

To upgrade WSL, follow these steps,

  • 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.

Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command

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
