WSL2 and docker on dev machine

In my current development, I need Redis and rabbitmq containers in linux but they are consumed by windows application and containers. WSL provides a way to run linux and window containers at the same time. Here are the step to allow us to access both daemons from powershell.

This assumes the WSL2 is enabled and docker desktop is configured to take advantage of WSL.

Enable ssh in WSL

1. access wsl termial
2. modify /etc/ssh/sshd_config

   # change port number greater than 1000
   Port 2222
  ...
   # enable publickeyauthentication
   PubkeyAuthentication yes
   # enable password 
   PasswordAuthentication yes

3. start sshd

   sudo service ssh --full-restart
   sudo service ssh start

4. get wsl ip looking for eth0

   ip addr 

5. test ssh

in powershell

   ssh user@ip -p 2222
``

# set up public key authentication

 1. Generate key pair
 

ssh-keygen -t rsa

 2. add key to ssh-agent
 
   * start ssh-agent
  

start-service ssh-agent

   * mock sshd service

sc.exe create sshd binPath=C:\Windows\System32\OpenSSH\ssh.exe start-service sshd

  * add key

ssh-add

  
  3. copy public key to WSL

```(bash)
   cp /c/mnt/Users/userid/.ssh/id_rsa.pub ~/.ssh
   cat id_rsa.pub>>authorized_keys

4. test public key access

  
   ssh userid@ip -p 2222  
 

setup docker context

1. create config file at /Users/userid/.ssh folder

  Host wsl
     HostName 172.29.130.78
     User userid
     Port 2222
     IdentityFile ~/.ssh/id_rsa

2. test ssh config

  ssh wsl

3. create docker context

   docker context create wsl --docker host=ssh://wsl

4. switch context

   docker context use wsl
   docker info
