Setup a Quick Postgres DB with Docker

docker run --name <db-name> -e POSTGRES_PASSWORD=admin -p 5432:5432 -d postgres

Set SSH for Multiple Accounts

Generate SSH

$ ssh-keygen -t ed25519 -C "[email protected]"

$ ssh-keygen -t ed25519 -C "[email protected]"

You should check if ed25519 is still the most recommended algorithm.

Copy SSH to Hosting Services

Copy output from each key using:

$ cat ~/.ssh/<your_geenrated_ssh_key>.pub

Create SSH Config File

Create file:

$ touch ~/.ssh/config

Open file with VSCode:

$ code ~/.ssh/config

Paste configuration

~/.ssh/config

Host work
  AddKeysToAgent yes
  HostName <work_host_name>
  User <work_user_name>
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<work_key>
  Port <port_number>

Host personal
  AddKeysToAgent yes
  HostName <personal_host_name>
  User <personal_user_name>
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<personal_key>
  Port <port_number>

Or

$ echo "Host work
  AddKeysToAgent yes
  HostName <work_host_name>
  User <work_user_name>
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<work_key>
  Port <port_number>

Host personal
  AddKeysToAgent yes
  HostName <personal_host_name>
  User <personal_user_name>
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<personal_key>
  Port <port_number>" > ~/.ssh/config

Add SSH

$ ssh-add <ssh_key_name>

Remove SSH

In case you need to remove it, you can do:

$ ssh-add -D

$ rm -rf ~/.ssh/*

Git Config and Workflow

You should create a root folder called repos, and inside of it, create two new folders.

• work - This folder you'll have all your work repositories
• personal - This folder you'll have all your personal repositories

Edit your git config file, and create two new ones for each of the folders above.

~/.gitconfig

[includeIf "gitdir:~/repos/work/"]
    path = ~/repos/work/.gitconfig
[includeIf "gitdir:~/repos/personal/"]
    path = ~/repos/personal/.gitconfig

~/repos/work/.gitconfig

[user]
	email = [email protected]
	name = Your Name

~/repos/personal/.gitconfig

[user]
	email = [email protected]
	name = Your Name

Clone Repository

To clone any repository now, public or private, use this command:

git clone git@<your_host_name>:<remote_repository_name>

Example

If the git repository tells you to clone like this: [email protected]:nodejs/node.git

You should use this command instead:

git clone git@work:nodejs/node.git

or

git clone git@personal:nodejs/node.git

Check the Git User Email Inside the Repository

$ git config --show-origin --get user.email
