Add `non root` user on docker host and enable ssh access

Back

I don’t want to have to work with the root user on my Docker host. For this reason, I always create a dedicated user who must also be authorised for the Docker daemon.

These are the necessary steps:

Add the new user (and give him a proper password):

adduser network
Adding user 'network' ...
Adding new group 'network' (1002) ...
Adding new user 'network' (1002) with group 'network' ...
Creating home directory '/home/network' ...
Copying files from '/etc/skel' ...
New password: 
Retype new password: 
passwd: password updated successfully
Changing the user information for network
Enter the new value, or press ENTER for the default
     Full Name []: 
     Room Number []: 
     Work Phone []: 
     Home Phone []: 
     Other []: 
Is the information correct? [Y/n]

Add the newly created user to the sudo group:
```
usermod -aG sudo docker network
```
Verify the group memberships of the network user:
```
groups network
network : network sudo
```
Switch to the network user
```
su - network
```
Verify the sudo command:
```
sudo ls /root
```
This should work without any errors!
Create a .ssh folder in the home directory
```
mkdir ~/.ssh
```
Edit the ~/.ssh/authorized_keys file and paste your public SSH key:
```
nano ~/.ssh/authorized_keys
```
If you haven’t any SSH keys yet you can easly create on on windows with the ssh-keygen command:
Secure your ~/.ssh/authorized_keys file with just owner read/write permissions:
```
chmod 600 ~/.ssh/authorized_keys
```
Test the ssh connection from the work computer:
```
 ssh network@docker.local
```
If you aren’t using your default ssh key for the connection then you have to use the -i parameter to use the correct private key. e.g.:
```
 ssh -i <path to your private ssh key> network@docker.local
```
