Docker Swarm IP Table

Add New Docker User

*BOBPAT = placeholder name

*Must be done on each docker node

1. Escalate to superuser

sudo su -

2. Add the user

sudo adduser BOBpat (set the password to something easy i.e. password // can also be changed in /etc/passwd)

3. Give user permission to the docker and sudoers group

sudo usermod -aG docker BOBpat
sudo usermod -aG sudo BOBpat

4. Connect to user’s account and import user’s github keys

su BOBpat
ssh-import-id-gh [BOBPAT GITHUB USERNAME]

5. Test whether or not the user can connect to each docker swarm:

ssh BOB@192.PAT@192.168.1.64
ssh BOB@192.PAT@192.168.1.65
ssh BOB@192.PAT@192.168.1.66

6. Have user change their password NOT ON ROOT:

passwd (change on each docker node)
