Magento 2 | Connect with CLI on online server or docker container

I need to connect the Magento 2 CLI to an on line server:

ONLINE SERVER

1° open the terminal
2° connect to shh by typing this command

00001
00002
00003
ssh ssh_username@ssh_host -p ssh_port
ex:
ssh magentobp@magento.beprime.it -p 45000

basically the command is

00001
00002
00003
ssh | the ssh command
magentobp@magento.beprime.it | ssh_username followed by @ and the server where you want connect
-p 45000 | -p followed by the ssh port of you server

Now the system ask for a ssh password, something like this :

00001
00002
00003
00004
00005
magentobp@magento.beprime.it's password:
</code>
insert ssh password, and if all is right the server responded something like :
 
Last login: Fri Jan 11 12:57:47 2019 from 212.183.165.53

Last thing, navigate to the Magento installation root

00001
cd /home/magentobp/public_html

DOCKER CONTAINER

1° open the terminal
2° connect to shh by typing this command

00001
00002
docker exec -it magento_2_webserver_1 /bin/bash
su beprime (utente beprime )

From now you can use the CLI commands.

That’s all
