I am having issues related with xclip in a docker container.

echo "text" | xclip

which raises the error: Error: Can't open display: (null).

How can I programmatically add some text to host's clipboard from the container (in an OS independent way if possible)?

Thank you in advance.

UPDATE

DISPLAY env variable is not set. How can I set it correctly?

Maybe your $DISPLAY is not set. – Ashok Oct 23 '20 at 10:26
Yes, it is not @Ashok (sorry, I will update the question). But how can I set it up correctly? – J. Snow Oct 23 '20 at 12:33
DISPLAY=:0 xclip -sel clip < ~/.ssh/id_rsa.pub – Ashok Oct 23 '20 at 14:18
Should I do that in the container or in the host? – J. Snow Oct 23 '20 at 14:36
Furthermore, I do not have an SSH folder in my container – J. Snow Oct 23 '20 at 14:43
