I made hadoop image based on centos using dockerfile. There are 4 nodes. I want to configure cluster using ssh-copy-id. But an error has occurred.
ERROR: ssh: connect to host [ip] port 22: Connection refused
How can I solve this problem?
ssh
follows a client-server architecture. So, the openssh-server
has to be installed in the container. Now ssh-copy-id
and other commands should run if the ip address is routable.
