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 refusedHow 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.
