Generate an SSH key and use it to log into a user on a new server. Generate an SSH Key. Containers, like Docker, allow developers to isolate and run multiple applications on a single operating system, rather than dedicating a Virtual Machine for each application on the server. When the container runs for the first time, it will install Jenkins. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. Execute command. The hostname for that container is the container ID: $ ssh [email protected] -p 2222 The authenticity of host '[localhost]:2222 ([::1]:2222)' can't be established.
