What is an SSH Key?
SSH Key is an access credential similar to a username and password. These keys are mainly used in any automating process. SSH keys have two parts: public key and private key. Here the private key is placed on the host machine while the public key is placed on the server. Whenever the host machine tries to access the server, here first the server recognizes someone is trying to access the server. So in response server sends an encrypted message with the public key to the host machine and then the host machine will decrypt it with its private key correctly to get access to the server. This whole process is automatic without any manual user intervention. After this host machine can successfully access the server. These SSH keys enhance security by using strong cryptographic algorithms. These are widely used in the automated process. SSH key also reduces the overhead of password management for managing access to multiple servers. In summary, we can say SSH keys are important tools for secure remote access to a server.
How To Use SSH Keys Inside Docker Container?
SSH key is a credential used for remote access of servers without using any type of username and password and Docker is a containerization tool used to encapsulate the application with its dependencies into compact units called docker containers. In this guide, I will first discuss what is SSH key and how it works. Then I will discuss docker. After that, I will walk you through the different steps to use SSH keys inside a docker container.
