Hello All, I want to use docker but I am confused about how docker is secure? A lack of security has always been a problem for containers. Without a way to verify the authenticity of images and containers, Docker's domain of application is seriously limited? Can anyone know any tutorial for docker in the free version, I want to clear my doubts, Please suggest me some tutorials.
Docker containers are, by default, quite secure; especially if you run your processes as non-privileged users inside the container. You can add an extra layer of safety by enabling AppArmor, SELinux, GRSEC, or another appropriate hardening system. You can start from these Docker Tutorials
