Why not run docker as root?
Running containers as root is a bad idea for security. This has been shown time and time again. Hackers find new ways of escaping out of the container, and that grants unfettered access to the host or Kubernetes node.
How do I know if sshd is enabled?
To check if SSH is enabled on your system, open a command prompt and end the command ssh . If it provides you with help for using SSH, it is already enabled! You should be able to follow the Linux instructions using the ssh-keygen command from the command prompt.
How do I access a Docker container from outside network?
Your Docker container can connect to the outside world, but the outside world cannot connect to the container. To make the ports accessible for external use or with other containers not on the same network, you will have to use the -P (publish all available ports) or -p (publish specific ports) flag.
Can I run Docker without admin rights?
While Docker Desktop on Windows can be run without having Administrator privileges, it does require them during installation. On installation the user gets a UAC prompt which allows a privileged helper service to be installed.
How to add SSH key in docker container?
In order to inject you ssh key, within a container, you have multiple solutions: Using a Dockerfile with the ADD instruction, you can inject it during your build process. Simply doing something like cat id_rsa | docker run -i <image> sh -c 'cat > /root/. ssh/id_rsa'
Can I SSH into a docker container?
So, if you want to get inside the box, you can't use SSH, because it doesn't exist in the container. You have to do something different. To be able to run commands inside a Docker container when it's running, use docker exec to start a shell, like sh or bash .
How to run a container in docker?
Start an app container
To do so, you will use the docker run command. You use the -d flag to run the new container in “detached” mode (in the background). You also use the -p flag to create a mapping between the host's port 3000 to the container's port 3000.
Is sshd same as OpenSSH?
sshd is the OpenSSH server process. It listens to incoming connections using the SSH protocol and acts as the server for the protocol. It handles user authentication, encryption, terminal connections, file transfers, and tunneling.
Where to put SSH key in docker container?
In order to inject you ssh key, within a container, you have multiple solutions: Using a Dockerfile with the ADD instruction, you can inject it during your build process. Simply doing something like cat id_rsa | docker run -i <image> sh -c 'cat > /root/. ssh/id_rsa'
How to open port 22 in docker container?
By default docker containers do not expose any ports. To expose port to your host you need to add the option: -p 22:22 to expose the port when you start running the container. To permanatly expose a port in Docker you need to edit the Dockerfile for the container and rebuild it.
